A Kiewit-led joint venture completed three contracts from January 2000 to March 2003 to construct portions of this diamond mine south of the Arctic Circle. A major feature of the project was the 3.9-kilometre water retention dike that encircles the diamond deposits — the first dike of its kind constructed in Canada.
Kiewit Southern Co. was awarded the $11 million project to design and construct the Pembroke Pump Station. The team constructed an at-grade precast panel pump station, four 40-cubic-feet-per-second pumps with 30-inch-diameter expansion joints, back-flow gates and butterfly valves that are connected to a 64-inch-diameter steel header pipe.
The Central Artery/Tunnel has the capacity to carry 250,000 daily vehicles. To ensure the safety of motorists, crews installed a system-wide security system that includes perimeter video surveillance, an access control system, an instruction detection system, a security operator console, motion detection and telephone communication.
The project consisted of building a 5,920 square foot FEMA rated shelter addition adjacent to PayPal's existing building. The shelter space was designed to withstand two concurrent F4 tornados while occupying up to 1,000 employees in the event of a severe weather event.
Completed nearly one year ahead of schedule, the $28 million I-20 Lane Replacement project involved replacing 13 miles of east and westbound Interstate 20. Additional work included roadway demolition and shoulder widening while maintaining traffic through this heavily traveled corridor.
From 1993 to 2002, crews completed four contracts totaling more than $64 million for the DART Light Rail Starter System and the North Central and North Eastern Extensions. The main scope of work involved constructing the train control, central control and communication systems. Crews also installed and tested an automatic block signal system for more than 44 miles of double track. System elements included automatic highway crossing warnings, train stops, and train-to-wayside communications.
The Texas Department of Transportation awarded the DFW Connector contract to a Kiewit-led joint venture. The $1.02 billion project scope included the development, design and construction of the 8.4-mile initial phase of the ultimate 14.4-mile project. The project reduces congestion at the confluence of two of the area's most heavily traveled highways and ease access into DFW International Airport. Crews rebuilt portions of four highways, two interchanges and five bridges, ultimately doubling the capacity of the existing highway corridor.
With this project, the Nebraska Medical Center merged two facilities into a single state-of the-art healthcare center. The Center contains four core functional areas: emergency, surgery, radiology and a neonatal intensive care unit (NICU). The combined capabilities of the facility make it the largest emergency department in the Midwest.
