PROJECT OVERVIEW
A nine-story mixed-use building was converted to a total–precast concrete structure. By using 69-foot-long Ultra-high-performance concrete (UHPC) beams, interior columns were eliminated, allowing open sightlines, more rentable space, and the ability for adaptive reuse in the future.

PRECAST SOLUTION
UHPC has been around for more than 30 years, but the prohibitive cost of proprietary blends kept it from widespread adoption. With the completion of research and development sponsored by PCI, this material, with its extremely high tensile strength and durability as well as compressive strengths over 17,000 psi, is finally being used. Unlike self-consolidating concrete, which was introduced in the 1980s and enabled manufacturers to produce precast concrete more efficiently, this technology can transfer value directly to the owner. |
