A dozen arched steel trusses -- a 180-by-90-foot section of the roof's steel framework -- toppled about 11:30 p.m. April 17 and temporarily stopped work on the $756 million project at Mount Vernon ...

The truss extends beyond the glass doors to support the glass roof as a canopy. A series of 120 x 80mm RHS purlins, each with a row of 60mm-diameter steel bosses welded to it, runs over the trusses.

A construction worker died earlier this week after being hit by a steel truss while working on a high school gymnasium, the Michigan Occupational Safety and Health Administration (MIOSHA) announced.
