(the usual alternative is to make a conservative
assumption).
**************************************************************************
All testing expenses shall be the Contractor's responsibility. Testing
shall be performed by a commercial testing laboratory selected by the
Contractor and approved by the Contracting Officer or performed by the
Contractor if approved by the Contracting Officer. The Contracting Officer
reserves the right to direct the location and select the material for
samples.

TEST DESIGNATION
Wide Width Strip
ASTM D 4595
[_____]
Tensile Strength
ASTM D 4595 shall be modified for geogrids considering recommendations in
GSI GRI GG6; and the tensile strength shall be expressed on a unit length
basis by substituting n*a for Ws, where:
Ws = specimen width, (mm inches)
n = number of ribs in the sample (must be a whole number)
a = nominal rib spacing for the product tested, (mm inches)
3.10
DRAINAGE PIPE
Drain pipe shall be placed as indicated on the drawings. Drain lines shall
be laid to true grades and alignment with a continuous fall in the
direction of flow. The interior of the pipe shall be kept clean from soil
and debris; and open ends shall be temporarily capped as necessary.
3.11
CONSTRUCTION TOLERANCES
**************************************************************************
NOTE: The suggested tolerances represent the
standard of practice. Tighter tolerances should be
specified with caution. Loosen horizontal and
vertical tolerance if acceptable. Plumbness and
alignment will limit bulging.
**************************************************************************
a. Horizontal: The top of wall shall be within [_____] [75 mm] [3
inches] of the plan location.
b. Vertical: The top of wall elevations shall be within [_____] [30
mm] [0.1 feet] above to [_____] [30 mm] [0.1 feet] below the prescribed
top of wall elevations shown on the drawings.
c. Plumbness and Alignment: The wall batter and alignment offset
measured as deviation from a straight edge shall be within plus or
minus [_____] [30 mm per 3 meter] [1.25 inches per 10 feet] section.
The batter measured from vertical shall be within [2] degrees of the
plan dimension.
d. Block Defects: The blocks will be accepted on the basis of
tolerances specified in ASTM C 1372.
