TOTAL WORK: $

**The unit "JOB" as used in this Quote Schedule is synonymous with the term "Lump Sum" used elsewhere within these plans and specifications.

Award will be made as a whole to one quoter.

NOTE 1: Quoters shall furnish unit prices for each item listed in the Schedule requiring a unit price. If the quoter fails to insert a unit price in the appropriate blank for required item(s), but does furnish an extended total, or an estimated amount for such item(s), the Government shall deem the unit price to be the quotient obtained by dividing the extended amount for that line item by the quantity. IF A QUOTER OMITS BOTH THE UNIT PRICE

AND THE EXTENDED TOTAL OR ESTIMATED AMOUNT FOR ANY ITEM, ITS QUOTE

SHALL BE DECLARED NON-RESPONSIVE AND THEREFORE INELIGIBLE FOR

AWARD.

NOTE 2: Any quote may be rejected if the Contracting Officer determines in writing that it is unreasonable as to price. Unreasonableness of price includes not only total price of bid, but the price for individual line items as well. Any bid may be rejected if the prices for any line items or sub line items are materially unbalanced.

NOTE 3: THE NOTICE TO PROCEED (NTP): The successful quoter is advised that performance and payment bonds shall be submitted within five (5) calendar days after issuance of contract award. The NTP will be issued immediately after verification of acceptable performance and payment bonds. Within five (5) days after issuance of the NTP, the Contractor shall initiate a meeting to discuss the submittal process with the Area or Resident Engineer or his authorized representative. Physical work cannot start until the Accident Prevention Plan, Contractor Quality Control Plan, and other submittals which may be required, have been submitted and approved and all preliminary meetings called for under the contract, have been conducted.
