The U.S. Army Corps of Engineers has extended the deadline for bids for civil construction of an emptying basin for Charleroi Locks and Dam on the Monongahela River at Charleroi, Pa. Bids now are due Aug. 9.
The Corps’ Pittsburgh District previously called for bids by Aug. 8.
With federal economic stimulus funding, the Pittsburgh District allotted $17.4 million in 2009 for critical rehabilitation of Charleroi Locks and Dam, also known as Monongahela Lock and Dam 4. The Corps also took bids in 2009 for upgrades to the remote operation system of six of the nine navigation dams on the Monongahela in Pennsylvania and West Virginia. The Pittsburgh District has critical backlogged maintenance valued at $250 million dollars.
In the current solicitation, the Corps seeks fabrication of large precast reinforced concrete segments to form the outer shell of the 50-foot by 110-foot emptying basin. Tremie concrete is to be used as infill for the shell to solidify the structure, which will be located downstream of the dam and riverward of the new lock chamber river wall. The work is to require 810 days at an estimated cost of $10 million to $25 million.
A solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering Solicitation No. W911WN13B0005 in the “Keyword/Solicitation #” box.
