December 19, 2016 Buzz Oates Development LP Attention: Troy Estacio 8615 Elder Creek Road Sacramento, CA 95828 FOUNDATION INVESTIGATION MURPHY PARKWAY WAREHOUSE Murphy Parkway near D’Arcy Parkway Lathrop, California Job No. 146-618 INTRODUCTION Our firm has completed a Foundation Investigation for a warehouse proposed for construction east of Murphy Parkway in Lathrop. This report presents the results of the investigation. The purpose of this report is to provide data pertinent to earthwork construction, foundation design, floor support, and pavement design. Field exploration for this investigation has included the drilling of ten test borings to depths of ten to 20 feet below the existing site grade, and one boring to a depth of 50 feet. Undisturbed soil samples were obtained from the borings for classification and laboratory testing. Disturbed samples of the near surface soils also were obtained from proposed pavement areas. The test boring and sampling locations are shown on Plate 1, Plot Plan; logs of the test borings completed for this study are shown on Plates 2 through 16, Log of Boring. The nomenclature used to describe the soils on the logs is defined on Plate 17, Unified Soil Classification System. Moisture, density and unconfined compressive strength test data are presented on the logs at the depths of each sample tested. Two samples of the subsurface sandy soils were subjected to sieve analyses to provide information used in our liquefaction analyses; these test results are graphed on Plate 18, Grain Size Analyses. Near surface soil samples were subjected to direct shear tests to evaluate strength properties; these test results are tabulated on Plate 19, Direct Shear Data. Samples of anticipated pavement subgrade soils were subjected to resistance value tests to evaluate pavement subgrade properties; the test results are shown on Plates 20 and 21, Resistance Value Data. A sample of the subgrade soils was mixed with cement, remolded, and tested in unconfined compression to evaluate reactivity with the treatment chemical; these test results are tabulated on Plate 22, Treated Soil Compressive Strength Data. Two samples of the subsurface soils were submitted to an associate chemical laboratory for testing of corrosion properties; these test results are reproduced on Plates 23 and 24. The results of liquefaction analyses are depicted on Plates 25, Liquefaction Analysis. 3140 BEACON BLVD. -- WEST SACRAMENTO, CA 95691 -- TELEPHONE 916/371-0434 -- FAX 916/371-1809
