Permanent Canal Closures and Pumps (PCCP)
New Orleans, La.
The Permanent Canal Closures and Pumps project (PCCP) was a fixed-price, design-build project that provided a permanent, more sustainable solution for reducing the risk of a 100-year level storm surge entering the outfall canals throughout the city of New Orleans.
Texas Street Pump Station
San Bernardino, Calif.
The project involved construction of a new pump station and 0.5 MG reservoir, de-chlorination facility, electrical ductbank, and roadway improvements.
Olivenhain Pump Station
San Diego, Calif.
This $24 million project involved constructing a building to house three 2,500-HP pumps and their associated piping. The interconnecting pipeline outside the pump station was also included in the standard bid-build contract.
NSR Pump Stations
Sacramento, Calif.
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.
Val Vista Transmission Main Rehabilitation and Replacement
Phoenix, Ariz.
The Val Vista Transmission Main Rehabilitation and Replacement project, delivered in seven GMP’s, was the largest project of its kind in the United States., The project was developed to trenchlessly rehabilitate a critical piece of infrastructure that transports 220 MG of drinking water to as much as 60 percent of the population in Phoenix, Arizona. The project involved the rehabilitation of 30,000 feet of 96-inch to 72-inch prestressed concrete cylinder pipe by means of a split-can, steel slip lining.
Bitter Point Pump Station
Newport Beach, Calif.
This $20 million project involves replacing the existing sewage pump station with a new upsized 39 MGD pump station. Construction on the new pump station includes a below-grade wet-well and dry-well, and an above-ground electrical room.
Central Feeder
San Bernardino, Calif.
This $61 million project involved the design and construction of a water transmission system. The success of the shutdown, tie-in, and restart was due to the project team's well planned coordination and communication with the local agencies and community.
Gilbert Reservoir and Pump Station
Gilbert, Ariz.
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.
Hollywood Hills
Hollywood, Calif.
Kiewit Pacific Co. constructed the world's largest prestressed concrete tanks. The $86 million Hollywood Hills Quality Improvement Project consisted of two 30-million-gallon underground water storage tanks and a 1-mi.-long tunnel bypass system to provide safe drinking water for nearly 500,000 customers in the Hollywood area.
Lake Mead Intake No. 2
Las Vegas, Nev.
A Kiewit-led joint venture was selected in December 1997 to construct a key component of the new $2.2-billion water delivery and treatment system for the Las Vegas valley. This $83-million project involved constructing a 12-ft.-dia. intake shaft positioned 240 ft. below Lake Mead's surface, capable of handling 600 million gallons of water per day.
