Challenge:
Removal of existing EPDM, ballasted roof, and wet insulation with consideration for 21 exhaust fan units used in ongoing experiments as well as curtain wall repairs.
Solution:
CBI designed new, custom flashing details at parapet walls and coordinated phased refurbishing of the exhaust fan units. New universal electrical mounts with new wiring and boxes installed at each fan. The deteriorated parapet cap was replaced with a new precast concrete cap to match existing; then coated with opaque sealer. Exposed aggregate architectural finish exterior building skin was repaired with concrete spall repair techniques using custom concrete mix and aggregate from location of original precast supplier. Epoxy injection was used at exposed aggregate finish and extensive caulking.
