Concrete Cutting & Breaking Co. (CCB) undertook the precise removal of approximately 6,500 tons of concrete for the full rehabilitation of the Dresden Island Lock and Dam. This project was unprecedented in scope and complexity, particularly the removal of valve recesses, which had never been performed on any lock and dam before. Utilizing multi-method concrete cutting practices, CCB worked around the clock to meet strict deadlines. The 650 LF lock chamber required continual work across all areas, with CCB collaborating closely with the client to develop an effective demolition plan. This plan included complex lifting and rigging operations combined with precise cutting processes, resulting in lifts ranging from 5 to over 50 tons.
Locks are crucial for resource transportation in the U.S. economy, making timely and accurate project completion essential. Despite the unique challenges, CCB successfully completed the project, allowing the lock to be returned to industry users on schedule.
