In accordance with your request, we have prepared this rough grading report for the subject property. The report represents a summary of the observations and compaction testing of the fill placed on the proposed grading pad. Field testing and observations indicate the compaction of the soil was performed properly. The soil should perform satisfactorily for the expected usage. The included findings and recommendations have been derived in accordance with generally accepted professional principles and practices in the fields of soil mechanics and foundation engineering. This warranty is in lieu of all other warranties, either expressed or implied. The opportunity to be of continued services is sincerely appreciated. If you should have any questions or require further information, please contact me at your convenience. Respectfully submitted, ~---/2~..-- . 02- Gunvant Thakkar, RCE 52856 2-. . . INTRODUCTION In accordance with your request, tests have been performed on the fill placed on the rough graded residential pad. The excavation, fill placement, compaction and testing associated with this phase of the, grading was performed during February 22, 1999 through February 26, 1999. This report presents a summary of the observations and testing services provided. PROJECT DESCRIPTION The site will have a single family residence with attached garage constructed on it with associated landscaping and access drive. This structure could consist of a one or two story, wood framed residence founded on a continuous perimeter footings foundation system. GRADING PROCEDURES The observations and test results indicated that the grading was performed in the method consistent with the project specifications. All areas to receive fill were striped and cleared of vegetation and soft soil prior to placement of soil fill. Keying and benching into natural ground was completed in general compliance with the Uniform Building Code, as amended by Ordinance 93-04. The minimum acceptable degree of compaction content was 90 percent of the maximum density. , FIELD DENSITY TESTING Field density testing was performed in accordance with ASTM D1556-64 (Sand Cone Method) or D- 2937-71 (Drive Cylinder) test method, respectively. The results of the field density tests are presented in Table I of this report. The approximate location of the tests are shown on the Plot Plan, Plate 1. MAXIMUM DENSITY DETERMINATIONS Maximum density/optimum moisture determinations were made from representative samples of on- site soils used in the fill operations. The tests were performed in accordance with ASTM D1557-78 Method. .3 . . LIMITATIONS The findings and recommendations of this report were prepared in accordance with contemporary principles and practices in the field of geotechnical engineering. No other warranty or guarantee is eithen expressed or implied. Only a portion of the subsurface soils and conditions were evaluated or observed and the conclusions are based upon an interpretation of the soil conditions encountered in the field tests. Conclusions are also based on the assumption that these findings do not vary appreciably in the adjacent areas. However, minor variations may occur: should soil conditions significantly different be encountered in the future, an assessment of the impact on subsequent recommendations should be made. All future grading and fill placement should be performed under the inspection and testing of a registered civil engineer. SUMMARY Our description of grading and backfill operations, as well as observations and testing services, were limited to those,grading operations performed during February 22,1999 through February 26, 1999. The conclusions and recommendations contained herein have been based upon our observation and testing as noted. It is our opinion that the work performed in the areas denoted has generally been accomplished in accordance with Uniform Building Code, as amended by Ordinance 93-04. No conclusions or warranties are made for areas not tested or observed. Due to periodic site inspections and testing, footing excavations should be inspected by a registered civil engineer prior to' concrete placement to verify proper embedment entirely into competent soils. ./---- Sinceg!(y, , ~, / .:2?j:~.- \.- ;fEar;:;;., .".. .... ," ....: . ~.v"'"...Jt.;~,(;:'o.2.1 .
