Cherne, a subsidiary of Kiewit, has been working on major projects at the Wood River Refinery since 1997. Most recently, Cherne oversaw construction and construction management for the CORE Project after successful completion of a new hydrocrakcer and ultra light diesel units at this same refinery location.
In addition to site work, Kiewit Offshore Services Fabricated 32 modules weighing 15,000 tons for the CORE Project.
For more than three decades, Kiewit has been constructing projects for the Vancouver Skytrain light rail system. Most recently, crews constructed several portions of guideway and elevated guidway on the Lougheed, Front Street and Grandview segments.
To ensure the stability of the suspension cables at Verrazano Narrows Bridge, Kiewit installed dehumidification systems and replaced bridge deck joints to prevent water infiltration. During construction, absolutely no damage was done to the cables due to extensive coordination and planning by crews.
Using a 1,270-milimetre-thick ice bridge for access, Kiewit completed the final pier on this $3.2 million, four-span steel girder bridge in September 1993. The 280-metre-long by 11-metre-wide bridge provides a link from a newly constructed pulp mill to vital timber reserves in northern Alberta.
Kiewit completed this $8.9 million project to replace a 34-year-old air traffic control tower one month ahead of schedule. At an elevation of approximately 7,000 feet, crews constructed a new control tower, base building, emergency generator building and fuel containment area.
This project consisted of renovating an existing 26,000 sq. ft., two-story building located in the heart of Omaha at 72nd and Dodge, which included a complete renovation of the interior space, all new mechanical and electrical systems, a new skin, an exterior media screen and a resurfaced parking lot.
This $550 million, 7-mile highway project included the challenges of balancing an aggressive job schedule with exceeding the tough erosion and sediment control standards of Maryland throughout several stream valleys and a 2-mile-long environmental special protection area.
