Z--Excavate and install specifics of a Flood Protection Plan, for the Saw Mill Run area of Pittsburgh, PA.

Solicitation W911WN09B0034 is a 100 percent small business set-aside contract issued by the Department of Defense through the U.S. Army Engineer District Pittsburgh for the Saw Mill Run Flood Protection Project in Pittsburgh, Pennsylvania. The scope of work involves extensive waterway and marine construction, including excavation in the Ohio River and within the CSX Railroad and West Carson Street culverts. Key deliverables include the installation of sheet pile walls and stone protection at the river bank, placement of concrete floor slabs and walls to protect the South Main Street Bridge abutments, and the installation of revetment mat slope protection on the right bank at the former Plank Street bridge and the left bank between Plank Street and Alexander Street. The project is governed by detailed technical specifications covering metal piling, earthwork, and concrete, with a performance period of 365 calendar days. Financial terms are structured through a combination of lump sum and unit price items, with bid results ranging from approximately 2.4 million to 3.2 million dollars against a government estimate of roughly 2.03 million dollars. Multiple amendments were issued to refine the project, including updates to the Buy American Act requirements for steel sheet piling, modifications to wage determinations, and adjustments to measurement and payment criteria for excavation and scour protection.
