Davis Erection Co. was selected by Hitachi to finish the fabrication of the top girders at the Mid American Energy 790 megawatt coal fueled Power Plant Addition., located in Council Bluffs IA.
The top / bottom flange and stiffener plates had to be welded to the 114' long x 24' tall x 1 ½" thick web. Most of the welding was done using the sub arc process. There was over 1,650 L.F. of weld on each girder. After one side was welded the girder had to be rolled over to weld the other side. The heavy girder weighed in at 200 tons (400,000 lbs.)
The project was completed on schedule.
