SUBJECT: PROPOSAL TO PERFORM A SUBSURFACE INVESTIGATION, LABORATORY TESTING PROGRAM,AND PROVIDE GEOTECHNICAL RECOMMENDATIONS FOR THE PROPOSED NEW WATER LINE ON FLOUR BLUFF CORPUS CHRISTI,TEXAS 18094A Citywide Water Distribution System Repair Replacement IDIQ(Year 2) Task Order#2 RETL Proposal Number: P100119A Dear Ms. Gomez, Rock Engineering and Testing Laboratory, Inc. (RETL) (TBPE Firm No. 2101) is pleased to submit the following proposal to provide a subsurface investigation, laboratory testing, and provide geotechnical recommendations the new water line along the east side of Flour Bluff Drive from the intersection of Yorktown Boulevard to the intersection of Division Street located in Corpus Christi,Texas. Based on information provided to RETL, the project will include the replacement of the city water transmission main.The proposed alignment of the water transmission main will be located within the right- of-way of Flour Bluff Drive 10 to 15 feet from the edge of pavement. The project includes approximately 12,000 linear feet of 24-inch water main installed by conventional trenching methods and approximately 6,203 feet of 24-inch water main installed by horizontal directional drilling (HDD). The water main installed by conventional trenching will have a minimum of 36-inches to 48-inch of cover. In the trenched segment, the pipe will be typically placed directly onto a sandy/granular bedding and encased in the same material. Trench backfill from at least 12-inch above the pipe to existing grade will be backfilled with in- situ native material. Based on the information provided by the City of Corpus Christi's Engineering Services Department and based on RETLs experience with soils in the area of the project, RETL will perform four borings to a termination depth of 25 feet, at each designated location provided by the City of Corpus Christi. (Total number of Borings: 4; Total linear feet of Drilling: 100 LF). The scope of work is outlined below. ROCK ENGINEERING&TESTING LABORATORY,INC.

The borings/cores will be relocated if necessary. • RETL will utilize signage and safety cones as necessary to provide a safe work site during our field investigation. • The borings will be sampled every 2.5-feet to the termination depth of the borings. • Groundwater readings will be obtained during drilling and immediately upon completion of the drilling operations. • After obtaining the delayed groundwater readings, the open boreholes will be backfilled with excess soils obtained during the drilling operations. Scope of Laboratory Testing Program • Supplementary Visual Classification (ASTM D2487) • Water Content Tests (ASTM D2216) • Atterberg Limits Tests (ASTM D4318) • Percent passing No. 200 (ASTM Dl 140) • Sieve Analysis(ASTM D6913) The preceding test methods may be performed on selected samples, depending on the actual subsurface conditions encountered. All phases of the laboratory testing program will be performed in general accordance with applicable ASTM Specifications. All laboratory test results will be provided in the report or included on the boring logs. Projected Schedule After authorization, it is estimated that the drilling operations can begin within 5 to 10 business days and the final report will be submitted within three weeks of the completed fieldwork. RETL will consult with the engineers as field and laboratory test results become available by providing preliminary recommendations as required to assist in design. If adjustments to the proposed timeline are required to meet the existing project schedule, please contact RETL so that we can accommodate your needs. Geotechnical Engineering Report In addition to the field and laboratory testing, a geotechnical engineering report will be prepared that includes a description of the field exploration and laboratory tests, boring logs, a discussion of the engineering properties of the subsurface materials encountered, trench excavation design parameters, OSHA soil type classification, and utility trench earthwork recommendations.

Therefore,by providing cost information,we are not in violation of the Texas Professional Services Procurement Act. The total fee to perform the scope of work outlined above is $7,800.00. The total project fee includes the field investigation, laboratory testing, geotechnical and pavement recommendations, and report preparation. The following items will be added to the final invoice as required: 1. Additional drilling required due to subsurface conditions: $95.00 per linear foot. 2. Additional HMAC cores: $300.00 per core. 3. Standby time: $275.00 per hour/per company. Please note that the total fee provided above will be honored for 90 days after the date of this proposal. After 90 days, RETL should be contacted to reevaluate the fees and revise the proposal as needed. Services provided for any revisions after the submittal of the final report,approved by the client in a change order, will be invoiced at a rate of$180.00 per hour. The total fee to perform the scope of work does not include site assistance in the event the boring/core locations are inaccessible. Mechanical assistance required to access the boring locations will be assessed based on the subcontractors' hourly fee plus the mobilization fee. The total fee does not include development and implementation of a traffic control plan or traffic control devices, should it be required. Services provided by RETL under this Agreement will be performed in a manner consistent with the degree of care and skill ordinarily exercised by members of the same profession currently practicing under similar circumstances.
