In 2006, SGH performed a comprehensive facade condition assessment, identified systematic failures, and developed immediate and phased repair recommendations for MIT. The University then retained SGH for multiple facade restoration projects. SGH completed hands-on investigations to obtain information critical for designing comprehensive repairs.
We incorporated contemporary technologies into our designs to enhance enclosure performance while remaining sensitive to the original aesthetics. Highlights of our design include the following:
- Redesign of the parapet wall system to convert the existing damaged mass masonry walls to modern cavity wall construction, incorporating expansion joints and waterproofing and flashings to direct water to the exterior, as well as seismic upgrades to meet Massachusetts Building Code requirements
- Full removal and replacement of the original steel-framed, single-glazed windows with contemporary customized aluminum windows with insulated glass units and thermal breaks for improved thermal performance
- Pan flashings beneath all windows, utilizing cutting-edge fluid-applied waterproofing technology as flashing in select areas to eliminate the need for metal drip edges that would have altered building aesthetics
- Repointing all masonry, rebuilding damaged masonry, replacement of corroded steel lintels with galvanized steel lintels protected by fully soldered metal flashings, and restoration of cast iron spandrel covers and anchors
