All interior structural steel framing has been installed to infill the last remaining hole in the core of the building, from Level 0 all the way up to the roof. The underside of the metal deck forming the floor plates has been sprayed with fire proofing. Concrete has been placed over the metal deck on all levels to form new floors. Currently, a large crane is onsite erecting the last of the heavy structural steel beams and columns to form the roof penthouse that will house mechanical and electrical equipment. The crane is also setting curved tube steel “ribs” that will form the new structure for the roofs that will cover the former atriums, to make them indoor spaces eventually when the roofing is installed in the next couple of months.
