The scope of the requirement includes construction of a repair or replacement weir for the existing water intake weir in the Big Piney River with a service life of 10 years. Weir repair has been designed to maintain the current water pool requirements for the water intake and includes, up and down stream cofferdams, containment walls, and weir injection, as needed. Construction of the weir repair must be within the current environmental permitting, Nationwide Permit 3, for the existing weir. An aquatic organism passage will be included as part of the weir design per environmental requirements, Section 7 Consultation, Fish and Wildlife Coordination Act. The existing canoe portage path is to be replaced as needed to install the new weir and aquatic organism bypass. Dewatering permissible with approval from 1 April to 1 November. Background: The original weir for the water intake was constructed in the early 1940s, the design drawing is dated September 1942. Historical images from the bridge construction downstream of the weir in 1957 show the weir in the background. From these images it looks like the original weir was replaced with a rock covered earthen berm. It is possible that soil and rock simply accumulated onto the original concrete weir, but we assumed a worse case of the original weir being removed or washed out. In 1986 the weir was raised and repaired. The raise consisted of placing additional soil and rock fill on the existing earthen berm then placing gabion baskets and a concrete cap. The bank slopes also had gabion basket protection placed on them when the weir was raised. Fish passage was one of the concerns listed in the 1986 404 permit, but fish passage was not incorporated into the weir repair. The water intake weir has deteriorated since the 1986 repair. The concrete cap has several large cracks in the surface, the gabion baskets below the cap can be seen in locations, and some pieces of the downstream edge of the concrete weir cap have broken off. The gabion baskets have also deteriorated, many are missing rock material or have broken open. During boring it was observed that there are large voids under the concrete cap and water was flowing through the weir. Site visit details are included in the solicitation. This is a Request for Proposal (RFP). The estimated performance period for completion of construction is 365 calendar days from the issuance of the Notice to Proceed (NTP). The NAICS code is 237990 Other Heavy and Civil Engineering Construction, with a small business size standard of $39.5 Million in average annual receipts.
