Association honors city tank designs
The Portland Cement Association, Skokie, Ill., presented Concrete Tank Awards to San Diego and Coral Springs, Fla., recognizing the cities’ attention to environment and architecture.
* San Diego Metropolitan Wastewater Department. The city received the Distinguished Environmental Consideration award for design and construction of the Miramar Reclaimed Water Storage Tank. The 9-million-gallon tank incorporates base and top seismic connections to provide maximum ductility during an earthquake. It has 23-foot high walls, is 260 feet in diameter and has a cast-in-place concrete floor, roof and core wall. The wall is 15 inches thick and was created in 46-foot-wide consecutive panels with 5,000-psi concrete. Berryman & Henigar, San Diego, was the project’s prime contractor; Simon Wong Engineering, San Diego, served as subcontractor; and DYK Incorporated, El Cajon, Calif., built the tank.
* Coral Springs, Fla. The city received the Distinguished Architectural Treatment award for construction of a 1.35-million-gallon water storage reservoir. The tank has 25-foot, 7-inch high walls and is 95 feet in diameter. Precast capitals were installed with stainless steel rods, and columns and horizontal bands were installed through conventional shotcrete construction, a process in which the concrete is sprayed onto the surface rather than cast. The bands were painted with a contrasting color to create pleasing aesthetics. Camp Dresser & McKee, Cambridge, Mass., and Crom Corp., Gainesville, Fla., built the tank.
