CAMBRIDGE, MASS. — CDM Smith was recognized with four awards from the Design-Build Institute of America (DBIA) 2013 National Design-Build Project Awards competition. Awarded projects include a nanofiltration water treatment plant addition, a stormwater and industrial process wastewater treatment system, a high-performance materials compounding plant, and a Stockton, Calif., Delta water supply project.

The 2 million-gallon-per-day (mgd) nanofiltration water treatment plant addition for the city of Dania Beach, Fla., won a National Design-Build Award in the water/wastewater category. This new treatment process-based expansion complements and integrates with the city’s existing 3-mgd lime stabilization water treatment plant to meet increased drinking water demands and improve finished water quality. The new membrane building shelters two, innovative four-stage nanofiltration membrane units, and includes operations, laboratory, administrative and maintenance facilities. The state-of-the-art water treatment plant is the first to receive LEED certification thanks to green initiatives that include optimizing energy performance equipment, using construction materials with high recycled content, and minimizing water use through xeriscaping and low-flow fixtures.

A stormwater and industrial process wastewater treatment system at Johnson Controls Inc.’s new lead-acid battery recycling center in Florence, S.C., also won a National Design-Build Award in the water/wastewater category. The integrated treatment facility treats process wastewater, generated by the recycling center, with chemical pretreatment, clarification and sand filtration to meet permit limits for safe discharge to the city sewer system. A portion of the treated effluent is reused in production, with excess discharged to the publicly owned treatment works. The new stormwater treatment system — built to contain a 100-year storm event — meets JCI’s unique zero discharge requirement by collecting stormwater from factory roofs, scrubber pads and pavement and holding it in a 2.3 million-gallon lined impoundment. Impounded water is treated for potential lead contamination with sand filtration and then reused as scrubber make-up water, which surpasses existing groundwater quality, displaces groundwater withdrawals and reduces spray nozzle maintenance.

The LANXESS high-performance materials compounding plant in Gastonia, N.C., won the Design-Build Honor Award in the industrial/process/research facilities category. The new compounding plant consists of a 35,000-sq.-ft., two-story production building and an administration/laboratory building with 10,000 sq. ft. of high-density raw materials storage warehousing, truck loading and unloading facilities, and large material silos. The plant places LANXESS close to U.S. automotive customers, which make up the largest high-tech plastics market in the world. Design-build delivery allowed CDM Smith to meet the client’s key objectives — budget, production capacity, plant operations and reliability, and an extremely aggressive nine-month construction schedule that was achieved through extensive collaboration to customize the building layout and utility infrastructure.

The Stockton, Calif., Delta water supply project won the Design-Build Merit Award in the water/wastewater category. The $220 million state-of-the-art surface water supply project, which provides a supplemental water supply under the city’s first water right, includes an intake and pump station, 18 miles of raw and treated water pipeline, ultrafiltration membrane water treatment plant, and an administration/operations building that is the city’s first structure to achieve LEED Gold rating. The innovative project pioneered the progressive (staged) design-build delivery method allowing the owner to fully participate in project development and decisions, establish a partnership with the designer and constructor, and competitively procure all elements of the project to achieve cost control and cost certainty.
