shall be used until notice has been given by the Contracting Officer that
test results are satisfactory. In the event of failure, the cement may be
resampled and tested at the request of the Contractor and at the
Contractor's expense. The fill gate or gates of the sampled bin will be
sealed and kept sealed until shipment from the bin has been completed.
Sealing of the fill gate or gates and of conveyances used in shipment will
be done by or under the supervision of the Government. Conveyances will
not be accepted at the site of the work unless received with all seals
intact. If tested cement is rehandled at transfer points, the extra cost
of inspection will be at the Contractor's expense. The cost of testing
cement excess to project requirements will also be at the Contractor's
expense and will be deducted from payments due the Contractor at a rate of
[_____] dollars per test.
1.3.2.7
Nonprequalified Pozzolan Sources
Pozzolan, if not from a prequalified source, will be sampled at the source
or at the site of the work and will be stored in sealed bins pending
completion of acceptance tests. Pozzolan may be resampled at the site when
determined necessary. All sampling and testing will be performed by and at
the expense of the Government. Release for shipment and approval for use
will be based on compliance with 7-day lime-pozzolan strength requirements
and other physical, chemical, and uniformity requirements for which tests
can be completed by the time the 7-day lime-pozzolan strength test is
completed. Release for shipment and approval for use on this basis will be
contingent on continuing compliance with the other requirements of the
specifications. If test results of a bin fail, the contents may be
resampled and tested at the Contractor's expense. The Government will
supervise or perform the unsealing and resealing of bins and shipping
conveyances. If tested pozzolan is rehandled at transfer points, the extra
cost of inspection will be at the Contractor's expense. The cost of
testing excess pozzolan in excess of project requirements will be at the
Contractor's expense at a rate of [_____] dollars per test. The amount
will be deducted from payment to the Contractor.
1.3.2.8
Admixtures
The Contractor shall provide satisfactory facilities for ready procurement
of adequate test samples. All sampling and testing of an admixture will be
by and at the expense of the Government. Tests will be conducted on the
same materials which will be shipped to the project.

CONSTRUCTION TOLERANCES
**************************************************************************
NOTE: Delete any of the following tables that are
not applicable. Most projects will require several
tables to cover all parts of the structure.
**************************************************************************
The definitions of the terms used in the following tables shall be as
defined in ACI 117. Level and grade tolerance measurements of slabs shall
be made as soon as possible after finishing. When forms or shoring are
used, the measurements shall be made prior to removal. Tolerances are not
cumulative. The most restrictive tolerance controls. Tolerances shall not
extend the structures beyond legal boundaries. Except as specified
otherwise, plus tolerance increases the amount or dimension to which it
applies or raises a level alignment, and minus tolerance decreases the
amount or dimension to which it applied or lowers a level alignment. A
