About this file
This solicitation package includes plans and specifications for a small business set-aside contract to complete Phase 2 of the Chesapeake Bay Oyster Recovery Program's Piankatank River Reef Habitat restoration project. The project scope involves obtaining, transporting, and placing approximately 7.98 acres of Class A-1 riprap reef substrate by mechanical clamshell from a barge according to the design drawings. There are also options to place additional reef structures on 4.25, 2.96, and 3.36 acre areas. Reef placement will create 30-foot wide rows spaced 45 feet apart to a thickness between 12-18 inches above the existing river bottom in water depths from 0.96 to 0.10 feet MLLW. The Norfolk District of the Army Corps of Engineers will issue the firm fixed-price IFB and manage the contract in partnership with the Virginia Marine Resources Commission to restore oyster habitat across 53 total acres of Public Baylor Grounds in the Piankatank River near Mathews and Middlesex Counties, Virginia.
