Planned for construction is a Iight industrial tilt-up building. The structures are to be supported on conventional continuous and pad footings with slab-on-grade concrete floors. ){o Foundation Soils Investigation was prepared by this firn. PIease refer to the letter of responsibility dated August 20. 1974. FIELD TESTING AND OBSERVATIONS As part of the clearing operation' all vegetation and debris l{ere renoved from the site. Tree roots rere renoved by hand to a depth of 6 feet. As preparation for receiving fi11r the natural ground was undercut to a depth of 5-l/2 to 7 feet to remove a black corupressible peat, uhich rias removed fron the site, The botton was then scarified to a depth of 6 inches, compacted and tested. The soil was then considered suitable to suP- port the fill and the proposeC structures. The fill was placed in lifts of 6 inch thickness and compacted by neans of a 6 x 6 sheepsfoot roller and by means of wheelrolling with loaded scrapers. The north footing was undercut below the existing storn drain. The footing should I Job No. 74-l2Z'2 Page 2 be placed to a depth allowing for the dissipation of footing loads, having no effect on the storm drain. The depth of the footing will be determined by the factor of a 45 degree angle fron the bottom of the footing. This angle should provide for dissipation of loads into undistured soi1s. Footing designs will be furnished by Floyd weaver Structural Engineers, our reconmendations are included in this report. The required moisture was supplied by a fire hose. The filI material consisted of both on-site and inported soils. The on-site material consistcd of a sandy silty clay vhile the import nay by classified as a redish brown sand. The density of the soil was deterrnined in accordance with A.S.T.M. Test Methods D-1556-64T and D-2937-71. The test results r{ere conpared to the naximun density as determined in the laboratory in accordance with A.S.T.l'1. Test ltletho<I D-l557-70T rnodified to use three layers in lieu of five. The results of the tests are presented on the attached "Tab1e of Test Results" with their approxirnate locations shown on attached plot p 1an.

As a result, footings nay be designed for an allowable bearing value of 4,400 pounds per square foot for continuous footing, provided they are placed to a ninimum width and depth of 18 inches and 5r100 pounds for isolated footings. An increase on 1/3 of the above bearing value for short duration load- ing is perurissible. S€a Plate rAr for tlrea.r t€8t roaults. Concrete Slab Construction The ground water table was not reached in any of the grading and, as a consequence, ground water is not expected to be a problenr on this project. The use of rock base under floor slabs rnay be onitted. Linits of Certification This report covers the grading perforned between the dates of August 13, 1974 and August 24, !974. Gene ral The grading performed on this site was done in an acceptable manner and in conformance with the Building Code and the City of Santa Ana and in confornance with the stand- ards specified by Federal Housing Administration. The results of testing indicate that the fill has been conpacted a Job No. 74-LZ2-Z Page 4 ao at least 90 percent except at the botton of the undercut xnere 85 percent of maximum density rras required. This report is issueJ with the understanding that it is the responsibility of the ohrter or his representative to ensure that tlle information and re conrnendati ons contained herein are called to the attention of the Project Architect and Engineer and are incorporated into the plans and specifications and that necessary steps are taken to see that the contractors and subcontractors carry out such re conmendat ions .
