What ACCO Delivered

This multi-tower structure was awarded as design-build to ACCO which includes a hotel, apartment building and ground-level retail and restaurant spaces. The hotel consists of a hot and chilled water 4-pipe fan coil system. The Hotel HVAC system is tied into a fully integrated Interel automated system that operates with lights, shades, TV and sleep settings that can be customized by the end user. The residential tower and common areas are served by a close-circuit condenser water system.

Renowned Canadian-American architect, Frank Gehry’s concept of this structure was to resemble the classic Jenga wood block game. The building design posed several challenges requiring ACCO’s Engineering, Construction and Systems Operations teams to work closely together to resolve.

Offsets and jogs of the building called for heavy MEP coordination of distribution floors and common areas for ductwork fire-rated separations used for smoke control and kitchen exhaust. Visual aesthetics and performance were important factors for the owner which ACCO achieved despite the many physical and technical challenges.
