CRITICAL ITEMS SUMMARY
Geotechnical Engineer: Ensure a qualified
Geotechnical Engineer observes the pile
driving operations and is available to
answer questions that arise.
Ensure a qualified/experienced person
maintains the pile driving records
which includes the blow counts.
Check the Contractor's pile driver,
equipment, method of positioning
piles and proposed pile driving
Do not overdrive piles since they
are friction piles. If the Contractor
should accidentally overdrive a pile,
be sure to get the pile driving history
of that pile and have the Contractor
design the required buildup section in
accordance with the specs and forward
to the designers by courier as soon as
possible, advising the designers by
telephone or cable that the information
is on its way.
Underwharf Vaults: The underwharf vaults
are precast. Be sure that the Contractor
provides shop drawings for the precast
vault. The shop drawings should show
the lifting points and the lifting system.
Have the designers check the Contractor's
approved shop drawings. Be sure the vaults
are waterproofed inside and out and that
they are in the proper place before the pile
caps and deck are cast-in-place.
