Reason for Change:
Stiff soil conditions were encountered while driving the hollow steel sections for the concrete
piles. The ultimate bearing resistance for the piles was achieved. However, the driven depth of
the hollow steel sections did not reach the minimum tip elevations specified in the contract
plans. As a result, the adjusted final quantity of the bid item FURNISHING CONC. PILING (24"
DIA) is at 53% of the original Bid quantity. Pursuant to Section 1-04.6, the Contractor is entitled
to an equitable adjustment since the adjusted final quantity is less than 75% of the original Bid
quantity.
