Re: Surface Water Plant Engineering Construction Phase Services
This memo provides information aboutthe progress on the Surface WaterTreatment Plant project's current
status and the forthcoming proposed award of the Balance of Plant GMP for the CMAR, three contract
Amendments for Engineering Construction Phase Services and one additional Task Order for Owner's
Representative Construction Phase Services. These contracts are scheduled for presentation to Council on
the September 28, 2020 meeting agenda.
Background
The Surface Water Treatment Plant project is designed to provide up to 10 million gallons per day (MGD) of
safe clean drinking waterforthe citizens of Pearland beginning in January2023. This facilitywill supplement
ground and other surface water sources currently in operation and reduce the City's dependence on
expensive water supplied through an existing take or pay contract with the City of Houston on the far west
side of the City.
Design of the facility was split into 3 design packages and awarded separately with Freese & Nichols
managing Package 1: Site Drainage and Raw Water Lift; CDM -Smith managing Package 2: Treatment Plant
and associated facilities; and Stantec managing Package 3, high service pumps and building, ground storage
and transmission lines.
Council awarded the Construction ManagerAt Risk Pre -Construction Services contractto PLW WaterWorks
in April 2019 and awarded the Early Works Package 1 (EWP1), in the amount of $7,479,256.00 in February
2020. TWDB issued a final approval in late April for this package. Early Works Package 2 (EWP2) was
awarded in April 2020 in the amount of $13,758,502 and TWDB issued their approval in mid-June.
Current Status
Work on portions of the two Early Works Packages began on site almost immediately with large portions of
the rough site work and drainage now underway or partially complete. Soil foundation work for the plant's
several buildings and ground storage tank are also now nearing completion. Deep foundation work is well
underway on the thickeners and wash water recovery basins. The Early Works package has allowed the
deep foundation work to be done without the need or cost of expensive shoring. Progress on the early works
packages is observable in aerials photos attached to the end of this memo. The site rough grading and
preliminary drainage is in place making the site workable even afterthe heavy rains experienced in late July
and early August.
The CMAR received bids for the manufacture and supplyof plant membrane units in late -February 2020 and
Staff has recently completed work with the Design Consultant to negotiate final equipment package details
to improve the performance of the membrane equipment and to incorporate manufacturer performance
recommendations. These were necessary to obtain the increased thru-put capacity desired. Themembrane
package, consisting of three racks of membrane modules, piping, valving, pumps, instrumentation and
controls, will have the ability and capacity to process the required 10 Million Gallons per Day (MGD) of
drinking water.
All three design consultants submitted plans and specifications to TCEQ for final approvals in July. At this
time TCEQ has completed their reviews of Packages 1 and 2. All three Packages were also submitted to the
City for permitting in early August on schedule. Plans have been designated as ISSUED FOR BID as they
have not been finally approved by TCEQ, TWDB or the City constituting approximately 90% design level of
effort. The CMAR advertised for bids to his pre -qualified bidders and held Pre -Bid meetings July 7th and 101h
to answer any questions and provide clarifications for all bid packages. The packages contain the Balance
of Project (BOP) work and form the basis for the CMAR's final GMP. Bid packages were assembled to
maximize the economies of scale including labor, material and equipmentwhere possible. Other, "Equipment
Only" packages were developed to group like equipment, such as pumps, into one purchase to capture these
economies.
Bids were received in August and the CMAR has reviewed and analyzed each bid to ensure that the sub-
contractor or vendor has included the entire scope of work and understands all specifications. The vetting
process has included interviews of perspective sub -contractors in which Staff and the Owner's Rep have
participated to ensure qualified sub's are awarded contracts and that cost reduction recommendations from
these sub's were taken into consideration for Value Engineering purposes.
The CMAR submitted bids to self -perform three packages within the BOP work and was low bidder on two
of those: Yard Piping and Membrane and the Chemical and Granular Activated Carbon (GAC) facilities. The
third package was the Dewater Deep Structure Equipment package which will ultimately be awarded to the
low bidder, an MBE contractor. In all such cases, the CMAR submitted his bid to the Owner's Representative
24 hours before competitors bids were received.
Working from the submitted results the CMAR delivered a preliminary GM P in late August along with a list
of potential Value Engineering options that, once analyzed, could reduce the Cost of Work by as much as $1
million dollars further. That Preliminary GMP is currently $135,997,681. This is the total for ALL Work
INCLUDING the Pre -Construction Services ($1,092,320) the previously awarded Early Works
Packages totaling $21,237,758 leaving the Balance of Project Costs of $113,667,603. As VE items are
reviewed and accepted the GMP will reduce further. Staff will present this Guaranteed Maximum Price
(GMP) to Council for approval and award on September28th.
The following table lists the packages and their respective costs that make up the balance of project work
that produce the GMP.

Schedule Info
At this time, the Design portion of the project is largely complete with minimal design or plan changes
anticipated for permitting and final State approvals. The Design Consultants have all met their planned
delivery dates. The previous efforts to get early work packages (EWP1 and EWP2) started has paid off in
that a good deal of site work is already underway despite the delays in approvals at TWDB and the rain days
experienced on site in June and July.
