Solution
The damage to the building varied across the building. The parapets, stairs, and stoops were entirely deconstructed and rebuilt to set the elements in plumb and provide the appropriate structural repairs. Structural and stone repairs were provided with helical anchors and stitch repairs. Through the dedicated survey and full-time construction administration by the design team, this extensive exterior rehabilitation was able to salvage 94% of the existing stone. All of the work was able to be accomplished without disturbing the judicial process occurring within the building.
