NOTE: GEOGRID ELEVATION TOLERANCE t .5' (ALL DIMENSIONS ARE IN FEET)
GENERAL NOTES
1) REFER TO CIVIL GRADING PLANS FOR WALL ALIGNMENTS AND ELEVATIONS.
2) REFER TO REINFORCING SCHEDULE FOR GEOGRID LENGTHS AND ELEVATIONS.
3) GEOGRID ELEVATION MEASURED FROM TOP OF CRUSHED ROCK LEVELING PAD.
4) GEOGRID LENGTH "L" MEASURED FROM BACK OF FACE UNIT_
5) GEOGRID SHALL BE INSTALLED BEHIND WALL WITH MACHINE DIRECTION (STRONGEST AXIS)
PERPENDICULAR TO WALL.
6) GEOGRID SHALL BE INSTALLED ON HORIZONTAL SURFACE OF COMPACTED STRUCTURAL FILL.
7) GEOGRID SHALL BE PULLED TIGHT BEHIND WALL. STAKE END OF GEOGRID AS REQUIRED TO MAINTAIN
TENSION BEFORE COVERING WITH STRUCTURAL FILL.
8) PROTECT GEOGRID FROM CONSTRUCTION DAMAGE PER MANUFACTURERS SPECIFICATIONS.
CONSTRUCTION EQUIPMENT SHALL NOT TRAVEL DIRECTLY ON GEOGRID. ANY GEOGRID THAT IS DAMAGED
SHALL BE REPLACED WITH NEW GEOGRID AT CONTRACTORS EXPENSE.
9) SEGMENTAL BLOCK WALL ASSEMBLY TO BE COMPLETED PER MANUFACTURERS SPECIFICATIONS.
10) STRUCTURAL FILL SHALL BE PLACED AND COMPACTED IN 12-IN LOOSE LIFTS TO 95% OF THE SOILS
MAXIMUM DRY DENSITY AS DETERMINED BY ASTM D-698. THE MOISTURE CONTENT OF THE MATERIAL
SHALL BE WITHIN 2% OF THE SOILS OPTIMUM AS DETERMINED BY THIS SAME STANDARD. STRUCTURAL FILL
IN REINFORCED ZONE SHALL BE GRANULAR MATERIAL WITH MAXIMUM AGGREGATE SIZE OF 31NCHES AND
A MAXIMUM SOILS FINES (LESS THAN #200 SIEVE) CONTENT OF 20 PERCENT.
11) HEAVY CONSTRUCTION EQUIPMENT SUCH AS VIBRATORY DRUM ROLLERS, LOADED DUMP TRUCKS,
FRONT-END LOADERS, ETC., SHALL NOT OPERATE WITHIN FIVE FEET OF BACK OF WALLS. STRUCTURAL
FILL PLACED IN THIS ZONE SHALL HAVE MAXIMUM LOOSE LIFT THICKNESS OF 12 INCHES AND SHALL BE
COMPACTED USING HAND OPERATED COMPACTION EQUIPMENT.