However, TWDB's approval of work packages has been slow. Work contained in Early Works Package 1
was not approved by TWDB until April 21 t Some portions of work in Early Works Package 2 was finally
approved on June 10th leaving some portions still un -approved. Initially, individual bid packages within the
Early Works packages were being reviewed and assessed as if each sub -contract package was a separate
project requiring independent review, duplication of all front-end documents and environmental clearances.
Seeking to maintain the project schedule, Staff provided NTPs to the CMAR for portions of these packages
as soon as TWDB approvals came in. As a result, portions of field work were able to proceed but, progress
has suffered from these delays due to TWDB's slow approval procedures and their lack of complete
understanding of the CMAR process. TWDB is in the process of creating their review/approval processes
for this alternative delivery methodology. The combination of lack of understanding and absences of existing
procedures is at the heart of these delays. The project Team met with TWDB in early June and presented an
informational package containing an in-depth discussion on the CMAR process as described in Title 10:
Chapter 2269.255 of Government Code. This discussion focused on the commercial aspects of the sub-
contractor bidding process, the development of sub -contract bid packages and offered guidance for the
development of TWDB's forthcoming procedures.
Although TWDB's procedures are being created at this time, the delay to the work has cost the project
approximately six months in the overall schedule. Schedule recovery discussions with the CMAR indicate
that "float" available in the original schedule has nowbeen consumed by the TWDB delays and has pushed
construction completion into December 2022 and commissioning of the plant into early 2023 versus a
planned completion of mid -year 2022 with full operations and testing complete before December 2022.
Timing for final water to the system will be dependent on the project schedule for Plant Commissioning. The
exact Commissioning schedule is anticipated to be early first quarter of 2023 but will be refined based upon
system components beginning to come on line. Our current Water Model indicates that a delay into early
2023 will not cause an impact on our water system.

Next Steps
As the project moves into the Balance of Project (BOP) Construction Phase, engineering contracts will need
to be amended to provide engineering services during construction or "Construction Phase Services". All
three Design Consultants will be needed forthe Construction Phase, albeit at differing levels of involvement,
based on the complexity of earlier design contributions. Additionally, The Owner's Representative Master
Service Agreement contract with Ardurra will require the addition of Task 5 for Construction Phase Services.
Construction Phase services were not included in any of the previous Preliminary or Final Design contracts
in order to simplify those scope definitions and fee negotiations.
All three Design Consultant Packages will be presented as contract amendments to the existing Final Design
Services contracts. All three Contract Amendments will have very similar scopes of services and will be
based on an Hourly Not to Exceed billing. Scope of work in all three will contain but may not necessarily be
limited to:
• Personnel hours for attending on-site progress meetings as well as virtual meetings during
construction and occasional site visits to monitor work progress and quality control.
• All three will contain hours for reviewof material and product submittals,
o addressing Requests for Information (RFIs).
o This work will include hours for sub -consultant involvement where the source of design was
vested in third parties contracted to the prime consultant.
• Each proposal will also include hours for project completion and assistance during start up services
which will include inspections at substantial and final completion for the major components within
their respective packages.
• Hourly fees for the creation of record drawings from the CMAR's redlined records.
• Each proposal will include hours for additional services as authorized which will cover hours for
o unforeseen problem resolutions, additional submittal review and approval work,
o redesign of work to meet constructability issues and
o additional hours for extended startup and commissioning services if required.
Staff Plan to bring all three proposals; Packages 1, 2 & 3, for Construction Phase services to Council for
award at the September 28th meeting.
Package 1, Freese and Nichols' proposal includes Basic Services in the amount of $152,215 and Additional
Services of $40,226 for a total of $192,441
Package 2, CDM/ Smith's proposal includes Basics Services in the amount of $1,315,721 and Additional
Services of $603,380 for a total of $1,919,101.
Package 3, Stantec's proposal includes Basic Service in the amount of $688,640 and Additional Services of
$150,810 for a total of $839,450.
Finally, Staff will bring Task Order #5 for Ardurra Group's Owner's Representative contract for Construction
Phase Services. This scope of work is based on Hourly, Not to Exceed basis and consists of Basic Services
includes hours for continued coordination with TWDB on funding issues and TCEQ for regulatory issues
during construction as well as hours for continuing to coordinate between design package consultants,
attending monthly progress meetings, trouble shooting and problem resolution all under the Project
Management category. Basic Services total $1,339,405
Additional Services (also Hourly, Not to Exceed) include site inspection and construction management based
on the 27 month construction and start-up schedule, on-call as authorized water system modeling,
coordination and responsibility for completing the Operations and Maintenance Manual, performing a
feasibility analysis including 3 alternatives for the future development of a plant forebay and engineering
support during the 12 month warranty period. Additional Services total 1,785,609. Total for all Owner's
Representative Construction Phase services during construction is $3,125,014
Recommendation
On April 271h Staff will recommend that Council:
• Approve the Guaranteed Maximum Price for the project of$135,997,681 and Award to Balance of Project
Amendment to PLW Waterworks
• Approve amendments to all three Design Package contracts for Construction Phase Services
• Approve the amendment to the Owner's Representative's contract for Construction Phase Services
