The state Office of General Services is scheduled Monday to demolish the first set of buildings at the W. Averell Harriman State Office Campus as part of the site's redevelopment into a mixed-use technology and business park.

Ritter & Paratore Contracting Inc. and LaCorte Cos. Inc. are slated to begin the demolition of Buildings 1 and 1A, which formerly housed the state Department of Civil Service. Civil Service has relocated to the newly renovated Alfred E. Smith Building in downtown Albany, N.Y.

The state will spend $240 million plan to covert the 330-acre campus into a "research and development technology park. The master plan calls for 600,000 square feet of new Class A office space, 1 million-square-feet of renovated office space, 400,000-square-feet of new research and development space, and 200,000-square-feet of neighborhood retail space, along with a learning center and hotel. The plan also calls for 850 residential units such as townhouses and condos.

When Gov. George Pataki first announced the plan in 2002, there were 10,000 state workers on the campus. The goal was to move all but 1,000 state jobs off the campus and create 8,000 new private-sector jobs.
