Ms. Laurie Anderson, P.E. July 18,2001 Page 4 Laboratory Testing: Our project engineer will review the boring logs and select representative samples for determination of appropriate soil properties. We anticipate conducting Atterberg Limits and minus #200 sieve gradation tests for soil classification, as well as determining unit weights and moisture contents of the in-situ soil strata. Unconfined compression strength tests will be also performed to evaluate soil strength, bearing capacity and settlement parameters. At your request, gee-chemical testing such as sulfate, chloride, soil-box electrical resistivity and soil pH is not included as part of the our standard scope of services for this project. An additional cost to conduct these services has been developed and is contained in the "Estimated Cost" section of the proposal. Engineering Analysis and Reports: Our project engineer will supervise the field and laboratory investigative phases, review the results of all field and laboratory tests, and prepare the formal engineering reports. As previously stated, a total of two reports will be submitted, one for the wastewater line borings and one for the lift stations. The first report will be limited to general discussion regarding the subsurface stratigraphy observed throughout the borings, boring location plan, log of borings and a summary of test results. We will furnish you with three bound copies and one unbound copy of our formal report for your use and distribution. The second report will include a narrative description of the field investigations including boring logs, laboratory test summaries, discussions regarding the various soil properties, including foundation design and construction criteria for the wet wells, adjacent CMU buildings and valve vaults. This information will include but not be limited to bearing capacity recommendations, shrink/swell estimations, floatation preventative measures for the wet well, backfill and bedding materials specifications, and lateral earth pressure design parameters. In addition, pavement design alternatives will be provided for each site. We will furnish you with three bound copies and one unbound copy of our formal report for your use and distribution. Estimated Cost: The total cost of our work associated with the Geotechnical Investigation as outlined above is estimated not to exceed $24.400.00 including all mobilizations, field drilling, sampling, monitor well installation and four monthly readings, laboratory testing, engineering analysis and report preparation. This cost is based on the attached Unit Price Fee Schedule. We will not exceed this estimate total unless the project work scope changes and unless written authorization is received. We will schedule the field activities upon your formal approval to proceed. Geo-chemical testing has been excluded from the above cost estimate. For an additional fee of $3,850.00, total sulfates and chlorides, soil-box electrical resistivity, and pH testing may be conducted in addition to the previously listed laboratory testing program. The results will be provided to you for your use. Our interpretation of these results will be limited to coorelations presented in the literature and our previous experience. This work effort does not include the design and/or selection of measures to limit corrosion. 61 YPG365\6131PI53 Copyright 2001 Kleinfelder. Inc. 3601 Manor Road . Austin, Texas 78723 .
