The project site is located at Disposal Area 13B in Savannah Harbor, Jasper County, South Carolina. Horizontal control shall be NAD83 Georgia East state plane coordinate system. Vertical control shall be Mean Low Low Wat er based on the NGVD29 datum. Construction work described herein applies to the placing of silt fence, site clearing and grubbing, dewatering, harvesting of earth materials for placement, survey before and after construction, placement and compaction of ea rth materials, base plate anchors, vinyl sheet piles and catwalk installation at weir locations, installation of air hoses at underdrain lines, establishment of turf, cleanup, and maintenance of roadways. The perimeter of the disposal area is 21,832 (feet) . There are eight access ramps that total 2,543 feet in length. The bird island areas are eight (8) acres each (16 acres total). There are five (5) weirs requiring base plate anchors, vinyl sheet piles, and catwalk installation. Three air hoses are to be i nstalled, one at each end of the three existing 12 inch diameter underdrain collector pipes. Prior to the embankment work, construction, the Construction Contractor shall perform and complete (1) silt fence installation; (2) all required clearing, and/or s tripping operations; (3) the setting of all alignments for dike raising construction, ramp access and bird island limits; (4) and the setting of cross section stations. The dike shall be staked out at 100-foot increments on even stations and at all PCs, P Is, and PTs of curves on the dike by the Construction Contractor. Access ramps shall be staked out at 20-foot increments along proposed centerlines. The Contractor shall locate and flag existing survey markers, bird island settlement riser tubes, and und erdrain locations that are not to be disturbed. The Contractor shall obtain by survey the elevations of the eight existing bird island settlement plates and associated top of riser tubes. Earth materials for construction shall be obtained from Dredged Mate rial Containment Area 13B or 13A. The placing of earth materials while raising dikes, ramps, and bird islands are limited to one vertical foot per week. Catwalks for installation at weir locations will be furnished by the Government. All connecting hardwar e, base plate anchors, vinyl sheet piles, and other material and labor needed for installation shall be furnished by the Contractor. Tolerance limits are identified for dike and ramp construction that are considered adequate for construction. There may be options.

The Contractor shall be aware that payment will be based on material placed within the construction templates defined. There will be no payments made for mate rials placed outside the design. Interiors of the containment areas are constantly undergoing a drying and consolidation process that renders the contract survey inaccurate. The Contractor shall perform a topographic survey of borrow areas identified befor e harvesting of materials. The difference between the contract survey and the before borrow survey is the result of drying and consolidation of the site, and as such, does not constitute a changed or differing site condition as defined elsewhere in thi s contract.
