2008 MultiFamily
2nd Runner Up

Built as a retirement community, it was important that Trinity Heights provide safe, comfortable, cost-effective living for older, fixed-income residents. ICF were able to provide lower utility bills, more safety, and quieter living quarters.

The design features brickledges, custom angles, ICF gables and various wall thicknesses, which were a challenge to build, considering the crew did the ICF install in high winds and freezing rains. 

The ICF walls support a tornado-proof, post-tensioned concrete roof, which is an important consideration for mobility impaired seniors in Iowa. The concrete roof also allowed 40-foot clear spans and considerable interior design flexibility.

The project received an “Excellence in Concrete” Award from the Iowa Ready-Mix Association, and was completed for a very reasonable $125 per sq. ft.
