<br />NOVEMBER 22, 2004 <br />PAGE 5 OF 10 <br /> <br />30. Prior to the placement of fill or foundations within the <br />building area, the site should be prepared in accordance with <br />the recommendations presented in the Site Preparation Section <br />of the Geotechnical Investigation Report prepared by T.E.L.A. <br />in April of 2003. Fill should be spread in 6 to 8 inch lifts <br />and should be moisture conditioned and compacted in accordance <br />with the recommendations presented in the Site Preparation <br />section. All undocumented fill or disturbed soils within the <br />building areas should be removed and compacted under <br />observation and testing of a representative of T.E.L.A. <br /> <br />31. The exposed subgrade and/or excavation bottom should be <br />observed and approved by a representative of T.E.L.A. for <br />conformance with the intent of the recommendations presented <br />in the geotechnical report and prior to any further processing <br />or fill placement. <br /> <br />32. On-site inorganic granular soils that are free of debris or <br />contamination are considered suitable for placement as <br />compacted fill. A representative of T.E.L.A. shall provide <br />guidance for acceptability and placement of on-site clay fill <br />materials. <br /> <br />33. Observation and field tests shall be performed during grading <br />by a representative of T.E.L.A. in order to assist the <br />contractor in obtaining the proper moisture content and <br />required degree of compaction. Where less than the required <br />degree if compaction indicated, additional compactive effort <br />any necessary adjustments in the moisture content of the soil <br />should be made to obtain the required compaction. <br /> <br />34. To evaluate the presence of satisfactory materials at design <br />elevations, footing excavations should be observed to be clean <br />of loosened soil and debris before placing steel or concrete <br />and probed for soft areas. If soft or loose soils or <br />unsatisfactory materials are encountered, these materials <br />should be removed and replaced with compacted fill. <br /> <br />35. Wherever, in the opinion of a representative of T.E.L.A, as <br />unsatisfactory condition is being created in any area, whether <br />by cutting or filling, then the work should not proceed in <br />that area until the condition has been corrected. <br /> <br />75C-125 <br />
