CONTRACTOR and any Subcontractor or Supplier or other individual or entity performing or furnishing any of the Work under a direct or indirect contract with OWNER: (i) shall not have or acquire any title to or ownership rights in any of the Drawings, Specifications, or other documents (or copies of any thereof) prepared by or bearing the seal of ENGINEER or ENGINEER's Consultant, including electronic media editions; and (ii) shall not reuse any of such Drawings, Specifications, other documents, or copies thereof on extensions of the Project or any other project without written consent of OWNER and ENGINEER and specific written verification or adaption by ENGINEER. This prohibition will survive final payment, completion, and acceptance of the Work, or termination or completion of the Contract. Nothing herein shall preclude CONTRACTOR from retaining copies of the Contract Documents for record purposes. ARTICLE 4 - AVAILABILITY OF LANDS; SUBSURFACE AND PHYSICAL CONDITIONS; REFERENCE POINTS 4.01 Availability of Lands A. OWNER shall furnish the Site. OWNER shall notify CONTRACTOR of any encumbrances or restrictions not of general application but specifically related to use of the Site with which CONTRACTOR must comply in performing the Work. OWNER will obtain in a timely manner and pay for easements for permanent structures or permanent changes in existing facilities. If CONTRACTOR and OWNER are unable to agree on entitlement to or on the amount or extent, if any, of any adjustment in the Contract Price or Contract Times, or both, as a result of any delay in OWNER's furnishing the Site, CONTRACTOR may make a Claim therefor as provided in paragraph 10.05. 00700 - 11 2. CONTRACTOR shall not be entitled to any adjustment in the Contract Price or Contract Times if: a. CONTRACTOR knew of the existence of such conditions at the time CONTRACTOR made a final commitment to OWNER in respect of Contract Price and Contract Times by the submission of a Bid or becoming bound under a negotiated contract; or b. the existence of such condition could reasonably have been discovered or revealed as a result of any examination, investigation, exploration, test, or study of the Site and contiguous areas required by the Bidding Requirements or Contract Documents to be conducted by or for CON- TRACTOR prior to CONTRACTOR's making such final commitment; or c. CONTRACTOR failed to give the written notice within the time and as required by paragraph 4.03.A. 3. If OWNER and CONTRACTOR are unable to agree on entitlement to or on the amount or extent, if any, of any adjustment in the Contract Price or Contract Times, or both, a Claim may be made therefor as provided in paragraph 10.05. However, OWNER, ENGINEER, and ENGINEER's Consultants shall not be liable to CONTRACTOR for any claims, costs, losses, or damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) sustained by CONTRACTOR on or in connection with any other project or anticipated project. 4.04 Underground Facilities A. Shown or Indicated: The information and data shown or indicated in the Contract Documents with respect to existing Underground Facilities at or contiguous to the Site is based on information and data furnished to OWNER or ENGINEER by the owners of such Underground Facilities, including OWNER, or by others. Unless it is otherwise expressly provided in the Supplementary Conditions: 1. OWNER and ENGINEER shall not be responsible for the accuracy or completeness of any such information or data; and 2. the cost of all of the following will be included in the Contract Price, and CONTRACTOR shall have full responsibility for: a. reviewing and checking all such information and data, B. b. locating all Underground Facilities shown or indicated in the Contract Documents, c. coordination of the Work with the owners of such Underground Facilities, including OWNER, during construction, and d. the safety and protection of all such Under- ground Facilities and repairing any damage thereto resulting from the Work. Not Shown or Indicated 1. If an Underground Facility is uncovered or revealed at or contiguous to the Site which was not shown or indicated, or not shown or indicated with reasonable accuracy in the Contract Documents, CONTRACTOR shall, promptly after becoming aware thereof and before further disturbing conditions affected thereby or performing any Work in connection therewith (except in an emergency as required by paragraph 6.16.A), identify the owner of such Underground Facility and give written notice to that owner and to OWNER and ENGINEER. ENGINEER will promptly review the Underground Facility and determine the extent, if any, to which a change is required in the Contract Documents to reflect and document the consequences of the existence or location of the Underground Facility. During such time, CONTRACTOR shall be responsible for the safety and protection of such Underground Facility. 2. If ENGINEER concludes that a change in the Contract Documents is required, a Work Change Directive or a Change Order will be issued to reflect and document such consequences. An equitable adjustment shall be made in the Contract Price of Contract Times, or both, to the extent that they are attributable to the existence or location of any Underground Facility that was not shown or indicated or not shown or indicated with reasonable accuracy in the Contract Documents and that CONTRACTOR did not know of and could not reasonably have been expected to be aware of or to have anticipated. If OWNER and CONTRACTOR are unable to agree on entitlement to or on the amount or extent, if any, of any such adjustment in Contract Price or Contract Times, OWNER or CONTRACTOR may make a Claim therefor as provided in paragraph 10.05. 4.05 Reference Points A. OWNER shall provide engineering surveys to establish reference points for construction which in ENGINEER's judgment are necessary to enable CON- TRACTOR to proceed with the Work. CONTRACTOR shall be responsible for laying out the Work, shall protect and preserve the established reference points and property 00700 - 13 in this paragraph 4.06.E shall obligate OWNER to indemnify any individual or entity from and against the consequences of that individual's or entity's own negligence.

Nothing in this paragraph 4.06.F shall obligate CONTRACTOR to indemnify any individual or entity from and against the consequences of that individual's or entity's own negligence. I. The provisions of paragraphs 4.02, 4.03, and 4.04 are not intended to apply to a Hazardous Environmental Condition uncovered or revealed at the Site. ARTICLE 5 - BONDS AND INSURANCE 5.01 Performance, Payment, and Other Bonds A. CONTRACTOR shall furnish performance and payment Bonds, each in an amount at least equal to the Contract Price as security for the faithful performance and payment of all CONTRACTOR's obligations under the Contract Documents.

CONTRACTOR shall also furnish such other Bonds as are required by the Contract Documents. B. All Bonds shall be in the form prescribed by the Contract Documents except as provided otherwise by Laws or Regulations, and shall be executed by such sureties as are named in the current list of "Companies Holding Certificates of Authority as Acceptable Sureties on Federal Bonds and as Acceptable Reinsuring Companies" as published in Circular 570 (amended) by the Financial Management Service, Surety Bond Branch, U.S. Department of the Treasury. All Bonds signed by an agent must be accompanied by a certified copy of such agent's authority to act. C. If the surety on any Bond furnished by CON- TRACTOR is declared bankrupt or becomes insolvent or its right to do business is terminated in any state where any part of the Project is located or it ceases to meet the requirements of paragraph 5.01.B, CONTRACTOR shall within 20 days thereafter substitute another Bond and surety, both of which shall comply with the requirements of paragraphs 5.01.B and 5.02. 5.02 Licensed Sureties and Insurers A. All Bonds and insurance required by the Contract Documents to be purchased and maintained by OWNER or CONTRACTOR shall be obtained from surety or insurance companies that are duly licensed or authorized in the jurisdiction in which the Project is located to issue Bonds or insurance policies for the limits and coverages so required. Such surety and insurance companies shall also meet such additional requirements and qualifications as may be provided in the Supplementary Conditions. 5.03 Certificates of Insurance A.

