This federal contract opportunity solicitation seeks construction services for the Dyke Marsh Wetlands Restoration & Stabilization Project Phase 2 North Sill Extension in Alexandria, Virginia. The solicitation is a 100% small business set-aside issued by the Department of the Army Corps of Engineers Engineering District Baltimore. Services required include continuing construction of an armor stone sill to protect the shoreline by connecting to an existing sill and extending it northward along the coastline. Marine mattresses will be placed from a barge as the foundation for the sill, then large armor stone will be placed on top to build it up with spacing for windows on the sill. The sill also must be tied off in a way that allows the customer to continue extending it later. Civil, geotechnical, and hydrology & hydraulic engineering support will be provided during construction.
