Scope: Renovate exist boxing gym left vacant for years into a museum housing vintage automobiles. Demolish a failing portion of third floor walls to incorporate a new second story deck.
Challanges: Major demolition and shoring, confined worksite, sand/mortar stacked rocks completely unstable, unsafe previous modifications, unstable flooring not capable of holding equipment weight, mold and water damage throughout. Design build changes to work with existing building conditions uncovered.
Construction Notes: This seemingly easy project is one of the most difficult projects ever taken by our firm. The building shell was held together with sand and stacked leuder stone with no foundation. Occupied neighboring buildings shared walls, joist plates and roof anchorage with the failing structure. The rear of the building to be demolished had already broken away from the main structure and had to taken down by hand, small tools and anchored scaffold shoring to prevent collapse. The first floor space existing mezzaine was removed, floor joists replaced and a modified liquid cement agent was then infused into the exterior walls to stabilize the structure. Interior partitions and electrical was added to create the museum showroom. Finally, to create a outdoor living space for the second floor apartment, a deck was designed to finish out the building rear.