CONTRACTOR shall purchase and maintain such liability and other insurance as is appropriate for the Work being performed and as will provide protection from claims set forth below which may arise out of or result from CONTRACTOR's performance • of the Work and CONTRACTOR's other obligations under the Contract Documents, whether it is to be performed by CONTRACTOR, any Subcontractor or Supplier, or by anyone directly or indirectly employed by any of them to perform any of the Work, or by anyone for whose acts any of them may be liable: 1. claims under workers' compensation, disability benefits, and other similar employee benefit acts; 2. claims for damages because of bodily injury, occupational sickness or disease, or death of CONTRACTOR's employees; 3. claims for damages because of bodily injury, sickness or disease, or death of any person other than CONTRACTOR's employees; 00700 - 15 4. cover materials and equipment stored at the Site or at another location that was agreed to in writing by OWNER prior to being incorporated in the Work, provided that such materials and equipment have been included in an Application for Payment recommended by ENGINEER; 5. allow for partial utilization of the Work by OWNER; 6. include testing and startup; and 7. be maintained in effect until final payment is made unless otherwise agreed to in writing by OWNER, CONTRACTOR, and ENGINEER with 30 days written notice to each other additional insured to whom a certifi- cate of insurance has been issued. B. OWNER shall purchase and maintain such boiler and machinery insurance or additional property insurance as may be required by the Supplementary Conditions or Laws and Regulations which will include the interests of OWNER, CONTRACTOR, Subcontractors, ENGINEER, ENGINEER's Consultants, and any other individuals or entities identified in the Supplementary Conditions, each of whom is deemed to have an insurable interest and shall be listed as an insured or additional insured. C. All the policies of insurance (and the certificates or other evidence thereof) required to be purchased and maintained in accordance with paragraph 5.06 will contain a provision or endorsement that the coverage afforded will not be canceled or materially changed or renewal refused until at least 30 days prior written notice has been given to OWNER and CONTRACTOR and to each other additional insured to whom a certificate of insurance has been issued and will contain waiver provisions in accordance with paragraph 5.07. D. OWNER shall not be responsible for purchasing and maintaining any property insurance specified in this paragraph 5.06 to protect the interests of CONTRACTOR, Subcontractors, or others in the Work to the extent of any deductible amounts that are identified in the Supplementary Conditions. The risk of loss within such identified deductible amount will be borne by CONTRACTOR, Subcontractors, or others suffering any such loss, and if any of them wishes property insurance coverage within the limits of such amounts, each may purchase and maintain it at the purchaser's own expense. E. If CONTRACTOR requests in writing that other special insurance be included in the property insurance policies provided under paragraph 5.06, OWNER shall, if possible, include such insurance, and the cost thereof will be charged to CONTRACTOR by appropriate Change Order or Written Amendment. Prior to commencement of the Work at the Site, OWNER shall in writing advise CONTRACTOR whether or not such other insurance has been procured by OWNER. 5.07 Waiver of Rights A. OWNER and CONTRACTOR intend that all policies purchased in accordance with paragraph 5.06 will protect OWNER, CONTRACTOR, Subcontractors, ENGINEER, ENGINEER's Consultants, and all other individuals or entities identified in the Supplementary Conditions to be listed as insureds or additional insureds (and the officers, directors, partners, employees, agents, and other consultants and subcontractors of each and any of them) in such policies and will provide primary coverage for all losses and damages caused by the perils or causes of loss covered thereby. All such policies shall contain provisions to the effect that in the event of payment of any loss or damage the insurers will have no rights of recovery against any of the insureds or additional insureds thereunder. OWNER and CONTRAC- TOR waive all rights against each other and their respective officers, directors, partners, employees, agents, and other consultants and subcontractors of each and any of them for all losses and damages caused by, arising out of or resulting from any of the perils or causes of loss covered by such policies and any other property insurance applicable to the Work; and, in addition, waive all such rights against Subcontractors, ENGINEER, ENGINEER's Consultants, and all other individuals or entities identified in the Supplemen- tary Conditions to be listed as insureds or additional insureds (and the officers, directors, partners, employees, agents, and other consultants and subcontractors of each and any of them) under such policies for losses and damages so caused. None of the above waivers shall extend to the rights that any party making such waiver may have to the proceeds of insurance held by OWNER as trustee or otherwise payable under any policy so issued. B. OWNER waives all rights against CONTRACTOR, Subcontractors, ENGINEER, ENGINEER's Consultants, and the officers, directors, partners, employees, agents, and other consultants and subcontractors of each and any of them for: 1. loss due to business interruption, loss of use, or other consequential loss extending beyond direct physical loss or damage to OWNER's property or the Work caused by, arising out of, or resulting from fire or other peril whether or not insured by OWNER; and 2. loss or damage to the completed Project or part thereof caused by, arising out of, or resulting from fire or other insured peril or cause of loss covered by any property insurance maintained on the completed Project or part thereof by OWNER during partial utilization pursuant to paragraph 14.05, after Substantial Completion 00700 - 17 6.02 Labor; Working Hours A. CONTRACTOR shall provide competent, suitably qualified personnel to survey, lay out, and construct the Work as required by the Contract Documents. CON- TRACTOR shall at all times maintain good discipline and order at the Site. B. Except as otherwise required for the safety or protection of persons or the Work or property at the Site or adjacent thereto, and except as otherwise stated in the Contract Documents, all Work at the Site shall be performed during regular working hours, and CONTRACTOR will not permit overtime work or the performance of Work on Saturday, Sunday, or any legal holiday without OWNER's written consent (which will not be unreasonably withheld) given after prior written notice to ENGINEER. 6.03 Services, Materials, and Equipment A. Unless otherwise specified in the General Re- quirements, CONTRACTOR shall provide and assume full responsibility for all services, materials, equipment, labor, transportation, construction equipment and machinery, tools, appliances, fuel, power, light, heat, telephone, water, sanitary facilities, temporary facilities, and all other facilities and incidentals necessary for the performance, testing, start-up, and completion of the Work. B. All materials and equipment incorporated into the Work shall be as specified or, if not specified, shall be of good quality and new, except as otherwise provided in the Contract Documents. All warranties and guarantees specifically called for by the Specifications shall expressly run to the benefit of OWNER. If required by ENGINEER, CONTRACTOR shall furnish satisfactory evidence (including reports of required tests) as to the source, kind, and quality of materials and equipment. All materials and equipment shall be stored, applied, installed, connected, erected, protected, used, cleaned, and conditioned in accordance with instructions of the applicable Supplier, except as otherwise may be provided in the Contract Docu- ments. 6.04 Progress Schedule A. CONTRACTOR shall adhere to the progress schedule established in accordance with paragraph 2.07 as it may be adjusted from time to time as provided below. 1. CONTRACTOR shall submit to ENGINEER for acceptance (to the extent indicated in paragraph 2.07) proposed adjustments in the progress schedule that will not result in changing the Contract Times (or Milestones). Such adjustments will conform generally to the progress schedule then in effect and additionally will comply with any provisions of the General Requirements applicable thereto. 2. Proposed adjustments in the progress schedule that will change the Contract Times (or Milestones) shall be submitted in accordance with the requirements of Article 12. Such adjustments may only be made by a Change Order or Written Amendment in accordance with Article 12. 6.05 Substitutes and "Or -Equals" A. Whenever an item of material or equipment is specified or described in the Contract Documents by using the name of a proprietary item or the name of a particular Supplier, the specification or description is intended to establish the type, function, appearance, and quality required. Unless the specification or description contains or is followed by words reading that no like, equivalent, or "or -equal" item or no substitution is permitted, other items of material or equipment or material or equipment of other Suppliers may be submitted to ENGINEER for review under the circum- stances described below. 1. "Or -Equal" Items: If in ENGINEER's sole discretion an item of material or equipment proposed by CONTRACTOR is functionally equal to that named and sufficiently similar so that no change in related Work will be required, it may be considered by ENGINEER as an "or -equal" item, in which case review and approval of the proposed item may, in ENGINEER's sole discretion, be accomplished without compliance with some or all of the requirements for approval of proposed substitute items. For the purposes of this paragraph 6.05.A.1, a proposed item of material or equipment will be considered functionally equal to an item so named if: a. in the exercise of reasonable judgment ENGINEER determines that: (i) it is at least equal in quality, durability, appearance, strength, and design characteristics; (ii) it will reliably perform at least equally well the function imposed by the design concept of the completed Project as a functioning whole, and; b. CONTRACTOR certifies that: (i) there is no increase in cost to the OWNER; and (ii) it will conform substantially, even with deviations, to the detailed requirements of the item named in the Contract Documents. 2. Substitute Items a. If in ENGINEER's sole discretion an item of material or equipment proposed by CONTRACTOR does not qualify as an "or -equal" item under 00700 - 19 entities to be submitted to OWNER in advance for acceptance by OWNER by a specified date prior to the Effective Date of the Agreement, and if CONTRACTOR has submitted a list thereof in accordance with the Supplementary Conditions, OWNER's acceptance (either in writing or by failing to make written objection thereto by the date indicated for acceptance or objection in the Bidding Documents or the Contract Documents) of any such Subcontractor, Supplier, or other individual or entity so identified may be revoked on the basis of reasonable objection after due investigation. CON- TRACTOR shall submit an acceptable replacement for the rejected Subcontractor, Supplier, or other individual or entity, and the Contract Price will be adjusted by the differ- ence in the cost occasioned by such replacement, and an appropriate Change Order will be issued or Written Amendment signed. No acceptance by OWNER of any such Subcontractor, Supplier, or other individual or entity, whether initially or as a replacement, shall constitute a waiver of any right of OWNER or ENGINEER to reject defective Work. C. CONTRACTOR shall be fully responsible to OWNER and ENGINEER for all acts and omissions of the Subcontractors, Suppliers, and other individuals or entities performing or furnishing any of the Work just as CONTRACTOR is responsible for CONTRACTOR's own acts and omissions. Nothing in the Contract Documents shall create for the benefit of any such Subcontractor, Supplier, or other individual or entity any contractual relationship between OWNER or ENGINEER and any such Subcontractor, Supplier or other individual or entity, nor shall it create any obligation on the part of OWNER or ENGINEER to pay or to see to the payment of any moneys due any such Subcon- tractor, Supplier, or other individual or entity except as may otherwise be required by Laws and Regulations. D. CONTRACTOR shall be solely responsible for scheduling and coordinating the Work of Subcontractors, Suppliers, and other individuals or entities performing or furnishing any of the Work under a direct or indirect contract with CONTRACTOR. E. CONTRACTOR shall require all Subcontractors, Suppliers, and such other individuals or entities performing or furnishing any of the Work to communicate with ENGI- NEER through CONTRACTOR. F. The divisions and sections of the Specifications and the identifications of any Drawings shall not control CONTRACTOR in dividing the Work among Subcontractors or Suppliers or delineating the Work to be performed by any