BASIS OF AWARD
The basis of Award of this Contract shall be on the lowest total for the summation of Base Bid Schedule. In case of discrepancy between the unit price and the item cost set forth for a unit basis item, the unit price shall prevail and, shall be utilized as the basis for determining the lowest responsive, responsible bidder. However, if the amount set forth as a unit price is ambiguous, unintelligible or uncertain for any cause, or is omitted, or is the same amount as the entry in the “Item Cost” column, then the amount set forth in the “Item Cost” column for the item shall prevail and shall be divided by the estimated quantity for the item and the price thus obtained shall be the unit price. Final payment shall be determined by the Engineer from measured quantities of work performed based upon the unit price.
The Contractor shall include all costs for mobilization of equipment to perform all of the work required by the Bid Schedule. No additional monies will be paid for mobilization or demobilization of additional equipment required to perform the work.
The Bidder agrees that this Bid Form constitutes a firm offer to the City which cannot be withdrawn for the number of calendar days indicated in the Notice Inviting Bids from and after the bid opening, or until a Contract for the Work is fully executed by the City and a third party, whichever is earlier.
