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.
Gulf Intracoastal Waterway (GIWW) West Closure Complex
Belle Chasse, La.
The GIWW West Closure Complex is a $1 billion hurricane storm surge (flood) protection facility for the city of New Orleans and surrounding areas. This Early Contractor Involvement (ECI) contract included one of the world’s largest interior drainage pump stations and one of the nation’s largest navigable floodgates (225 feet). The pump station has 11 units and is capable of discharging storm water at a rate of 19,140 cubic feet per second.
Yucca Mountain
Nye County, Nev.
A Kiewit-led joint venture excavated over 40,000 ft. of an 18- and 25-ft.-dia. tunnel to develop the Exploratory Studies Facility (ESF). The ESF was constructed to determine the suitability of storing high-level nuclear waste. A unique feature of the project was the use of a "mapping gantry" to provide safe access for project geologists and scientists during excavation.
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.
Table Rock Auxiliary Spillway Phase 1
Branson, Mo.
By partnering with the U.S. Army Corps of Engineers, Kiewit finished this project four months ahead of schedule. Phase I involved excavating, blasting and preparing the spillway's foundation. Because blasting occurred beside the existing dam and near a heavily-traveled highway, expertise in controlled blasting and seismic monitoring was essential.
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.
East Dam
Hemet, Calif.
East Dam is one of three dams constructed for the Metropolitan Water District of Southern California's Eastside Reservoir program. Holding more than 260 billion gallons of water, the reservoir doubles Southern California's surface storage capacity. At 180 feet high and 1,200 feet wide at the base, East Dam is the longest of the three dams.
Magnolia Trunk Sewer Rehabilitation
Orange County, Calif.
This $15 million project will perform condition assessment, design, and construction to rehabilitate a portion of the existing Magnolia Trunk Sewer in the cities of Fountain Valley, Westminster, and Garden Grove, CA.
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.
Bonneville Fish Bypass
North Bonneville, Wash.
This award-winning project allows migrating salmon and steelhead trout to bypass the Bonneville Dam and travel safely through the Columbia River. Kiewit Pacific Co. ultimately constructed a 3,000-ft.-long, high velocity concrete chute with 25-ft.-high walls to transport fish around the dam and through a new channel outfall.
