throughout the profile. If a geotextile filter is present, the
reinforcement shall be laid out so that interference with the
geotextile is minimized.
d. Any reinforcement not placed with the machine direction as the
design reinforcement direction shall be identified on the shop drawings.
e. Reinforcement attached to the wall facing shall not combine geogrid
and geotextile, nor products from different manufacturers, within one
wall. The number of reinforcement products shall be limited to avoid
confusion in placement. For walls under 3.5 meters 12 feet high, all
reinforcement shall be the same grade and strength (i.e. design with
one reinforcement strength).

SUPPLIER QUALIFICATIONS
**************************************************************************
NOTE: The suggested text is recognized to be
somewhat vague. It limits situations were a
never-before-used product is proposed, or where a
product is proposed for use outside the limitations
(such as batter) listed in the manufacturer's
literature. The qualifications should be modified
for the project's degree of difficulty (e.g. walls
over 10 m height). Caution to avoid unreasonable
qualifications should be exercised if modifying.

[Suppliers of segmental retaining wall system components shall have
demonstrated experience in the supply of similar size and types of
segmental retaining walls on previous projects.]
1.8
MANUFACTURER'S
REPRESENTATIVE
**************************************************************************
NOTE: The geosynthetic manufacturers
representatives generally have assumed involvement
in construction; but that is not necessarily true in
all localities. The number of site visits expected
by the manufacturer's representative should be
quantified if known.
