O. Box 9277 Corpus Christi, Texas 78469-9277 Attn: Mr. Eliborio (Eli)Pena, P.E. Engineer IV—Facilities Project Manager EliborioP@cctexas.com Ref: Proposal for Geotechnical Engineering Services E16458 Restoration of S.E.A. District Water Features-Water Gardens Corpus Christi, Texas TWE Proposal No.: P 19-C 100R1 Dear Mr. Pena, Tolunay-Wong Engineers, Inc. (TWE) is pleased to submit this revised proposal to provide geotechnical engineering services for the referenced project. This proposal presents a general description of the project, our proposed scope of services to be provided, and the estimated cost for completion of our services associated with the project. Project Overview We understand the project will involve construction of a pump building near the northwest corner of the American Bank Center in Corpus Christi, Texas. The building will be built at-grade and have a below grade portion (vault) that houses the water pumps. The vault bottom will be about 20-ft to 25-ft below existing grade. The at-grade portion will have a slab-on-grade floor and will house electrical and mechanical features and controls. It is anticipated that the building superstructure and the floor slab will be supported with helical piles. We anticipate that structural loading imposed by building will not be more than about 50 to 75 kips per pile. We also understand that the vault will be constructed with steel sheet piles. A new structural concrete pavement will be constructed at the location of an existing sidewalk. Scope of Services We will provide the personnel, equipment and materials necessary to complete the requirements of our scope of services. Our scope of services can be categorized into three major areas: field program, laboratory testing, and engineering analysis/report preparation. The purpose of our geotechnical engineering services will be to provide the geotechnical information needed to assist the Client in the design and construction of suitable foundation system for the planned building and a structural concrete pavement.

July 30,2019 �� TWE Proposal No.P19-C100R1 Field Program The following scope of services was developed in concurrence with the project civil and structural engineering firm (LNV, Inc.). We propose to explore subsurface conditions by performing two (2) test borings at the site, each extended to a depth of 75-ft below existing grade. We anticipate that the test borings can be accessed using conventional truck-mounted drilling equipment, weather permitting. The test boring locations will be surveyed using a hand-held global positioning system (GPS) device. This proposal does not include pricing for professional surveying services to provide precise coordinates and elevations of the test boring locations. If necessary, pricing for these services can be provided upon request by the Client. We anticipate underground utilities and/or pipelines could be of concern at the site location. Our field personnel will work with appropriate City personnel to identify and avoid any known City owned underground utilities. We will notify the Texas 811 One Call System prior to the commencement of our field program for clearance of subsurface utilities within the project site. Our field personnel will have the appropriate safety training and will be equipped with the required personal protective equipment. Our geotechnical engineering services will be under the direction of a Professional Engineer experienced in geotechnical engineering. Our test borings will be logged by an experienced geotechnician. We will dry-auger the test borings until groundwater is observed or until borehole conditions require the use of wash-rotary drilling methods. When groundwater is encountered, the level will be allowed to stabilize for about ten (10) minutes to fifteen (15) minutes prior to completing the test borings. Geotechnical drilling and sampling will be performed in accordance with ASTM International standards. Samples will be obtained at 3-ft intervals to a depth of 20-ft and at 5-ft depth intervals thereafter until the boring completion depth is reached. Fine-grained, cohesive soils will be sampled using pushed, thin-walled Shelby tubes with an inside diameter of 2.87-in. Our geotechnician will conduct field strength measurements using a pocket penetrometer or hand torvane device on each cohesive soil sample recovered. The samples will be wrapped in foil, placed in moisture sealed plastic bags and handled to minimize disturbance prior to transport to our laboratory. Where coarse-grained, cohesionless and semi-cohesionless soils are encountered, sampling will be performed using standard penetration test (SPT) methods. Our geotechnician will monitor the driving resistance and record blow counts while performing the SPTs. The disturbed samples from the SPT sampling will be placed in moisture sealed plastic bags and delivered to our laboratory. Cuttings and fluids from the drilling and sampling operations will be spread at the ground surface adjacent to the test boring locations. The test borings will be backfilled with cement-bentonite grout upon completion. Laboratory Testing Selected samples from the test borings will be used for laboratory testing. Our laboratory testing program will include properties such as moisture content, unit weight, Atterberg Limits, grain size distribution, and various shear strength tests.

TWE Proposal No.P19-C100R1 Engineering Analysis/Report Preparation Engineering analysis will be conducted utilizing the information collected during our field program and laboratory testing services. Analyses will include foundation bearing capacity determination, settlement prediction, foundation construction considerations as well as structural concrete pavement section. We will provide foundation installation, pavement, and earthwork recommendations for the project. We will present the results and findings of our geotechnical engineering services in a written report. Electronic and hard copies of our final report will be issued to the Client as requested. Our final report will include the following: a. Summary of field and laboratory tasks; b. Discussion and conclusions of our findings including: i. Project site conditions; ii. Subsurface soil and groundwater conditions; and, iii. Boring logs presenting tabulated field and laboratory test results; c. Geotechnical parameters for helical pile foundation design such as soil unit weight, undrained shear strength (cohesion) for cohesive soils, and angle of internal friction for cohesionless and semi-cohesionless soils for the site soil profile; d. Geotechnical parameters for steel sheet pile wall design such as soil unit weight, undrained shear strength (cohesion) for cohesive soils, and angle of internal friction for cohesionless and semi-cohesionless soils for the site soil profile and recommended sheet pile wall embedment depth; e. Geotechnical design recommendations for structural concrete pavement section including subgrade preparation and required concrete thickness; and, f. Geotechnical construction recommendations including site and subgrade preparation, excavation considerations, fill and backfill placement, compaction requirements, foundation installation and overall quality control monitoring, inspection and testing services. Schedule Upon authorization, our field program can typically commence within 5 working days depending on our current schedule, site access,weather contingencies and subsurface utility clearance. We anticipate the field program will take 2 days to complete with laboratory testing beginning as soil samples are returned to the laboratory. We anticipate being able to complete all laboratory testing within 2 weeks. Engineering analysis and preparation of our final report will require 2 weeks after all laboratory testing is completed. We anticipate an overall project duration of about 4 to 5 weeks from notice to proceed to completion of our report. During this time, we will communicate with the Client and provide preliminary information as needed to avoid delays in the overall project schedule.
