Aggregate shall not be stored directly on ground unless a sacrificial layer
is left undisturbed. Reinforcing bars and accessories shall be stored
above the ground on platforms, skids or other supports. Other materials
shall be stored in such a manner as to avoid contamination and
deterioration. Admixtures which have been in storage at the project site
for longer than 6 months or which have been subjected to freezing shall not
be used unless retested and proven to meet the specified requirements.
Materials shall be capable of being accurately identified after bundles or
containers are opened.
1.11
GOVERNMENT ASSURANCE INSPECTION AND TESTING
Day-to day inspection and testing shall be the responsibility of the
Contractor Quality Control (CQC) staff. However, representatives of the
Contracting Officer can and will inspect construction as considered
appropriate and will monitor operations of the Contractor's CQC staff.
Government inspection or testing will not relieve the Contractor of any of
his CQC responsibilities.
1.11.1
Materials
The Government will sample and test aggregates, cementitious materials,
other materials, and concrete to determine compliance with the
specifications as considered appropriate. The Contractor shall provide
facilities and labor as may be necessary for procurement of representative
test samples. Samples of aggregates will be obtained at the point of
batching in accordance with ASTM D 75. Other materials will be sampled
from storage at the jobsite or from other locations as considered
appropriate. Samples may be placed in storage for later testing when
appropriate.
1.11.2
Fresh Concrete
Fresh concrete will be sampled as delivered in accordance with ASTM C 172
and tested in accordance with these specifications, as considered necessary.
1.11.3
Tests on hardened concrete will be performed by the Government when such
tests are considered necessary.
1.11.4
Inspection
Concrete operations may be tested and inspected by the Government as the
project progresses. Failure to detect defective work or material will not
prevent rejection later when a defect is discovered nor will it obligate
the Government for final acceptance.
