CONTRACT AWARD WILL BE MADE UNTIL APPROPRIATE FUNDS ARE MADE

AVAILABLE IN ACCORDANCE WITH AFARS 5101.602-2.

(b) THIS PROCUREMENT IS UNRESTRICTED.

(c) All technical inquiries and questions relating to this solicitation are to be submitted via Bidder Inquiry in ProjNet at http://www.projnet.org/projnet. See Section 00100 Entitled

“TECHNICAL INQUIRIES AND QUESTIONS”.

(d) Bidders shall furnish unit prices for all items listed on the schedule of bid items which require unit prices. If the bidder fails to insert a unit price in the appropriate blank for required items, but does furnish an extended total or an estimated amount for such items, the Government will deem his unit price to be the quotient obtained by dividing the extended estimated amount for that line item by the quantity. IF THE

BIDDER OMITS BOTH THE UNIT PRICE AND THE EXTENDED ESTIMATED

AMOUNT FOR ANY ITEM, HIS BID WILL BE DECLARED NONRESPONSIVE.

(e) All quantities shown on the BIDDING SCHEDULE are estimated quantities except when the unit of measure is shown as "lump sum", "job" or "each".

(f) If a bid or modification to a bid based on unit price is submitted which provides for a lump sum adjustment to the total estimated cost, the application of the lump sum adjustment to the unit price in the schedule must be stated. If it is not stated, the bidder agrees that the lump sum adjustment shall be applied on a pro rata basis to the unit price in the Bid Schedule.

(g) Item Nos. 0001, 0002, 0003, 0004, 0005, 0006, 0007, 0008, 0015, 0016, 0017, 0018, 0019, 0020, 0021, 0022, 0023, 0024, 0025, 0026, 0027, 0028, 0029, 0030 are subdivided bid items.

Each of these items has been subdivided into two sub-items. The Contractor shall bid on only one of these eight subdivided bid items for the base contract period and shall bid on only one of the eight subdivided bid items for each bid option. A bid for the work shall include a bid for each of the sub-items for either Item 0001, 0002, 0003, 0004, 0005, 0006, 0007, OR 0008, and 0015, 0016, 0017, 0018, 0019, 0020, 0021, OR 0022, and 0023, 0024, 0025, 0026, 0027, 0028, 0029, OR 0030. Bidders should refer to Section 00 08 00.00 09 SPECIAL CONTRACT http://www.projnet.org/projnet

REQUIREMENTS, paragraph entitled "VARIATIONS IN ESTIMATED QUANTITIES--SUBDIVIDED ITEMS" before preparing their bid for these items.

(h) All extensions of the unit price shown will be subject to verification by the Government. In case of variation between the unit price and the extension, the unit price will be considered to be the bid.

(i) Award will be made as a whole to the lowest responsive, responsible bidder as may be in the best interest of the Government.

(j) Lack of registration in the SAM database will make an offeror ineligible for award. SEE CONTRACT CLAUSE 52.204-7

ENTITLED, "SYSTEM FOR AWARD MANAGEMENT".

(k)The SF1442, Bidding Schedule, Plant Characteristic Sheets, and Section 00600 (Representations and Certifications) must be accurately completed and returned with your bid or it may be rejected as nonresponsive.

(l) The contract will be 365 days from the date of award, unless it becomes necessary to terminate the contract earlier.

(m)DEMOBILIZATION: Only ONE demobilization will be paid.

(n) Line items 0015-0030 are optional line items that may be exercised if funding becomes available but will not extend the period of performance of this contract.

(o) Except for the subdivided bid items as noted in paragraph above, Bidders shall include a bid price for all items in the base period and all items in the option period. Failure to provide bid prices for all payment items will render the bid non-responsive.

(p) If a contractor submits a bid on this solicitation to use a dredge that is currently under another contract then the contractor may not be eligible for award unless they submit a detailed plan demonstrating how they plan to successfully complete multiple contracts using one dredge. Any plan submitted must be accepted and approved by USACE prior to award.

Payment will be based on Item Nos. 0001AA, 0002AA, 0003AA, 0004AA, 0005AA, 0006AA, 0007AA, OR 0008AA, 0015AA, 0016AA, 0017AA, 0018AA, 0019AA, 0020AA, 0021AA, 0022AA, 0023AA, 0024AA, 0025AA, 0026AA, 0027AA, 0028AA, 0029AA, OR

0030AA as applicable, until the sum of the Effective Time (100 percent payment) and 80 percent of the noneffective time (80 percent payment) is greater than the "A" item hours. Payment items 0001AB, 0002AB, 0003AB, 0004AB, 0005AB, 0006AB, 0007AB, OR 0008AB, 0015AB, 0016AB, 0017AB, 0018AB, 0019AB, 0020AB, 0021AB, 0022AB, 0023AB, 0024AB, 0025AB, 0026AB, 0027AB, 0028AB, 0029AB, OR 0030AB as applicable, will be the basis for payment for all time greater than the "A" item hours.

a. Effective Time.

