Water Infiltration Investigation and Exterior Rehabilitation
Stony Brook, New York
Designed by New York architectural firm Kelly
& Gruzen, now IBI Group – Gruzen Samton,
and completed in 1967, the Earth and Space
Sciences Building houses Stony Brook
Universi-ty’s Department of Geosciences The concrete
facade typifies the béton brut architecture of the
period, with a Modernist aesthetic
characteris-tic of Kelly & Gruzen’s midcentury work
How-ever, beset by water infiltration over a number
of years, the building had achieved notoriety
among students, faculty, and staff for leaks that
frequently disrupted teaching, research, and
ad-ministrative activities
The New York State University Construction Fund (SUCF) retained Hoffmann Architects to diag-nose the cause of recurrent water intrusion and to develop a rehabilitation solution Belying a com-plex system of eleven roof areas, some of which are accessible from the main level, the Earth and Space Sciences Building is a utilitarian four-story structure with a penthouse, clad in a combination
of cast-in-place concrete and precast concrete panels
Developing a design solution for the Brutalist building necessitated invasive probes and environmen-tal testing, in order to confirm the composition and condition of building envelope elements To this end, Hoffmann Architects coordinated the services of several sub-consultants for sample collection, roof probes, hazardous material testing, ventilation system evaluation, and air and water infiltration testing Our architects also conducted an interior finish damage survey and an evaluation of the waterproofing needs of the rooftop astronomy observatory
To resolve water infiltration conditions, Hoffmann Architects recommended roof replacements at ten of the eleven roof areas, along with concrete repair and coating, sealant system replacement, and replacement of compromised windows The project team, in consultation with the university’s As-tronomy Department, also recommended replacement of the existing observatory, so as to protect the recently acquired telescope from water damage Hazardous material abatement (for lead, as-bestos, and polychlorinated biphenyls,
or PCBs), and replacement of damaged
doors, hatches, and skylights were also
included in the recommended scope
of repairs
Hoffmann Architects developed
Con-tract Documents, assisted with
con-tractor bidding, and provided
construc-tion administraconstruc-tion services for the
building envelope rehabilitation project
