FILL SPECIFICATIONS:
1. THE AREA TO BE FILLED SHALL BE PREPARED BY STRIPPING ALL EXISTING
TOPSOIL,UNSUITABLE MATERIAL, VEGETATION AND ANY ORGANIC MATERIAL,
THE GEOTECH ENGINEER SHALL INSPECT THE SITE AFTER PREPARATION
AND PRIOR TO FILL PLACEMENT.
2. THE GENERAL FILL SHOULD CONSIST OF THE FOLLOWING:
• A GRANULAR FILL FREE OF ORGANIC DEBRIS.
• BE PLACED AT OR NEAR THE OPTIMUM MOISTURE CONTENT SUCH
THAT IT CAN BE PLACED AND COMPACTED TO THE FOLLOWING PER-
CENTAGE OF THE MAXIMUM DRY DENSITY AS DETERMINED BY ASTM
D 1557.
95% - UNDER BUILDINGS AND PAVEMENTS AND WITHIN A 45
DEGREE SLOPE FROM BUILDING FOUNDATIONS.
90% REMAINING AREAS (YARDS AND LANDSCAPING AREAS)
• THE FIRST TWO FEET OF FILL PLACED OVER THE PREPARED
SUBGRADE SHOULD CONSIST OF A GRANULAR FILL WITH A MAXIMUM
OF 7.5% FINES PASSING THE #200 SIEVE. THIS LAYER SHOULD BE
CONTINUOUS AND EXTEND FROM THE BASE OF THE SLOPE TO THE
TOE OF THE NEWLY PLACED FILL.
3 FILL SHALL BE SPREAD EVENLY AND COMPACTED USING A VIBRATORY OR
SHEEP'S FOOT DRUM ROLLER
4. COMPACTION TESTS SHALL BE TAKEN DURING THE FILL PLACEMENT AT
THE DIRECTION OF THE GEOTECH ENGINEER AND LIFTS FAILING THE MIN.
COMPACTION SHALL BE RE -CONDITIONED (OR REMOVED) AND RE -COM-

EXPIRES
NOTES:
1. Reinforcenienl shall consist of a geogrid oquivalont to or oxcooding
Tensar UX1400HS. The geogrid shall conform to the minimum physical
requirements as indicated below. Prior to deploying the geogrid
reinforcement, the Contractor shall submit to the Engineer
a manufacturer's certificate of compliance.
The geogrid reinforcement shall be free from defects or damage.
If the geogrid is stored on site, the Contractor shall take measures
to protect it from damage, keep it free from dust and dirt, and
cover it with an opaque plastic sheet to prevent degradation from
ultra -violet light.
MINIMUM PHYSICAL PROPERTY REQUIREMENTS:
Ultimate Strength (unfactored). . . . . 4,570 Ibs/ft (GRI-GGI guidelines)
LTDS, well graded Sand & Gravel . . .1 ,700 Ibs/ft (GRI-GGI guidelines)
2. The reinforcement shall form horizontally continuous layers. Except
where a second layer of grid is required at the return wall face, no
overlaps or seams shall be oriented parallel to the face of the wall.
The Contractor may join the reinforcement by overlapping it a minimum
of 18-inches such that the seams are oriented perpendicular to the
face of the wall. The Contractor shall ensure that the geogrid is
deployed so that the geogrid strength is in the direction perpendicular
to the face of the wall and meets the specified minimum physical properties.
3. The contractor shall use falsework at the face of the wall to I
provide temporary support during the placement of each lift.
4. Structural fill shall be compacted to at least 95 percent of the
Maximum Modified Proctor density (ASTM D-1557). Structural fill
shall meet the gradation requirements listed in these notes.
5. Heavy compaction equipment shall remain at least two (2)
feet from the face of the wall. Structural fill placed within
three feet of the face of the wall shall be compacted firmly
using a minimum of two passes with light compaction
equipment. No vehicles shall operate directly on the reinforcement.
A minimum of six -inches of fill shall be placed on the
reinforcement before equipment may operate on it.
6. Drain gravel Shall consist of clean gravel and shall meet the gradation
requirements listed in these notes.

7. A geotextile fabric shall be placed under drain
gravel as shown.
The geotextile shall consist of a nonwoven, polyester or
polyethylene fiiter fabric with a minimum flow rate of 120 gpm/ft2
(ASTM D-4491), and a minimum Grab Tensile
strength of 120 Ibs
as measured by ASTM D 4632.
8. Golder Associates shall inspect the condition
of foundation to determine
suitability and to provide recommendations if
improvement is necessary.
