BIDDING SCHEDULE

NOTES

1. PRODUCTION INCENTIVE PAYMENT

(a) The government will pay an incentive of $1.00 for each cubic yard per hour of production for dredging rates that surpass or exceed a target rate of 500 cubic yards per hour for the inland waterway assignments on the BWT and Alabama River Systems and the Tennessee Tombigbee Waterway TTWW. There is no incentive payment for Costal projects or work for others. The incentive will be calculated based on the average rate of dredge material removed in cubic yards per hour at each dredging assignment or shoal location. Cubic yard rates calculated above the target rate of 500 CY/HR will then be multiplied times the number of actual 100% PAYTIME hrs. earned at each dredging assignment to determine the actual incentive payment amount earned; (Cy/Hr above Incentive = Measured Production Rate (cy/hr) – 500 cy/hr; Incentive Payment ($) = Cy/Hr above Incentive x 100% Hours x $1/cy). This amount will be paid in addition to the regular 100% PAYTIME rate in bid item 1. The government will also require that the contractor maintain a minimum production rate of 100 CY/Hr. while in the 100% PAYTIME pay status for each individual assignment. In the event that the minimum production is not met, a decrease or deduction of $1.00 for each cubic yard per hour below the minimum will be made for each assignment. The deduction will be taken from the regular 100% PAYTIME rate in bid item 1.

(b) Incentive yardage calculations for the Black Warrior/Tombigbee River System and the Alabama River System will be based on government performed before and after dredged hydrographic sweep surveys using Ross Labs multi-transducer sweep survey vessels and HYPACK hydrographic software to collect and edit the data. Incentive yardage calculations for the Tennessee Tombigbee Waterway will be based on government performed before and after dredged hydrographic surveys. Those surveys will be collected with either single-beam, multi-transducer, and/or multi-beam surveying equipment. HYPACK hydrographic software will be used for data collection, post processing and volume calculations.

The HYPACK program will be used to calculate the actual cubic yards removed using the two surface method comparing the before dredging bottom surface to the after dredging bottom surface for materials removed for the assigned dredging limits. The incentive payment will only be made for quantities removed, within these limits, but only for materials not exceeding the depth parameters stated in Section 1000, Paragraph 7.1.1., entitled: REQUIRED DREDGING.

(c) Where conditions such as high water or other unforeseen circumstances prevent the successful performance of the govt. hydrographic survey, the

IDIQ Contract for Rental of 20 – 24 inch Cutterhead W91278-14-B-0005

00010 - 4 government will make every effort to resolve by attempting to perform an interim survey or by estimating the yardage removed using the existing before dredge survey. When this proves unsuccessful or impossible to reconstruct, the contractor will be paid at the regular 100% PAYTIME rate. Also, reference is made to Section 1000, Paragraph 5.2., entitled: CHARACTER OF MATERIAL which addresses the nature of dredged material expected to be encountered.

(d) Booster Pump use for Incentive Payment – The contractor may elect to use the booster pump to increase production during any period of the contract regardless of Govt. callout of the booster pump found in bid items 7, 8 and 9. For additional details, see section 2.2.10., entitled Booster Pump of SECTION 01000 - Statement of Work - Description/Specifications

(e) Special notice is given regarding upland disposal operations. In no event shall the production incentive clause the contractor to regulate and control activities in the disposal operations such that the physical condition of dikes and weirs are placed in potential danger of failing or of being operated in such a manner that efficient placement of material is not performed. When warranted, the govt.

reserves the right to control all upland disposal operations, including actual discharge locations and pipe placement, in order to assure complete site integrity.

Some dredging assignments will require special placement and handling of discharge material to the extent that dredged production is limited or slowed and in some cases reduced to the point that only the base hourly 100% rate of pay is earned.

