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 all items listed on 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 REQUIRED ITEM, HIS BID WILL BE DECLARED NON-RESPONSIVE.

NOTE 3: 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 4: 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).

**NOTE 5: OPTIONAL WORK ITEMS: The Government may require the delivery of, in whole or part, the Optional Item(s) 0004 thru 0010. The Government may exercise the Optional Work Item(s) by written notice to the Contractor. If the Government activates an Optional Work Item(s), the activation will occur while the Contractor’s plant is within the limits of work. No additional mobilization/ demobilization will be paid to the Contractor for the Optional work.

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: Any VEQ analysis under Option Items 0004AA, 0006AA, and 0008AA will be based upon the variation in the line item quantity provided in the Bid Schedule above, and not a variation in any lesser quantity actually awarded under that option line item.

**NOTE 8: The quantity shown in Item 0010 is for evaluation purposes only; payment for this line item will be based on the actual quantity used and they shall be excluded from the “VARIATIONS IN ESTIMATED QUANTITIES” clause.

00010-5 ED 16-003

**NOTE 9: TIME ADJUSTMENT IN THE EVENT OF THE EXERCISE OF OPTIONAL

WORK. In the event that the OPTIONAL WORK items are exercised under the terms of the contract, the time required for completion of the contract shall be 55 calendar days for Items 0004 and 0005; 25 calendar days for Items 0006 and 0007; 15 calendar days of Items 0008 and 0009 in addition to the original contract duration of 235 calendar days established for the BASE WORK items specified in Section 00800, SPECIAL CONTRACT REQUIREMENTS paragraph entitled “COMMENCEMENT, PROSECUTION, AND COMPLETION OF WORK”.

**EVALUATION OF SUBDIVIDED ITEMS

Item Numbers 0002, 0004, 0006, and 0008 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 sub-items.

(End of Clause)

**VARIATIONS IN ESTIMATED QUANTITIES – SUBDIVIDED ITEMS

The Variations in Estimated Quantities Subdivided Items clause is applicable only in Item Numbers 0002, 0004, 0006, and 0008.

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, 0004, 0006, and 0008 are 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, 0004, 0006, and 0008 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 Nos. (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.

PART 1 GENERAL

1.1 SCOPE

The work provided for herein consists of furnishing all plant, labor, materials, and equipment and performing all operations necessary for the removal of all materials to the required dimensions as shown on the contract drawings, satisfactory disposal thereof, and all operations incidental thereto.

1.2 MEASUREMENT

1.2.1 Quantity Surveys

A survey of the sites for dredging shall be made in accordance with the provisions of Section 02 21 10.00 12 SURVEYS AND CHANNEL BOTTOM GRAB SAMPLING and all measurements to determine dredging quantities will be based on the "before dredging" cross sections described therein. The soundings and contours shown on the contract drawings are representative of conditions that existed June 2016, unless otherwise noted on the drawings, and do not necessarily represent existing conditions. The elevations shown thereon shall be verified or corrected by the "before dredging" surveys.

Determinations of quantities to be paid for in the area specified, after having once been made, will not be reopened.

1.2.2 After Dredging Profiles

Should the after dredging cross sections, after dredging profiles and/or soundings described in Section 02 21 10.00 12 SURVEYS AND CHANNEL BOTTOM GRAB SAMPLING disclose any lack of the required dimensions, the Contractor shall redredge the area at no additional expense to the Government. After redredging, the required dimensions shall be verified by rerunning the profiles and after dredging cross sections. Redredging shall be performed until the acceptance profiles and/or soundings show that the required dimensions have been obtained.

1.2.3 Quantity Computations

The quantity of dredged material removed and to be paid for will be measured by the cubic yard by computing the volume along the centerline between the "before-dredging" cross sections and the required dimensions as shown on the contract drawings using the average end area method. No allowance will be made for excessive dredging except as provided in paragraph "Excessive Dredging." In order for the Government to make dredging volume computations, the Contractor shall furnish the track plotter charts described in Section 02 21 10.00 12 SURVEYS AND CHANNEL BOTTOM GRAB SAMPLING, paragraph "Preliminary Field Surveys," and the before dredging data described in Section 02 21 10.00 12 SURVEYS AND CHANNEL BOTTOM GRAB SAMPLING, paragraph "Before and After Dredging Cross Sections."

SECTION 35 20 23.00 12 Page 3 ED 16-003

1.2.4 Acceptance Reach

For the purpose of acceptance, the completed work will be accepted in reaches of 2,000 linear feet along the channel centerline over the full bottom width, as specified and shown on the contract drawings. The Contractor is allowed to take after-dredging cross sections as soon as a station is completed behind the dredge until the entire 2000-foot acceptance reach has been completed. After dredging cross section data for that 2000-foot acceptance reach shall be submitted as one (1) file. The Contractor shall submit the following packet for each 2,000 foot acceptance reach for before dredging and after dredging cross sections.

a. Track Plotter

1.2.5 Timely Performance Of Quantity Surveys

"Before-dredging" quantity surveys shall be made at least 2,000 feet in advance of dredging operations but not more than two (2) weeks prior to commencement of work in the acceptance reach or channel reach to be covered by the survey unless an exception is granted by the Contracting Officer.

