Award will be made as a whole to one bidder.

NOTE 1: Any bid 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 (See FAR 14.404-2).

NOTE 2: THE NOTICE TO PROCEED (NTP): The successful bidder is advised that performance and payment bonds shall be submitted in accordance with the time frame in block 12B of SF 1442. The NTP will be issued immediately after verification of acceptable performance and payment bonds. Within seven (7) 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 Program, 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.

NOTE 3: OPTIONAL WORK ITEMS. The Governent may require the delivery of the numbered line item(s), identified in the schedule as OPTIONAL WORK items, in the quantities and priceses stated in the schedule. The Contracting Officer may exercise the OPTIONAL WORK Items by written notice to the Contractor. Bidders shall bid on all items including optional items (see “Evaluation of Options” FAR 52.217-5). Failure to bid on all items will result in non-responsive bid.

NOTE 4: EVALUATION OF OPTIONS (FAR 52.217-5 JUL 1990). Except when it is determined in accordance with FAR 17.206(b) not to be in the Government’s best interests, the Government will evaluate offers for award purposes by adding the total price for all options to the total price for the basic requirement. Evaluation of options will nto obligate the Government to exercise the option(s).

**If an option is to be exercised at the time of the contract award in accordance with FAR 17.208, FAR clause 52.217-4 shall be used in palce of FAR clause 52.217-5.

NOTE 5: TIME ADJUSTEMENT IN THE EVENT OF THE EXERCISE OF OPTIONAL

WORK. In the event that OPTION WORK (Items 0010 through 0018) are exercised under the terms of the contract, an additional 305 calendar days will be added to the contract time. The Government will decide whether or not to exercise the option items within 300 calendar days after notice to proceed.
