SUBGRADE AND EACH LAYER OF BACKFILL OR FILL SOIL MATERIAL AT 100 PERCENT.
1. RETAINING WALLS WILL OVER 4' TALL REQUIRE A SEPARATE PERMIT AND INSPECTION.
1.
UNDER WALKWAYS, SCARIFY AND RECOMPACT TOP 6 INCHES (150 MM) BELOW SUBGRADE AND COMPACT EACH LAYER OF
BACKFILL OR FILL SOIL MATERIAL AT 95 PERCENT.
2. ALL STORM WATER CATCH BASINS, INLETS, MANHOLES, ETC. SHALL BE PERMANENTLY LABELED AS "NO DUMPING,
DRAINS TO RIVER" AND INCLUDE A FISH SYMBOL.
2.
UNDER TURF OR UNPAVED AREAS, SCARIFY AND RECOMPACT TOP 6 INCHES (150 MM) BELOW SUBGRADE AND COMPACT
EACH LAYER OF BACKFILL OR FILL SOIL MATERIAL AT 85 PERCENT.
1.1 SOIL FILL (GEOTECH REPORT SHALL TAKE PRECEDENCE OVER THIS SPECIFICATION IF EXISTS.)
3.
FOR UTILITY TRENCHES, COMPACT EACH LAYER OF INITIAL AND FINAL BACKFILL SOIL MATERIAL AT 95 PERCENT.
A. PLOW, SCARIFY, BENCH, OR BREAK UP SLOPED SURFACES STEEPER THAN 1 VERTICAL TO 4 HORIZONTAL SO FILL
MATERIAL WILL BOND WITH EXISTING MATERIAL.
1.4
GRADING
B. PLACE AND COMPACT FILL MATERIAL IN LAYERS TO REQUIRED ELEVATIONS AS FOLLOWS:
A.
GENERAL: UNIFORMLY GRADE AREAS TO A SMOOTH SURFACE, FREE OF IRREGULAR SURFACE CHANGES. COMPLY WITH
COMPACTION REQUIREMENTS AND GRADE TO CROSS SECTIONS, LINES, AND ELEVATIONS INDICATED.
1. UNDER GRASS AND PLANTED AREAS, USE SATISFACTORY SOIL MATERIAL.
1.
PROVIDE A SMOOTH TRANSITION BETWEEN ADJACENT EXISTING GRADES AND NEW GRADES.
2. UNDER WALKS AND PAVEMENTS, USE SATISFACTORY SOIL MATERIAL.
EX. STORM STRUCTURE
2.
CUT OUT SOFT SPOTS, FILL LOW SPOTS, AND TRIM HIGH SPOTS TO COMPLY WITH REQUIRED SURFACE TOLERANCES.
RIM: 845.9
3. UNDER STEPS AND RAMPS, USE ENGINEERED FILL.
INV IN & OUT: 836.8
B.
SITE ROUGH GRADING: SLOPE GRADES TO DIRECT WATER AWAY FROM BUILDINGS AND TO PREVENT PONDING. FINISH
4. UNDER BUILDING SLABS, USE ENGINEERED FILL.
SUBGRADES TO REQUIRED ELEVATIONS WITHIN THE FOLLOWING TOLERANCES:
5. UNDER FOOTINGS AND FOUNDATIONS, USE ENGINEERED FILL.
1.
TURF OR UNPAVED AREAS: PLUS OR MINUS 1 INCH (25 MM).
C. PLACE SOIL FILL ON SUBGRADES FREE OF MUD, FROST, SNOW, OR ICE.
2.
WALKS: PLUS OR MINUS 1 INCH (25 MM).
\
1.2 SOIL MOISTURE CONTROL
3.
PAVEMENTS: PLUS OR MINUS 1/2INCH (13 MM).
REVISE PERCENTAGES IN THIS ARTICLE ACCORDING TO GEOTECHNICAL ENGINEER'S WRITTEN RECOMMENDATIONS.
C.