The following will be considered effective time and will be paid at the applicable contract price per hour:

(1) Pump Time

Actual time of dredging when the dredge is under operation, with the cutterhead moving material, and such material is being passed through the pipe line.

(2) Passing Vessels

Time lost while making openings in floating discharge pipe lines or swinging to one side of the channel to allow vessels to pass.

The Contractor shall make such openings upon signal of any vessel or craft desiring to pass.

(3) Washing Operations

Actual time spent in washing operations and repositioning underwater pipeline when discharge is used to flush underwater material and debris from areas that cannot be dredged. Such areas are gate recesses and sills at lock chambers, and underneath docks

SECTION 35 20 23.00 09 Page 3 or piers.

b. Noneffective Time

The following will be considered noneffective time and will be paid at 80 percent of the applicable contract price per hour:

(1) Prepare to Move, Move Same Job, Locking Through

Actual time lost up to, but not more than four (4) hours for each of the following: preparing to move from one job to another, preparing the dredge for pumping upon arrival at a new job, or upon startup at the first work site or start-up after suspension, and locking the dredge and attendant plant through a lock. Actual time lost up to, but not more than 6 1/2 hours for moving from one location to another on the same job. Moves of less than 20 miles will be considered "same job" provided the dredge is moved at least 3 mph and is fully crewed. In instances where more than 1000 feet of floating pipeline must be assembled prior to start of work at a new site or disassembled to move, up to two (2) additional hours will be allowed in preparing to dredge or preparing to move for each 1000 feet of additional pipeline.

(2) Move Anchors, Handle Pipe, Change Wires

Actual time lost up to two hours due to moving or changing swing anchors or attempting to retrieve a stuck anchor, or making changes in discharge lines such as adding or removing floating pipeline or shoreline pipe as may be necessary. Actual time lost up to four hours to connect floating pipeline to shoreline.

(3) Clean Pump, Wash Pipeline

Actual time lost due to removal of logs, driftwood, rocks, etc., from the pump, pipeline and cutterhead or removal of drift from the pontoon line, and necessary time lost due to washing out pipe line before handling. Also, actual time lost up to, but not more than four hours due to dredge shutdowns authorized by the Contracting Officer to replace the pump impeller with either different diameter impeller or an impeller with a different number of vanes, or installing or replacing a knife in the pump. Also, actual time lost up to but not more than one hour due to dredge shutdowns authorized by the Contracting Officer to change the dredge cutterhead to a cutterhead of a different type. The intent of payment for delays authorized by the Contracting Officer to permit the Contractor to change pump impellers, install knives, and dredge cutterheads is to obtain the greatest efficiency of operations under changing conditions, such as varying material, length of line, etc. Payment will not be made under this paragraph for replacing worn out impellers and/or dredge cutterheads that have lost their efficiency because of wear.

(4) Prepare for Suspension

When operations are suspended under the provisions of Section 01 00 00.00 09 GENERAL CONTRACT REQUIREMENTS, paragraph DURATION OF CONTRACT, subparagraph "b", payment will continue at eighty

(80) percent of the contract price per hour for a period not to exceed 4 hours to allow the Contractor to prepare dredge, SECTION 35 20 23.00 09 Page 4 pipeline, and attendant plant for towing or for lay-up at a nearby site. The dredge and attendant plant should be tied up in such a manner and location so as not to be a hindrance to navigation.

Lay-up in the immediate vicinity of the Locks and Dams on the Red River is a hazard to navigation. The Contractor will be paid up to 8 hours of non-effective (80 percent) time for moving the dredge and attendant plant to the nearest location which is not a hazard to navigation.

(5) Short Term Standby

Actual time lost due to dredge standby time at the direction of the Contracting Officer is to provide for situations, caused by conditions beyond the Contractor's control and which usually delay operations only a few hours (but could be several days). Examples of this type condition are as follows: Upon arrival at the job site the dredge is unable to begin dredging because another dredge or vessel is temporarily in the way. Insufficient notice was given for constructing a shoreline and the dredge must wait for completion of the shoreline. This paragraph does not cover the temporary suspensions provided for under Section 01 00 00.00 09 GENERAL CONTRACT REQUIREMENTS, paragraph DURATION OF CONTRACT.