2. BID SCHEDULE

(a) Bids based on dredges with smaller than a 20-inch inside diameter will be considered non-responsive. Dredges with a pump diameter discharge less than a 20 inch inside diameter are considered inadequate for satisfactory performance of the work required within the period of the contract. Dredges that have less horsepower than the minimum shown will be considered non-responsive. The dredge must be bid under the diameter discharge from the dredge pump as originally designed by the manufacturer. The discharge lines shall be the same diameter as the dredge pump discharge.

(b) Bidders must insert a price on all numbered items of the bidding schedule. Failure to do so will disqualify the bid.

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

00010 - 5

(d) It is the intent of the Government to secure a dredge meeting the requirements set forth in the Statement of Work of the specifications. The table in the paragraph entitled DREDGE AND ATTENDANT PLANT REQUIREMENTS indicates the estimated average output for dredges of various power based on average theoretical conditions under which this work is to be accomplished. Bids will be evaluated and award will be made on the basis of employment of the plant that will result in the lowest overall total price, as described hereinafter, to the Government for the equipment. This is not to be construed by the Contractor that the Government guarantees this number of hours will be worked.

(e) Bidders should insert the appropriate number of hours for 100% Pay time from the table into the bid schedule.

(f) The Government will check the bidder's computation for accuracy and to insure that the bidder's computation was made in accordance with the above evaluation procedures. In case of variation between the bidder's computation procedures and those prescribed above, the Government will correct the bidder's computation and the bid will be evaluated by the corrected computation.

3. To better facilitate the public bid opening process, all modifications to bids are to be submitted on copies of the latest bid schedules as published in the solicitation or the latest amendment thereto. In lieu of indicating additions/deductions to bid items, all bidders should state their revised prices for each item. The company name should be indicated on the face of the bid schedule to preclude being misplaced.

4. The number of hours indicated on the Bidding Schedule is approximate. The Contractor may be required to work either more or less than the number of hours specified.

5. For Bid Item No. 6. Mobilization/Demobilization for the dredge and attendant plant shall be bid as one lump sum rate for the total effort of mobilizing and demobilizing the entire plant. The mobilization site shall be Sunflower Bar on the Black Warrior-Tombigbee Waterway, BWT Mile 78.0, unless otherwise directed by the contracting officer.

STATEMENT OF WORK – DESCRIPTION/SPECIFICATIONS

1. SCOPE OF WORK:

1.1. DREDGING: The work to be performed under this contract consists of dredging at various locations within the Mobile District. These sites include deep and shallow draft projects and the Gulf Intracoastal Waterway as well as coastal restoration projects, beach nourishment projects and any other project requiring the use of a dredge in Alabama, Mississippi, and Florida. The scope of this contract also provides for any other sizes and/or type of dredge other than those specifically called for in the specifications. The scope also includes supplying dredge related supplies and equipment such as tugs, barges, cranes, geotextile tubes, sheetpile, land based heavy equipment for disposal operations, and other marine equipment associated with channels and coastal restoration projects.

Additional dredges and other marine equipment or materials such as geotextile tubes, sheetpile, additional hand labor crews, etc., that are not specifically called for within these specifications will be negotiated with the individual task order. The Contracting Officer may elect to negotiate cubic yard task orders for some projects in lieu of the standard dredge rental rate.

1.1.1 WORK FOR OTHERS: The work to be performed under this contract also consists of dredging for state ports in Alabama, Mississippi and Florida as well as other non federal entities. Material from these projects ranges from coarse sands to fine silt as well as heavy debris. The contractor can expect greater than normal debris such as steel wire, cable, driftwood and other industrial type products near the docks, piers and other structures located in the dredging template. The contractor will also be expected to dredge closer than normal to private docks, piers and other structures.

All costs associated with work for others shall be included in bid item 4a. DREDGING 100% Pay Time Work for Others.

