Footing Subgrade: At footing subgrades, at least one test of each soil stratum will be <br /> performed to verify design bearing capacities. Subsequent verification and approval of other <br /> footing subgrades may be based on a visual comparison of subgrade with tested subgrade <br /> when approved by Engineer. <br /> E. Testing agency will test compaction of soils in place according to ASTM D1556, ASTM D2167, <br /> ASTM D2937, and ASTM D6938, as applicable. Tests will be performed at the following <br /> locations and frequencies: <br /> 1. Paved and Building Slab Areas: At subgrade and at each compacted fill and backfill layer, <br /> at least one test for every 1000 sq. feet or less of paved area or building slab but in no <br /> case fewer than three tests. <br /> 2. Wall Backfill: At each compacted backfill layer, at least one test for every 50 feet or less <br /> of wall length but no fewer than two tests. <br /> 3. Trench Backfill: At each compacted initial and final backfill layer, at least one test for <br /> every 50 feet or less of trench length but no fewer than two tests. <br /> F. When testing agency reports that subgrades, fills, or backfills have not achieved degree of <br /> compaction specified, scarify and moisten or aerate, or remove and replace soil materials to <br /> depth required; recompact and retest until specified compaction is obtained. <br /> 3.19 PROTECTION <br /> A. Protecting Graded Areas: Protect newly graded areas from traffic, freezing, and erosion. Keep <br /> free of trash and debris. <br /> B. Repair and reestablish grades to specified tolerances where completed or partially completed <br /> surfaces become eroded, rutted, settled, or where they lose compaction due to subsequent <br /> construction operations or weather conditions. <br /> 1. Scarify or remove and replace soil material to depth as directed by Engineer; reshape <br /> and recompact. <br /> C. Where settling occurs before Project correction period elapses, remove finished surfacing, <br /> backfill with additional soil material, compact, and reconstruct surfacing. <br /> 1. Restore appearance, quality, and condition of finished surfacing to match adjacent <br /> work, and eliminate evidence of restoration to greatest extent possible. <br /> 3.20 DISPOSAL OF SURPLUS AND WASTE MATERIALS <br /> A. Remove surplus satisfactory soil and waste materials, including unsatisfactory soil, trash, and <br /> debris, and legally dispose of them off Owner's property. <br /> B. Transport surplus satisfactory soil to designated storage areas on Owner's property. Stockpile <br /> or spread soil as directed by Engineer. <br /> Orange County Solid Waste Drainage Repairs DAA 2200365/TRC 017055.0000.0000 <br /> Drainage Repair Project November 2023 <br /> Orange County, NC 312000-12/13 <br />
