Written by GovTribe AI · Dec 27, 2023

This solicitation package includes plans and specifications for a federal construction contract opportunity with the U.S. Army Corps of Engineers Omaha District. The scope of work involves placing refurbished stone on revetments and constructing new stone L-head dikes with refusal keys and topsoil at Council Bend and Sandy Point Bend on the Missouri River. The estimated value of construction is between $1 million and $5 million. The solicitation will close on August 26, 2020 at 2:00 pm Central Time. The awarded contractor will be required to furnish all plant, labor, materials and equipment to perform the stone placement and dike construction in accordance with the provided plans and specifications. Relevant project details are included in the drawings of the river bends and construction reference plane as well as flow and elevation data sheets for estimating site conditions during performance.
