MIT wanted to improve the building’s performance, code compliance, durability, and functionality, while respecting and preserving the historic significance and integrity of the Saarinen design.
SGH developed a structural and building enclosure rehabilitation design for the curtain wall to improve life safety, durability, and energy efficiency, while being true to the original design. We designed replacement curtain wall framing members to support heavier glass lites while maintaining the original profiles and without compromising sight lines. We achieved this by supporting the new curtain wall and heavier glass directly on the building foundation and reducing gravity loads on the existing interior structural steel framing, so it only needed to support wind loads. Our rehabilitation plan also included retaining and restoring the original interior steel members originally supporting the curtain wall framing, replacing curtain wall glazing with heat-strengthened laminated glass with a low-emissivity coating to improve safety and thermal performance, and repairing the curved concrete edge beams of the thin shell concrete roof.
SGH also consulted on roofing and waterproofing repairs for the auditorium. We designed plaza waterproofing repairs to protect below-grade spaces, and collaborated with the contractor to develop repairs for the curved copper roofing, perimeter gutters, and flat-seam copper at the peak of the roof.
