WA9302-CS 940112From the desk of... Ken Griffin, P.E. GEOTECHNICAL GEE Consultants, Inc. EI NVIRONMENTAL 2540 Glenda Lane · Suite 108 · Dallas, Texas 75229 · (214) 620-9791 · Fax (214) 620-9794 January 05, 1994 City of Coppell 255 Parkway Boulevard Coppell, Texas 75019 Attention: Mr. Ken Griffin, P.E. Proposal No.01401 Geotechnical Investigation Proposed At-Grade Water Storage Tank Coppell, Texas Dear Mr. Griffin: In accordance with our meeting of January 03, 1994, we are pleased to submit the following cost estimate for geotechnical engineering services on the above referenced project. We understand that the proposed project consists of an at-grade water storage tank to be located near the northeast corner of MacArthur Boulevard and Sandy Lake Road. As discussed, to your knowledge, an existing tank west of the proposed site is performing well from a structural standpoint. Consequently, consideration should be given to utilizing a similar foundation as an alternative. It is our understanding the existing storage tank is supported on piers with a slab supported at grade. Based on this information, requirements for this geotechnical investigation will include design parameters for a pier foundation and a slab supported at grade. Recommendations for an integral slab and grade beam foundation will be provided if soil conditions warrant this system to be a feasible alternative. As recommended, three (3) borings will be advanced in the proposed tank area. Based on our telephone conversation with Mr. Nick Legatos of The Preload Company, contractor for the first tank, piers for the existing tank were drilled to as deep as thirty-eight (38) feet and relatively shallow groundwater was encountered. Consequently, we recommend advancing our test borings to a depth of forty-five (45) feet. City of Coppeil January 05, 1994 We anticipate that the following drilling and laboratory tests will be required: Intermittent Sample Borings (approximately 135 total linear feet of borings) 4 to 6 Atterberg Limits Tests and/or Percent Passing a No. 200 U.S. Sieve 10 to 16 Moisture Content Determinations 30 to 40 Field Standard Penetration Tests and/or Unconfined Compressive Strength Tests 0 to 2 Pressure and/or Free Swell Tests This proposal is based on the assumption that the site is accessible to truck mounted drilling equipment. Soil sampling in cohesive soils will be performed with thin wail Shelby tubes in generai accordance with ASTM D1587. Granular or hard soils/rock will be sampled with a split spoon sampler in generai accordance with ASTM D1586. Soil samples will be extruded and sealed at the site and transported to our laboratory for testing. Groundwater levels in each boring will be measured at the completion of each boring and at the end of the working day. A laboratory testing program will be assigned by a geotechnicai engineer to meet the particular needs of the project after visuaily examining soil samples collected. Using periodicaily caiibrated equipment, our experienced laboratory technicians will be performing the anticipated tests listed above. A written engineering report will be prepared by a registered engineer with expertise in geotechnicai engineering. The report will include the following findings and recommendations: ft. Plan of Borings, Logs of Boring ,/2. Results of Laboratory Testing 3. Site Observations and Comments ~4. Foundation Type Selection and Design Parameters "5. Estimated Differential Vertical Movement at Test Boring Locations '6. Subgrade Preparation Procedures q. Criteria for Placement and Processing of Fill Materiais These services will be performed in accordance with our standard fee schedule. Based on information presently available and our experience, the estimated cost of this investigation, including three (3) borings, will be $2,700.00. This cost includes a meeting to discuss our findings (if desired) at the completion of our investigation . Supplemental meetings and/or GEE Consultants, Inc. Proposal No. 01401 Page 2 City of CoDpell January 05, 1994 recommendations not included in the original anticipated scope of work may be assessed using our standard rates. If near surface soft soils are encountered and consolidation testing and settlement analysis is recommended, consolidation with hysteresis tests can be performed for $300.00 each. The cost for consolidation testing would be in addition to the $2,700.00 estimated cost of the investigation. This additional testing would not be performed without prior authorization. We anticipate 1% to 2¼ weeks for completion of this investigation, weather permitting. If consolidation testing is necessary, we anticipate three (3) to five (5) weeks for completion of the investigation. We understand that we have been selected for this project and therefore, when providing this estimate, are not in violation of the engineering laws governing procurement of professional engineering contracts with public entities. If this proposal is acceptable to you, please sign the enclosed copy along with the Agreement for Geotechnical Engineering Services, and mall it to us at your earliest convenience. Thank you for the opportunity to be of service to you. Should you have any questions, please do not hesitate to contact us at your convenience. Very truly yours, GEE Consultants, Inc. Gary G.
