and risk reduction; and resiliency, such as structure durability, multi- hazard protection, and life safety and health. PCI also selects several projects for special awards that are judged on similar criteria to the building and transportation projects, as well as additional requirements including industry advancement, sustainable design, and designs using all precast concrete. These awards include the Harry H. Edwards Industry Advancement Award, The All-Precast Concrete Solution Award, and the Sustainable Design Award. Building projects The winner in the Government and Public Buildings category was the Phillip and Patricia Frost Museum of Science in Miami. The six-story museum features open-air parking covered by five stories of museum comprising approximately 250,000 square feet of interior and exterior space. The most prominent element of the design is the freestanding 67-foot-diameter dome, which houses the planetarium theater. Design- ers worked closely with Gate Precast Company to develop the concept using precast concrete as cladding and as the dome’s structure. The use of 3D modeling was vital to ensuring every piece fit perfectly and ad- dressing any errors in design before construction began. The dome cap, dubbed the Arctic Circle, was formed from two cap pieces combined to make a 30-foot-diameter keystone. Structural engineer of record was Donnell Duquesne & Albaisa, Miami. The Higher Education/University category had two co-winners: Capi- tol Federal Hall, The University of Kansas, Lawrence, Kansas; and University of Chicago Campus, North Residential Commons, Chicago. Capitol Federal Hall consists of two wings linked by a four-story glass atrium, which serves as a connector between the building’s major pro-
Innovations in precast concrete PCI awards 21 projects for design excellence.
The Precast/Prestressed Concrete Institute (PCI) announced the winners of its annual Design Awards program. This year the program, which is in its 55th year, recognized 21 projects with awards of excel- lence in design out of more than 100 project entries from producers, engineers, and architects across the U.S. “Our annual awards program is meant to challenge our industry to continue to push the envelope and to innovate in the design and pro- duction of precast concrete systems,” said PCI President Bob Risser. “The variety and quality of the projects our precast concrete producers and their partners in the engineering and architectural communities submitted for consideration this year demonstrate how versatile pre- cast concrete systems are for creating sustainable, cost-effective, and beautiful projects.” Projects are submitted in a variety of categories, including buildings, transportation, and special categories. They are judged by a panel of industry experts that includes precast concrete producers, engineers, architects, and construction and architectural industry media. The buildings and transportation categories are judged on aesthetic, structural, and use versatility; site, energy and operational efficiency,