1.2. DREDGE PLANT: The work to be performed under this contract consists of furnishing a hydraulic cutterhead pipeline dredge with pump discharge of not less than 20-inch diameter or more than 24-inch diameter. The dredge will be complete with all necessary materials, supplies, (including fuel, power, and water) labor, and transportation for maintenance dredging operations as specified in the above paragraph. More specific dredge and attendant plant requirements are discussed below.

1.3. DREDGED MATERIAL DISPOSAL: All removed materials will be placed in approved disposal areas as directed by the Contracting Officer or his Authorized Representative and as discussed in these specifications.

1.4. GENERAL: All work, material and services not expressly called for in these specifications which may be necessary for complete and proper operations to carry out the contract in good faith shall be performed, furnished and installed by the Contractor at no increase in cost to the Government. The Contracting Officer or his Authorized

01 00 00 - 3

Representative may at any time require the Contractor to relocate to a different dredging site should shoaling rates, or other circumstances so dictate. The Government reserves the right to contract additional dredges to perform dredging work on the same projects and geographical area.

2. DREDGE AND ATTENDANT PLANT REQUIREMENTS:

2.1. DREDGE REQUIREMENTS: The dredge offered shall be capable of continuous operation with a minimum horsepower rate as shown below which includes the correlating connected horsepower applied on the main dredge pump. The dredge shall be of sufficient size and with ladder of an appropriate length and construction to work efficiently and safely in a cut with a minimum bottom width of 200 feet and depths of 8 feet minimum. Dredges with pump discharges greater than 24” inside diameter, may bid this schedule; however, no additional credit will be given for the large pump or greater horsepower. For the requested dredge size, most of the work that is anticipated to be performed under this contract is considered a “walking job” for the requested dredge size, therefore, additional pump size and/or horsepower does not justify a competitive advantage in the number of hours in the bid schedule. The Contractor shall have available for use at all times a variety of serviceable interchangeable pump impellers (2 minimum), a spare pump case, and a spare serviceable cutter to permit the dredge to operate efficiently under varying conditions described in paragraph entitled, "PHYSICAL DATA". The dredge shall be capable of dredging upstream as well as downstream and will so operate as directed by the Contracting Officer. The dredge shall be capable of dredging the full bottom dimension of up to 200 feet, plus minimal over-swinging through one swing (cut) of the cutterhead from a given set of the dredge subject to a velocity of less than 2 feet per second given normal conditions. The cut coverage shall be accomplished in one set of the dredge and at or before the dredge reaches its normal set-ahead dredge spud positioning. That cut coverage is expected to be made while at the dredge’s maximum walking speed. The swing of the cutterhead will be accomplished through the use of conventional dredge swing anchors or previously placed deadmen.

The dredge shall be equipped with an electronic positioning system and include the equipment which will record such data.

2.2. HORSEPOWER REQUIREMENTS: Dredge Minimum Horsepower - In using the following table, only one (1) main dredge pump on board the dredge shall be used. The horsepower of auxiliary dredge pumps shall not be considered. Horsepower is equal to the correlating connected brake horsepower applied to the dredge pump. Those dredges which have less horsepower or have less discharge diameter than the minimum shown below for the size dredge bid will be considered non-responsive.

Discharge main pump(s) *2100 H.P. (min) 20-inch Discharge main pump(s) *2400 H.P. (min) 22-inch Discharge main pump(s) *2400 H.P. (min) 24-inch

01 00 00 - 4

FOR THE PURPOSE OF BIDDING AND EVALUATING BIDS, IT WILL BE CONSIDERED THE

DREDGE WILL BE USED FOR THE NUMBER OF HOURS (100% PAY TIME) GIVEN IN THE

FOLLOWING TABLE. HOWEVER, THIS IS NOT TO BE CONSTRUED BY THE CONTRACTOR

THAT THE GOVERNMENT GUARANTEES THAT THE DREDGE WILL BE USED FOR THIS

NUMBER OF HOURS. THE NUMBER OF HOURS SHOWN IN THE TABLE IS ESTIMATED.