GRADING INSIDE BUILDING LINES: FINISH SUBGRADE TO A TOLERANCE OF 1 /2 INCH (13 MM) WHEN TESTED WITH A 10-FOOT
UNIFORMLY MOISTEN OR AERATE SUBGRADE AND EACH SUBSEQUENT FILL OR BACKFILL SOIL LAYER BEFORE
(3-M) STRAIGHTEDGE.

AND INSPECTIONS.
2. REMOVE AND REPLACE, OR SCARIFY AND AIR DRY, OTHERWISE SATISFACTORY SOIL MATERIAL THAT EXCEEDS OPTIMUM
B.
ALLOW TESTING AGENCY TO INSPECT AND TEST SUBGRADES AND EACH FILL OR BACKFILL LAYER. PROCEED WITH
MOISTURE CONTENT BY 2 PERCENT AND IS TOO WET TO COMPACT TO SPECIFIED DRY UNIT WEIGHT.
SUBSEQUENT EARTH MOVING ONLY AFTER TEST RESULTS FOR PREVIOUSLY COMPLETED WORK COMPLY WITH REQUIREMENTS.
_--------- - \
1.3 COMPACTION OF SOIL BACKFILLS AND FILLS
C.
FOOTING SUBGRADE: AT FOOTING SUBGRADES, AT LEAST ONE TEST OF EACH SOIL STRATUM WILL BE PERFORMED TO VERIFY
DESIGN BEARING CAPACITIES. SUBSEQUENT VERIFICATION AND APPROVAL OF OTHER FOOTING SUBGRADES MAY BE BASED
\
ON A VISUAL COMPARISON OF SUBGRADE WITH TESTED SUBGRADE WHEN APPROVED BY ARCHITECT.
A. PLACE BACKFILL AND FILL SOIL MATERIALS IN LAYERS NOT MORE THAN 8 INCHES (200 MM) IN LOOSE DEPTH FOR
MATERIAL COMPACTED BY HEAVY COMPACTION EQUIPMENT, AND NOT MORE THAN 4 INCHES (100 MM) IN LOOSE
D.
TESTING AGENCY WILL TEST COMPACTION OF SOILS IN PLACE ACCORDING TO ASTM D 1556, ASTM D 2167, ASTM D 2922,
\
DEPTH FOR MATERIAL COMPACTED BY HAND -OPERATED TAMPERS.
AND ASTM D 2937, AS APPLICABLE. TESTS WILL BE PERFORMED AT THE FOLLOWING LOCATIONS AND FREQUENCIES:
B. PLACE BACKFILL AND FILL SOIL MATERIALS EVENLY ON ALL SIDES OF STRUCTURES TO REQUIRED ELEVATIONS, AND
E.
PAVED AND BUILDING SLAB AREAS: AT SUBGRADE AND AT EACH COMPACTED FILL AND BACKFILL LAYER, AT LEAST ONE
UNIFORMLY ALONG THE FULL LENGTH OF EACH STRUCTURE.
TEST FOR EVERY 2000 SQ. FT. (186 SQ. M) OR LESS OF PAVED AREA OR BUILDING SLAB, BUT IN NO CASE FEWER THAN THREE
____-- -----
TESTS.
--------- ------
C. COMPACT SOIL MATERIALS TO NOT LESS THAN THE FOLLOWING PERCENTAGES OF MAXIMUM DRY UNIT WEIGHT
ACCORDING TO ASTM D 698:
4.
FOUNDATION WALL BACKFILL: AT EACH COMPACTED BACKFILL LAYER, AT LEAST ONE TEST FOR EVERY 100 FEET (30 M) OR
LESS OF WALL LENGTH, BUT NO FEWER THAN TWO TESTS.
5.
TRENCH BACKFILL: AT EACH COMPACTED INITIAL AND FINAL BACKFILL LAYER, AT LEAST ONE TEST FOR EVERY 150 FEET (46 M)
NOTE:
OR LESS OF TRENCH LENGTH, BUT NO FEWER THAN TWO TESTS.
NO WETLANDS ARE PRESENT ON THIS SITE.
6.
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.
