State Capitol renovations

BREATHING NEW LIFE INTO A BELOVED HISTORIC SEAT OF POWER

ADG Blatt worked as part of a design-build team to renovate the exterior of the historic Oklahoma State Capitol. Phase One included over $20 million worth of work starting with assessing and recording the conditions of all exterior limestone, brick and other materials. The team’s scope of work included presenting options and budgets for repairs and improvements that will allow the building to serve the state well for generations. Phase Two included $32 million for additional renovations of the stone battlements, all windows, doors, entrance stairs and ramps, light wells, sidewalks, plazas and terraces. In addition, an existing pedestrian tunnel leading from remote parking, under an arterial roadway into the basement of the Capitol will be upgraded with improved waterproofing, lighting and emergency systems.

The goal of the project was to return the building to a semblance of its former glory by using the original architecture while replacing key systems like weatherproofing, sealants, attachments and wall penetrations as needed. Improvements in engineering systems will be integrated into the architecture throughout and a separate team is working on building interiors.
