The Oregon State Capitol was designed by the New York architectural firm of Trowbridge and Livingston in association with Francis Keally and completed in 1938. Erected in the Modernistic style, the Capitol was sensitively enlarged in 1977 by the Portland firm of Wolff Zimmer Gunsul Frasca in association with Pietro Belluschi. Constructed of reinforced concrete, the building is distinguished by angular, unadorned exterior elevations and a massive, ribbed lantern all sheathed in brilliant white Vermont marble.

In 2008, as part of the team creating a new Master Plan for the Capitol, PMA conducted a full exterior condition assessment of both the main building and east and west wings. On Labor Day 2008, an exterior fire damaged the Vermont marble and Oregon walnut interior panels adorning the Governor’s Ceremonial Suite. PMA was retained to guide the faithful restoration of this important Oregon icon.

Due to the third fire in the Oregon State Capitol’s history, the Governor’s Ceremonial Suite required complete restoration and renovation. PMA provided restoration documents for the repair and replacement of exterior marble, repair of interior walnut paneling, reinstallation of linoleum flooring, reintroduction of historic carpet, integration of preservation of historic materials, and the repair of plaster ceiling and walls. Additionally, PMA provided guidance to the conservationists repairing the WPA painting, which was also damaged. All restoration work was based on historic research and field analysis of existing materials.
