Featured Gold Winner: Grunau Metals, Oak Creek, Wisconsin

 

Description of project: This stair was designed to mimic medieval gothic style wrought iron architecture and was attached to the exterior of a castle-like turret. Key features were chosen through coordination between the design architect, GC, and fabricator. The final look was to incorporate minimal structure for a skeletal appearance while maintaining load calculations. To compensate for irregularities in the radius of the poured concrete foundation wall, the Grunau Metals team worked closely with the concrete contractor and obtained laser scanning of the cured wall after forms were removed. The Grunau Metals team then used the data with their own Trimble equipment to project points on our fabrication shop floor, engineering a steel turret, which dimensionally matched the concrete version on the field. They erected the entire stair structure based on the field data points collected. After fabrication, it was disassembled, shipped for galvanizing, and then re-assembled in sections at the job site. Not one piece required rework for erection.
