� <br /> � . � <br /> � . . <br /> 3.07 FIELD QUALITY CONTROL <br /> � Quality Control Testin� DurinR Construction: Allow testing service to inspect and <br /> approve subgrades and fill layers before further construction work is performed. <br /> Perform field density tests in accordance with ASTM D 1556 (sand cone method) or <br /> t ASTM D 2167 (rubber balloon method), as applicable. <br /> FootinR Sub�rade:. For each strata of soil on which footings will be placed, conduct <br /> Iat least one test to verify required design beacing capacities. Subsequent . <br /> verification and approval of each footing subgrade� may be based on a visual <br /> ' comparison of each subgrade with related tested strata, when acceptable to <br /> � L� � � <br /> Paved Areas and BuildinA Siab Sub�rade: Make at least one field density test of <br /> ' subgrade for every 2000 sq. ft. of paved area or building slab, but in no case less <br /> than 3 tests. In each compacted fill layer, make one field density test for every <br /> 2000 sq. ft. of overlaying building slab or paved area, but in no case less than 3 <br /> tests. <br /> � Foundation Wall Backfill: Take at least 2 field density tests, at locations and <br /> elevations as directed. <br /> tTrenches: Take at least one test per 100 lineal feet of depth in all trench areas. <br /> If in opinion of Lp�� based on testing service reports and inspection, <br /> � subgrade or fills wnicn nave been place are below specified density, provide additional <br /> compaction and testing at no additional expense. <br /> � 3.08 MAINTENANCE: � <br /> Protection of Graded Areas: Protect newly graded areas from traffic and erosion. Keep <br /> free of trash and debris. <br /> � Repair and re-establish grades in settled, eroded, and rutted areas to specified <br /> tolerances. <br /> ' Reconditioning Compacted Areas: Where completed compacted areas are disturbed by <br /> subsequent construction operations or adverse weather, scarify surface, re-shape, and <br /> compact to required density prior to further construction. <br /> � Settlin : Where settling is measurable or observable at excavated areas during general <br /> _� <br /> project warranty period, remove surface (pavement, lawn or other finish), add backfill <br /> ' material, compact, and replace surface treatment. Restore appearance, quality, and <br /> condition of surface or finish to match adjacent wock, and eliminate evidence of <br /> restoration to greatest extent possible. <br /> � 3.09 DISPOSAL OF EXCESS AND WASTE MATERIALS: <br /> Removal to Designated Areas on Owner's Property: <br /> � EARTHWORK 02200 - 9 <br /> 1 <br />
