Alten Construction of Richmond announced it has broken ground on the $13.3 million Bill and Adele Jonas Center on College of Marin's Indian Valley Campus.

The new one-story, 10,800-square-foot center will utilize much of the existing structures and foundations of the campus’ Building 19. The new facility will provide space for a 710-seat banquet hall, as well as a raised platform, restrooms, prep kitchen and support space. The project also includes the addition of a one-story lounge space. The Bill and Adele Jonas Center will be used for college-sponsored events, programs and training.

Alten also will make modifications to the campus’ existing 4,800-square-foot Building 18. Updates to the one-story building include the design of a new commercial kitchen, laundry room, storage, office and meeting room spaces and the replacement of existing windows and exterior finish.
