The Post-Tensioning Institute, a nonprofit organization for the advancement of post-tensioned, prestressed concrete design and construction, has announced the winners of its 2008 awards competition.
The Project of the Year, Award of Excellence for 2008 went to the new Guthrie Theater center in Minneapolis. Submitted by post-tensioning supplier AMSYSCO Inc., the project was entered in the mixed-use building category and includes three theaters and a 1,000-space parking garage. The post-tensioned concrete framing system provided the most effective solution for the main theater and parking structure. The main theater’s framing system consists of an 8-inch-thick sloping slab supported by a radial/circular network of beams and cantilevered girders on five tiers. This unusual design required a high degree of technical expertise in post-tensioning to accommodate the heavy live loads and large, column-free areas. For the traditional six-level parking structure, an encapsulated post-tensioning system provides maximum corrosion protection and longevity. Other project team members include Jean Nouvel and Architectural Alliance (architects), Erickson Roed & Associates (engineer) and McGough Construction Co. (contractor).
Other winners included: Suncoast Post Tension Ltd., Commercial Building; Cary Kopczynski & Co., Residential Building; Forell/Elsesser Engineers Inc., Award of Excellence, Buildings: Repair/Rehabilitation and Strengthening; Tipping Mar & Associates, Award of Merit, Buildings: Repair/ Rehabilitation and Strengthening; Suncoast Post Tension Ltd., Award of Excellence, Slab-on-Ground; GSI Post-Tension, Award of Merit, Slab-on-Ground; and Walter P Moore, Award of Excellence, Parking Structure.
