(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 improvements to three beach access roads on North Padre Island, Texas. We understand that the improvements will include reconstruction of existing Beach Access Roads (BAR) No. 3 and 3A and new pavement construction for Beach Access Road No. 2. Based on available information from Google Earth, the lengths of the roads were approximated as 875-ft for BAR No. 3A, 1500-ft for BAR No. 2, and 2600-ft for BAR No. 3. We understand that the roadways will be constructed with a two lane configuration. Roadway design will be based on design lifes of 20-yr and 30-yr using traffic information from the City of Corpus Christi. We are not aware of any underground utilities within the roadway limits. 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 program, 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 pavement improvements/rehabilitations. Field Program The existing roadway components thicknesses, where applicable, and the subsurface conditions at each roadway site will be explored by performing a total of 13 soil borings. A summary of the boring numbers and depths are provided in the table below.

The soil 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. We anticipate underground utilities could be of concern at the site. Our field personnel will work with appropriate client 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 site. Our field personnel will have the appropriate safety training and will be equipped with the required personal protective equipment. We anticipate that traffic control will be necessary during the field program; however, since the roadways are not heavily traveled, the traffic control will consist of traffic control cones and rotating beacon lights on the top of work trucks only. Traffic control devices such as warning signs and traffic flow control mobile arrows are not planned to be used. 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 boring completion depths. The existing pavement components, where applicable, will be carefully measured for thickness and recorded on the boring logs. 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. Houston • Dallas • Corpus Christi • La Porte • Beaumont • Lake Charles • Baton Rouge • New Orleans Page 2 of 5 (10 folunay-Wong September 25,2015 Engineers, Ine• TWE Proposal No.P15-0091 Coarse-grained, cohesionless and semi-cohesionless soils will be sampled 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 at the ground surface adjacent to the soil boring locations. Existing asphalt or concrete pavement will be patched with asphalt cold patch material or sacked pre-mixed concrete, whichever is appropriate. 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, 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. We will provide geotechnical design and construction recommendations for the proposed roadways improvements. We will present the results and findings of our geotechnical services in a fmal 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. Discussion and conclusions of findings including: • Summary of field and laboratory tasks; • Existing project site conditions; • Subsurface soil and groundwater conditions; • Boring logs presenting tabulated field and laboratory test results; b. Geotechnical design recommendations for the proposed roadways improvements including flexible (asphalt) pavement and rigid (concrete) pavement sections for 20 year and 30 year design life. The pavement sections will include: • The flexible (asphalt) pavement section will include new pavement section(s) with complete reconstruction/construction and pavement section(s) with full depth reclamation by cement treatment and reuse of existing asphalt and base material, if applicable; • The rigid(concrete)section will include one reinforced section; and c. Geotechnical construction recommendations including site and subgrade preparation, in-place soil stabilization, excavation considerations, fill and backfill placement, compaction requirements, and overall quality control monitoring, inspection and testing guidelines.
