City of Corpus Christi P. O. Box 9277 Corpus Christi,TX 78469-9277 Ref: Proposal for Geotechnical Services 18115A Dr. Hector P. Garcia Park Hike&Bike Trail—Phase II Corpus Christi,Texas TWE Proposal No.: P18-C122 Dear Ms.Alaniz, 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. Project Overview The project consists of the Phase II portion, from Trojan Drive to Home Road, of the Hike and Bike Trail at Hector P. Garcia Park in Corpus Christi, Texas. The project will include two separate Hike and Bike trails which will connect to either side of the Phase I trail. New trail kiosks along with way stations will be constructed with paved plazas,benches, water facilities, took kiosks, and shade structures. 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 suitable hike and bike trail pavement system for the new facilities. Field Program As requested, the subsurface conditions at the site will be explored by performing two (2) test borings at the locations indicated in the Request for Proposal. We propose to drill and sample each test boring to a depth of 10-ft below existing grade. Based on our knowledge of the site, we anticipate that truck mounted drilling equipment can be used to access the boring locations. The test boring locations will be identified by TWE and 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 soil boring locations. If necessary, pricing for these services can be provided upon request by the Client.

TWE Proposal No.P18-C122 We anticipate underground utilities and pipelines could be of concern at the site location. Our field personnel will work with appropriate City of Corpus Christi 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 soil borings will be logged by an experienced geotechnician. We will dry-auger the soil 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 soil borings. Geotechnical drilling and sampling will be performed in accordance with ASTM International standards. Samples will be obtained continuously to the termination depth of 10-ft. 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. Upon completion of drilling and sampling, the boreholes will be backfilled with cuttings and surrounding surface soils as needed. Any remaining cuttings from the drilling operations will be spread on the ground surface around the borings. 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, various types of shear strength, 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 hike and bike trail section. We will recommend suitable hike and bike trail section for the project. We will present the results and findings of our geotechnical services in written reports. Electronic and hard copies of our final reports will be issued to the Client as requested. Our final reports will include the following: a. Summary of field and laboratory tasks; b. Discussion and conclusions of our findings including: i. Project site conditions; Houston • Dallas • Corpus Christi • La Porte • Beaumont • Lake Charles • Baton Rouge • New Orleans Page 2 of 4 Exhibit A Page 2 of 4 • ITO Tolunay-Wong 31,218 Engineers, Inc.

Geotechnical design recommendations for suitable hike and bike trail including hot mix asphalt concrete and reinforced concrete pavement sections for pedestrian traffic only, for pedestrian and occasional pickup/trailer use, and for pedestrian and heavy equipment use for 30 year deign life; d. In-situ soil classification based on OSHA standards for trench safety; and, e. Geotechnical construction recommendations including site and subgrade preparation, excavation considerations, fill material requirements and placement, compaction requirements, foundation installation, and overall quality control monitoring,inspection and testing services. Schedule Upon authorization,our field program can typically commence within five(5)working days depending on our current schedule, site access, weather contingencies and subsurface utility clearance. We anticipate the field program will take one(1) day to complete with laboratory testing beginning as soil samples are returned to the laboratory. We anticipate being able to complete all laboratory testing within one(1)week. Engineering analysis and preparation of our final report will require one(1)week after all laboratory testing is completed. We anticipate an overall project duration of about four (4) 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. Estimated Cost The estimated cost associated with our geotechnical services for this project is presented below. Every reasonable effort will be made to stay within this proposed budget. Should unforeseen conditions or situations occur that are beyond the control of TWE, we will not exceed this lump sum amount without prior approval from the Client.
