Ameren Energy SCR Installation
Coffeen, Illinois
Lift Engineering

Installation of two new Selective Catalyst Reduction (SCR) units posed major hurdles at this 900MW power plant. Making the tie-in of the new SCR units in a limited plant shutdown period and under severe site constraints required an innovative approach to the demolition of existing ductwork. The project team needed a way to lift large, heavy preassembled sections (up to 400,000 pounds and the size of a two-story house). Ruby+Associates developed an integrated approach to the demolition operations that maximized use of the existing support structure, expedited the overall project schedule and minimized disruption of plant operations. The project was completed within the budget and schedule established by the owner, entitling the general contractor to the full amount of the early completion bonus stipulated in the contract.
