Goldkamp Senior Civil Engineer Design and Construction Division City of Chula Vista 276 Fourth Avenue Chula Vista, ,California 92010 Subject: Proposal for Soils Investigation F Street Basin Drainage Improvements W.O. AO-034 Dear Mr. Go Idkamp: We appreciate the opportunity to present a proposal for a soils investigation to be conducted for the above drainage improvements. The purpose of this investigation will be to determine the ccndition of existing sub grade soils and their suitability to support these structures, and to determine the stability of the existing soil, so that it may be determined whether or not vertical cuts of 5 to 8 feet may be expected to stand during trenching, or if additional sroring is needed. In addi tion, we propose to investigate the soils be low the footin~ of two existing buildings adjacent to the proposed work, by hand excavations, to determine depths of existing footings. Also, the hand pits will be excavated to 3 feet below the invert in order to ta~e undisturbed sample'-for laboratory tests. It is understood that the City of Chula Vista will take protographs of all existing bui Idings and structures near the storm drain route as a record before the project starts. Also, we will inspect and record any existing cracks or differential movements already existing in the buildings adjacent to the storm drain, in the event that it is later contended that the storm drain work resulted in any damage to the buildings. It is proposed to hand excavate four test pits in the area of the two buildings, to depths of approximately 10 feet below the ground surface and to 3 feet below the invert of the proposed pipe. In addition, it is proposed to drill four borings, 24 inches in diameter, along the route of the proposed pipe and drainage channel with a truck-mounted rotary bucket-type auger to 10 to 15 feet deep. It is assumed that the City of Chula Vista has obtained permission for access for sampling at various points along the proposed route. We will arrange to check for the existence of any underground utilities within the areas of the hand pits and test borings so that no utilities will be damaged. The borings will be drilled, 24 inches in diameter, using a truck-mounted rotary bucket-type drill rig. The soils enccuntered in the borings will be logged by our field engineer and undisturbed samples will be taken at intervals of 2 to 4 feet, where possibl e, in the gravel-free various soil types to the depths of exploration. The samples wilt be obtained by driving a special ~_ \\~ c,/\ Iv\r. Kenneth J. Goldkamp Proposal for Soils Investigation -2- February 25, 1985 steel sampling tube, lined with 12 one-inch high by 2.42 inch inside diameter brass cylindrical liners into the soils ahead of drilling. The samples will be extracted from the borings with the soil still confined within the brass liners. A six-inch section of the center portion of each sample will be taken for laboratory tests in close-fitting waterproof containers in order to retain the field moisture until completion of the tests. loose bulk samples will also be obtained of representative fill and/or backfill soils for laboratory testing. Laboratory tests will be performed on all of the undisturbed samples to determine the field moisture and density. Direct shear tests will be conducted on saturated and drained samples under several normal loads to determine the angle of internal friction and cohesion. These data will be used in stability calculations and active, passive pressures and bearing value determinations. Also, load-consolidation tests will be performed on representative samples of the soils. The data from these tests will be used to determine the allowable supporting capacity of the soils and active and passive pressures if needed for underpinning or shoring design. In order to determine the maximum dry densities and optimum moisture contents of any fill soils, the representative samples will be tested by the A.S.T .M. D 1557-78 method of compaction which uses 25 blows of a 10 pound rammer falling from a height of 18 inches on each of 5 layers in a 4-inch diameter 1/30 cubic foot compaction cylinder. The findings In the field investigation, test data, conclusions and recommendations will be presented in a final report. The engineering charges for this investigation will be based upon our standard hourly rates plus the cost of drilling.
