Excavation shall be performed so that the site and the area immediately surrounding the site and affecting operations at the site shall be continually and effectively drained. During backfilling operations and in the formation of dikes, equipment that will overload the structure in passing over and compacting these fills shall not be used.

The Contractor shall replace all weir boards (minimum of four for this contract), make corrections to the existing dikes, clear debris from spill box and piping, provide weir boards, and all other work to prepare the placement area for dredged material placement is the Contractor's responsibility and shall be provided as part of the Contractor's mobilization expenses.

“3.1.2.1 SPILLBOX AND ACCESSWAY CONSTRUCTION

“A new spillbox and drainage piping shall be constructed at the same location and to the same shape and material dimensions of the existing. Drainage pipe shall be provided on a level surface in accordance with ASTM A 760, zinc coated of Type I or II pipe with annular or helical corrugations, asphalt coated, 18-inch. The spillbox shall be anchored to a concrete slab sized and dimensioned to match existing. The slab shall be formed and poured on top of a compacted earth foundation with six inches of gravel between the compacted earth and the slab. The concrete slab shall be anchored into the ground with four screw type anchors placed near each corner of the slab, approximately 1 foot from the edge of each adjacent side, and embedded a minimum of 4 inches into the slab after the slab is poured. A minimum of four L-brackets shall be welded to the spillbox and bolted to the slab anchor bolts when the spillbox is set in place. The slab foundation and new spillbox shall be placed so that the drainage pipe invert elevations matches that of the existing spillbox construction, and the top of the spillbox is at +14.0 feet MLLW (NOS). New weir boards shall be installed up to the +12.0 feet MLLW (NOS) elevation. Weir boards shall be treated in accordance with American Wood Preservers Institute Standard (AWPA) C2 with waterborne preservatives listed in AWPA P5 to a retention level recommended for water contact use. The spillbox shall also be further secured to the ground by six cables, each with cable couplings for adjusting cable tension, and six screw type anchors. These cables shall extend from pad eye brackets welded to the top of the spillbox to the anchors installed in the ground at an approximate angle of 45 degrees. The effluent pipeline coming from the spillbox shall be completely covered by a minimum of 2 feet of materials from the spillbox to the placement of materials for the new dike construction. A walkway shall be constructed from the +14.0 feet elevation on the finished dike to the spill box at the location as indicated. The walkway shall be constructed with pressure treated wood or other materials approved by the Contracting Officer in writing. Walkway shall be treated in accordance with American Wood Preservers Institute Standard (AWPA) C2 with waterborne preservatives listed in AWPA P5 to a retention level recommended for water contact use. The walkway shall be framed and braced to provide safe access to the spill box. The walkway shall have a minimum deck width of 4 feet and have well made continuous hand rails on both sides of the walkway deck. At the terminus of the walkway and the spill box a stepladder shall be constructed on both sides from the deck to the ground. The contractor shall be responsible for the design and construction of the walkway, specifically including the framing, bracing, and sufficient footings. All work shall meet the requirements of the Life Safety Code, EM 385-1-1 and OSHA regulations governing location and use. The Contractor shall replace the spill box, including access walkway, new drainage piping and weir boards, make corrections to the existing dikes, clear debris from the disposal area, and all other work required to prepare the placement area for dredged material placement is the Contractor's responsibility and shall be provided as part of the Contractor's mobilization expenses. All materials repaired or replaced shall be in sizes and type to match existing as approved by the Contracting Officer. All trash and debris shall be removed and disposed in approved landfills at the Contractor's expense. Prior to commencing dredging operations, the weir boards shall be set at a height to assure a minimum ponding depth within the placement area of two feet measured at the spill box.

Additionally, for the duration of the contract the Contractor shall be responsible to maintain the placement area dikes and operate the spillbox by keeping spillway weirs at the correct level and free of trash and debris at all times to maintain:

(1) the minimum required ponding level;

(2) specified freeboard; and