THE ACTUAL HOURS MAY BE MORE OR LESS THAN WHAT IS SHOWN.

100% Hours Dredge Size Coastal Work for Others

20 inch Basic Dredge 1500 720 With traveling spuds 1275 612

22 inch Basic Dredge 1240 595 With traveling spuds 1054 506

24 inch Basic Dredge 1042 500 With traveling spuds 886 425

Additional allowance in dredge production will be given for dredges with traveling spuds (spud carriage). A 15% reduction is shown in the table hours for traveling spuds.

The traveling spud must have a minimum of 20’ of travel to be considered for bid purposes. A pre-award inspection of the dredge will be conducted by the Government and the contractor must adequately demonstrate the dredge is capable of traveling 20’ utilizing a traveling spud while the Government representative is present. If it is determined that the traveling spud does not meet this requirement then the contractors bid price will revert to the converted price based on the number of hours in the table above without a traveling spud. In addition, the contractor may elect to bid based on the number of 100% pay hours without a traveling spud and elect to add a traveling spud later in the contract. The 100% bid price for the dredge will then be converted based on the number of hours with a traveling spud provided the traveling spud meets the requirements herein.

The following equation was used to calculate the hours in the table for the bid schedule.

Equation: (1-(0.15 for traveling spud)) X Basic Dredge hours for the dredge size = Number of hours for bid schedule

Example: Dredge A has a 24 inch discharge diameter has a traveling spud.

Applying the equation yields: (1-(0.15)) X 1042 = 886 hours.

2.3. ATTENDANT PLANT:

01 00 00 - 5

2.3.1. Attendant plant shall be composed of such barges, fuel, water, pipe derrick, anchor, etc., floating, submerged, and slip joint discharge pipe, and other attendant or auxiliary plant as may be required for operations under these specifications whether or not these items are specifically mentioned. The auxiliary and attendant plant shall be in good condition and of sufficient size and capability to efficiently serve the dredge.

2.3.2. The Contractor will have available at all times during the duration of work a minimum amount of 15,000 feet combination of floating, submerged, and shore pipeline. The Contractor shall determine for himself the lengths of floating and submerged line necessary. If the Contractor’s combination of floating and submerged line lengths is found to be inefficient, the Contractor may be directed to adjust the combination thereof to a more efficient combination all at no increase in cost to the contract. Also, at the option of the Government, the Contractor may be required to mobilize and utilize additional pipeline. The cost for the initial mobilization, setup, breakdown, demobilization and utilization of the additional pipeline, if needed, will be paid at 1.5 times the bid rate for Bid Item 9 - Intermediate Mobilization and Demobilization of Pipeline per unit of 1,000 feet of pipe. All specifications that apply to Bid Item 9 will apply to the additional pipe. For example:

The contractor bid $10,000 per unit of pipe for Bid Item 9. An additional 5,000 feet of pipe is requested, or five units, above the 15,000 feet required. The contractor would be due $75,000 (1.5 X $10,000 per unit X 5 units = $75,000) for the initial mobilization, setup, breakdown, demobilization and utilization of the pipe.

No contract mod will be executed for the additional pipe. The Contractor will be notified in writing and will be expected to have the additional pipeline on site within 20 days of receiving the written notice. If the additional pipeline is not on site within the 20 days, and no further dredging can be performed as a result of the lack of additional pipeline, then the dredge will be placed on 0% pay time until the entire required pipeline is in place ready for commencement of dredging. The Contractor would then be eligible for 100% pay time once material is satisfactorily passing through the pipeline. Any material that is deposited elsewhere than in places designated or approved by the Contracting Officer may be required to be removed, and the Contractor will be required to redeposit such misplaced material where directed at his expense (no additional costs to this contract). Floating lines and shore pipe will be capable of visual inspection for leaks at all times during the operation. Submerged pipelines shall be air tested before placed in operation.
