City of Corpus Christi P. O. Box 9277 Corpus Christi,Texas 78469-9277 (361) 826-3500 email: SarahW2@cctexas.com Ref: Proposal for Geotechnical Services E16318 Marina Breakwater at McGee Beach Improvements Corpus Christi,Texas TWE Proposal No.: P18-0093 Dear Ms. West, Tolunay-Wong Engineers, Inc. (TWE) is pleased to submit this proposal to provide geotechnical 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 The project involves repair of the McGee Beach Breakwater in Corpus Christi, Texas. The general site location for the breakwater is shown on the attached Google Earth image. Geotechnical 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 services will be to provide the geotechnical information needed to assist the Client in the design and construction of repairs to the breakwater. Field Program As requested, the subsurface conditions at the site will be explored by performing seven (7) marine test borings, each extending to a depth of 40-ft below the mud line (i.e., bottom of Corpus Christi bay). In the event soft soils are encountered at the 40-foot depth, the boring(s) will be extended an additional 10-ft. In the event sands are present at the 40-foot depth, the boring(s) will be extended into the underlying clay layer. We understand that at this time the water depth at the marine borings is assumed to be from 5 to 15 feet MLLW. The test boring locations will be near the proposed locations indicated on the attached Proposed Soil Boring Location Map provided by LAN.

July 17,2018 TWE Proposal No.P18-0093 The soil boring locations will be identified by TWE and surveyed using a hand-held global positioning system(GPS) device. We understand that the final boring locations will be surveyed by Frontier Surveying, Inc. (FSI)and that we will coordinate the surveying efforts with FSI. We anticipate underground utilities and pipelines could be of concern at the site location. Our field personnel will work with appropriate personnel to identify and avoid known underground utilities. We will also 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 services will be under the direction of a Professional Engineer experienced in geotechnical engineering. Our test borings will be logged by an experienced geotechnician. The borings will be advanced using auger methods or until borehole conditions require the use of wash- rotary drilling methods. Geotechnical drilling and sampling will be performed in accordance with ASTM International standards. Samples will be obtained at 2.5-ft depth intervals to a depth of 10-ft and at 5-ft depth intervals thereafter until the boring completion depths are 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. After completion,the borings will be left to naturally fill in with marine mud. Laboratory Testing Selected samples from the soil borings will be used for laboratory testing. Our laboratory testing program will include properties such as moisture content, unit weight, unconfined compression strength, unconsolidated-undrained triaxial compression strength, consolidated-undrained triaxial compression strength with pore pressure measurements, Atterberg Limits, and grain size distribution. Engineering Analysis/Report Preparation Engineering analysis will be conducted utilizing the information collected during our field program and laboratory testing services. Analyses will include bearing capacity of soils supporting the breakwater and slope stability dredge pockets and the breakwater after repair. We will also provide subgrade preparation discussions for the project. We will present the results and findings of our geotechnical services in a written report. Electronic and hard copies of our final report will be issued to the Client as requested.

July 17,2018 TWE Proposal No.P18-0093 Our final report will include the following: a. Summary of field and laboratory tasks; b. Discussion and conclusions of our fmdings including: i. Project site conditions; ii. Subsurface soil and groundwater conditions; iii. Boring logs presenting tabulated field and laboratory test results; c. Geotechnical recommendations will include allowable bearing capacity for the rehabilitated breakwater foundation soils below the breakwater and acceptable slope angles for the dredge pockets and at least two cross-section options for the breakwater selected by LAN; d. Geotechnical guidance will be provided regarding erosion susceptibility/characterization of soils near the toe (foundation) of the breakwater;and, e. Geotechnical recommendations including subgrade preparation, excavation considerations, fill and backfill placement, and overall quality control monitoring,inspection and testing services. Sediment Sampling and Testing Scope of Services Field Program As requested, a maximum of 5 sediment, 5 water, and 5 elutriate samples will be obtained to the proposed dredge depth of-10 ft NAV88 in area 1 and area 2. Four sediment sample locations (SS- 02 through SS-05) will be positioned along the edge of the existing breakwater structure. At these locations, we plan to utilize a petite ponar sampler or a hand operated sediment core sampler to obtain samples to the proposed dredge depth. If samples to the depth of dredge cannot be obtained using hand operated equipment, the pontoon drilling rig will be utilized to obtain the samples. We plan to obtain the sample from SS-01 location utilizing a shovel or the petite ponar sampler. We understand that at this time the water depth at the marine borings is assumed to be from 5 to 15 feet MLLW. The sediment sample locations will be near the proposed locations indicated on the attached Proposed Soil Boring Location Map provided by LAN. The soil boring locations will be identified by TWE and surveyed using a hand-held global positioning system(GPS)device. We understand that the final boring locations will be surveyed by Frontier Surveying,Inc. (F SI)and that we will coordinate the surveying efforts with FSI. We anticipate underground utilities and pipelines could be of concern at the site location. Our field personnel will work with appropriate personnel to identify and avoid known underground utilities. We will also 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.
