NOTE 1: The unit “JOB” as used in this Bidding Schedule is synonymous with the term “Lump Sum” used elsewhere within these plans and specifications.

00010-4 ED 20-024

NOTE 2: Bidders shall furnish unit prices for each item listed in the Schedule requiring a unit price. If the bidder 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 BIDDER OMITS BOTH THE UNIT PRICE

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

BE DECLARED NON-RESPONSIVE AND THEREFORE INELIGIBLE FOR AWARD.

NOTE 3: 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 subline items are materially unbalanced (See FAR 14.404-2, Rejection of Individual Bids).

NOTE 4: 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 after Notice of Award. The NTP will be issued immediately after verification of acceptable performance and payment bonds. Within 24 hours 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.

NOTE 5: OPTIONAL WORK ITEM. The Government may require the delivery of the numbered line item(s), identified in the schedule as Optional Work, in the quantity (total or partial quantity) and price stated in the schedule. The Contracting Officer may exercise all or part of the Optional Work by written notice to the Contractor. Bidders shall bid on all items including the Optional Work item (see "Evaluation of Options" FAR 52.217-5). Failure to bid on all items will result in a non-responsive bid.

NOTE 6: 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 this basic requirement. Evaluation of options will not obligate the Government to exercise the option(s).

NOTE 7: The quantity shown in Item 0002, 0003, 0009 and 0010 is for evaluation purposes only; payment for this item will be based on the actual quantity used and it shall be excluded from the clause FAR 52.211-18, “VARIATIONS IN ESTIMATED QUANTITIES”.

NOTE 8: TIME ADJUSTMENT IN THE EVENT OF THE EXERCISE OF OPTION WORK.

No time will be added to the contract duration for exercising Option Work Items 0008, 0009 and 0010. Items 0006 and 0007 if exercised will include an additional 20 calendar days to the original contract duration established for the BASE WORK items specified in the Contract Clause entitled “COMMENCEMENT, PROSECUTION, AND COMPLETION OF

WORK (FAR 52-211-10 – APR 1984)”.

NOTE 9: RAPID VENDOR PAYMENT: Web based instructions for the submission of invoices;

http:/www2.mvn.usace.army.mil/ebs/rapid_vendor_payment.asp http://www2.mvn.usace.army.mil/ebs/rapid_vendor_payment.asp

00010-5 ED 20-024

EVALUATION OF SUBDIVIDED ITEMS (Dec 2019 - AFARS 5152.211-9000).

Item Nos. 0004 and 0007 are subdivided into two (2) or more estimated quantities and are to be separately priced. The Government will evaluate each of these items on the basis of total price of its subline items.

(End of Clause)

VARIATIONS IN ESTIMATED QUANTITIES - SUBLINE ITEMS (Dec 2019 –

AFARS 5152.211-9001).

The variations in estimated quantities clause is applicable only to Item Nos. 0004 and 0007.

a. Variation from the estimated quantity in the actual work performed under any second or subsequent subline item or elimination of all work under such a second or subsequent subline item will not be the basis for an adjustment in contract unit price.

b. Where the actual quantity of work performed for Item Nos. 0004 and 0007 is less than 85% of the quantity of the first subline item listed under such item, the Contractor will be paid at the contract unit price for that subline item for the actual quantity of work performed and, in addition, an equitable adjustment shall be made in accordance with the clause Federal Acquisition Regulation (FAR) 52.211-18, VARIATION IN ESTIMATED QUANTITY.

c. If the quantity of work performed under Item Nos. 0004 and 0007 exceeds 115% or is less than 85% of the total estimated quantity of the subline item under that item and/or if the quantity of the work performed under the second subline item or any subsequent subline item under in Nos. NONE exceeds 115% or is less than 85% of the estimated quantity of any such subline item, and if such variation cause an increase or a decrease in the time required for performance of this contract the contract completion time will be adjusted in accordance with the clause
