Construction workers attend to steel beams Jan. 14 on the outside structure of a building at the new Westinghouse Electric headquarters in Cranberry Township. The first wave of employees is expected to move in by summer. A total of 3,000 employees will occupy the more than 800,000 square feet of office space on the company's campus by 2010.

CRANBERRY TWP — The final structural beams were placed in January to top off buildings 2 and 3 as construction progresses on the new $216 million Westinghouse Electric headquarters.

The first wave of employees is expected to occupy the first building this summer, said Vaughn Gilbert, spokesman for Westinghouse.

The remainder of the more than 3,000 employees are expected to be in the remaining buildings by 2010.

"Turner is proud to have reached this significant milestone for the new Westinghouse Electric Co. headquarters campus," said Joe Milicia, vice president and general manager of Turner's Pittsburgh office. Turner Construction is the project general contractor.

The company hosted a fundraiser for food banks and the Butler County Veteran's Administration Hospital to celebrate the project's milestone.

The first topping off occurred in August on the first 434,000-square-foot building that will be included in the executive offices in the Cranberry Woods office park off Route 228.

About 3,300 tons and more than 6,000 pieces of steel were used in the first building, and another 3,300 tons were erected for buildings 2 and 3.

The entire Westinghouse campus will consist of 844,595 square feet of office space on 83 acres.

Construction on all three of the buildings now is concentrated on finishing their exteriors and interiors.

Westinghouse recently announced it has partnered with the Shaw Group's Power Group for a contract with Progress Energy Florida, a subsidiary of Progress Energy, to provide two Westinghouse AP1000 nuclear power units at its Levy County, Fla., site.

The licensing process, once completed by the federal Nuclear Regulatory Commission, gives Progress Energy the option to construct and run two units at the Levy County site. Westinghouse in 2008 signed two such contracts, one with Georgia Power at a site near Waynesboro, Ga., and the other with the South Carolina Electric & Gas and Santee Cooper in Jenkinsville, S.C.

Additionally, the AP1000 has been identified as the technology for eight additional nuclear plants that could be built in the United States.

In July 2007, Westinghouse and Shaw signed contracts to provide four AP1000s in China, where initial construction is under way.
