in excess of the limits specified above, shall be removed and replaced in
conformance with paragraph REPAIR, REMOVAL, REPLACEMENT OF NEWLY
CONSTRUCTED SLABS. [In pavement areas given a wire comb or tined texture,
areas exceeding 2 square meters 25 square feet that have been corrected by
diamond grinding shall be retextured by transverse grooving using an
approved grooving machine of standard manufacture. The grooves shall be 3
mm 1/8 inch deep by 6 mm 1/4 inch wide on 50 mm 2 inch centers and shall be
carried into, and tapered to zero depth within the non-corrected surface,
or shall match any existing grooves in the adjacent pavement.] All areas
in which diamond grinding has been performed will be subject to the
thickness tolerances specified in paragraph: Thickness. Any diamond
grinding performed on individual slabs with excessive deficiencies shall be
performed at the Contractor's own decision without entitlement to
additional compensation if eventual removal of the slab is required.
1.6
ACCEPTABILITY OF WORK
The materials and the pavement itself will be accepted on the basis of
tests made by the Contractor. The Government may, at its discretion, make
check tests to validate the results of the Contractor's testing. If the
results of the Contractor tests vary by less than 2.0 percent of the
Government's test results, the results of the Contractor's tests will be
used. If the results of the Government and Contractor tests vary by 2.0
percent or more, but less than 4.0 percent, the average of the two will be
considered the value to be used. If these vary by 4.0 percent or more,
each sampling and testing procedure shall be carefully evaluated and both
the Government and the Contractor shall take another series of tests on
duplicate samples of material. If these vary by 4.0 percent or more, the
results of the tests made by the Government shall be used and the
Government will continue check testing of this item on a continuous basis
until the two sets of tests agree within less than 4.0 percent on a regular
basis. Testing performed by the Government will in no way at any time
relieve the Contractor from the specified testing requirements.
1.7
PRECONSTRUCTION TESTING OF MATERIALS
**************************************************************************
NOTE: Designer must edit this paragraph and
following subparagraphs as appropriate.
For Design
Build Contracts the testing shall be performed by
the Contractor utilizing an approved petrographer
and commercial testing laboratory. Delete any
subparagraphs which are not applicable. Fill in
blanks as appropriate.
**************************************************************************
All sampling and testing shall be performed by, and at the expense of, the
Contractor, using an approved commercial laboratory or, for cementitious
materials and chemical admixtures, a laboratory maintained by the
manufacturer of the material. No material shall be used until notice of
acceptance has been given. The Contractor shall not be entitled to any
additional payment or extension of time because of delays caused by
sampling and testing additional materials, necessitated by failure of any
materials. Additional tests may be performed by the Government at the
discretion of the Contracting Officer; such Government testing will not
relieve the Contractor of any testing responsibilities.
