The material to be removed within the required dimensions specified consists of shoaling that has occurred since the channel was last dredged and insitu material. Sand, silt, clay, shell, logs, stumps, snags, debris, and other obstructions may be encountered. Bidders are expected to examine the site of the work and, after investigation, decide for themselves the character of the materials, The Contractor shall note the following dredging jobs previously performed:

Location Date Design Width Slopes

Dredged Elevation Dimensions Depth (ft-MLG)

Tchefuncte River 02 Dec 2017 (-)10.0' MLG 125' 1V:2H Bar Channel

*Note: Contractor shall note the presence of stumps and woody debris common along the shoreline of Lake Pontchartrain. Although the channel footprint has been dredged previously, woody debris may have been buried in the dredge template during high water events in the channel and movement within the lake during storm events. If option work is exercised, the Contractor should be aware the option reach was not dredged last contract (s). Contractors should estimate production for this option reach as a new cut with virgin material. Consideration of stumps is also required for disposal operations.

Disposal operations will require movement around and over stumps. Stumps, woody debris and all other debris removed during dredging/disposal operations shall be disposed of in accordance with paragraph entitled DISPOSAL OF NON-REGULATED DEBRIS AND OTHER WASTE of Section 01 57 20.01 12 ENVIRONMENTAL PROTECTION, except that stumps and woody debris may be placed within the disposal area. Dredging of access into the disposal areas for disposal of stumps and woody debris is not allowed. Contractor shall make precautions necessary to prevent damage to the dredge pump (screening).”

* Denotes a change from previous Bidding Schedule

Award will be made as a whole to one bidder.

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.

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

00010-4 ED 26-009

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 5: 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 not obligate the Government to exercise the option(s).

*NOTE 6: OPTION WORK ITEM: This provision pertains to Bid Item(s) 0003 and 0004.

The Government may require the delivery of, in whole or part, the Option Items. The Government may exercise the Option Items by written notice to the contractor at any point between Notice to Proceed and contract completion. If the Government activates an Option Item(s), the activation will occur while the Contractor’s plant is within the limits of work. 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 a non-responsive bid.

*NOTE 7: TIME ADJUSTMENT IN THE EVENT OF OPTIONAL WORK. In the event that Optional Work Item 0004 Dredging – OW is exercised under the terms of this contract, the time required for completion of the contract will be increased by 20 calendar days beyond the original duration of 56 calendar days established for the Base Work items specified in Section 00 73 00 SUPPLEMENTARY CONDITIONS, entitled

COMMENCEMENT, PROSECUTION, AND COMPLETION OF WORK.

NOTE 8: RAPID VENDOR PAYMENT. Web based instructions for the submission of invoices may be found at the following website:
