The Department of the Interior National Park Service Midwest Region is seeking contractors for a comprehensive septic system replacement project at the Buffalo National Recreation Area's Kyles Landing Comfort Station in Arkansas. The scope of work involves removing and replacing the existing sanitary sewer system, which was installed in 1997 and has reached the end of its useful life, including removal of existing septic tanks and installation of new septic tanks, a dual pump lift station with automatic controls and flow measurement, a new force main, and a new mound/drain field. This is an Invitation for Bid (IFB) procurement requiring contractors to have appropriate state licensing for septic system installation and comply with prevailing wage requirements for heavy construction work in Arkansas. The contract will be awarded as a firm-fixed price arrangement, with bids evaluated based on the lowest responsive and responsible bidder meeting all technical specifications.
