7. TESTING FOR CONCRETE STRENGTH
The Manufacturer shall, at company expense, take at least eight repre-
sentative cylinders of each day's pour and test as follows: one at release,
two at seven days, two at 14 days, two at 28 days, and one spare. A copy
of the test reports shall be furnished to the Purchaser upon request.
7.1 Minimum Shipping Strength
Poles may not be shipped until the static concrete strength test has
achieved the 28-day value used in the design. An exception to this may
be taken only with prior approval of the Purchaser and only if the Manu-
facturer can produce statistical records showing a consistent gain in con-
crete strength over a predictable time period that would indicate that an
earlier shipping date would still result in the design strength being
achieved within the 28-day period.
8. INSPECTION AND QUALITY ASSURANCE
8.1 Inspection by Purchase
The Purchaser or a company-authorized representative shall have
access to the work at all times for inspection wherever the poles are
in preparation or progress. The Manufacturer shall provide proper
facilities for such access and inspection without additional cost to the
Purchaser.
All materials will be subject to jobsite inspection. To avoid delays and
complications, the Purchaser will make every effort to inspect the poles
upon delivery and notify the Manufacturer of any problems immediately.
Material may be rejected at the time of the fi rst inspection or at any time
defects are found during the progress of the erection or installation.
Inspection by the Purchaser or waiving of inspection shall not relieve
the Manufacturer of the responsibility for furnishing products that
conform to the requirements of this specifi cation.
8.2 Manufacturer's Quality Assurance Program
The Manufacturer shall have an active in-plant quality assurance
program and perform daily checks and tests on the products made. The
program shall cover the entire production process, including the delivery
of the product. A written record of these tests and inspections shall be
made at the Manufacturer's plant facility for the Purchaser's review. Each
pole manufactured shall have a unique identifi cation number that corre-
lates to a specifi c quality control inspection traveler and report.
