DESCRIPTION

This work shall consist of furnishing and driving foundation
piles of the type and dimensions designated on the plans or in the
special provisions including cutting off or building up foundation
piles when required. This specification also covers providing test
piles and performing loading tests. Piling shall conform to and be
installed in accordance with these specifications, and at the
location, and to the elevation, penetration, and bearing capacity
shown on the plans or as directed by the Engineer.

Any improperly driven, broken, or otherwise defective pile shall
be corrected to the satisfaction of the Engineer by removal and
replacement, or the driving of an additional pile, at no extra
cost.

Except when test piles are required, the Contractor shall
furnish the piles in accordance with the dimensions shown on the
plans or special provisions. When test piles are required, the pile
lengths shown on the plans are for estimating purposes only and the
actual lengths to be furnished for production piles will be
determined by the Engineer after the test piles have been driven.
The lengths given in the Engineer's order list will include only
the lengths anticipated for use in the completed structure. The
Contractor shall, without added compensation, increase the lengths
shown or ordered to provide for fresh heading and for such
additional length as may be necessary to suit the method of
operation.