specific trade. G. All Work performed for CONTRACTOR by a Subcontractor or Supplier will be pursuant to an appropriate agreement between CONTRACTOR and the Subcontractor or Supplier which specifically binds the Subcontractor or Supplier to the applicable terms and conditions of the Contract Documents for the benefit of OWNER and ENGINEER. Whenever any such agreement is with a Subcontractor or Supplier who is listed as an additional insured on the property insurance provided in paragraph 5.06, the agreement between the CONTRACTOR and the Subcontractor or Supplier will contain provisions whereby the Subcontractor or Supplier waives all rights against OWNER, CONTRACTOR, ENGINEER, ENGINEER's Consultants, and all other individuals or entities identified in the Supplementary Conditions to be listed as insureds or additional insureds (and the officers, directors, partners, employees, agents, and other consultants and subcontractors of each and any of them) for all losses and damages caused by, arising out of, relating to, or resulting from any of the perils or causes of loss covered by such policies and any other property insurance applicable to the Work. If the insurers on any such policies require separate waiver forms to be signed by any Subcontractor or Supplier, CONTRAC- TOR will obtain the same. 6.07 Patent Fees and Royalties A. CONTRACTOR shall pay all license fees and royalties and assume all costs incident to the use in the performance of the Work or the incorporation in the Work of any invention, design, process, product, or device which is the subject of patent rights or copyrights held by others. If a particular invention, design, process, product, or device is specified in the Contract Documents for use in the performance of the Work and if to the actual knowledge of OWNER or ENGINEER its use is subject to patent rights or copyrights calling for the payment of any license fee or royalty to others, the existence of such rights shall be disclosed by OWNER in the Contract Documents. To the fullest extent permitted by Laws and Regulations, CONTRACTOR shall indemnify and hold harmless OWNER, ENGINEER, ENGINEER's Consultants, and the officers, directors, partners, employees or agents, and other consultants of each and any of them from and against all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to any infringement of patent rights or copyrights incident to the use in the performance of the Work or resulting from the incorporation in the Work of any invention, design, process, product, or device not specified in the Contract Documents. 6.08 Permits A. Unless otherwise provided in the Supplementary Conditions, CONTRACTOR shall obtain and pay for all construction permits and licenses. OWNER shall assist CONTRACTOR, when necessary, in obtaining such permits 00700 - 21 Change Directives, Field Orders, and written interpretations and clarifications in good order and annotated to show changes made during construction. These record documents together with all approved Samples and a counterpart of all approved Shop Drawings will be available to ENGINEER for reference. Upon completion of the Work, these record documents, Samples, and Shop Drawings will be delivered to ENGINEER for OWNER. 6.13 Safety and Protection A. CONTRACTOR shall be solely responsible for initiating, maintaining and supervising all safety precautions and programs in connection with the Work. CONTRACTOR shall take all necessary precautions for the safety of, and shall provide the necessary protection to prevent damage, injury or loss to: 1. all persons on the Site or who may be affected by the Work; 2. all the Work and materials and equipment to be incorporated therein, whether in storage on or off the Site; and 3. other property at the Site or adjacent thereto, including trees, shrubs, lawns, walks, pavements, roadways, structures, utilities, and Underground Facilities not designated for removal, relocation, or replacement in the course of construction. B. CONTRACTOR shall comply with all applicable Laws and Regulations relating to the safety of persons or property, or to the protection of persons or property from damage, injury, or loss; and shall erect and maintain all necessary safeguards for such safety and protection. CONTRACTOR shall notify owners of adjacent property and of Underground Facilities and other utility owners when prosecution of the Work may affect them, and shall cooperate with them in the protection, removal, relocation, and replacement of their property. All damage, injury, or loss to any property referred to in paragraph 6.13.A.2 or 6.13.A.3 caused, directly or indirectly, in whole or in part, by CON- TRACTOR, any Subcontractor, Supplier, or any other individual or entity directly or indirectly employed by any of them to perform any of the Work, or anyone for whose acts any of them may be liable, shall be remedied by CONTRACTOR (except damage or loss attributable to the fault of Drawings or Specifications or to the acts or omissions of OWNER or ENGINEER or ENGINEER's Con- sultant, or anyone employed by any of them, or anyone for whose acts any of them may be liable, and not attributable, directly or indirectly, in whole or in part, to the fault or negligence of CONTRACTOR or any Subcontractor, Supplier, or other individual or entity directly or indirectly employed by any of them) . CONTRACTOR's duties and responsibilities for safety and for protection of the Work shall continue until such time as all the Work is completed and ENGINEER has issued a notice to OWNER ' and CONTRACTOR in accordance with paragraph 14.07.B that the Work is acceptable (except as otherwise expressly provided in connection with Substantial Completion) . 6.14 Safety Representative A. CONTRACTOR shall designate a qualified and experienced safety representative at the Site whose duties and responsibilities shall be the prevention of accidents and the maintaining and supervising of safety precautions and programs. 6.15 Hazard Communication Programs A. CONTRACTOR shall be responsible for coordinating any exchange of material safety data sheets or other hazard communication information required to be made available to or exchanged between or among employers at the Site in accordance with Laws or Regulations. 6.16 Emergencies A. In emergencies affecting the safety or protection of persons or the Work or property at the Site or adjacent thereto, CONTRACTOR is obligated to act to prevent threatened damage, injury, or loss. CONTRACTOR shall give ENGINEER prompt written notice if CONTRACTOR believes that any significant changes in the Work or variations from the Contract Documents have been caused thereby or are required as a result thereof. If ENGINEER determines that a change in the Contract Documents is required because of the action taken by CONTRACTOR in response to such an emergency, a Work Change Directive or Change Order will be issued. 6.17 Shop Drawings and Samples A. CONTRACTOR shall submit Shop Drawings to ENGINEER for review and approval in accordance with the acceptable schedule of Shop Drawings and Sample submittals. All submittals will be identified as ENGINEER may require and in the number of copies specified in the General Requirements. The data shown on the Shop Drawings will be complete with respect to quantities, dimen- sions, specified performance and design criteria, materials, and similar data to show ENGINEER the services, materials, and equipment CONTRACTOR proposes to provide and to enable ENGINEER to review the information for the limited purposes required by paragraph 6.17. E. B. CONTRACTOR shall also submit Samples to ENGINEER for review and approval in accordance with the acceptable schedule of Shop Drawings and Sample 00700 - 23 as permitted by paragraph 15.04 or as OWNER and CONTRACTOR may otherwise agree in writing. 6.19 CONTRACTOR's General Warranty and Guarantee A. CONTRACTOR warrants and guarantees to OWNER, ENGINEER, and ENGINEER's Consultants that all Work will be in accordance with the Contract Documents and will not be defective. CONTRACTOR's warranty and guarantee hereunder excludes defects or damage caused by: 1. abuse, modification, or improper maintenance or operation by persons other than CONTRACTOR, Sub- contractors, Suppliers, or any other individual or entity for whom CONTRACTOR is responsible; or 2. normal wear and tear under normal usage. B. CONTRACTOR's obligation to perform and complete the Work in accordance with the Contract Documents shall be absolute. None of the following will constitute an acceptance of Work that is not in accordance with the Contract Documents or a release of CONTRACTOR's obligation to perform the Work in accordance with the Contract Documents: 1. observations by ENGINEER; 2. recommendation by ENGINEER or payment by OWNER of any progress or final payment; 3. the issuance of a certificate of Substantial Completion by ENGINEER or any payment related thereto by OWNER; 4. use or occupancy of the Work or any part thereof by OWNER; 5. any acceptance by OWNER or any failure to do so; 6. any review and approval of a Shop Drawing or Sample submittal or the issuance of a notice of acceptabil- ity by ENGINEER; 7. any inspection, test, or approval by others; or 8. any correction of defective Work by OWNER. 6.20 Indemnification A. To the fullest extent permitted by Laws and Regula- tions, CONTRACTOR shall indemnify and hold harmless OWNER, ENGINEER, ENGINEER's Consultants, and the officers, directors, partners, employees, agents, and other consultants and subcontractors of each and any of them from and against all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to the performance of the Work, provided that any such claim, cost, loss, or damage: 1. is attributable to bodily injury, sickness, disease, or death, or to injury to or destruction of tangible property (other than the Work itself), including the loss of use resulting therefrom; and 2. is caused in whole or in part by any negligent act or omission of CONTRACTOR, any Subcontractor, any Supplier, or any individual or entity directly or indirectly employed by any of them to perform any of the Work or anyone for whose acts any of them may be liable, regardless of whether or not caused in part by any negligence or omission of an individual or entity indem- nified hereunder or whether liability is imposed upon such indemnified party by Laws and Regulations regardless of the negligence of any such individual or entity. B. In any and all claims against OWNER or ENGINEER or any of their respective consultants, agents, officers, directors, partners, or employees by any employee (or the survivor or personal representative of such employee) of CONTRACTOR, any Subcontractor, any Supplier, or any individual or entity directly or indirectly employed by any of them to perform any of the Work, or anyone for whose acts any of them may be liable, the indemnification obligation under paragraph 6.20.A shall not be limited in any way by any limitation on the amount or type of damages, compensation, or benefits payable by or for CONTRACTOR or any such Subcontractor, Supplier, or other individual or entity under workers' compensation acts, disability benefit acts, or other employee benefit acts. C. The indemnification obligations of CONTRACTOR under paragraph 6.20.A shall not extend to the liability of ENGINEER and ENGINEER's Consultants or to the officers, directors, partners, employees, agents, and other consultants and subcontractors of each and any of them arising out of: 1. the preparation or approval of, or the failure to prepare or approve, maps, Drawings, opinions, reports, surveys, Change Orders, designs, or Specifications; or 2. giving directions or instructions, or failing to give them, if that is the primary cause of the injury or damage. 00700 - 25 and tests of subsurface conditions and drawings of physical conditions in or relating to existing surface or subsurface structures at or contiguous to the Site that have been utilized by ENGINEER in preparing the Contract Documents. 8.06 Insurance A.

ARTICLE 9 - ENGINEER'S STATUS DURING CONSTRUCTION 9.01 OWNER'S Representative A. ENGINEER will be OWNER's representative during the construction period. The duties and responsibilities and the limitations of authority of ENGINEER as OWNER's representative during construction are set forth in the Contract Documents and will not be changed without written consent of OWNER and ENGINEER. 9.02 Visits to Site A. ENGINEER will make visits to the Site at intervals appropriate to the various stages of construction as ENGINEER deems necessary in order to observe as an experienced and qualified design professional the progress that has been made and the quality of the various aspects of CONTRACTOR's executed Work. Based on information obtained during such visits and observations, ENGINEER, for the benefit of OWNER, will determine, in general, if the Work is proceeding in accordance with the Contract Documents. ENGINEER will not be required to make exhaustive or continuous inspections on the Site to check the quality or quantity of the Work. ENGINEER's efforts will be directed toward providing for OWNER a greater degree of confidence that the completed Work will conform generally to the Contract Documents. On the basis of such visits and observations, ENGINEER will keep OWNER informed of the progress of the Work and will endeavor to guard OWNER against defective Work. B.

