New foundations were poured, followed by the construction of structural steel platforms (also known as dunnage) that were rigged into place and installed prior to the rigging and setting of the new cooling towers. All crane and rigging work for the dunnage and the cooling towers was conducted “in the blind,” because the platforms and cooling towers were located on the opposite side of an intervening building from where the crane and trucking could be located. Structural steel connections consisted of both bolted and welded attachments. Associated work included decommissioning, demolition, and removal of obsolete equipment as well as architectural and structural renovations to accommodate the new equipment configurations. Interior work involved the demolition and reconstruction of architectural finishes involving the conference center, three conference rooms, and many corridors. Trades for this work included drywall, tile, acoustical ceiling, carpeting, and painting. Two restrooms were also renovated, along with modifications to a security lobby. Fire/Life Safety upgrades included the reconfiguration of sprinkler heads throughout the North Area and third-floor data center, as well as the installation of additional fire detection units, which were integrated into the fire alarm system. TMG also installed access controls at three separate entry points during Phase II.