(6) Weather

Actual time lost due to inclement weather (fog, wind, thunderstorms, etc.), not to exceed 4 hours unless approved by the Contracting Officer, which causes operation of the plant to be unsafe or impractical while on an assignment or while moving between assignments. Lost time caused by inclement weather prohibiting transfer from personnel to or from the dredge does not apply and will be considered a nonpayment item.

1.1.2 Lost Time

Payment will not be made for the following:

a. Lay time upon completion of an assignment or lay time after arrival at location of a new assignment when such time is not incurred at the direction of the Contracting Officer; or when through negligence of the Contractor the necessary equipment is not available or in operating condition at the new assignment, or for time during suspension of operations, as provided in Section 01 00 00.00 09 GENERAL CONTRACT REQUIREMENTS, paragraph DURATION OF CONTRACT, subparagraph "c".

b. Time lost due to shutdown for the repair or the replacement of worn out or unserviceable equipment including wire rope and time lost due to pulling a pipeline together when the joints open, replacing damaged shoreline pipe or pontoons, unless shoreline pipe is damaged by caving bank or pontoons are damaged by drift through no fault or negligence of the Contractor.

c. Time during which the dredge is engaged in removing misplaced material and dredging time lost due to removal of obstructions as required in Section 00 80 00.00 09 SPECIAL CONTRACT REQUIREMENTS, paragraph MISPLACED MATERIALS.

d. Time during which the dredge is engaged in dredging for others, time being computed from time the dredge shuts down until the dredge is

SECTION 35 20 23.00 09 Page 5 back in position and material is being passed through the pipeline.

e. Time lost due to shutdown ordered by the Contracting Officer due to nonconformance to EM 385-1-1. (See Clause ACCIDENT PREVENTION of the Contract Clauses and safety requirements of these specifications.)

f. Time lost due to insufficient crew size and the inability to perform efficiently simultaneous dredging operations and on-shore disposal operations as determined by the Contracting Officer or his representative. (See paragraph CREW.)

g. Time lost in priming main dredge pump that is in excess of five (5) minutes.

h. Time that is in excess of any of the maximum times set forth above under paragraph LEASE TIME, subparagraph NONEFFECTIVE TIME.

i. Lost time caused by inclement weather prohibiting transfer from personnel to or from the dredge.

j. When the dredge is shut down for any of the reasons as set forth above, the ensuing time shall remain under that classification until the cause of the shutdown has been removed and no claim shall be allowed for other work performed during that time unless the Contracting Officer orders the dredge and attendant plant to move to a new location.

1.1.3 Mobilization (PAYMENT ITEM 0009)

a. All costs connected with the mobilization of all of the Contractor's dredging plant and equipment will be paid for at the contract job price. One hundred percent (100 percent) of the contract job price for mobilization (PAYMENT ITEM 0009) will be paid to the Contractor upon completion of his mobilization at the work site. Only one mobilization will be paid under this contract.

b. In the event the Contracting Officer considers that the amount in Payment Item 0009, Mobilization, does not bear a reasonable relation to the cost of the work in this contract, the Contracting Officer may require the Contractor to produce cost data to justify this portion of his bid. Failure to justify such price to the satisfaction of the Contracting Officer will result in payment of the actual mobilization costs, as determined by the Contracting Officer at the completion of mobilization. The remainder of this item will be paid in the final payment under this contract.

c. Payments for mobilization of the dredging plant and equipment at a point of delivery other than the one specified in paragraph FIRST WORK LOCATION will be determined and made as follows:

(1) For the purpose of determining payments, the Contractor's location of dredging plant will be that stated as the site of inspection indicated on the bid form.

(2) Payments will be subject to a decrease or increase depending on whether the new point of delivery is nearer or farther, to the Contractor's location of dredging plant, than the location specified in paragraph FIRST WORK LOCATION.

SECTION 35 20 23.00 09 Page 6

(3) The adjustment will be applied at the contract unit price for "Miles Moved Upstream" or "Miles Moved Downstream," as stated in paragraph MOVING BETWEEN ASSIGNMENTS, below.

1.1.4 Demobilization (PAYMENT ITEMS 0010)

Only ONE demobilization will be paid. All costs connected with the demobilization of all of the Contractor's dredging plant and equipment will be paid for at the contract job price. One hundred (100) percent of the contract job price for demobilization (PAYMENT ITEMS 0010) will be paid to the Contractor upon expiration of the contract period and may be included in the final payment. Suspension of work by the Government during the Contract period will not constitute demobilization.

1.1.5 Suspension

The Contractor will be suspended after completion of all directed work during the contract year. The Contractor will remain in suspension status until the end of the contract year or until remobilized. The Contractor can be suspended at any time at the Contracting Officer's discretion due to reasons such as river conditions or funding issues.