When all the Work is performed on the basis of cost-plus, the costs of premiums for all Bonds and insurance CONTRACTOR is required by the Contract Documents to purchase and maintain. B. Costs Excluded: The term Cost of the Work shall not include any of the following items: 1. Payroll costs and other compensation of CONTRACTOR's officers, executives, principals (of partnerships and sole proprietorships), general manag- ers, engineers, architects, estimators, attorneys, audi- tors, accountants, purchasing and contracting agents, expediters, timekeepers, clerks, and other personnel employed by CONTRACTOR, whether at the Site or in CONTRACTOR's principal or branch office for general administration of the Work and not specifically included in the agreed upon schedule of job classifications referred to in paragraph 11.01.A.1 or specifically covered by paragraph 11.01. A.4, all of which are to be 00700-31 ARTICLE 12 - CHANGE OF CONTRACT PRICE; CHANGE OF CONTRACT TIMES 12.01 Change of Contract Price A. The Contract Price may only be changed by a Change Order or by a Written Amendment. Any Claim for an adjustment in the Contract Price shall be based on written notice submitted by the party making the Claim to the ENGINEER and the other party to the Contract in accor- dance with the provisions of paragraph 10.05. B. The value of any Work covered by a Change Order or of any Claim for an adjustment in the Contract Price will be determined as follows: 1. where the Work involved is covered by unit prices contained in the Contract Documents, by applica- tion of such unit prices to the quantities of the items involved (subject to the provisions of paragraph 11.03 ); or 2. where the Work involved is not covered by unit prices contained in the Contract Documents, by a mutually agreed lump sum (which may include an allowance for overhead and profit not necessarily in accordance with paragraph 12.01.C.2); or 3. where the Work involved is not covered by unit prices contained in the Contract Documents and agree- ment to a lump sum is not reached under paragraph 12.01.B.2, on the basis of the Cost of the Work (determined as provided in paragraph 11.01) plus a CONTRACTOR's fee for overhead and profit (deter- mined as provided in paragraph 12.01.C). C. COITRACTOR's Fee: The CONTRACTOR's fee for overhead and profit shall be determined as follows: 1. a mutually acceptable fixed fee; or 2. if a fixed fee is not agreed upon, then a fee based on the following percentages of the various portions of the Cost of the Work: a. for costs incurred under paragraphs 11.01.A.1 and 11.O1.A.2, the CONTRACTOR's fee shall be 15 percent; b. for costs incurred under paragraph 11.01.A.3, the CONTRACTOR's fee shall be five percent; c. where one or more tiers of subcontracts are on the basis of Cost of the Work plus a fee and no fixed fee is agreed upon, the intent of paragraph 12.01. C .2. a is that the Subcontractor who actually performs the Work, at whatever tier, will be paid a fee of 15 percent of the costs incurred by such Subcontractor under paragraphs 11.01.A.1 and 11.01.A.2 and that any higher tier Subcontractor and CONTRACTOR will each be paid a fee of five percent of the amount paid to the next lower tier Subcontractor; d. no fee shall be payable on the basis of costs itemized under paragraphs 11.01.A.4, 11.01.A.5, and 11.01.B; e. the amount of credit to be allowed by CONTRACTOR to OWNER for any change which results in a net decrease in cost will be the amount of the actual net decrease in cost plus a deduction in CONTRACTOR's fee by an amount equal to five percent of such net decrease; and f. when both additions and credits are in- volved in any one change, the adjustment in CONTRACTOR's fee shall be computed on the basis of the net change in accordance with para- graphs 12.01. C . 2 . a through 12.01. C . 2 . e, inclu- sive. 12.02 Change of Contract Times A. The Contract Times (or Milestones) may only be changed by a Change Order or by a Written Amendment. Any Claim for an adjustment in the Contract Times (or Milestones) shall be based on written notice submitted by the party making the claim to the ENGINEER and the other party to the Contract in accordance with the provisions of paragraph 10.05. B. Any adjustment of the Contract Times (or Milestones) covered by a Change Order or of any Claim for an adjustment in the Contract Times (or Milestones) will be determined in accordance with the provisions of this Article 12. 12.03 Delays Beyond CONTRACTOR's Control A. Where CONTRACTOR is prevented from completing any part of the Work within the Contract Times (or Milestones) due to delay beyond the control of CONTRACTOR, the Contract Times (or Milestones) will be extended in an amount equal to the time lost due to such delay if a Claim is made therefor as provided in paragraph 12.02. A. Delays beyond the control of CONTRACTOR shall include, but not be limited to, acts or neglect by OWNER, acts or neglect of utility owners or other contractors performing other work as contemplated by 00700 - 33 E. If any Work (or the work of others) that is to be inspected, tested, or approved is covered by CONTRACTOR without written concurrence of ENGINEER, it must, if requested by ENGINEER, be uncovered for observation. F. Uncovering Work as provided in paragraph 13.03 . E shall be at CONTRACTOR's expense unless CON- TRACTOR has given ENGINEER timely notice of CONTRACTOR's intention to cover the same and ENGI- NEER has not acted with reasonable promptness in response to such notice. 13.04 Uncovering Work A. If any Work is covered contrary to the written request of ENGINEER, it must, if requested by ENGINEER, be uncovered for ENGINEER's observation and replaced at CONTRACTOR's expense. B. If ENGINEER considers it necessary or advisable that covered Work be observed by ENGINEER or inspected or tested by others, CONTRACTOR, at ENGINEER's request, shall uncover, expose, or otherwise make available for observation, inspection, or testing as ENGINEER may require, that portion of the Work in question, furnishing all necessary labor, material, and equipment. If it is found that such Work is defective, CONTRACTOR shall pay all Claims, costs, losses, and damages (including but not limited to allfees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such uncovering, exposure, observation, inspection, and testing, and of satisfactory replacement or reconstruction (including but not limited to all costs of repair or replacement of work of others); and OWNER shall be entitled to an appropriate decrease in the Contract Price. If the parties are unable to agree as to the amount thereof, OWNER may make a Claim therefor as provided in paragraph 10.05. If, however, such Work is not found to be defective, CONTRACTOR shall be allowed an increase in the Contract Price or an extension of the Contract Times (or Milestones), or both, directly attribut- able to such uncovering, exposure, observation, inspection, testing, replacement, and reconstruction. If the parties are unable to agree as to the amount or extent thereof, CONTRACTOR may make a Claim therefor as provided in paragraph 10.05. 13.05 OWNER May Stop the Work A. If the Work is defective, or CONTRACTOR fails to supply sufficient skilled workers or suitable materials or equipment, or fails to perform the Work in such a way that the completed Work will conform to the Contract Documents, OWNER may order CONTRACTOR to stop the Work, or any portion thereof, until the cause for such order has been eliminated; however, this right of OWNER to stop the Work shall not give rise to any duty on the part of OWNER to exercise this right for the benefit of CONTRACTOR, any Subcontractor, any Supplier, any other individual or entity, or any surety for, or employee or agent of any of them. 13.06 Correction or Removal of Defective Work A. CONTRACTOR shall correct all defective Work, whether or not fabricated, installed, or completed, or, if the Work has been rejected by ENGINEER, remove it from the Project and replace it with Work that is not defective. CONTRACTOR shall pay all Claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such correction or removal (including but not limited to all costs of repair or replacement of work of others) . 13.07 Correction Period A. If within one year after the date of Substantial Completion or such longer period of time as may be prescribed by Laws or Regulations or by the terms of any applicable special guarantee required by the Contract Documents or by any specific provision of the Contract Documents, any Work is found to be defective, or if the repair of any damages to the land or areas made available for CONTRACTOR's use by OWNER or permitted by Laws and Regulations as contemplated in paragraph 6.11. A is found to be defective, CONTRACTOR shall promptly, without cost to OWNER and in accordance with OWNER's written instructions: (i) repair such defective land or areas, or (ii) correct such defective Work or, if the defective Work has been rejected by OWNER, remove it from the Project and replace it with Work that is not defective, and (iii) satisfac- torily correct or repair or remove and replace any damage to other Work, to the work of others or other land or areas resulting therefrom. If CONTRACTOR does not promptly comply with the terms of such instructions, or in an emergency where delay would cause serious risk of loss or damage, OWNER may have the defective Work corrected or repaired or may have the rejected Work removed and replaced, and all Claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such correction or repair or such removal and replacement (including but not limited to all costs of repair or replacement of work of others) will be paid by CONTRACTOR. B. In special circumstances where a particular item of equipment is placed in continuous service before Substantial Completion of all the Work, the correction period for that 00700 - 35 14.02 Progress Payments a. the Work has progressed to the point indicated; A. Applications for Payments 1. At least 20 days before the date established for each progress payment (but not more often than once a month), CONTRACTOR shall submit to ENGINEER for review an Application for Payment filled out and signed by CONTRACTOR covering the Work completed as of the date of the Application and accompanied by such supporting documentation as is required by the Contract Documents. If payment is requested on the basis of materials and equipment not incorporated in the Work but delivered and suitably stored at the Site or at another location agreed to in writing, the Application for Payment shall also be accompanied by a bill of sale, invoice, or other docu- mentation warranting that OWNER has received the materials and equipment free and clear of all Liens and evidence that the materials and equipment are covered by appropriate property insurance or other arrangements to protect OWNER's interest therein, all of which must be satisfactory to OWNER. 2. Beginning with the second Application for Payment, each Application shall include an affidavit of CONTRACTOR stating that all previous progress payments received on account of the Work have been applied on account to discharge CONTRACTOR's legitimate obligations associated with prior Applications for Payment. 3. The amount of retainage with respect to pro- gress payments will be as stipulated in the Agreement. B . Review of Applications 1. ENGINEER will, within 10 days after receipt of each Application for Payment, either indicate in writing a recommendation of payment and present the Application to OWNER or return the Application to CONTRACTOR indicating in writing ENGINEER's reasons for refusing to recommend payment. In the latter case, CONTRACTOR may make the necessary corrections and resubmit the Application. 