Along Lake Michigan's eastern shoreline, the Cook Nuclear Plant has been generating atomic energy for more than 30 years. When a permit was granted by the Atomic Energy Commission to construct the plant in 1969, became one of the largest construction projects in the state. It cost $1.3 billion to build in the 1970s and employed more than 2,000 construction workers. With two pressurized water reactor units, the plant's 1,048-net-MW Unit 1 and 1,107-net-MW Unit 2 produce enough electricity for more than 1.5 million homes.

At the plant in Bridgman, Mich., which is owned and operated by American Electric Power, a modular office is currently being added to the top of an existing building. The modular office will serve as a break area for employees during outage work at the plant. Imperial Crane Services Inc., Bridgeview, Ill., was contracted to provide the heavy lifting for the job.
