The Icehouse is a multi-use office/retail building located in an architecturally-sensitive historic section of downtown Denver.  As part of the design-build team, VSL provided engineering of the parking level slabs, furnished the post-tensioning system, and installed the post-tensioning and mild reinforcement.

Phasing of the structure was unusual in that the three levels of below-grade parking were constructed as the steel superstructure was erected.  Height limitations, shallow groundwater, and long spans resulted in the decision to use a post-tensioned wide/shallow beam system because of its minimal depth and overall economy. Special detailing was required for stressing of the tendons since the edges of the slabs were not accessible. VSL's early involvement in the planning of the project proved to an important element in the project's success.