2. ENGINEER's recommendation of any payment requested in an Application for Payment will constitute a representation by ENGINEER to OWNER, based on ENGINEER's observations on the Site of the executed Work as an experienced and qualified design profession- al and on ENGINEER' s review of the Application for Payment and the accompanying data and schedules, that to the best of ENGINEER's knowledge, information and belief: 00700 - 37 b. the quality of the Work is generally in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning whole prior to or upon Substantial Completion, to the results of any subsequent tests called for in the Contract Documents, to a final determination of quantities and classifications for Unit Price Work under paragraph 9.08, and to any other qualifications stated in the recommendation); and c. the conditions precedent to CONTRACTOR's being entitled to such payment appear to have been fulfilled in so far as it is ENGINEER's responsibility to observe the Work. 3. By recommending any such payment ENGI- NEER will not thereby be deemed to have represented that: (i) inspections made to check the quality or the quantity of the Work as it has been performed have been exhaustive, extended to every aspect of the Work in progress, or involved detailed inspections of the Work beyond the responsibilities specifically assigned to ENGINEER in the Contract Documents; or (ii) that there may not be other matters or issues between the parties that might entitle CONTRACTOR to be paid additionally by OWNER or entitle OWNER to withhold payment to CONTRACTOR. 4. Neither ENGINEER's review of CONTRACTOR's Work for the purposes of recom- mending payments nor ENGINEER's recommendation of any payment, including final payment, will impose responsibility on ENGINEER to supervise, direct, or control the Work or for the means, methods, techniques, sequences, or procedures of construction, or the safety precautions and programs incident thereto, or for CON- TRACTOR's failure to comply with Laws and Regu- lations applicable to CONTRACTOR's performance of the Work. Additionally, said review or recommendation will not impose responsibility on ENGINEER to make any examination to ascertain how or for what purposes CONTRACTOR has used the moneys paid on account of the Contract Price, or to determine that title to any of the Work, materials, or equipment has passed to OWNER free and clear of any Liens. 5. ENGINEER may refuse to recommend the whole or any part of any payment if, in ENGINEER's opinion, it would be incorrect to make the representa- tions to OWNER referred to in paragraph 14.02.B.2. ENGINEER may also refuse to recommend any such payment or, because of subsequently discovered evidence or the results of subsequent inspections or tests, ties pending fmal payment between OWNER and CONTRACTOR with respect to security, operation, safety, and protection of the Work, maintenance, heat, utilities, insurance, and warranties and guarantees. Unless OWNER and CONTRACTOR agree otherwise in writing and so inform ENGINEER in writing prior to ENGINEER's issuing the definitive certificate of Substantial Completion, ENGINEER's aforesaid recommendation will be binding on OWNER and CONTRACTOR until fmal payment. B. OWNER shall have the right to exclude CONTRACTOR from the Site after the date of Substantial Completion, but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. 14.05 Partial Utilization A. Use by OWNER at OWNER's option of any substantially completed part of the Work which has specifically been identified in the Contract Documents, or which OWNER, ENGINEER, and CONTRACTOR agree constitutes a separately functioning and usable part of the Work that can be used by OWNER for its intended purpose without significant interference with CONTRACTOR's performance of the remainder of the Work, may be accomplished prior to Substantial Completion of all the Work subject to the following conditions. 1. OWNER at any time may request CON- TRACTOR in writing to permit OWNER to use any such part of the Work which OWNER believes to be ready for its intended use and substantially complete. If CONTRACTOR agrees that such part of the Work is substantially complete, CONTRACTOR will certify to OWNER and ENGINEER that such part of the Work is substantially complete and request ENGINEER to issue a certificate of Substantial Completion for that part of the Work. CONTRACTOR at any time may notify OWNER and ENGINEER in writing that CONTRACTOR considers any such part of the Work ready for its intended use and substantially complete and request ENGINEER to issue a certificate of Substantial Completion for that part of the Work. Within a reasonable time after either such request, OWNER, CONTRACTOR, and ENGINEER shall make an inspection of that part of the Work to determine its status of completion. If ENGINEER does not consider that part of the Work to be substantially complete, ENGINEER will notify OWNER and CONTRACTOR in writing giving the reasons therefor. If ENGINEER considers that part of the Work to be substantially complete, the provisions of paragraph 14.04 will apply with respect to certification of Substantial Completion of that part of the Work and the division of responsibility in respect thereof and access thereto. 2. No occupancy or separate operation of part of the Work may occur prior to compliance with the requirements of paragraph 5.10 regarding property insurance. 14.06 Final Inspection A. Upon written notice from CONTRACTOR that the entire Work or an agreed portion thereof is complete, ENGINEER will promptly make a fmal inspection with OWNER and CONTRACTOR and will notify CON- TRACTOR in writing of all particulars in which this inspection reveals that the Work is incomplete or defective. CONTRACTOR shall immediately take such measures as are necessary to complete such Work or remedy such deficiencies. 14.07 Final Payment A. Application for Payment 1. After CONTRACTOR has, in the opinion of ENGINEER, satisfactorily completed all corrections identified during the final inspection and has delivered, in accordance with the Contract Documents, all main- tenance and operating instructions, schedules, guaran- tees, Bonds, certificates or other evidence of insurance certificates of inspection, marked -up record documents (as provided in paragraph 6.12), and other documents, CONTRACTOR may make application for fmal payment following the procedure for progress payments. 2. The . final Application for Payment shall be accompanied (except as previously delivered) by: (i) all documentation called for in the Contract Documents, including but not limited to the evidence of insurance required by subparagraph 5.04. B .7; (ii) consent of the surety, if any, to final payment; and (iii) complete and legally effective releases or waivers (satisfactory to OWNER) of all Lien rights arising out of or Liens filed in connection with the Work. 3. In lieu of the releases or waivers of Liens specified in paragraph 14.07.A.2 and as approved by OWNER, CONTRACTOR may furnish receipts or releases in full and an affidavit of CONTRACTOR that: (i) the releases and receipts include all labor, services, material, and equipment for which a Lien could be filed; and (ii) all payrolls, material and equipment bills, and other indebtedness connected with the Work for which OWNER or OWNER's property might in any way be responsible have been paid or otherwise satisfied. If any Subcontractor or Supplier fails to furnish such a release or receipt in full, CONTRACTOR may furnish a Bond or other collateral satisfactory to OWNER to indemnify OWNER against any Lien. 00700 - 39 the services of CONTRACTOR, exclude CONTRACTOR from the Site, and take possession of the Work and of all CONTRACTOR's tools, appliances, construction equipment, and machinery at the Site, and use the same to the full extent they could be used by CONTRACTOR (without liability to CONTRACTOR for trespass or conversion), incorporate in the Work all materials and equipment stored at the Site or for which OWNER has paid CONTRACTOR but which are stored elsewhere, and finish the Work as OWNER may deem expedient. In such case, CONTRACTOR shall not be entitled to receive any further payment until the Work is finished. If the unpaid balance of the Contract Price exceeds all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) sustained by OWNER arising out of or relating to completing the Work, such excess will be paid to CONTRACTOR. If such claims, costs, losses, and damages exceed such unpaid balance, CONTRACTOR shall pay the difference to OWNER. Such claims, costs, losses, and damages incurred by OWNER will be reviewed by ENGINEER as to their reasonableness and, when so approved by ENGINEER, incorporated in a Change Order. When exercising any rights or remedies under this paragraph OWNER shall not be required to obtain the lowest price for the Work performed. C. Where CONTRACTOR's services have been so terminated by OWNER, the termination will not affect any rights or remedies of OWNER against CONTRACTOR then existing or which may thereafter accrue. Any retention or payment of moneys due CONTRACTOR by OWNER will not release CONTRACTOR from liability. 15.03 OWNER May Terminate For Convenience A. Upon seven days written notice to CONTRACTOR and ENGINEER, OWNER may, without cause and without prejudice to any other right or remedy of OWNER, elect to terminate the Contract. In such case, CONTRACTOR shall be paid (without duplication of any items) : 1. for completed and acceptable Work executed in accordance with the Contract Documents prior to the effective date of termination, including fair and reasonable sums for overhead and profit on such Work; 2. for expenses sustained prior to the effective date of termination in performing services and furnishing labor, materials, or equipment as required by the Contract Documents in connection with uncompleted Work, plus fair and reasonable sums for overhead and profit on such expenses; 3. for all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) incurred in settlement of terminated contracts with Subcontractors, Suppliers, and others; and 4. for reasonable expenses directly attributable to termination. B. CONTRACTOR shall not be paid on account of loss of anticipated profits or revenue or other economic loss arising out of or resulting from such termination. 15.04 CONTRACTOR May Stop Work or Terminate A. If, through no act or fault of CONTRACTOR, the Work is suspended for more than 90 consecutive days by OWNER or under an order of court or other public authority, or ENGINEER fails to act on any Application for Payment within 30 days after it is submitted, or OWNER fails for 30 days to pay CONTRACTOR any sum fmally determined to be due, then CONTRACTOR may, upon seven days written notice to OWNER and ENGINEER, and provided OWNER or ENGINEER do not remedy such suspension or failure within that time, terminate the Contract and recover from OWNER payment on the same terms as provided in paragraph 15.03. In lieu of terminating the Contract and without prejudice to any other right or remedy, if ENGI- NEER has failed to act on an Application for Payment within 30 days after it is submitted, or OWNER has failed for 30 days to pay CONTRACTOR any sum fmally determined to be due, CONTRACTOR may, seven days after written notice to OWNER and ENGINEER, stop the Work until payment is made of all such amounts due CONTRACTOR, including interest thereon. The provisions of this paragraph 15.04 are not intended to preclude CONTRACTOR from making ' a Claim under paragraph 10.05 for an adjustment in Contract Price or Contract Times or otherwise for expenses or damage directly attributable to CONTRACTOR's stopping the Work as permitted by this paragraph. ARTICLE 16 - DISPUTE RESOLUTION 16.01 Methods and Procedures A. Dispute resolution methods and procedures, if any, shall be as set forth in the Supplementary Conditions. If no method and procedure has been set forth, and subject to the provisions of paragraphs 9.09 and 10.05, OWNER and CONTRACTOR may exercise such rights or remedies as either may otherwise have under the Contract Documents or by Laws or Regulations in respect of any dispute. 00700-41 SUPPLEMENTARY CONDITIONS OF THE CONTRACT These supplementary conditions amend the general conditions of the project by addition or deletion of certain provisions.

