unit price per unit length, which price shall include all items incidental
to furnishing and driving the piles including mobilization and
demobilization; [jetting]; [spudding]; [predrilling]; [shoes and] collars
where necessary; redriving uplifted piles; cutting off piles at the cutoff
grade line; 300 mm one foot broomed and removed from each driven pile;
treatment of the pile head exclusive of any capping; and additional 1.5 m 5
feet in furnished length for any test pile not driven beyond estimated pile
length; and retapping of piles.
**************************************************************************
NOTE: Regarding the text and table below, for unit
pricing situations, enter the tip to cutoff pile
length in the three blank spaces provided. Use tip
to cutoff lengths 300 mm one foot less than standard
ordering lengths, to allow for a 300 mm one foot
broomed end.
**************************************************************************
Payment for piles driven in lengths, as required, up to and including
[_____] meters feet in place below the cutoff elevation, will be at the
basic contract unit price bid. Payment for piles driven in lengths, as
required, greater than [_____] meters feet below the cutoff elevation will
be made at an adjusted unit price. Obtain the adjusted unit price by
multiplying the basic contract unit price bid by the applicable factor
shown in the table below.
**************************************************************************
NOTE: Use the following adjustment factors to
establish unit price factors for piles which are
driven in lengths longer than the tip to cut-off
lengths specified. Use a base factor of 1.00 for
the tip to cutoff length specified for the project.
or other lengths of piles, adjust the base factor by
adding (or subtracting) the cumulative total of the
adjustment factors listed below (i.e., to adjust the
factor from a 10 m 34 foot pile with the butt
circumference specified to a 13.5 m 44 foot pile
with the butt circumference specified, subtract 0.08
from 1.00).
