Denver Union Station Update #25

Current activity is all about building foundations for the bus terminal and the light rail station.

First, let’s look at the bus terminal. The six-inch-thick concrete mud slab is expanding through the area occupied by the foundations for the two escalators and the elevator. The water-proof membrane is being installed over the portion of the mud slab that was poured last week. Likewise, rebar is being installed over the membrane.

I’ll try to decipher the photo below that I took from the eighth floor of Glass House. To the right is the bare concrete mud slab. The dark area against the shoring wall is concrete covered by the membrane, which is covered by a very dense amount of rebar. Between the rebar area and the bare concrete is the area covered only with the membrane. It’s identifiable by the light-colored grid.  Work on the concrete, membrane, and rebar is continuing.

Considering the size of the rebar (it takes three men to carry one piece of it) and the fact that the floor will be four feet thick, it appears that the foundation will be a pretty solid.

Now for the light rail station. This part of the project is far less dramatic in scope than the bus terminal, but vital nonetheless. The following photo is from the Millennium Bridge and shows that the station  foundations are now approaching the Union Gateway Bridge (in the background). The ground surface will be raised to the tops of the concrete foundations/walls. Then the tracks can be laid, and the passenger platform can be built.

I’ve uploaded 13 new photos to our Denver Union Station page at JobSiteVistor.com so far this week. I expect more will follow as progress becomes visible.