Keep chutes troughs and pipe clean and free from coatings of hardened concrete. Use of chutes in excess of 35-foot (35') total length, by specific authorization only. c. Depositing. Limit free fall of concrete to four (4) feet. Use tremies for placing concrete in walls, and similar placement. Do not deposit large quantities of concrete at one point in forms such that it requires running or working it along forms. Do not jar forms after concrete has taken initial set, or place any strain on projecting reinforcement or anchor bolts. Make tremies in sections, or provide in several lengths, so that outlet may be adjusted to proper heights during placing operations. Place concrete in continuous horizontal layers approximately 12-inch (12") thickness. Place each layer while layer below is still soft, and unless otherwise specified, let not more than one (1) hour elapse between placing of successive layers in continuous placement. d. Consolidation. Compact each layer of concrete with concrete spading implements and mechanical vibrators of approved type Use vibrators of type which operates by attachment to forms only when immersion type vibrators cannot be used. Apply vibrators to concrete immediately after depositing, and move through layer of concrete just placed and several inches into plastic layer below. Do not penetrate or disturb layers previously placed which have partially set, and do not use vibrators to aid flow of concrete laterally. 3.8 CURING a. General.

Use graduated scales or dial indicator showing increments of five (5) pounds or less. (3) Use scales accurate within four (4) pounds per 1,000 pounds net load in the hopper. c. Mixer. (1) A capacity of not less than 14-S mixer, as rated by Mixer Manufacturers Bureau of Associated General Contractors, is required. Provide a speed regulator to hold a mixer to the normal speed of revolution. Equip the mixer with an automatic timer and lock for the discharging device to prevent discharge until all materials have been mixed together for the minimum time required. The time and lock must operate independently of the dnim Also provide a bell to indicate completion of a mixing time. The bell must be plainly audible to a distance of 50 feet from the mixer. (2) Equip the mixer with an accurate device to measure water within one percent (1%) of the total amount required. Construct the measuring drum with an opening to atmospheric pressure when the measured amount of water is inside. Place and construct the drum so that a single batch of water can be discharged into a calibrated tank or a weighing device attached to the mixer, without seriously delaying paving operations. Check the operation of this water measuring device daily. d. Batch Truck: Batch trucks, for the transportation of measured materials from the batching plant to the mixer, must be covered tight to prevent excessive evaporation or any loss of materials. 02614-5 2.4 MIXING a.

Equip truck mixers with water tank and measuring devices which permit positive measurement of mixing water. When aggregate contains more than six percent (6%) water, place the concrete within one hour after the introduction of water. When aggregate contains from three percent (3%) to six percent (6%) water, place concrete within one hour after the introduction of cement. Transit -mix concrete must conform to other applicable requirements of this section. 3.0 EXECUTION 3.1 WEATHER CONDITIONS Place concrete only when the air temperature is above 400F and rising. Place no concrete if the temperature is below 50oF and falling. Maintain the temperature of the air surrounding the concrete at 50oF for not less than five (5) days. The Contractor is responsible for the quality and strength of concrete placed under any weather conditions. 3.2 EQUIPMENT Equipment for preparing subgrade and for finishing and compacting must be in good working order and be approved before commencing work. a. Subgrade Planer and Template. (1) Use a subgrade planer with adjustable cutting blades to trim the subgrade to the exact section shown on the drawing. Select a planer with visible rollers which ride on the form. The planer frame must have sufficient weight so that it will remain on the form at all times and have such strength and rigidity that, under tests made by changing the support from wheels to center, the planer will not develop deflection of more than 1/8-inch (1/8'). Tractors used to pull the planer must not produce ruts or indentations in the subgrade. When the slip form method of paving is used, operate the subgrade planer on a prepared track grade or have it controlled by an electronic sensor system operated from a string line that establishes the horizontal alignment and elevation of the subbase. (2) Provide a template for checking the contour of the subgrade. The template must be long enough to rest upon side forms and have such strength and rigidity that under tests made by changing the support to the center, the template will not show deflection of more than 1/8-inch (1/8' ). Fit the template with accurately adjustable rods projecting downward at one foot (1) intervals Adjust these rods to gage the cross sections of the slab bottom when the template is resting on the side forms. b. Machine Finisher. Provide a power -driven transverse finishing machine designed and operated to strike off and consolidate the concrete. Select a machine with two (2) screeds accurately adjusted to the crown of the pavement 02614-6 (3) and with a frame equipped to ride on the form. Use a finishing machine with rubber tires if it operates on concrete pavement. Hand Finishing. (1) Provide a mechanical strike and tamping template the width of pavement to be finished. Shape the template to the pavement section. (2) Also provide floats of approved design. Provide two (2) bridges for finishing expansion and dummy joints and necessary edging and finishing tools to complete the pavement slab. d. Burlap Drag for Finishing Slab. Furnish four (4) plies of 10 ounce burlap material fastened to a bridge to form a continuous strip of burlap the full width of the pavement. The three-foot (3') width of burlap material must be in contact with the pavement surface. Keep the burlap drags clean and free of encrusted mortar e. Vibrators. Furnish mechanically operated synchronized vibrators mounted on a tamping bar which rides on the forms. Also employ approved hand manipulated mechanical vibrators. Furnish vibrators with a frequency of vibration providing the maximum consolidation of concrete without segregation. f. Traveling Form Paver. A traveling form paver of approved design may be used in lieu of construction methods employing forms, consolidating, finishing and floating equipment. If a traveling form paver is used, all requirements of this specification for subgrade pavement tolerances, pavement depth, alignments, consolidation, finishing and workmanship must be met in full If a traveling form paver proves inadequate in the opinion of the Engineer, in providing a pavement which meets the drawings and specification in all respects, its use will be immediately discontinued when so ordered by the Engineer and conventional methods will be used. (1) Equip traveling paver with a longitudinal transangular finishing float adjustable to crown and grade. The float must be long enough to extend across the pavement practically to the side forms or the edge of the slab. (2) Prior to beginning paving operations, insure that a continuous deposit of concrete can be made at the paver to minimize starting and stopping. Pave by conventional means those locations inaccessible to a traveling paver, or having horizontal or vertical curvature that a traveling paver cannot negotiate. Do not place reinforcing steel mechanically. Where the plans require tie bars to be installed for adjacent paving, securely tie and support the bars to prevent displacement. Alternatively, tie bars may be installed with an approved mechanical bar insert mounted on a traveling -form paver. Replace any pavement in which tie bars assume a final position other than that shown on the drawing, unless corrective alternates are authorized in writing and carried out to the satisfaction of the Engineer. 02614-7 3.3 SUBGRADE Properly prepare shape and compact each section of subgrade before placing forms, steel or concrete. After forms have been set to proper grade and alignment, use a subgrade planer to shape the subgrade to its final cross section. Check the contour of the subgrade with the template. 3.4 FORMS a. Side Forms. Use metal or wood forms of approved shape and section A form as deep as the pavement edge thickness is preferred. Forms with depth up to one -inch (1") greater or less than pavement thickness may be used. Forms with less depth than pavement thickness will be brought to required depth by securely attaching wooden planks of approved section and size to the bottom of the form. Use a form section at least 10 feet in length and staked in position with at least three (3) pins. Forms must have adequate strength to withstand machine loads without visible springing or settlement. Use forms free from warps bends and kinks and sufficiently true to provide a straight edge on the concrete Test the top of each form section with a straight edge and verify that it conforms with requirements for the surface of complete pavement. Use flexible or curbed forms of wood or metal to set the proper radius on curves of 100 feet radius or less. b. Form Setting. (1) Rest forms directly on subgrade. Do not shim with pebbles or dirt. Remove subgrade that will not support the loaded form. Replace and compact subgrade to required density. Accurately set forms to required grade and alignment and, during the entire operation of placing, compacting and fmishing of concrete, do not deviate from this grade and alignment more than 1/8-inch (1/8") to 10 feet in length. Do not remove forms for at least 24 hours after the completion of finishing operations. Provide a supply of forms that will be adequate to comply with this requirement and for orderly and continuous placing of concrete. Set the forms and check the grade for at least 130 feet ahead of the mixer. (2) Adjacent slabs may be used instead of the forms, provided that the concrete is well protected from possible damage by finishing equipment. These adjacent slabs must not be used for forms until the concrete has aged at least seven (7) days. For short radius curves, forms less than 10 feet in length or curved forms may be used. For curb returns at street intersections and driveways, wood forms of good grade and quality may be used. Do not use any material which, in the opinion of the Engineer is unsuitable for forms. 3.5 REINFORCING STEEL AND JOINT ASSEMBLIES a. Accurately place reinforcing steel and joint assemblies and position them securely in accord with details shown. Wire reinforcing bars securely together at intersections and splices. Bars and coatings must be free of rust, dirt or other foreign matter when the concrete is installed. b. Place pavement joint assemblies at required locations and elevations and rigidly secure all parts in required positions Install dowel bars accurately in joint assemblies as shown, each parallel to the pavement surface and to the center line of the pavement and rigidly secure in the required position to prevent displacement during placing and finishing of concrete Accurately cut header boards, joint filler and other material used for forming joints to receive each dowel bar. Place all reinforcing steel and secure to chairs. 