Second Place (tie): Vaughn Concrete Products Vertical Axis Wind Energy Turbine Structure Vaughn Concrete Products developed this precast structure, which consists of four stacked precast A-panels. The curved airfoil sections are 12 feet wide by 34 feet tall and weigh 51,000 pounds each. The three precast units channel wind into the turbine to create an energy system that generates power. After one hour of 33-mph winds, the unit generates enough power for 20 Wyoming homes. Third Place (tie): Hanson Structural Precast Pacific Element Lofts Hanson Structural Precast Pacific created this luxury urban multifamily structure in Irwindale, Calif., using precast concrete “moment” framing. The double-tee construction used often in parking garages is employed here to create a building with high strength that is capable of supporting long spans. Third Place (tie): Modern Precast Concrete Comcast Center Project Modern Precast created the precast for a tuned Liquid Column Damper system in the Comcast Building in Philadelphia – the 13th tallest building in the United States. The liquid column damper is a system in which a body of water is tuned to move in sequence with the swaying of the building. The precast panels for this system were installed more than 975 feet above ground. Third Place: Garden State Precast Inc. Target Retail Abutment For this project in Hackettstown, N.J., Garden State Precast Inc. match-cast two abutments in three 70-ton sections, along with nine wingwalls. Each of the six post-tensioned sections displayed a footprint of 9½ feet by 20 feet. Due to the size of the precast elements and the long reach required, a massive 650 ton mobile crane was used to set the pieces. The abutments and wingwalls were installed in just two working days. Second Place: Granite Precasting and Concrete The Big Gulch Project For the Big Gulch Trunk Sewer in Bellingham, Wash., Granite Precasting constructed the components of a diversion structure that diverts excess water from the existing culvert in order to prevent flooding and erosion while protecting the fish habitat. INSTALLATION OF SHERMAN-DIXIE'S FIRST-PLACE CUP AWARD BRIDGE DESIGN TOOK JUST TWO DAYS. UNDERGROUND CATEGORY First Place: Sherman-Dixie Concrete Industries Inc. The Missing Link Sherman-Dixie created a four-sided box culvert system for the Henderson County Road Department that spanned a 26-by-12-foot section of county road in rural Henderson County. Hydraulically, structurally and aesthetically, this was an enormous improvement from the failed twin corrugated metal pipe structure that it replaced. The entire structure was placed in two days – a fraction of the time that would have been required for a typical three-sided installation with cast-in-place footers and much quicker than the 60 to 90 days of road closure that would have been required by a built-in-place bridge.
