Contract prior to this amendment: Previous Amendment(s): 670,754.00$ Cost & Time Change Summary Pearlandtx.gov/projects Description of Work 6/10/2026 In the early stages of the project, the design engineer introduced design alternatives for the project to assess possible savings if the scope were to change. The alternatives were reviewed, discussed and approved by the City project team and City Engineer in a meeting held 4/3/24 . Savings were established in a document titled "Veterans Drainage Improvements Detention Pond Alternatives Analysis" dated 4/29/24. Overall cost savings were estimated to be $2.1M if a new detention pond was installed along Veterans Drive as opposed to the original scope that involved more piping. The initial contract scope did not include the newly proposed detention pond hence the cost proposal.

Gauge Engineering 11750 Katy Freeway, Suite 400 Houston, Texas 77079 Re: Revised Supplemental Geotechnical Investigation Proposal City of Pearland Veterans Drive Improvements From W. Walnut Street to Mary’s Creek Pearland, Texas AEC Proposal No. G2023-05-06S1R1 Dear Mr. Qaddo, Aviles Engineering Corporation (AEC) is pleased to present this revised supplemental geotechnical investigation proposal for the City of Pearland’s proposed Veterans Drive Improvements project, from W. Walnut Street to Mary’s Creek, in Pearland, Texas. Based on the schematic drawing provided, the additional scope includes construction of a detention basin southeast of the intersection of Veterans Drive and Summer Lane. According to the information provided by you, the proposed detention basin will have a maximum depth of approximately 10 feet. Based on the schematic drawing provided, the proposed detention basin area will be approximately 1.2 acres. AEC assumes that the services in this supplemental proposal will be performed at the same time as AEC’s proposal for the roadway drainage improvements, AEC Proposal G2023-05-06, dated May 11, 2023. To cover the proposed detention basin, AEC proposes to drill a total of one soil boring (Boring B-6) to 20 feet deep. The total drilling footage is 20 feet. A Proposed Boring Location Plan (showing the supplemental proposed boring location as well as the proposed roadway drainage boring locations) is presented on Plate 1, in the Attachments. We will perform a site reconnaissance prior to drilling and mark the boring location. We will also contact the Texas 811 System to confirm utility locations; however, Texas 811 does not locate water, sanitary, or storm sewer lines. We request that any existing underground utility drawings of the project alignment be provided to AEC prior to mobilization of the drill rig. Based on aerial photographs, AEC assumes that the access to the boring in the proposed basin area will require a buggy-mounted drilling rig. AEC anticipates that tree clearing will be required to access the boring location in the proposed basin area. For the boring, we will collect samples continuously at 2-foot intervals from the ground surface to a depth of 20 feet. Undisturbed samples will be obtained of cohesive soils by pushing a Shelby tube (ASTM D-1587). Standard Penetration Test samples will be obtained of granular soils (ASTM D-1586). Representative portions of all soil samples will be sealed, packaged, and transported to our laboratory. We will note any visual evidence or odor indicating hazardous materials if encountered in the samples. Water level readings will be noted during drilling and obtained upon completion of drilling. Upon completion of drilling, the borehole will be backfilled with bentonite chips. AEC requests that Gauge Engineering arrange right of entry access to the detention pond property before mobilization of the drill rig. Laboratory testing may consist of moisture contents, Atterberg limits, percentage passing No. 200 sieve, sieve analysis, unconfined compression (UC), and unconsolidated-undrained (UU) triaxial tests depending on the soil types encountered. A consolidated-undrained (CU) triaxial test and crumb tests will be performed for the detention basin boring depending on the soil types encountered.

We will present our findings and recommendations as a supplement to the geotechnical engineering report for the roadway drainage improvements. The estimated lump sum fee for our services is $18,359.50 as presented on the Itemized Fee Estimate in the Attachments. The fees are based on the following assumptions: (1) the field personnel will use Level D protection during the field exploration; (2) no standby time (weather-related or incurred due to reasons beyond our control) is included; and (3) surveying, environmental testing and evaluation, and construction document review are not included. AEC understands that the notice to proceed for the roadway alignment and the detention basin will be provided at the same time, and all the field work for the roadway drainage and the detention pond will be performed at the same time. After receiving notice to proceed and right of entry to private properties along the alignment, AEC will perform a site reconnaissance within 3 days and contact Texas 811 to clear utilities at the boring locations. Weather permitting, and assuming no field delays, we plan to start the field exploration about 1 to 2 weeks after all utilities are cleared. The field exploration for the additional detention pond scope will take approximately one day. Laboratory soil testing for the additional detention pond scope will require three to four weeks (due to CU triaxial test) to complete after completion of the drilling, and the draft geotechnical report (for the original roadway drainage scope as well as the additional detention pond scope) will take 2 to 3 weeks after laboratory testing is completed. We will submit the final geotechnical report two weeks after we receive review comments on the draft report. The provided time frame is an estimate based on AEC’s current schedule at the time this proposal was written and will remain valid for 60 days from the date of the proposal. If project authorization is received after 60 days, then the schedule estimated herein may be subject to change. If any of the project details described in this proposal are incorrect or the scope described or the assumptions listed need to be revised, please inform us immediately so we can revise the proposal as necessary. Please sign and return this proposal (including terms and conditions) or issue AEC a Professional Services Agreement (referencing this proposal) to authorize AEC to proceed with the services.
