�. B. Footings are to be constructed on undisturbed natural soil or engineered <br /> fill with a safe soil bearing value as indicated on the structural <br /> drawings. The soil conditions at the footing level must be verified by <br /> an independent laboratory before any concrete footing is placed. <br /> C. Backfill excavations as quickly as construction will permit. Place in <br /> eight (8") inch lifts and thoroughly compact. Grade backfill so that <br /> water cannot accumulate next to foundations. <br /> D. Place and compact a minimum of six inches of select granular fill under <br /> floor slabs, concrete paving, and sidewalks. <br /> END SECTION 02200 <br /> ` � <br /> 02200-4 <br /> 191/1/1006. 1 <br />
