made, if desired, for observation before shipment from the place of
manufacture. CONTRACTOR must anticipate that possible delays may occur
due to the necessity of materials being inspected and accepted for use.

1.3 SUBSTANDARD WORK OR MATERIALS

A.

Any defective or substandard Work or materials furnished by CONTRACTOR
that is discovered before the final acceptance of the Work, as established by
ENGINEER, or during the subsequent guarantee period, shall be removed
immediately by CONTRACTOR even if it had been initially overlooked by
ENGINEER and recommended for payment. Equipment or materials
condemned or rejected by ENGINEER shall be tagged as such and shall be
immediately removed from the site by CONTRACTOR. Satisfactory Work or
materials shall be substituted by CONTRACTOR for that rejected.

ENGINEER may order tests on substandard or damaged Work, equipment, or
materials to determine the required functional capability for possible
acceptance, if there is no other reason for rejection. The cost of such tests shall
be borne solely by CONTRACTOR and the nature, extent, and supervision of the
tests will be as determined by ENGINEER. If the results of the tests indicate
that the required functional capability of the Work, equipment, or material is
not impaired, consistent with the final general appearance of same, then the
Work, equipment, or materials may be deemed acceptable. If the results of
such tests reveal that the required functional capability of the questionable
Work or materials has been impaired, then such Work or materials shall be
deemed substandard and shall be replaced by CONTRACTOR at no additional
cost to OWNER. CONTRACTOR may elect to replace the substandard Work or
material in lieu of performing the tests.

Schedule adjustments will not be made for correcting substandard or damaged
Work.
