Structural design for 12 floors above ground and four parking levels below ground. The building has a 40' x 90' atrium with a skylight. The building incorporates the historical Greyhound Bus Terminal. This required use of 70' long post-tensioned transfer girders to transfer the column loads over the terminal. The foundations are deep caissons. The building is close to the metro tunnel which required special structural analysis so that the tunnel is not overloaded. The caissons adjacent to the tunnel were drilled with bentonite slurry.
