AC EC 20 1 3 E N G I N E ERIN G E XCELLEN CE AWARDS GRANDAWARDS Marlins Park, Miami, Fla. Walter P Moore and Bliss & Nyitray, Inc.— Tampa, Fla. National Synchrotron Light Source II, Long Island, N.Y. HDR Engineering—Alexandria, Va. This breathtaking retractable-roof design can withstand the most intense hurricane-force winds and has raised the standard of excellence for Major League Baseball stadiums. The new $515 million home of the Miami Marlins features a three-panel retractable roof, spanning up to 560 feet, mounted on a 150-foot-tall concrete support structure and weighing nearly 7,700 tons. The roof and support structure were designed to safely resist wind speeds up to 146 mph. Detailed wind studies conducted during the design process showed that keeping the panels slightly open during a wind event, rather than completely closed, reduced pressure by 25 percent, saving more than 1,000 tons of structural steel and more than $4 million in costs. The ballpark also achieved LEED Gold certification, making it the world’s first retractable-roof stadium to achieve this distinction. The new 600,000-square-foot research facility allows scientists to view a single atom with more clarity than ever before, helping to advance research in biology, chemistry, materials science and medicine. The facility generates light by accelerating a beam of electrons around a huge energy storage ring building at 99 percent of light speed. Through pioneering engineering design—and more than 41,000 cubic yards of concrete—the accelerator tunnel achieves precise vibration and temperature-fluctuation requirements. Nearly a half-mile in circumference and large enough to encircle Yankee Stadium, the storage ring produces the brightest and most intense X-rays in the world—more than 10,000 times brighter than its predecessor. The new research facility will play a critical role in new scientific discoveries. Catskill-Delaware Ultraviolet Disinfection Facility, Mount Pleasant, N.Y. Hazen and Sawyer/CDM Smith— New York, N.Y. The world’s largest ultraviolet disinfection facility replaces an outdated, century-old water treatment system and serves more than 9 million consumers in and around New York City. The new facility treats more than 2 billion gallons of water per day, providing protection from organisms that can cause gastrointestinal illness. The plant features 56 new UV vessels—more than at any other installation. The design also includes the largest flow-control and energydissipating valves of their type. The project demonstrates the feasibility and effectiveness of large-scale water treatment applications. 10 ENGINEERING INC. MAY / JUNE 2013 Lake Champlain Bridge Replacement, Crown Point, N.Y., to Chimney Point, Vt. HNTB Corporation—New York, N.Y. Designed in just 10 weeks, this new 402-foot-long network tied arch bridge replaces an 80-year-old deteriorating bridge and reestablishes a critical connection between Crown Point, N.Y., and Chimney Point, Vt. The emergency closure of the old Lake Champlain Bridge necessitated a 100-mile detour in some cases, and adversely affected economic conditions and commerce in the surrounding New York and Vermont areas. The new bridge features a center arch span that was built off site, floated in, then lifted 75 feet and connected—two years to the day after preliminary engineering began. The new bridge is more efficient, safer and marks a significant improvement to the region’s infrastructure and economy.