02614-8 3.6 PLACING a. Batches not placed as specified within 30 minutes after water or cement has been added will be rejected Fine aggregate containing more than six percent (6%) moisture and coarse aggregate containing more than three percent (3%) moisture will likewise be rejected. b. Deposit concrete rapidly and continuously on subgrade or subbase in successive batches. Distribute concrete to the required depth and for entire width of the pour by shoveling or by other approved methods Do not use rakes in handling concrete. At the end of the day or in case of unavoidable interruption of more than 30 minutes, place a transverse construction joint at the point of stopping work, provided that the section on which work has been suspended is not less than 10 feet from the preceding joint. Sections less than 10 feet along must be removed and replaced. c. Take special care in placing and spading concrete against forms and at longitudinal and transverse joints to prevent honeycombing. Voids in the edge of the finished pavement will be cause for rejection. 3.7 COMPACTING a. Consolidate the concrete using an approved mechanical vibratory unit designed to vibrate concrete internally Extend a vibratory unit across the pavement, not quite touching the side forms. Equip the unit with synchronized vibrators. Space individual vibrators at close enough intervals to vibrate and consolidate the entire width of the pavement uniformly Mount mechanical vibrators to avoid contact with forms, reinforcement, transverse or longitudinal joints. b. Furnish enough hand -manipulated mechanical vibrators for proper consolidation of concrete along forms, at joints and in areas not covered by mechanically controlled vibrators. 3.8 FINISHING a. Finish concrete pavement by power -driven transverse finishing machines or by hand finishing methods. Re - tempering by water sprinkling before finishing is not acceptable. (1) Use the transverse finishing machine to make at least two (2) trips over each area. Make the last trip over a given area a continuous run of not less than 40 feet. After transverse screeding, use a hand operated longitudinal float to test and level the surface to the required grade. (2) Hand finish with a mechanical strike and tamping template as wide as the pavement to be finished. Shape the template to the pavement section. Move the strike template forward in the direction of the work, maintaining a slight excess of material in front of the cutting edge. Make at least two (2) trips over each area. Screed the pavement surface to the required section Work the screed with a combined transverse and longitudinal motion in the direction work is progressing. Maintain the screed in contact with the forms. Use a longitudinal float to level the surface. b. On narrow strips and transitions, finish concrete pavement by hand. Thoroughly work concrete around reinforcement and embedded fixtures. Strike -off concrete with a strike -off screed. Move the strike -off screed forward with combined transverse and longitudinal motion in direction work is progressing, maintaining the screed in contact with the forms, and maintaining a slight excess of materials in front of the cutting edge. Tamp the concrete with a tamping template. Use a longitudinal float to level the surface. c. After completion of the straight edge operation, make the first pass of a burlap drag as soon as construction operations permit and before the water sheen has disappeared from the surface Follow this by as many passes as required to produce the desired texture depth. Permit no unnecessary delays between passes Keep the drag wet, clean and free from encrusted mortar during use. 02614-9 3.9 SURFACE TESTS Test the entire surface before the initial set and correct irregularities or undulations. Bring surface within requirements of the following test and then finish. Place an approved 10-foot (10') straight edge parallel to the center of the roadway to bridge any depressions and touch all high spots. Do not permit ordinates measured from the face of the straight edge to the surface of the pavement to exceed 1/16-inch (1/16') per foot from the nearest point of contact. In no case permit the maximum ordinate to a 10-foot (10') straight edge to exceed 1/8-inch (1/8"). 3.10 JOINTS a. Placement. Place joints of the types shown on drawings at required locations and at spacings shown. b. Construction Joints. Place a transverse construction joint wherever concrete placement must be stopped for more than 30 minutes. Place longitudinal construction joints at interior edges of pavement lanes where required. Work the concrete well against the bulkhead. The key -way on the longitudinal construction joint may be omitted when a traveling form paver is used, and when No. 5 deformed tie bars, 30 inches long and space inches on centers are used. c. Expansion Joints. Place expansion joints at radius points of curb returns for cross street intersections, or as shown. Use no boards shorter than six (6) feet. When pavement is 24 feet or narrower, use not more than two (2) lengths of board. Secure pieces to form a straight joint. Shape board filler accurately to the cross section of the concrete slab. Use premolded joint filler, accurately shaped, in curb section. Use load transmission devices of the type and size shown. Use a joint sealing compound as required. d. Contraction Joints. Make contraction joints straight and transverse to the center line of the pavement with a deformed metal strip. Place them at 20-foot (20') spacings between expansion Joints or halfway between expansion joints less than 40-foot (40') spacing. Adequately stake metal strip in place to prevent lateral movement of the metal strip while the concrete is being placed. Use joint sealing compound as required. e. Longitudinal Weakened Plane Joints. Make a longitudinal weakened plane joint with a deformed metal strip. Adequately stake the metal step n place to prevent lateral movement of the metal strip while the concrete is being placed. Use joint sealing compound as required. 3.11 MEMBRANE CURING a. After the concrete surface has been finally finished and the surplus water sheen has disappeared, seal the surface with single uniform coating of an approved curing compound. Apply the compound at the rate of coverage recommended by the manufacturer and as directed by Engineer but not less than one (1) gallon per 180 square feet of surface area. Control and check the rate of application. b. Thoroughly agitate the compound during use and apply by means of approved mechanical power pressure sprayers equipped with satisfactory atomizing nozzles. For application on small miscellaneous items, hand powered spray equipment may be used. For all spraying equipment, provide means to prevent loss of compound between the nozzle and the concrete surface while spraying. c. Thoroughly moisten the surface just before applying the curing compound. Where discontinuities, pin holes or other defects show, or where ram has fallen, immediately apply an additional coat of compound to the newly coated surface before the film has dried sufficiently to resist damage. Apply the added coat at the same rate of coverage as specified. 3.12 JOINT SEALING 02614-10 a.

Compartments of ample size constructed so that materials will be kept separate under all working conditions are required. (2) Weighing of Materials. Aggregates may be weighed in separate weigh batchers with individual scales. Weigh bulk cement on a separate scale in a separate weigh batcher. Observe the following limits of accuracy when weighing or measuring materials. (3) Materials Percent Accuracy Cement 1 Water Aggregates 2 Admixture 3 Water Meter or Batcher. Provide a suitable measuring device capable of measuring mixing water within the specified accuracy for each batch. Note the number of gallons of water as batched on printed batching tickets. (4) Moisture Control. Provide a moisture meter to measure the amount of free water in fine aggregates within 0.3 of a percent. Compensate for varying moisture contents of fine aggregates and change batch weights of materials if necessary before batching 03300-4 (3) (7) (5) Scales. Provide adequate facilities for accurate measurement and control of each material entering each batch of concrete. Accuracy of weighing equipment must conform to applicable requirements of ASTM and NRMCA for such equipment. (6) Recorders or Printers. Provide recorders/printers to produce tickets. Each ticket will provide a printed record of weights for cement as batched and for separate aggregates as batched individually. Use the type of indicator that returns for zero punch or to zero after a batch is discharged Clearly indicate by stamped letters or numbers the difference between aggregates and cement as batched Show the time of day stamped or printed at intervals of not more than six (6) minutes. Deliver recorded ticket copies with concrete. The testing agency will keep one (1) copy. Protection. Protect weighing, indicating, recording or printing, and control equipment against exposure to dust and weather b. Transit Mix Truck Re uirements (1) batching plant. Clean each transit mix truck drum and reverse drum rotation before the truck proceeds under the (2) Keep the water tank valve on each transit truck locked at all times that the truck is in use. Any addition of water must be directed by the Engineer Added water must be incorporated by additional mixing of at least 35 revolutions or two (2) minutes. Equip each transit -mix truck with a continuous, nonreversible, revolution counter showing the number of revolutions at mixing speeds. c. Batch Mixin at t Site (1) Mix concrete in a batch mixer conforming to requirements of the Mixer Manufacturers' Bureau of the Associated General Contractors of America. Use a mixer equipped with a suitable charging hopper, water storage tank and water measuring devices It must be capable of thoroughly mixing aggregates, cement and water into a uniform mass within the specified mixing time, and of discharging the mix without segregation. Operate the mixer according to the rated capacity and recommended revolutions per minute printed on the manufacturer's rating plate (2) Charge the batch into the mixer so that some water will enter in advance of cement and aggregates. Keep water running until 1/4 of specified mixing time has elapsed. Provide controls to prevent discharging until the required mixing time has elapsed. When concrete of normal weight is specified provide controls to prevent the addition of water during mixing. Discharge the entire batch before the mixer is recharged. (3) Mix each batch of two (2) cubic yards or less for not less than one (1) minute and 30 seconds. Increase mixing time 15 seconds for each additional cubic yard or fraction of a yard. (4) Keep the mixer clean. Replace pick-up and throw -over blades in the drum when they have lost 10 percent (I0%) of original depth. d. Admixtures (1) Charge air-entraming and chemical admixtures into the mixer as a solution using an automatic dispenser or similar metering device. Measure admixture to an accuracy within ±3 percent (3%). Do not use admixtures in powdered form. 03300-5 (2) Two (2) or more admixtures may be used in the same concrete, provided that the admixtures in combination retain full efficiency and have no deleterious effect on the concrete or on the properties of each other. Inject the admixtures separately during the batching sequence. (3) Add retarding admixtures as soon as practicable after the addition of cement. e. Temperature Control (1) When the mean temperature falls below 40oF, keep the admixed temperature above 550F to maintain concrete above the minimum placing temperature. (2) If water or aggregates have been heated, combine water with aggregate in the mixer before cement is added. Do not add cement to the mixtures of water and aggregate when the temperature of the mixture is greater than 1000F. (3) In hot weather, cool ingredients before mixing to maintaintemperature of the concrete below the maximum placing temperature. If necessary, substitute well -crushed ice for all or part of the mixing water. 