Description

This is a Sources Sought notice is issued for market research purposes by the U.S. Army Corps of Engineers, Huntington District to address the potential use of Project Labor Agreements for a large scale construction project exceeding $35 million in Milton, WV for the Lower Mud River Flood Damage Reduction Project. This notice does not constitute a solicitation announcement nor does it restrict the Government to a specific acquisition approach. Summary of Scope of Work: The Milton, WV Flood Risk Management Project aims to provide flood risk reduction and management to the residences and businesses of Milton, West Virginia. The area has a history of flooding dating back to the early 1900s with several large flood events on record, creating public safety issues and economic damage. The project is designed to significantly reduce flood risk to most of the City of Milton by constructing a levee and rerouting part of the river to provide benefits to over 600 structures including residences and businesses, along with protection of public structures, personal property, and critical infrastructure. The project will require heavy construction for earthwork, underground seepage barrier, cast-in-place concrete, buildings, utilities, slope protection, and environmental mitigation. Plan Features – designed for 4% annual chance of exceedance (250-year return frequency) Earthen Levee Construction: This project includes the construction of approximately 6,800 linear feet of earthen levee. A key feature is a full-depth soil bentonite seepage barrier (variable depth to bedrock approximately 20' to 40') and a managed overtopping section, requiring expertise in large-scale earthmoving and geotechnical engineering. Concrete Floodwall and Structures: Approximately 1,500 linear feet of concrete floodwall will be built, with a full-depth sheetpile for reinforcement (variable depth to bedrock approximately 20' to 40') with the exception of two sections where a toe drain will be added. The project also includes a stop log closure structure at Bill Blenko Drive, demanding skilled concrete and structural work. Pumping and Water Management Systems: Two pump stations will be installed with a capacity of 87,000 GPM (Johns Branch) and 19,000 GPM (Newmans Branch). Each pump station will have a gravity culvert, gatewell, and discharge lines up and over the levee. This, along with five gravity outfalls, involves significant mechanical, electrical, and plumbing trades for the installation and excavation of associated ponding areas. River Channel Relocation and Modification: A significant portion of the project involves the relocation of approximately 1,200 linear feet of the Mud River, which will be shortened to a new 800-foot channel. This work also includes channel geometry benching, requiring expertise in river engineering and heavy excavation. Utility and Infrastructure Relocation: The project necessitates the relocation of the city's raw water intake and a low-flow weir. This,…
