The $71 million Robert B. Diemer Filtration Plant project was to establish a seismically stable foundation for a new ozone generation facility. Before any production work could begin, a large amount of demolition work needed to be completed, including the existing maintenance building, fueling station, asphalt parking area and duct bank runs.
The Woodbridge Energy Center (WEC) is a 700-megawatt gas-fired power plant located on the site of an abandoned chemical plant. It will generate enough electricity to power more than 600,000 homes while increasing grid reliability. In an effort to stay eco-friendly, as well as cutting edge, the facility will use the most advanced generation technology today and, when complete, WEC will be one of the nation’s cleanest and most efficient generation stations.
The passenger tunnel at Dulles International Airport allows travelers to move more efficiently through the fast-growing airport. Kiewit excavated the tunnel under a live taxiway using New Austrian Tunneling Method. The completed tunnel is lined with PVC waterproofing and reinforced cast-in-place concrete and is equipped with escalators and moving walkways.
In November 2014, Kiewit Mining Group entered a 10-year contract to provide contract mining services for the Walnut Creek Mine. The operation includes an 80-cubic-yard dragline, a 20-cubic-yard mass excavator, an 18-cubic-yard hydraulic backhoe and a fleet of 150-ton end-dump trucks to move more than 20 million cubic yards of material annually. The captive lignite operation can produce more than 2 million tons of lignite per year and incorporates a blending program that provides consistent quality lignite to fuel two 150-megawatt circulating-fluidized-bed power plants.
Working at a depth of 80 feet, crews from Kiewit Pacific Co. pumped groundwater from the excavation site at a rate of 14 million gallons per day to construct New Natomas and South River Pumping Stations. The scope of work at each site involves excavation support, dewatering, constructing new below-grade and at-grade concrete structures and installing mechanical equipment.
The Hixson-Lied Science Center is a 150,000-square-foot center intended to be Creighton University's main entrance on the north side of campus. The center includes faculty and staff offices and classrooms for the schools of medicine, pharmacy and nursing, and the undergraduate departments of chemistry, biology, physics, environmental science and atmospheric science.
Indianapolis Power and Light Company (IPL) provides electric service to more than 470,000 users in the area and surrounding communities, with Petersburg and Harding Street Plants, the company’s two biggest plants, accounting for a majority of that generation. In order to meet EPA Mercury and Air Toxics Standards (MATS) compliance, IPL is retrofitting five units at these sites with new environmental control equipment.
