This proposal includes a description of the project, scope of work, estimated fee,Vnd project schedule. PROJECT DESCRIPTION The project consists of overlying the existing runway and extending the runway to the south. The existing runway consists of 10 inches of reinforced concrete pavement. A 200-foot long shoulder currently exist beyond the south end of the runway. We understood that this 200-foot shoulder will be removed and the runway expanded for a length of 500 feet. A new 200-foot long shoulder,will be constructed beyond the runway expansion. SCOPE OF WORK The geotechnical investigation performed for the referenced project will consist of field and - laboratory investigations, engineering analysis, and .a report prepared 6y a Registered. ProfessionalEngineer. Field investigation We understand that the field investigation will have to be performed at night between the hours of 10:00 p.m. and 6:00 a.m. We further understand that no special requirements will be necessary for accessing the runway area. •N•• 10610 Newkirk Street• Suite 202.

The test borings will be drilled to depths of 10 feet below existing grade. We plan to use Wo drilling rigs in order to complete the field work in one night. . Prior to drilling, the existing runway and shoulder will be cored using an B-inch diameter core barrel and a coring machine. The core samples will be measured for thickness and then given to the client. We anticipate that 18 areas will have to be cored (16 through the runway and 2 through the shoulder). Subsurace soil samples will be secured with thin walled tube and/or split spoon samples depending on soil type and consistency. Roc% encountered.in.the borings will be evaluated using the Texas Department of Transportation Penetrometer(TxDOT Cone).All samples will be properly logged, packaged• sealed, and placed in a core box for transportation to the laboratory. The test borings will be backfilled and the pavement patched upon drilling completion. Alliance Geotechnical Group assumes that we will have the right-of-entry and that the boring locations will be accessible to our conventional truck mounted drilling equipment. Should unusual soil conditions be encountered, we will call you with a recommendation and cost estimate to explore these unusual conditions. We understand Una l:underground utilities present in the subject area will be identified and mark by others prior to beginning the field work. Alliance Geotechnical Group cannot be responsible for damage to underground utility lines that are not identified before mobilization of drilling equipment to the site. ti Laboratory {nvestigation Laboratory tests will be conducted to classify the soil and to evaluate the volume change potential and strength of the soil and rock present at the site. Soil classification tests will consist of Atterberg limits (plasticity Index), moisture content, and dry unit weight. The strength of the soil will be measured using unconfined compression tests and estimated using hand penetrometer test. The volume change potential of the soils will be evaluated by swell tests. Lime series tests will be performed in order to determine the optimum amount of lime required to stabilize the subgrade in the expansion area, Laboratory CBR tests will be performed on representative soil samples obtained in the proposed runway extension area. Engineering Analyses Results of field and laboratory work will be presented in an engineering report. The report will , include the following, 1. Site reconnaissance, field coordination, boring marking; and utility clearan:e. - 2. Plan of borings, boring logs,water level observations, and laboratory test results. 3. Fill placement recommendations for the runway extension area. 4. Subgrade stabilization recommendations for the runway extension area. .. �i.n, � tea.>:•.a �r.•e>mac.. r -n'��r. - - APP. 12 '01 08:43 FP.
