C.
Allow 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.
D.
Testing agency will test compaction of soils in place according to ASTM D 1556, ASTM D 2167,
ASTM D 2922, and ASTM D 2937, as applicable. Tests will be performed at the following
locations and frequencies:
E.
3.18
1.
Paved and Building Slab Areas: At subgrade and at each compacted fill and backfill
layer, at least one test for every 2000 sq. ft. or less of paved area or building slab, but in
no case fewer than three tests.
2.
Foundation Wall Backfill: At each compacted backfill layer, at least one test for
every 100 feet 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 150 feet or less of trench length, but no fewer than two tests.
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.
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.
C.
Where settling occurs before Project correction period elapses, remove finished surfacing,
backfill with additional soil material, compact, and reconstruct surfacing.
1.
3.19
A.
Scarify or remove and replace soil material to depth as directed by Architect; reshape
and recompact.
Restore appearance, quality, and condition of finished surfacing to match adjacent work,
and eliminate evidence of restoration to greatest extent possible.
DISPOSAL OF SURPLUS AND WASTE MATERIALS
Remove surplus satisfactory soil and waste materials, including unsatisfactory soil, trash, and
debris, and legally dispose of them off Owner's property, unless otherwise directed by Owner.
