The Installation Contractor will direct any remedial work required to bring the
surface into compliance with the Specifications required for Geomembrane
installation. Upon satisfactory surface preparation, the Installation Contractor
and the CQA Consultant will issue a letter to OWNER indicating acceptance of
the subgrade.
E. The Geomembrane shall be placed over the prepared surfaces in a manner that
results in minimum handling. Any portion of Gomembrane damaged during
installation by any cause shall be removed or repaired at no additional cost to
OWNER.
F. Geomembrane panels to be installed on slopes shall be oriented such that
seams are parallel to the line of slope. The seams shall be terminated or
extended a minimum of 25 feet from the toe of slope.
G. Each Geomembrane panel shall be assigned a simple and logical identification
number or letter. In addition, the Installation Contractor shall record the roll
number, location, and date of installation of each panel placed. The panels
shall be marked by their identification number or letters, and shall be recorded
on the as-built drawings by the Installation Contractor. Upon completion of
the Work, the Installation Contractor shall submit as-built drawings with panel
identifications to the CQA Consultant.
H. The panel layout pattern will be decided upon prior to placement in a meeting
between OWNER, ENGINEER, CONTRACTOR, the CQA Consultant, and the
Installation Contractor. The panel overlap pattern should be similar to that
used for shingles, to facilitate the drainage of water. No more panels shall be
deployed during a single day than can be seamed or tack-welded together that
same day.
I. All deployed Geomembrane panels shall be protected from wind uplift by
placing suitable ballast that will not damage the Geomembrane during its
placement or removal.
J. All disturbed subgrade or other underlying material shall be repaired and
observed by the CQA Consultant prior to deploying Geomembrane panels.
K. Vehicle traffic shall not be allowed directly on Geomembrane panels.
Equipment shall not damage panels by handling, leakage, transporting across
panels, or any other means. Personnel working on or with Geomembrane
panels shall not wear shoes that may damage the panels.
L. |Geomembrane panels shall be deployed using methods that will not stretch,
crimp, abrade, or otherwise damage panels. Placement of panels shall employ
methods that limit wrinkles and differential wrinkles between adjacent panels.
