1.5 LOCATION AND CHARACTER OF BORROW MATERIAL

1.5.1 Character of Borrow Material

The character of the material in the offshore borrow area is believed to be as indicated by the results of Government-conducted sampling and analysis. Vibracore logs, and sieve curves are presented in Appendix B41 and B42, respectively. The locations of vibrational cores, from which samples were extracted are shown on the drawings. These locations are in or near the limits established by the drawings for the specified borrow area.

The information depicted on the vibrational core logs represents the results of subsurface explorations made on the dates indicated and can only be considered as conditions existing at that time and at the specific location where retrieved. Due to complex geologic conditions within the coastal environment, boulders, cobbles, gravel, silt and clay seams may be encountered as well as sand. The beachfill must be composed predominately of sand as defined by ASTM D2487-06. Boulders, cobbles and coarse gravel defined by the same designation are prohibited from being part of the beachfill. Fine gravel will be limited to less than 10 percent of the beachfill. Manmade materials are also prohibited from being part of the beachfill. No additional compensation will be provided, for routine moves of the dredge(s) within the limits of the borrow area(s) shown; moves required to ensure compliance with these specification for beachfill content and/or to optimize production are routine.

Munitions and explosives of concern (MEC) may also be encountered in the borrow area. See Section 01 35 30 MUNITIONS AND EXPLOSIVES OF CONCERN (MEC) CONSTRUCTION SUPPORT for all requirements related to potentially encountering MEC in the borrow area.

1.5.2 Location of Borrow Area

The location of the borrow area and the limits to which removal of material is permitted is shown on the drawings.

1.5.2.1 Maximum Allowable Depth for Removal

The maximum allowable depth for removal of material from the borrow area

Section 35 31 00 Page 4 is as indicated on the borrow area drawing. To cover the inaccuracies of the dredging process, the Contractor may remove material in the borrow area to a depth of not more than 1 foot below the maximum allowable depth, as shown. Unless specifically directed by the Contracting Officer, no payment will be made for material removed from below this depth or from outside the borrow area limits.

1.5.3 Nature of Borrow Area

The surveys of the borrow area shown on the drawings are the most recent survey available. The borrow area conditions are dynamic in nature.

Therefore the contours shown on the drawings may not be an accurate representation of the depths and conditions existing at the commencement of dredging operations under this contract.

3.7 PLACEMENT OF BEACHFILL

3.7.1 General

Beachfill material shall be placed and shaped to the beachfill template lines, grades, slopes, and elevations shown on the drawings. There shall be no pronounced ridges or wash holes in the final grades and slopes unless otherwise indicated. Beachfill lines and grades shall extend linearly between payment sections with no scallops in planform contours.

Conduct work operations so that no areas landward of the work limits shown on the drawings are disturbed. Land-based equipment shall be used for grading the beachfill material.

If the Contractor stockpiles material and subsequently uses land-based equipment to move the material to its final position, the Contractor shall wait 24 hours before after-surveys are conducted of that area.

Section 35 31 00 Page 7

3.7.2 Template Quantity

The required template placement quantity of sand between survey lines will be determined by the average-end-area method using the difference in cross-sectional area between (1) the profile surveys obtained by the Contractor before the beachfill operations in accordance with Section 01 71 23 SURVEY REQUIREMENTS and (2) the template lines shown on the drawings.

3.7.3 Bid Quantity

The bid quantity of beachfill material shall be placed to the beachfill template lines, grades, slopes and elevations as specified above, and additional quantity in excess of the template quantity shall be placed by advancing the seaward edge of berm uniformly throughout the length of the project. (Ex. If the Bid Quantity = 400,000 CY and Template Quantity = 350,000; then 50,000 CY shall be used to advance the seaward edge of berm). In the event that a shortage of material exists between the bid quantity and the template quantity, the seaward edge of berm shall be reduced landward uniformly throughout the length of the project.

3.7.4 Placement Tolerances

a. For placement only, a vertical tolerance of plus 0.5 feet and minus 0.0 will be permitted on the berm portion of the beach; a vertical tolerance of plus 0.2 feet and minus 0.0 will be permitted on the dune portion of the beach.

b. Adjusted Construction Template: Beachfill shall be placed to the minimum seaward edge of berm and to the foreshore slope indicated on the drawings, however, the Contractor may adjust the construction template by advancing the edge of berm seaward (at the same elevation) and modifying the foreshore slope to achieve the required placement quantity within the footprint of the beachfill template shown on the drawings. An example of an adjusted construction template is attached to this section.

c. In the event that the berm elevation, the minimum seaward edge of berm or the required placement quantities are not met, recommence beachfill operations until the requirements are met. The Contractor will not be required to recommence beachfill operations in the event of erosion and/or storm damage in areas where beachfill has been completed and the survey data demonstrates compliance with the contract requirements.

3.7.5 Payment Tolerances

For payment, there will be no vertical tolerance permitted on the berm or dune portions of the beach. Payment will be made for placement, only to the lines and grades shown on the drawings (see Measurement and Payment paragraph below). In the event the Contractor adjusts the construction template as specified herein, payment will be made for measured quantity, not exceeding the required placement quantity. Payment will not be made for material placed above the required berm elevation, or placed seaward of the toe of slope. The toe of slope shall be defined as the point of intersection of the template as shown on the drawings with the before-placement survey profile.

3.7.6 Removal of Debris
