Minnesota State Capitol Interior Masonry project

Minnesota State Capitol interior restoration project

Minnesota State Capitol
– Interior Renovation

St. Paul, MN

AMR spent five years as part of the project team preserving the Minnesota State Capitol. The State Capitol is Minnesota’s most recognized building that was designed and built in the early 1900s by the architect Cass Gilbert.

The work AMR completed was removing all existing fasteners and unused anchors, patching all existing holes, and replacing missing tiles in existing Guastavino tile ceiling to match color and pattern of existing adjacent material. As well, the repair and alteration of existing stone surfaces: Kasota limestone, marble, terrazzo floors; resetting cracked stone, replacing missing pieces, replacing bad patches, grouting stone joints and repairing surface damage to stone face.

The overall project took over one year, with over 1,200 repairs of masonry on all the interior masonry in various locations throughout the complex.