Acceptance profiles shall be made within 2,000 feet behind the dredge but not more than two (2) weeks after completion of work in any acceptance reach. Deviations from this limiting time element may be necessary because of unusual job conditions or adverse weather.

1.2.6 Progress Payments

Monthly progress payments will be made based on quantities determined using "before dredging" surveys and the required dimensions, provided the acceptance profiles and any additional soundings that may be directed indicate that the Contractor has met the required dimensions and the acceptance reach length.

1.2.7 Radio And Telephone Communication Equipment

No separate measurement will be made for furnishing and maintaining radio and telephone communication equipment.

1.2.8 Dike Construction

No measurement will be made for dike construction.

1.5 QUALITY CONTROL

The Contractor shall establish and maintain quality control for dredging operations to assure compliance with contract requirements and maintain records of his/her quality control for all dredging operations including but not limited to the following:

(1) Dredging. Visual classification of material; limits of dredging as to bottom grades and widths; side slopes; alignment of channel.

(2) Retaining Dikes and Weirs. The location and amount of area cleared for retaining dikes/weirs and retaining dike/weir borrow, and the location, grade, and side slopes of retaining dikes/weirs.

(3) Dredged Material Disposal. Limits and location of dredged material deposited in a disposal area. Surveillance and location of the dredge discharge outlet, surveillance, and elevation of material placed within each disposal area and location.

(4) Discharge Effluent.

(a) Any shoaling or leak in pipeline, and operation of waste weirs where constructed.

(b) Water Quality.(Confined Upland Disposal Areas)

1. Turbidity Testing. The Contractor shall sample and test return effluent at each spill box at 4-hour intervals beginning four (4) hours after effluent begins to flow over the weir.

Samples shall be representative of effluent returning during normal disposal operations. Return effluent turbidity levels should not exceed 50 NTU. Turbidity testing shall be in accordance with American Public Health Association's Standard Methods, 17th Edition, 1989, Section 213OB, Turbidity Nephelometric Method.

2. Suspended Solid Testing. The Contractor shall sample and

SECTION 35 20 23.00 12 Page 6 ED 16-003 test return effluent at each spill box at four (4) hour intervals beginning four (4) hours after effluent begins to flow over the weir. Samples shall be representative of effluent returning during normal disposal operations.

NOTE: No separate measurement will be made for turbidity testing or suspended solid testing. Payment for turbidity and suspended solid testing will be included in the applicable contract unit prices per cubic yard for "Dredging - Mile 5.0 to Mile 15.0", "Dredging - Mile 15.0 to Mile 17.0 - OW", or "Dredging Devil's Elbow - OW", if Optional Work is exercised.

a. Sampling. Each sample at the weir shall be made up by partially filling, without overflow, a one (1) quart container with the mixture flowing over the weir at not less than three (3) different places in the length of the weir and combining the mixture in a bucket or other suitable container. Base samples of the receiving body of water shall be taken upstream or opposite the direction of the tidal flow where the discharge effluent enters the River or its tributaries as applicable. Each receiving water sample shall be obtained in a bucket or other suitable container submerged to a depth of not over two (2) feet. Upon immediate visual inspection, if settled solids are not present in the weir sample, the density shall be determined by the hydrometer method. When settled solids are present, the density shall be determined by the weight-volume method.

b. Hydrometer Method. When the hydrometer method is used for density determination, a Taylor Soil Hydrometer, graduated to read in grams/liter of suspension, similar or equal to Curtis Matheson Scientific Hydrometers shall be used. The sample shall be thoroughly mixed and transferred to a 1,000 ml laboratory cylinder and the hydrometer used as specified by the manufacturer.

c. Weight-Volume Method. When the weight-volume method is used for density determination, the total sample shall be measured to obtain volume in liters and weight in grams.

Measurements shall be made with a 1,000 ml laboratory cylinder and a scale or balance capable of weighing the sample and cylinder to the nearest gram. The unit weight shall then be obtained by dividing the total weight in grams by the total volume in liters.

3. For each turbidity and suspended solid test the Contractor shall include the time the sample was taken, the results of that test, (NTU reading for turbidity and grams per liter reading for suspended solids), the disposal area and the dredge location in his/her daily report. The Contractor shall also provide the tests samples to the Contracting Officer's Representative.

4. Assistance. Government inspectors plan to inspect and take water samples no less than once a week. The Contractor shall provide any assistance necessary to the Government inspectors.

The Contractor shall construct and maintain a hand railed walkway from a convenient point of access to each spill box and along the entire weir length when in use.
