Market Experience
Kiewit is a leader in self-performing heavy civil construction. Because of Kiewit’s financial strength, we have invested in the right equipment and hired the best people to complete many large heavy civil construction projects. Our work includes tunnels, dams, spillways, reservoirs, foundations, mass transit stations and marine work. We specialize in cast-in-place concrete, post-tensioned concrete, structural steel erection, demolition, earthwork, pile driving, caissons and mechanical erection as well as contract mining and emergency repair services.
A Kiewit- led joint venture was awarded the contract to conduct the initial site clearing and excavations for this oil sands mega-project, located 70 kilometers north of Fort McMurray, Alberta, in the Athabasca oil sands region. To conduct the work required for this project, Kiewit has deployed more than 73 heavy haul trucks and 26 excavators, including an 800-tonne PC 8000 front shovel; 29 dozers; 10 loaders; 11 cranes; 6 packers; and more than 150 pickup trucks.
Imperial Oil’s Kearl Oil Sands project is located 70 kilometers north of Fort McMurray, Alberta, in the Athabasca oil sands region. A critical component of the overall schedule involves the completion of 740,000 cubic meters of trench excavation and the installation of 27,000 lineal meters of deep undergrounds piping.
In 2006, the Toba Montrose General Partnership awarded Kiewit an EPC contract for the design, procurement, construction and commissioning of two run-of-river hydroelectric facilities. At peak production there is enough hydroelectricity to power 75,000 homes.
Completing the longest micro-tunnel drive in North American history, a Kiewit-led joint venture is constructing Phase 2 of the $368 million Portland Combined Sewer Overflow project. Work includes excavation and lining of a 22-foot-diameter tunnel constructed 85 to 165 feet below ground and seven separate shafts located along the alignment.
Due to the long history of rockslides and land slippage, Kiewit Pacific Co. is constructing twin tunnels to bypass the Devil’s Slide portion of Route 1, so motorists can avoid these major slide areas. Using the New Austrian Tunneling Method, which relies on inherent rock strength for support, crews will construct the tunnels through granitic, sandstone and shale formations. The tunnels will be about 4,100 feet long, 30 feet wide, 22 feet high and 60 feet apart.
Kiewit is blasting, splitting, sorting and loading 145,000 tons of stone and transporting it by barge to repair the mouth of Columbia River Jetty. The barge travels through Puget Sound and the Strait of Juan de Fuca to the Pacific Ocean, down the Washington Coast and through the mouth of the Columbia before reaching its destination in Astoria.
