TECHNICAL SPECIFICATIONS
2. CONTRACTOR shall ensure that each geomembrane MANUFACTURER that supplies
materials to this project has an internal product quality control program that meets
SPECIFICATIONS.
3. During manufacturing of the geomembrane, samples of geomembrane shall be removed for
laboratory testing to ensure compliance with this SPECIFICATION. Conformance sampling and
testing will be performed in accordance with the Construction Quality Assurance Plan.
4. CONTRACTOR shall assure that the geomembrane is delivered to the site at least 10 calendar
days prior to installation. CONTRACTOR will provide required Quality Control information 10
calendar days prior to geosynthetics being delivered to PSES Pipe Rack Liner Extension Project
and on delivery of geosynthetics to the project.
5. Geomembrane rolls that do not meet the requirements of this SPECIFICATION will be rejected.
CONTRACTOR shall replace the rejected material with new material that conforms to the
SPECIFICATION requirements, at no additional cost to CC &V.
6. CONTRACTOR shall ensure that all personnel performing geomembrane- seaming operations are
performed by qualified technicians and that all seams pass seaming tests (see Part 3 (Execution) of
this SPECIFICATION). MANAGER reserves the right to reject any welding technician whose
performance is unsatisfactory.
7. INSTALLER'S superintendent and QC inspector shall attend the pre- construction meeting.
D. Field Samples
1. Geomembrane sampling and testing shall be conducted in accordance with the project
SPECIFICATIONS for the following:
a. Trial seam testing (Section 3.7 (D) of this SPECIFICATION)
b. Destructive seam testing (Section 3.9 of this SPECIFICATION)
2. CONTRACTOR shall maintain on -site a minimum of one spare operable tensiometer and
provide documentation indicating that all tensiometers used at the project were calibrated within
60 days prior to the tensiometer arriving on -site for testing field samples.
E. In order to prevent wind- damaged geomembranes from being placed, the following quality assurance
procedures shall be followed:
1. CONTRACTOR shall perform its Work and utilize sufficient ballast as necessary to prevent
wind uplift of the geomembrane panels.
2. If wind damage should occur, CERTIFYING ENGINEER shall determine if the geomembrane
shall be repaired or replaced. Wind damage to the geomembrane will include wrinkles, creases,
and tears, as determined by CERTIFYING ENGINEER.
3. Repair or replacement of the wind - damaged geomembrane shall be completed by
CONTRACTOR at no additional cost to CC &V.
4. As determined by MANAGER and CERTIFYING ENGINEER, the geomembrane panel may
be rejected at no cost to CC &V.
