SECTION 35 20 23 Page 16

3.3.4 Required Depth, Allowable Overdepth, and Side Slopes

3.3.4.1 Required Depth

The material actually removed from the designated areas to be dredged, to a depth of not more than the required depth shown on the drawings, will be estimated and paid for in accordance with the provisions contained in the subparagraphs "Measurement" and "Payment" of Section 01 22 00 MEASUREMENT

AND PAYMENT.

3.3.4.2 Allowable Overdepth

To cover the inaccuracies of the dredging process, material actually removed from the designated areas to be dredged, to a depth below the required depth of not more than the allowable overdepth shown on the drawings, will be measured and paid for in accordance with the provisions contained in the subparagraphs "Measurement" and "Payment" of Section

01 22 00 MEASUREMENT AND PAYMENT.

3.3.4.3 Side Slopes

Side slope dredging will be required. Side slopes may be formed by box cutting, step cutting, or dredging along the side slope. Material actually removed, within the limits approved by the Contracting Officer, to provide for final side slopes not flatter than that shown on the contract drawings, but not in excess of the amount originally lying above this limiting side slope, will be measured and paid for in accordance with the provisions contained in subparagraphs "Measurement" and "Payment" of Section 01 22 00 MEASUREMENT AND PAYMENT. Such amount will be estimated and paid for whether dredged in original position or by box cut dredging whereby a space is dredged below the allowable side slope plane on the bottom of the slope for upslope material capable of falling into the cut. End slopes and transition slopes will not be estimated or paid for under this contract.

In such cases, a 0 horizontal on 1 vertical will be used with no upslope allowance provision applied outside the required prism.

3.3.5 Excessive Dredging

It is recognized that the limits of dredging need to extend beyond the pay prism in order to remove material from within the pay prism. Therefore, the limits of active dredging may exceed the limits of the pay prism in vertical dimension as well as horizontal dimension to the extent necessary to remove material from the pay prism. Indirect impacts (sideslope sloughing, etc) may extend even beyond the limits of active dredging.

Nevertheless, material taken from beyond the limits of the pay prism as described in subparagraphs "Allowable Overdepth" and "Side Slopes" above will be deducted from the total amount dredged as excessive overdepth dredging, or excessive sideslope 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 the paragraphs FINAL EXAMINATION AND ACCEPTANCE or SHOALING of this Section.

3.3.6 Areas to be Dredged

Based on information currently available to the Government, areas known to require dredging are depicted on the drawings as hatched areas. The actual areas to be dredged may vary from the hatched areas shown in the drawings.

In order to provide the required project dimensions within and throughout the project limits shown on the drawings, the Contractor shall remove

SECTION 35 20 23 Page 17 material located within the project limits as directed by the Contracting Officer, regardless of whether the material is located in a hatched area or not. Payment for all dredged material dredged from a hatched area will be made at the applicable contract unit price. Payment for all material dredged from a non-hatched area may be made at the applicable contract unit price; however, the Contractor may request an adjustment to the contract unit price in accordance with DFAR Clause 252.243-7002 REQUESTS FOR EQUITABLE ADJUSTMENT and/or FAR Clause 52.243-4 CHANGES of Section 00700 CONTRACT CLAUSES in Volume 1.

3.3.7 Acceptance Sections

For purposes of payment, the work to be done will be divided into acceptance sections. Prior to any dredging, the Contractor shall prepare and provide a proposed acceptance sections plan for approval by the Contracting Officer. Generally, the work should be divided into areas that equate to approximately 30 days of dredging or that constitute separable or definable features of work.

3.4 TRANSPORTATION OF EXCAVATED MATERIAL

3.4.1 General

Material excavated shall be transported to and deposited in the nearshore placement area. The average distance to which the material will have to be transported is approximately 2.5 miles with a maximum distance of 3.6 miles.

3.4.2 Scow Spillage and Leakage

Any excavated sand which is lost in transit or permitted to flow into the offshore waters outside the nearshore placement area or onto the upland from the point the sand is discharged on the beach will not be subject to payment. The development of a leak shall be promptly repaired and the dredge and pumpout operations shall be shut down until repairs are completed to the satisfaction of the Contracting Officer. Failure to repair leaks or change the method of operations, which result in overflow, leakage or spillage that exceeds turbidity and water quality standards during loading and transport to the discharge site, will result in suspension of dredging and pumpout operations and prompt repair or change in operation.

3.4.3 Pipeline Transportation

The Contractor shall maintain a tight discharge pipeline at all times. The joints shall be so constructed as to preclude spillage and leakage. The method of transporting the fill from the excavation area to the nearshore placement area shall be approved by the Contracting Officer.

3.4.3.1 Pipeline Restrictions

The Contractor shall not lay upland pipeline along the beach south of the right of way line shown on the drawings because of high public use.

Furthermore, there will be an open water swimming event occurring between June 3rd to June 5th which will require the contractor to move their offshore pipeline 2,000 feet from the shore. This will be discussed at the preconstruction conference with the Contracting officer and local sponsor.

SECTION 35 20 23 Page 18

3.4.3.2 Dredge Discharge Pipeline

The Contractor shall plainly mark the pipeline access routes with conspicuous stakes, targets and/or buoys to be maintained throughout the contract operations. A tight dredge discharge pipeline shall be maintained to prevent spilling of dredged material or dredge water outside of the nearshore placement area. The Contractor shall provide and maintain radio communication between the dredge and the nearshore placement area and the dredge and the Contracting Officer. The pipeline shall be inspected at least twice daily for leaks. Failure to immediately repair leaks in the discharge pipeline will result in suspension of dredging operations and require prompt repair of pipeline as a prerequisite to the resumption of dredging.
