LAUSANNE, Switzerland (AP) — The first stone for the new IOC headquarters was symbolically laid on Tuesday.

The 200 million Swiss francs ($200 million) project will allow the International Olympic Committee to house all 600 employees under one roof.

Ground clearing on the new site is scheduled to begin in April, and the new building is expected to open in 2020.

Staff will move to temporary offices in the Lausanne suburb of Peuilly in February.

The IOC has been based in Lausanne for 100 years.
