(End of Summary of Changes)

Encls As stated

Maintenance Dredging, AIWW, Select Sites W912HN-09-B-0021 Georgia and South Carolina designated easements of undiked disposal areas.

3.1.5 Head Sections

Head sections will be placed so as to minimize impacts to Spartina marsh and waterways from dredging and disposal operations.

3.2 SURVEILLANCE

For the duration of this Contract, the Contractor will maintain 24-hour surveillance and control over the disposal areas, diked areas, and weirs.

The Contractor shall provide two men per shift to perform this surveillance and ensure that communication with the dredge is maintained at all times.

3.3 DIKED DISPOSAL SITES (14B)

3.3.1 Weirs

The weirs will be used to decant the water from the disposal areas. The Contractor will be responsible for repairing failures of dikes, weirs, and discharge structures which occur during his disposal operations. Payment for such repairs or reconstruction shall not be made nor shall the Government make payment for the dredge plant when it is not operating as a result of dike, weir, or discharge structure failure. The Contractor shall provide a vehicle, other than construction equipment, capable of transporting the dike surveillance crews to perform their mission.

3.3.2 Pipe Ramps

The Contractor shall fill or shape the ramps as necessary to suit his needs. No material from the existing dikes shall be used for pipe ramp construction. Material used in the pipe ramp construction shall come from the interior of the disposal areas. No separate payment will be made for maintenance of the dikes and pipe ramps; the pipe ramps are considered incidental and should be reflected in the price for Bid Item No. 7001 Mobilization and Demobilization. The Contractor shall make necessary repairs to the weirs and outfall pipes in order to contain the dredged material and maintain water quality of the effluent. The Contractor shall patrol, maintain and repair any damage to existing weirs and outfall pipes under the dikes.

3.3.3 Reasonable Care

The Contractor shall be responsible for reasonable care in the use of the disposal area, and for the operations and control of the weirs. Stoplogs for the weirs shall be provided by the Contractor as necessary for his operations. However, adequate stoplogs shall be provided and all flows managed so that all release of effluent can be stopped if required by the Contracting Officer or his Authorized Representative. The Contractor may be required by the Contracting Officer's Representative to maintain a particular water level within Area 14B to provide adequate water quality or to benefit migratory birds, including shorebirds and waterfowl.

3.3.4 Stoplogs

All stoplogs shall be 3 inch by 6 inch, cut to fit. All stoplogs shall be of dense select structural southern pine lumber and pressure treated with either Ammoniacal Copper Arsenate (ACA) or Chromated Copper Arsenate (CCA) and shall conform to AWPA C18 (soil contact). A certificate from any

3.5 OVERDEPTH AND SIDE SLOPES

(April 2008 SAS)

3.5.1 Overdepth

To cover the inaccuracies of the dredging process, material actually removed from within the specified areas to be dredged to a depth of not more than 2 feet measured vertically below the required depth will be computed and paid for at the contract unit price for Bid Items Nos. 7003 through 7010, Maintenance Dredging. The Contractor shall not remove any overdepth material where material above the required depth is not available.

3.5.2 Side Slopes

Material removed to provide the specified side slopes shall be computed and paid for at the contract unit price for Bid Items Nos. 7003 through 7010, Maintenance Dredging. In computing the limiting amount of side slope dredging, an overdepth of 2 feet measured vertically shall be used. Side slope dredging is required. All areas of the Atlantic Intracoastal Waterway have a side slope of 1 vertical to 3 horizontal.

3.5.3 Excessive Dredging

Material taken from beyond the limits as described in paragraphs OVERDEPTH AND SIDE SLOPES above shall be deducted from the total amount dredged as excessive dredging for which payment will not be made. Nothing herein shall be construed to prevent payment for the removal of shoals performed in accordance with the applicable provisions of either paragraphs FINAL EXAMINATION AND ACCEPTANCE or SHOALING of this section.

