LAUSANNE, Switzerland (AP) — The International Olympic Committee plans to renovate its Swiss headquarters to bring all departments and staff under one roof.

The IOC has opened a bid process to hire an architect to design the extension of the lakefront building in the Vidy section of Lausanne.

The IOC says a final decision on the project will be made by the executive board in December.

Sandrine Tonge, an IOC spokeswoman, says "the idea is to extend and transform the existing headquarters to centralize the IOC's operations."

She says IOC staff work in five different locations in Lausanne "resulting in a loss of synergy and additional operating costs." About 150 people work in Vidy, with another 300 at other locations.

The main building was built in 1986 and a new annex added in 2005. The headquarters sustained major flood damage in November caused by a burst water main.
