The Digital Realty TOR1 - Phase II, Shell Upgrades project involved the installation of new structural steel columns, caissons and helical piles to support the new concrete slab-on-deck, as well as the removal of old roofing membrane and the installation of a new roof above the Digital Reality press room. Mechanical, Electrical and Fire Suppression systems were to be installed to support the newly renovated space.
The project also includes the installation of a new freight elevator that includes five stories and comes with a machine room and supporting steel structure. A new structural steel elevator roof overrun structure will be constructed complete with columns, beams and steel girt framing to accommodate the steel-insulated siding envelope.
To accommodate a new mezzanine within the existing shell of the vacant printing-press space, the column bay spacing is designed to take advantage of the existing press slab foundation system for support of new columns. These columns will run north and south using concrete infill slab constructed over top of the existing pile cap after the erection of the new columns. The new mezzanine floor system will be constructed using steel beams and columns to provide floor support made up of 38mm X 1.21mm steel composite deck, complete with 114mm concrete topping reinforced with 15m reinforcing steel at 305mm on centre, top each way.