3.0 EXECUTION 3.1 PREPARATION a. Coordination Mix concrete only m quantities for immediate use. Discard concrete which has set. Retempermg of set concrete is not permitted Completely discharge concrete at the site within one (1) hour and 30 minutes after adding cement to aggregate. In hot weather reduce this time to one (1) hour or less to prevent stiffening of concrete before it is placed. b. Protection from Adverse Weather Unless adequate protection is provided or approval is obtained, do not place concrete during rain sleet, snow or freezing weather Do not permit rainwater to increase mixing water or to damage the surface finish. If rainfall occurs after placing operations begin, provide adequate covering to protect the work. c. Placing Temperature (1) Cold Weather. Unless special provisions are made for heating the concrete mix and concrete in forms, do not place any concrete when the air temperature is below 400F or is predicted to be below 400F within the next 48 hours after placement. Provide and use protective material and heating equipment as required to maintain the temperature of the concrete surface at not less than 35oF for a period of at least 36 hours after placement. (2) Hot Weather. When the air temperature is above 85oF, use an approved retarding agent in all concrete exposed to direct rays of the sun. d. Adjusting Slump If concrete arrives at the project with slump below that specified, water may be added. Indiscriminate addition of water to increase slump is prohibited. Do not exceed either the maximum permissible water -cement ratio or maximum slump. Any addition of water above the maximum water -cement ratio must be accompanied by a corresponding quantity of cement. Mix adjustments to obtain specified slump must be approved and directed by the Engineer. 3.2 CONVEYING 03300-6 a, Objectives Handle concrete from mixer to placement as quickly as practicable while providing concrete to required quality in the placement area. Use methods which prevent loss of ingredients and segregation. b. Equipment Obtain approval of the conveying equipment. Select equipment of size and design to insure continuous flow of concrete at the delivery end. Conform to the following equipment and operations requirements. (I) Provide truck mixers agitators, nonagitating units and manner of operation conforming to requirements of ASTM C-94, "Specifications for Ready -Mixed Concrete." (2) Use belt conveyors configured horizontally or at a slope which causes no segregation or loss. Use an approved arrangement at the discharge end to prevent separation. Discharge long runs without separation into a hopper. Provide metal or metal -lined chutes. Arrange for slopes not exceeding one (1) vertical to two (2) horizontal and not less than one (1) vertical to three (3) horizontal. Chutes more than 20 feet long and chutes not meeting slope requirements may be used if concrete is discharged into a hopper before distribution. (3) (4) Pumping of concrete will be permitted only after written approval. Use a batch design and aggregate sizes suitable for pumping. 3.3 PLACING a. Preparation In addition to the previous requirements, confirm that formwork has been completed. Remove ice, excess water, dirt and other foreign materials from forms. Confirm that reinforcement is securely in place and expansion joint material, anchors and other embedded items are properly positioned Have a competent workman at the pour location who can assure that reinforcement and embedded items remain in design locations while concrete is being placed. Sprinkle semiporous subgrades to eliminate suction. Seal extremely porous subgrades in an approved manner. b. Procedure (1) Deposit concrete continuously, or in layers of such thickness that no concrete will be deposited on concrete which has hardened sufficiently to cause formation of seams or planes of weakness within the section. If the section cannot be placed continuously, place construction joints as specified or as approved. (2) Proceed with placement at a rate such that concrete which is being integrated with fresh concrete is still plastic Do not deposit concrete which has partially hardened or has been contaminated by foreign materials. (3) Remove temporary spreaders from forms when the spreader is no longer useful. Temporary spreaders may remain embedded in concrete only if made of galvanized metal or concrete, and if prior approval has been obtained Do not start placing of concrete in supported elements until concrete previously placed in columns and walls is no longer plastic. Deposit concrete as nearly as practicable in its final position to avoid segregation due to rehandling or flowing. Do not subject concrete to a procedure which will cause segregation. 03300-7 (6) Where surface mortar is to be the basis of a finish, especially those designated to be painted, work coarse aggregate back from forms with a suitable tool to bring the full surface of mortar against the form. Prevent formation of excessive surface voids (7) Consolidate concrete by vibration, spading, rodding or forking so that concrete is thoroughly worked around reinforcement, around embedded items and into corners of forms. Eliminate air or stone pockets which may cause honeycombing pitting or planes of weakness. A minimum frequency of 7000 revolutions per minute is required for mechanical vibrators. Do not use vibrators to transport concrete within forms. Insert vibrators and withdraw at points from 18.to 30 inches apart. At each insertion vibrate sufficiently to consolidate concrete, generally from 5 to 15 seconds. Do not over - vibrate causing segregation. Keep a spare vibrator on the site during concrete placing operations. c. Concreting Under Water When required or permitted, deposit concrete under water by an approved method. Obtain advanced approval of the method from the Engineer. Deposit concrete in such a way that fresh concrete enters the mass of previously placed concrete from within, causing water to be displaced with a minimum disturbance at the surface of the concrete 3.4 REPAIRING SURFACE DEFECTS a. Defective Areas Repair defective areas immediately after the removal of forms. (1) Remove honeycombed and other defective concrete down to sound concrete. To prevent absorption of water from patching mortar dampen the defective area and a strip six (6) inches wide surrouning the area to be patched. Prepare bonding grout by mixing approximately one (1) part cement to one (1) part fine sand passing a No. 30 mesh sieve. Mix to a consistency of thick cream, and brush thoroughly into the surface. (2) Make patching mortar of the same materials and of approximately the same proportions as concrete, except omit coarse aggregate. Prepare mortar with not more than one (1)ts sand by damp loose volume. Substitute white Portland cement for part oparte cement toray Portland cement parts on exposed concrete in order to produce a color matching the color of surrounding unding concrete. Determine color by making a trial patch. (3) Use no more mixing water than necessary for handling and placing. Mix patching mortar in advance and allow to stand. Mix frequently with a trowel until it has reached the stiffest consistency that will permit placing. Do not add water. (4) After surface water has evaporated from the area to be patched, thoroughly brush a coat of bond grout into surface. When bond grout begins to lose its water sheen, apply the premixed patching mortar. Thoroughly consolidate the mortar into place and strike off to leave the patch slightly higher than the surrounding surface. To permit initial shrinkage, leave undisturbed for at least one (1) hour before final finishing. Keep the patched area damp for seven (7) days. Do not use metal tools in finishing patches in a formed wall which will be exposed. b. Tie Holes Patch tie holes immediately after removal of forms. After cleaning and thoroughly dampening the tie hole, fill solid with patching mortar. c. Pronriet?ry Materials If permitted or required, may be used in lieu of a inal If to theo ree oud, proprietary compounds for adhesion or as patching ingedients manufacturer's recommendations. foregoing patching procedures. Use such compounds according to the 3.5 FINISHING OF FORMED SURFACES 03300-8 a. Surfaces Requiring No Finish A finish is not required on surfaces concealed from view by earth, water, ceiling, etc. in the completed structure. b. Smooth Form Finish (1) Use plywood or fiberboard linings or forms in as large sheets as practicable and with smooth, even edges and close joints. (2) Patch tie holes and defects. Rub fins and joint marks with wooden blocks to leave a smooth, unmarred finished surface. (3) Use a smooth form fmish on faces of exposed concrete. 3.6 FINISHING SLABS AND SIMILAR FLAT SURFACES a. Shaping to Contour Use strike -off templates or approved compacting type screeds riding on screed strips and edge forms to bring concrete surface to the proper contour. See the section on Concrete Formwork for edge forms and screeds. b. Consolidation Thoroughly consolidate concrete in slabs and use internal vibration in beams and girders of framed slabs and along bulkheads of slabs on grade. Obtain consolidation of slabs and floors with vibrating bridge screeds, roller pipe screeds, or other approved means. Concrete to be consolidated must be as dry as practicable. Do not permit manipulation of surfaces prior to finishing operations. c. Tolerances for Finished_Surfaces Tolerances are checked by placing a straightedge of specified length anywhere on the slab The gap between slab and straightedge must not exceed the tolerance listed for the specified class. Class Straightedge Length Tolerance In Feet In Inches A 10 10 1/8 C 2 1/4 1/4 d. Floated Finish (1) After concrete has been placed, struck off, consolidated and leveled, do not work further until ready for floating Begin floating when water sheen has disappeared, or when the mix has stiffened sufficiently to permit proper operation of a power -driven float. Consolidate the surface with power - driven floats. Use hand floating with wood or cork -faced floats in locations inaccessible to a power - driven machine and on small, isolated slabs. (2) Recheck tolerance of the surface after initial floating with a 10-foot (10') straightedge applied at not less than two (2) different angles. Cut down high spots and fill low spots to Class B tolerance Immediately refloat slab to uniform, smooth, granular texture. e. Troweled Finish (1) To obtain a troweled fmish, a floated fmish as previously specified must be applied. After power floating, use a power trowel to produce a smooth surface which is relatively free of defects but which 03300-9 (2) Hot Weather. When necessary, make arrangements for installation of windbreaks, shading, fog spraying, sprinkling, ponding or wet covering of light color in advance of placement. Take such protective measures as quickly as concrete hardening and finishing operations will allow. Temperature Changes. Control changes in temperature of concrete at a rate as uniform as possible. Do not permit a temperature change to exceed 50F in any one hour or 500F in any 24 hour period. g. Protection From Mechanical In' During the curing period, protect concrete from damaging mechanical disturbances, particularly load stresses, heavy shock and excessive vibration. Protect finished concrete surfaces from damage caused by construction equipment, materials, or methods and by rain or running water. Do not load self- supporting structures in any way that overstresses concrete. (3) --o00 nib - 03300-11 0 ............................. PRODUCER JOHN L. WORTHAM & SON, L.L.P. P O.
