Although the channel footprint has been dredged previously, crab traps may still be present. The Contractor shall take necessary precautions that he/she deems necessary in order to prevent damage to the dredge pump and reduce down time. Crab traps and all other non-natural debris encountered during dredging shall be disposed of by removal from the site. The costs of removal shall be included in the applicable unit price for dredging. Bidders shall take into consideration the possible presence of crab traps when preparing their bid and should consider making a Pre-Bid Site Visit, as stated in Section 01100, paragraph PRE-BID SITE VISIT.”

Houma Navigation Canal Terrebonne Bay and Cat Island Pass

Maintenance Dredging, #18.1, Terrebonne Parish, LA

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

Award will be made as a whole to one bidder, based on TOTAL WORK price for row “TOTAL 1 – ALTERNATIVE 1” or “TOTAL 2 – ALTERNATIVE 2”.

NOTE 1: The intent of the Government is to award “Alternative 1”. Due to limited availability of funds, final selection of Alternative to be awarded by the Government will be based on the Total Work price for row “TOTAL 1 - ALTERNATIVE 1” or “TOTAL 2 - ALTERNATIVE 2” and the Government availability of funds at the moment of award. The Alternative 1 will be selected for award if funds sufficient to make award of that work are available at the time of bid opening. If funds sufficient to make award of the Alternative 1 are not available at the time of bid opening, the Alternative 2 will be awarded, provided funds sufficient for award of such work are available. Bidders must bid on both alternatives. If the bidder omits both the unit price and the extended amounts for any of the items in the alternative 1 or alternative 2 sections, then the bid will be declared non-responsive.

Item Nos. 0002, 0003, and 0005 is subdivided into two 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 sub-items.

(End of Clause)

VARIATIONS IN ESTIMATED QUANTITIES - SUBDIVIDED ITEMS (UAI 5152.211-

9001 Mar 1995).

The Variations in Estimated Quantities Subdivided Items clause is applicable only in Item Nos. 0002, 0003, and 0005.

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

b. Where the actual quantity of work performed for Item Nos. 0002, 0003, and 0005 is less than 85% of the quantity of the first sub-item listed under such items, the Contractor will be paid at the contract unit price for that sub-item for the actual quantity of work performed and, in addition, an equitable adjustment in contract price shall be made in accordance with the clause FAR 52.211-18, Variation in Estimated Quantity .

c. If the quantity of work performed under Item Nos. 0002, 0003, and 0005 exceeds 115% or is less than 85% of the total estimated quantity of the sub-items under that item, and/or if the quantity of work performed under the second sub-item or any subsequent sub-item under Item No. NONE exceeds 115% or is less than 85% of the estimated quantity of any such sub-item, and if such variation causes 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 FAR 52.211-18, Variation in Estimated Quantity.
