This 50-megawatt (MW) hydroelectric plant produces a non-consumptive, non-polluting and renewable form of energy for some 7,000 households. Built under an engineer-procure-construct contract, Kiewit completed the project with minimal impacts to the surrounding landscape.
TIC, a Kiewit subsidiary, was awarded the lump sum contract to construct an expansion to the existing natural gas compressor facility near Douglas, Wyoming. The scope of work consisted of all associated structural, mechanical, electrical, and instrumentation work.
A best-value selection process was used to select a Kiewit-led team to construct South Dakota's first design-build highway project. A 15-month construction window was established to minimize disruption on this 6.9-mile loop of Interstate 229. Despite one of the harshest winters in Sioux Falls' history, Kiewit finished 31 days ahead of schedule.
Kiewit was awarded the Phase I and Phase II contracts for a new nine-gate commercial aircraft terminal and Arrivals Hall at Ted Stevens Anchorage International Airport. With an emphasis on partnering, crews were able to overcome scheduling and security challenges to complete the project much earlier than expected.
The $11 million project involved installing 7,000 linear feet of pipeline, a two-million-gallon concrete reservoir, a booster pump station, consisting of five vertical turbine pumps, water treatment facilities, a new arsenic treatment system and a well development. To increase the station's water distribution pressure, crews constructed each zone with three 100-horsepower and two 75-horsepower vertical turbine pumps with variable frequency drives, which extend down 37 feet into a header, supplied with water from the bottom of the reservoir.
TIC was awarded the contract for the M&P and E&I work at an existing 28,000 TPD molybdenum mine that was brought back into production. Scope of work included demolition of existing structures, refurbishment of the primary and secondary crushing facilities, and construction of new facilities including a new mill and concentrator, ore storage and material handling systems, and a new main substation.
To meet the needs of a rapidly growing population, Western Summit, in conjunction with Carollo Engineers, designed and built a $43-million, 15 MGD expansion to an existing WTP serving the City of Mountain House, California, including a vast new subdivision. The entire project was completed in less than two years.
The $97 million Draper Light Rail Extension extends from the end of the existing North-South TRAX Line in Sandy, Utah southeast to the vicinity of the city hall in Draper, Utah. The project consists of 3.7 miles of ballasted double track and three stations with park and ride lots.
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.
