Listed as a National Historic Landmark, the Wyoming State Capitol, originally constructed in 1886, underwent a major restoration. This project included renovation and restoration of the historic 130,000 SF State Capitol, renovation of the 360,800 SF Hershler Office Building, and modifications to the underground connector gallery that serves as a tunnel for the Capitol Square. The project also includes a new central utility plant that accommodates all new mechanical, electrical, plumbing, life safety, and ADA upgrades. Although renovations were necessary, the restorations maintained the original appearance and historical features all while re-configuring the space to accommodate modern offices, state of the art technology, additional meeting rooms and improved circulation.
