The Antelope Station Grid Switching Expansion Project will allow an existing generating station to switch between the SPP and ERCOT grid systems. Kiewit Engineering and Design is designing the switch to a grid configuration consisting of a single-breaker, double-bus.
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.
Part of restoring the Everglades to an ecologically balanced condition by reducing levels of phosphorous in the water created from farmland storm water run-off, the $2.3 million project included installing a new intake and pump station in Palm Beach County, Fla. Due to the remote location in the Everglades, Gilbert Southern Corp. maintained an on-site office throughout construction.
Kiewit exceeded expectations by completing this fast-track project in just 10 months. By working simultaneously on three sections of the road, crews were able to maximize productivity and complete the project early. The reconstructed stretch of U.S. 11 provides a safer route for motorists with more lanes, expanded shoulders and extended merge lanes.
In less than 18 months, a Kiewit-led joint venture completed Phase I of the Greater Toronto Area's first bus rapid transit system. The team developed innovative design solutions to meet the project's technological challenges including real-time electronic bus arrival displays and a computer-aided dispatch transit control center with GPS.
KCP&L and Westar Energy selected the team of Kiewit and Sargent & Lundy LLC to engineer, procure and construct the retrofit to the 1500 MW plant. The La Cygne Generating Station Environmental Retrofit Project includes the installation of two Hitachi wet FGD scrubbers and new Hamon fabric filters on Unit 1 and Unit 2; and a selective catalytic reduction (SCR) system, low-NOx burners and over-fire air system on Unit 2 of the facility.
The Toyota Elephant Passage Exhibit at the Denver Zoo is the first LEED® Platinum certified exhibit in the country. As part of the project scope of work, Kiewit demolished 17 existing buildings and redeveloped approximately 10 acres of Zoo space. The exhibit features six expansive outdoor yards, three animal crossings and more than 1.1 million gallons of water for the exhibit animals to enjoy. A unique gasification plant, which is designed to convert animal waste into a power source, was built adjacent to the exhibition area.
This $22 million emergency repair contract provided structural stability to Graving Dock #3 after a sheetpile cell catastrophically erupted. Kiewit successfully dewatered the dock and strengthened the cell. The team's impressive performance led to a follow-on contract to provide permanent repairs to the dock.
Kiewit completed a $33.5 million contract to repair El Portal Road in Yosemite National Park after several days of heavy, warm rains combined with record flows in the Merced River caused extensive flooding and washed out the road in 19 locations.
Kiewit Pacific Co. completed Phase II of a $42 million contract to improve water quality and plant operations at the Penitencia Water Treatment Plant. The project scope included the construction of a two-story, 7,200-square-foot ozone generation building, an ozone contractor structure and a liquid oxygen storage and vaporizer structure.
