Project Overview

JPMorgan Chase Bank hired Berglund Construction to restore the iconic façade and plaza at its tower in downtown Chicago. The work scope contained three primary components: granite repairs, sealant replacement and cleaning. 

Approach

The granite repairs included repairing cracked granite soffit and sill and column cladding panels on the building façade. Cracked granite pavers at the plaza and surrounding sidewalks were removed and replaced as well. 

The sealant replacement scope required removing and replacing the existing polyurethane sealant in the granite-to-granite and granite-to-metal joints on the exterior building façade. Berglund tuckpointers also removed and replaced the existing silicone sealant on the storefront windows below the third floor on the north, east and west elevations. Sealant in the south plaza was also removed and replaced. This included all of the existing polyurethane sealant in the granite-to-granite and granite-to-metal joints in all raised elements of the south plaza, including the walls, planters and clock towed. Additionally, Berglund removed and replaced all of the existing polyurethane sealant in the granite paver joints in the south plaza and all sidewalks surrounding the building, including the plaza stairs.

The cleaning scope required cleaning all components of the building façade, including the granite cladding, existing sealant and aluminum window components. All granite cladding — with the exception of the pavers on-grade — in the south plaza was cleaned, including planters, benches, walls and the clock tower.
