The US Army Corps of Engineers (USACE), Pittsburgh District is the Owner of the Charleroi Locks and Dam 4 Emptying Basin Project, located on the Monongahela River in Monessen, PA. The Emptying Basin is a component of the new lock chambers and acts as a diffuser while the chambers are dewatered as part of the locking process.

The project scope involves building seven, separate precast concrete structures offsite, then loading the segments onto barges, delivering them to the job site, and assembling them into place, under water, using floating A-frame cranes. The concrete segments were “match cast” at an offsite facility upstream of the Locks and Dam in order ensure their fit-up in place underwater.
