| Colorado plant wins 2006 Design-Build Excellence Award  Black & Veatch announced that the Nelson-Flanders Water Treatment Plant, completed by the Black & Veatch-Western Summit Constructors Inc. joint-venture design-build team for the city of Longmont, Colo., earned a 2006 Design-Build Excellence Award from the Design-Build Institute of America (DBIA) in the "water over $15 million" category. The new plant provides high-quality drinking water to meet the increased demands of a growing population and economy. Treatment works include a raw-water reservoir, two-stage flash mix, three-stage flocculation, high-rate lamella plate settlers prior to dual-media filtration, and chemical disinfection facilities. The design incorporates gravity-driven conveyance to maximize efficiency. The plant was designed and built not only to meet present needs but also to accommodate future development and regulatory requirements.The award was presented at the DBIA Annual Conference and Awards Ceremony held recently in Nashville, Tenn. Sharing a picturesque rural site with a 19th-century dairy farm, the 30-million-gallon-per-day water treatment facility sits in harmony with history and nature. Designed to complement the adjacent structures, the modern treatment plant resembles a historic barn while dry-chemical storage facilities model silos. The project team worked closely with the community to preserve trees and wildlife corridors, devoting special attention to provision of roosts for migratory hawks and relocation of prairie dog colonies. The integrated design-build approach and productive partnering between the city and the design-build team enabled a collaborative permitting process. Because this process began immediately and continued through phased design and construction, the team was able to keep the project on track while securing dozens of diverse permits from multiple entities. The treatment plant began operation three months ahead of schedule for a cost that was $2.8 million under the $43 million budget. write your comments about the article :: © 2006 Construction News :: home page |
