Constructed in 1962, the 12-story commercial office building consists of a penthouse roof, main roof frame and a lower roof located at the tenth floor level. The combined roof plate is approximately 19,000 sf. The original roofing membrane over the penthouse structure was overlaid with a loose laid EPDM rubber membrane. The main roof and tenth floor roof coverings were replaced in 1986 with a liquid applied membrane system in an IRMA configuration.
The first phase of the project consisted of the removal of the existing roofing system over the penthouse roof and replacement with a 20 year two-ply SBS system. The project scope also included installation of safety tie-off anchors for the attachment of lifelines and safety-lines used by window washers.
Additional consulting services provided included: an existing condition evaluation report, preparation of budget estimates for the phased roof covering replacement, preparation of construction documents, assistance in the bidding, negotiation and contract award process, and construction administration services during execution of the work.
