SGH assisted the architect in developing a design to maintain the appearance of the iconic steel and glass window wall, while addressing deterioration and performance issues. Highlights of our design include the following:

• Removing the original seeded glass, laminating it to improve safety and breakage resistance, and reinstalling it in new panels

• Exchanging previously replaced glass, which did not match the original, with new laminated seeded glass from Germany

• Replacing the corroded and buckled steel frame with a custom, painted stainless steel frame matching original profiles and designed to accommodate thermal movement, preventing reoccurrence of the buckling issue

SGH designed repairs for the chapel’s failed and leaking concrete moat, including reconstructing the structural slab-on-grade, installing a waterproof liner, and constructing a topping slab to recreate the original configuration and texture.

Our design to restore the skylight illuminating the altar and iconic Bertoia sculpture hanging from the oculus included replacing broken glass, refurbishing the frame, installing new glazing and flashing, and designing a protection screen to protect the skylight from ice and snow falling from the bell tower.

SGH also assisted with designing a replacement roofing system to address persistent leakage. To install base flashing details beneath the legs of the bell tower sculpture by Theodore Roszak, the contractor removed and reset the bell tower in a single day.
