CHEYENNE, Wyo. (AP) — The State Building Commission has approved spending $400,000 on initial design work for renovation of the state Capitol's interior.

The renovation of the building has been estimated to cost up to $50 million. The Legislature would need to approve money for the renovation work, but it has already set aside about $87 million for the project.

State construction manager Rich Cathcart says the renovation is needed to repair and improve the Capitol's wiring, heating, cooling and fire suppression systems.

The commission consists of the state's top five elected officials. Tentative plans are to start the project in 2015.

Capitol employees would be moved temporarily to the Herschler Building next door, and one session of the state Legislature would have to be held elsewhere outside the Capitol because of the project.
