Utilities, HVAC and Roofing Continue September 6, 2011 By stewartperry Our team made great progress on the sanitary sewer. We’re close to connecting the piping to the building. HVAC work is moving along. Rooftop curb installation is complete, and we are ready to commence work on the building duct work. We are moving ahead with the fire sprinkler installation. We have completed brick gables with step flashing and are now ready for truss decking. The exterior sheathing is nearing completion, readying the building for door and window installation. Roof material is stocked and ready for installation.
