Ryan Biggs | Clark Davis provided professional engineering services to assess the existing condition of the Empire State Plaza Grand Stair in Albany, New York. We also assisted in sequencing the work to prevent excessive rebound and damage during removal and reconstruction activities, and analyzed the necessary stone support and anchorage.

The project involved the removal of the granite stairs and marble parapets and the construction of a new concrete sub-slab with fully integrated drainage mat. The granite stairs and benches are anchored over pedestals, utilizing a unique rain screen approach to promote effective drainage, address existing moisture-related problems, and prolong the lifespan of the structure and masonry.

The top flight of reconstructed granite stair treads and benches was set at the Grand Stair. The work represents a significant milestone for the project, which involves the complete reconstruction of the waterproofing system of the monumental stair structure, which spans over Madison Avenue and connects the terrace of the New York State Museum with the Plaza to the north.
