Wyoming State Capitol Restoration
new stone with the exist- ing, using a variety of tech- niques to replicate surface texture. For highly deco- rative dutchmen, the pro- file of the stone was shop fabricated. However, areas of highly decorative orna- ment were roughly blocked out to be hand-carved and blended by stone masons in the field. Repairs to existing
stone also relied heavily on hand retooling and blending of the stone in the field to restore the historic appear- ance and provide improved slope to horizontal surfaces that historically collected water.
Approximately 3,160 cubic feet and 1,135 indi- vidual stone units were fab- ricated for the project.

Judges Comments:
This project was clearly the most impressive project they looked at this year in terms of complexity, execu- tion, challenges, and outcome. When you consider they did the restoration on a facility’s building that was open
to the public, they could have written a complete dissertation on the challenges that they must have faced. It’s a massive project that shows such a level of skill and craft in so many different areas, it had to win the award. One juror said: “To whomever did this work, I’m going to call them and just say, ‘Hats off’! This one is spectacular.”

The Wyoming State Capitol is a National Historic Landmark designed in the Renaissance Revival style by Davis W. Gibbs. The building was constructed in three build- ing campaigns completed in 1888, 1890, and 1917. The center portion of the build- ing was constructed first with the wings expanded during subsequent building campaigns.
Prior to the restoration, distress conditions included delamination of the sand- stone at the base of the building, a condition that was likely accelerated by a previously applied clear surface treatment. Severe delamination of the stone was also observed at cor- nices, column capitals, and other projecting horizontal
surfaces where the distress was primarily associated with water exposure and weathering.
The stone quarries from which stone for the original building were quarried in the 1880s were accessed for this project. This included reopening the quarry in Rawlins, Wyoming. New stone slabs were quarried and selected by the project team to match the existing stone on the building.
The stone dutchmen were shop fabricated with stan- dardized profiles typical to individual features of the building. However, the exact size and shape of the existing building profiles varied, as would be expected for a building constructed in many phases. Stone masons in the field were chal- lenged with blending the
