Constructed by a Kiewit-led joint venture, this $100 million, 10-lane Leonard P. Zakim Bunker Hill Bridge is the world's widest cable-stayed structure. The new bridge opened to traffic in March 2003 and is the highlight of Boston's multi-billion dollar “Big Dig” Central Artery/Tunnel project.
The Antelope Station Grid Switching Expansion Project will allow an existing generating station to switch between the SPP and ERCOT grid systems. Kiewit Engineering and Design is designing the switch to a grid configuration consisting of a single-breaker, double-bus.
Kiewit completed the engineer, procure, and construct contract for a wet front end for an existing ore processing facility at the Cloudbreak iron ore mine. The improvements allow the mine to process wetter ore with more fines than the facility could previously handle.
The scope of work included demolition of the existing hopper bottom, metal roofed reservoir, the construction of a new 20 MG cast-in-place reservoir, installation of chemical feed piping, level sensors, transmitters and associated conduits and control wiring.
The J. James Exon Regional FBI Headquarters is a multi-building, secure campus that includes a 97,800-square-foot office building, 49,400-square-foot parking garage and a 14,500-square-foot annex building. The main four-story building achieved LEED® Gold certification and incorporated numerous sustainable design features.
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.
To decrease the cost of hydroelectric power and increase the demand for service, Kiewit completed this bid-build contract to expand the Healey Falls Generating Station. Located about 15 kilometers north of Campbellford, the generating station includes a new unit in a spare bay inside the existing hydroelectric power plant once complete.