3.6 SURVEYS

(JAN 1994 SAS)

3.6.1 Acceptance and Final Payment

Acceptance and final payment for each acceptance section shall be based (as described in paragraph MEASUREMENT AND PAYMENT of this section) on Before and After Surveys made by the Government. The Government shall make Before and After Surveys only after the Contractor provides the following notices in writing:

3.6.1.1 Commencement Notice

Fifteen days before dredging is to begin in an acceptance section, the Contractor shall provide to the Contracting Officer or his Authorized Representative written notice of the commencement of dredging. Within 15 days (weather permitting) after receipt of the notice, a Before Survey will be performed for the entire acceptance section by the Government. If the commencement of dredging in the acceptance section is delayed more than 15 days after the date of the Before Survey, the Government will, at the Contractor's request, resurvey the entire acceptance section. Unless the delay is caused by the event(s) described in clause FAR 52.211-12 of SECTION 00800 and clause FAR 52.249-10 of SECTION 00700, the additional survey will be charged to the Contractor at the rate of $2,700 per survey-crew day required by the Government to mobilize, survey, and demobilize.

SECTION 35 20 23 Page 10

(8) Survey data in ASCII format on CD'S. This data should be in the form of x-coordinate, y-coordinate, reduced depth sounding, in column format and separated by spaces. Each survey line should be separated by a header showing station number and number of points on that survey line.

3.7 ESTIMATED QUANTITIES

(JUN 2000 SAS)

The following estimated quantities are available for Bid Items Nos. 0002 through 0005, Maintenance Dredging.

SECTION 35 20 23 Page 12

3.11 MEASUREMENT AND PAYMENT

(JUN 2000 SAS)

3.11.1 Measurement

The total amount of material removed and to be paid for under the contract will be measured by the cubic yard in situ by computing the volume between the bottom surface shown by soundings of the Before Dredging Survey and the bottom surface shown by the soundings of the After Dredging Survey made as soon as practicable after the work has been completed, less any deductions that may be required for excessive dredging, as described in paragraph OVERDEPTH AND SIDE SLOPES, and misplaced material, as described in paragraph DISPOSAL AREA OPERATIONS.

The maps and/or drawings already prepared (clause CONTRACT DRAWINGS AND SPECIFICATIONS (DFARS 52.236-7001) of SECTION 00700) are believed to represent accurately conditions existing at the time surveyed, but the depths shown thereon will be verified and corrected by soundings taken within 14 days before dredging. Determination of quantities removed and the deductions made therefrom to determine quantities by place measurement to be paid for in the area specified, after having once been made, will not be reopened, except on evidence of collusion, fraud, or obvious error.

Soundings for all dredging surveys under this contract will be obtained by the use of a dual frequency marine depth recorder. Sensitivity setting will be adjusted to reflect the type bottom material in the area being surveyed.

In areas where double bottom (fluff) conditions are encountered, the 28 Khz transducer will be used for quality assurance and yardage calculations.

3.11.2 Payment

Payment for all mobilization and demobilization (Bid Item No. 7001) will be lump sum and will be made in accordance with SECTION 00800, clause DFARS

52.236-7004, PAYMENT FOR MOBILIZATION AND DEMOBILIZATION.

Final payment for dredging will be at the bid unit price and based on quantities computed as described above. For reaches where more than one disposal area is designated, the Contractor will bear any additional pumping cost if the Contracting Officer or his authorized representative determines material must be placed in the more distant disposal area.

Monthly partial payments for completed dredging of acceptance sections for Bid Items 7003 through 7010, Maintenance Dredging will be based on quantities determined by soundings and/or sweepings taken behind the dredge or dredge plant and from data furnished on the Contractor's Daily Report of Operations.

3.12 CONTINUITY OF WORK

(JUN 1999 SAS)

No payment will be made for work done in any area designated by the Contracting Officer or his Authorized Representative until the full depth required under the Contract is secured in the whole of such area, nor will payment be made for excavation in any area not adjacent to and in prolongation of areas where full depth has been secured except by decision of the Contracting Officer or his Authorized Representative. Should any such nonadjacent area be excavated to full depth during the operations carried on under the Contract, payment for all work therein may be deferred until the required depth has been made in the area intervening.
