Project Scope: Restoration Project
The Minnesota State Capitol Building, designed by prolific architect Cass Gilbert, is an iconic building for all Minnesotans, and especially for the St. Paul skyline. The Capitol building is currently undergoing its first major building preservation campaign since its construction in 1905. The four-year construction project is estimated at $310 million and includes multiple design and construction team members. Critical issues included failing and deteriorating exterior components, life safety concerns, antiquated building systems, and inefficient public spaces.
PVN worked with HGA Architects and Engineers, the project architect, to provide construction documents for the repair of the roof of the capitol building, including on-site investigation, material condition assessment of historic roofing components, preservation design expertise, and production of construction documents for the roof repair. The capitol project was based on over 30 years of predesign and planning efforts. PVN reviewed existing roof reports and schematic designs before beginning site investigations of current conditions. Following the initial on-site survey, PVN collaborated with HGA to develop design strategy and details, including areas that needed additional investigation to understand existing conditions. The condition of roofing elements, integration of drainage, and historic copper material conditions required team collaboration and specialized solutions. PVN also produced roof repair construction documents for integration into the overall construction package.
