' <br /> 1. Acceptance of construction below finish grade including perimeter insulation where , <br /> applicable. <br /> 2. Surveying Iocations of underground utilities for record documents. <br /> 3. Testing,inspecting,and approval of underground utili#ies. � <br /> 4. Concrete form work removal. <br /> 5. Removal of trash and debris from excavation. <br /> B. Place az►d compact initial backfill of satisfactory soit material or subbase material,free of ' <br /> particles lazger than 1 inch,to a height of 12 inches over the utili#y pipe or conduit <br /> C. Coordinate backfilling with utilities testing. � <br /> D. Fil!voids with approved backf iti materials as shoring and bracing,and sheeting is removed. <br /> E. Place and compact final bacl�ill of sa.tisfactory soil material to final subgrade. ' <br /> F. Install wacning tape directly above utilities,l2 inches below finished grade,except 6 inches <br /> below subgrade under pavements and slabs. � <br /> G. Drainage Bacl�'ill:Place and compact drainage backfill of filtering material over subsurface <br /> drain,in width indicated,to within i2 inches of finai subgrade. Overlay drainage backfill <br /> with one layer of filter fabric, overlapping edges at Ieast 6 inches. ' <br /> 3.9 FILL <br /> A. Preparation: Remove vegetation, topsoil, debris, wet, and unsatisfactory soil materials, , <br /> obstructions,and deleteriaus materials from ground surface prior to placing fills. <br /> 1. Plow strip,or break up sloped surfaces steeper than 1 vertical to 4 horizontal so fill � <br /> material will bond with existing surface. <br /> A. Place fiIl material in layers to required elevations for each location listed below. , <br /> 1. Under grass,use satisfactory excavated or borrow soil material. <br /> 2. Under walks and pavements,use subbase or base material,or satisfactory excavated � <br /> or borrow soil ma#erial. <br /> 3. Under steps and ramps,use subbase material. <br /> 4. Under building slabs in all occupied areas,use special gas permeable material(for <br /> Radan protection). , <br /> 3.10 MOTSTURE C4NTROL <br /> A.
