Box 6355 Corpus Christi, Texas Reference: Subsurface Investigations - Contract Nos. 3 and 5 Oso Wastewater Treatment Plant Improvements Corpus Christi, Texas Dear Mr. Urban: This letter and attachments reflects the scope of services and estimated cost for providing a subsurface investigation for the above referenced projects. I have reviewed all the information provided concerning the various improve- ments including the plant effluent lines, lift stations, and the major plant structures. I essentially agree with your recommended boring locations and depths with only minor changes in the boring depths in the plant area as con- firmed with Mike Carrell of your office. For convenience, the specific bor- ings and proposed depths are summarized below: Contract No. 3 B19 Airline Rd. 0 Wooldridge 35.0' B20 Wooldridge Dr. @ Co.

To provide additional long -term groundwater observations, we propose to install perforated P.V.C. pipe in three of the core borings, one at lift station 05 and two at the major plant structures. This information could prove to be valuable to your designs. The subsurface materials will be visually classified and described. Atter- berg Limits tests and minus 200 mesh sieve tests will also be conducted on a limited basis to aid in these classifications. Strength evaluations will be made through'either unconfined compression tests of cohesive soils or standard penetration tests in granular soils. For proposal purposes, one strength test for each five feet of core drilling has been included. The only other laboratory tests which could be required are consolidation tests for evaluation of compressibility characteristics of cohesive soils. The results of the field and laboratory investigations will be used by our geotechnical engineer to provide soil characteristics and properties required for the final design of the various plant structures. We will coordinate these studies with your personnel to provide specific recommendations that you may require in your design. All the information obtained, including our foundation recommendations, will be presented in a formal report. The estimated cost of this scope of ser- vices is $7,078.00 as itemized on the attached Professional Services Estimate sheets. These estimates were made for contract no. 3 and no. 5 separately for your benefit. We look forward to working with you. If you have any questions concerning this proposal, please feel free to call me. Sincerely, TRINITY ENGIINEERING TESTING CORPORATION QrP/1k / l..'6mtZ4 Robert C. Davis, Ph.D.,P.E.
