With Structural Steel Complete, Walls and Veneers Are in Formation August 23, 2011 By stewartperry Last week, we set the roofing trusses on the US Steel Realty building. All trusses are now in place, making the roof ready for decking. Our team has installed the main water tap, meter vault and electrical service conduits. In the basement, we have stocked sheet rock. Wall framing will start as soon as all utilities are roughed-in.
