B.20. COMPACTION OF SOIL BACKFILLS AND FILLS

A. Place backfill and fill soil materials in layers not more than 200 mm in loose depth for material compacted by heavy compaction equipment and not more than 100 mm in loose depth for material compacted by hand-operated tampers.

B. Place backfill and fill soil materials evenly on all sides of structures to required elevations and uniformly along the full length of each structure.

C. Compact soil materials to not less than the following percentages of maximum dry unit weight according to [ASTM D698] [ASTM D1557]:

1. Under structures, building slabs, steps, and pavements, scarify and recompact top 300 mm of existing subgrade and each layer of backfill or fill soil material at 95 percent.

2. Under walkways, scarify and recompact top 150 mm below subgrade and compact each layer of backfill or fill soil material at 95 percent.

3. Under turf or unpaved areas, scarify and recompact top 150 mm below subgrade and compact each layer of backfill or fill soil material at 92 percent.

4. For utility trenches, compact each layer of initial and final backfill soil material at 95 percent.

B.21. SUBSURFACE DRAINAGE

A. Subsurface Drain: Place subsurface drainage geotextile around perimeter of subdrainage trench. Place a 150-mm course of filter material on subsurface drainage geotextile to support subdrainage pipe. Encase subdrainage pipe in a minimum of 300 mm of filter material, placed in compacted layers 150 mm thick, and wrap in subsurface drainage geotextile, overlapping sides and ends at least 150 mm.

1. Compact each filter material layer with a minimum of two passes of a plate-type vibratory compactor.

B. Drainage Backfill: Place and compact filter material over subsurface drain, in width indicated, to within 300 mm of final subgrade, in compacted layers 150 mm thick. Overlay drainage backfills with one layer of subsurface drainage geotextile, overlapping sides and ends at least 150 mm.

1. Compact each filter material layer with a minimum of two passes of a plate-type vibratory compactor.

2. Place and compact impervious fill over drainage backfill in 150-mm thick compacted layers to final subgrade.

B.22. FIELD QUALITY CONTROL

A. Geotechnical Testing Agency: The Contractor will engage a qualified geotechnical engineering testing agency to perform field quality-control testing. Geotechnical Testing Agency must be from independent from Contractor and Contractor’s firm unless approved by the Project Director/COR.

B. Allow geotechnical testing agency to inspect and test subgrades and each fill or backfill layer. Proceed with subsequent earth moving only after test results for previously completed work comply with requirements.

C. Foundation Subgrade: At foundation subgrades, at least one test of each soil stratum will be performed to verify design bearing capacities. Subsequent verification and approval by the Geotechnical Testing Agency of other footing subgrades may be based on a visual comparison of subgrade with tested subgrade when approved by Project Director/COR.

D. Testing agency will test compaction of soils in place according to ASTM D1556, ASTM D2167, ASTM D2922, ASTM D2937, and ASTM D6938, as applicable. Note that if Contractor request approval to use an electromagnetic density gauge (EDG) according to ASTM D 7830 to assess soil compaction, prior approval should be received from Project Director/COR and a minimum of one sand cone (ASTM D 1556), or drive-cylinder (ASTM D 2937) compaction test shall be performed for every 20 EDG tests. Tests will be performed at the following locations and frequencies:

1. Paved and Building Footprint Areas: At subgrade and at each compacted fill and backfill layer, at least one test for every 186 sq. m or less of paved area or building footprint but in no case fewer than three tests.

2. Foundation Wall Backfill: At each compacted backfill layer, at least one test for every 30 m or less of wall length but no fewer than two tests.

3. Trench Backfill: At each compacted initial and final backfill layer, at least one test for every 46 m or less of trench length but no fewer than two tests.

E. When testing agency reports that subgrades, fills, or backfills have not achieved degree of compaction specified, scarify and moisten or aerate, or remove and replace soil materials to depth required; recompact and retest until specified compaction is obtained.

B.23. PROTECTION

A. Protecting Graded Areas: Protect newly graded areas from traffic, freezing, and erosion.

Keep free of trash and debris.

B. Repair and reestablish grades to specified tolerances where completed or partially completed surfaces become eroded, rutted, settled, or where they lose compaction due to subsequent construction operations or weather conditions.

1. Scarify or remove and replace soil material to depth as directed by Project Director/COR; reshape and recompact.

C. Where settling occurs before Project correction period elapses, remove finished surfacing, backfill with additional soil material, compact, and reconstruct surfacing.

2. Restore appearance, quality, and condition of finished surfacing to match adjacent work, and eliminate evidence of restoration to greatest extent possible.

B.24. DISPOSAL OF SURPLUS AND WASTE MATERIALS

A. Remove surplus satisfactory soil and waste materials, including unsatisfactory soil, trash, and debris, and legally dispose of them off Government's property.
