Data from previous surveys will be provided to the Contractor in advance of the pre-placement surveys. The Contractor shall overlay the previous surveys with pre-placement surveys as a quality control measure.

3.4.8 Photographic Documentation of Surveys

During the completion of pre-placement condition surveys, digital color photographs shall be taken at each profile line to provide visual documentation of the beach. The digital photographs shall be taken from a point on the baseline located approximately halfway between the water line and the Contractor work limit. The photographs shall be taken in three directions. The first shall be taken facing perpendicular to the baseline azimuth. The direction of the photographs shall be defined by facing the ocean while standing on the baseline and turning counterclockwise approximately 90 degrees (generally facing a northerly or easterly direction along the coast of Delaware). The second shall be taken parallel to the baseline azimuth and facing seaward. The third shall be taken parallel to the baseline azimuth and facing landward. Any obstructions along the baseline azimuth which preclude collection of data shall be documented with additional digital photographs. Digital files and a set of hardcopy images shall be provided to the Government in a brief report documenting the surveys, weather conditions, beach conditions and field notes.

3.5 BEFORE- AND AFTER-BEACHFILL SURVEYS

3.5.1 Completion Time Requirements

Before-beachfill surveys of a location shall be conducted no more than 10 calendar days before after-beachfill surveys of that location.

3.5.2 Daily Data Submission

Raw and edited data from the before- and after-beachfill surveys, in HYPACK formats i.e. .RAW, .EDT, .HSX, shall be submitted to the COR on a daily basis.

3.5.3 Locations of Survey Lines

The survey cross-sections shall be taken every 100 feetand also at the locations of the pre-placement surveys in the locations requiring beachfill. Surveys are only required in Rehoboth Beach, Bethany Beach and South Bethany if options for those areas are awarded.

3.5.4 Description of Required Survey Lines

The survey cross sections shall extend 1,000 feet seaward from the survey baseline. The origin of the new profile lines shall be the survey baseline, as shown on sections on the contract drawings.

3.5.5 Intervals Required

Elevations along the cross-sections shall be taken at a maximum of 10 foot intervals, with additional elevations taken at breaks in grade and as

SECTION 01 71 23 Page 6

3.2 PRE-PLACEMENT CONDITION SURVEYS

The beachfill area conditions are dynamic in nature. Conditions existing during the preparation of this contract may not be an accurate representation of the beachfill area conditions existing at the commencement of beachfill operations. Consequently, the Contractor shall obtain pre-placement condition survey cross sections, in accordance with Section 01 71 23 SURVEY REQUIREMENTS. Upon receipt of the pre-placement surveys as specified in Section 01 71 23 SURVEY REQUIREMENTS, the Government will re-issue revised beachfill sections. Commencement of beachfill will not be permitted until these surveys have been submitted and approved, and revised beachfill section re-issued by the Government.

3.3 MAINTENANCE OF DRAINANGE OUTFALLS

The Contractor shall maintain drainage of all outfalls at all times throughout the duration of the contract.

3.4 REMOVAL OF STRUCTURES

All existing structures, including but not limited to, the volleyball poles and bases, will be removed by others.

3.5 PLACEMENT OF BEACHFILL

3.5.1 General

Beachfill material shall be placed and shaped to the beachfill template lines, grades, slopes, and elevations shown on the contract 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.

The required placement quantity of sand in each acceptance section will be determined by the difference in cross-sectional area between (1) the cross-section 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.

For placement, a vertical tolerance of plus 0.2 feet and minus 0 will be permitted on the berm portion of the beach. 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 seaward edge of berm (at the same elevation) and adjusting 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.

In the event that the berm elevation, the minimum seaward edge of berm or the required placement quantities are not met in each acceptance section, the Contractor shall recommence beachfill operations until the requirements are met.

Payment will be made for placement only to the lines and grades shown on the contract 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

SECTION 35 31 00 Page 5 slope shall be defined as the point of intersection of the template as shown on the drawings with the before-placement survey cross section.

The Contractor shall conduct his work operations so that no areas landward of the work limits shown on the Contract Drawings are disturbed.

Land-based equipment shall be used for grading the beachfill material.

3.5.2 Removal of Debris

When MEC or MEC-like items are detected on the beach, the Contractor shall implement the procedures specified in Section 01 35 30 MUNITIONS AND EXPLOSIVES OF CONCERN (MEC) CONSTRUCTION SUPPORT. When any non-MEC item that physically should not be able to pass through the intake screening opening is detected in the discharge screening device, the Contractor shall implement the following procedures:

a. The Contractor shall stop dredging and beachfill work.

b. The Contractor shall report the incident to the COR.

c. Intake and/or discharge screening devices shall be repaired if necessary.

d. Beachfill and/or dredging work will not be permitted to re-commence until notification from the Contracting Officer.

During the operation of placing beachfill material, all debris resulting from construction operations shall be removed from the work site and disposed of at no additional cost to the Government. Such disposal shall comply with all applicable Federal, state and local laws. Such materials shall be removed from the site of the work before the date of completion of the work under these specifications. Debris may be temporarily stored on-site in a dumpster or roll-off box. Do not bury any debris collected in the screening device in the beachfill.

3.5.3 Placement of Beachfill Beneath Existing Beach Structures

Placement and grading of beachfill material by hand may be required beneath existing beach structures. The Contractor shall protect the existing beach structures from damage. Placement of beachfill material beneath structures shall be done in a manner that minimizes the ponding of water. If ponded areas are created due to the Contractor's operations the Contractor shall pump these areas dry at no additional cost to the Government. Any structures damaged shall be repaired at no additional cost to the Government.

3.5.4 Hydraulic and Hopper Dredges

All pipelines used with hydraulic dredges shall be kept in good condition at all times, and any leaks or breaks shall be promptly repaired. Material excavated by hopper dredge shall be loaded into bins or hoppers and pumped directly to the beachfill area by a means which shall prevent the loss of any material into the ocean. Special care shall be taken to ensure that hoppers do not leak during any phase of the contract work.

3.5.5 Submerged Dredge Pipe

Barricades, warning signs, and lights shall be provided by the Contractor, SECTION 35 31 00 Page 6
