Improvements to Raise the Perimeter Berm for the RM Clayton Water Reclamation Center

The Mobile District Corps of Engineers has a need for a construction contract to “design and construct” improvements to raise the perimeter berm for the RM Clayton Water Reclamation Center located in Atlanta, Georgia. The existing perimeter berm requires tree removal, placing additional earthen fill, and a sheet pile wall designed to protect the water reclamation plant from surface overtopping floodwaters of the nearby Chattahoochee River and its tributaries. The crest of the perimeter berm shall be set approximately 3 feet above the typical elevation for the existing perimeter berm. The berm consists of three segments, two along the Chattahoochee River (approx. 1500 feet total) separated by an overpass abutment for the Atlanta Highway bridge over the river and one segment along low ground on the opposite side of the facility (approx. 1400 feet). The City of Atlanta has provided a conceptual design which will be made available “for information only”. This include geotechnical boring data and report, a hydraulic and hydrologic study, project footprint, utility overlays (to extent available), and other information can be provided upon request. The contractor shall be responsible for locating/verifying all utilities and making any necessary design considerations prior to design completion and construction. It is desired to leave utilities in place to the extent possible, with only minor realignments anticipated, if any. The water reclamation facility is the primary wastewater treatment facility for the City of Atlanta and must remain in operation during this construction. The facility may have other upgrades ongoing by contract within the facility. Space must be identified during design for material laydown, parking and office trailer that will not impede the daily facility operations or expansions and as close as feasible to the construction area.
