Symphony Hall

SGH investigated the condition of the masonry facade, roofing, and the granite steps at the Huntington Avenue entrance.

Working closely with the BSO, we developed a phased renovation plan to complete the work in four short sessions between their performance seasons. As the prime consultant, we designed repairs including the following:

• Repairing brick, limestone, and granite masonry
• Restoring or replacing doors and windows
• Replacing low-slope membrane and copper roofing
• Reinforcing masonry parapets with steel bracing
• Repairing portions of masonry piers supporting the granite steps
• Developing masonry cleaning procedures through a series of mockups

SGH led the effort to coordinate with the Massachusetts Historical Society and the Boston Landmark Commission to obtain approval for the work. Throughout construction, we collaborated with the contractor to resolve field conditions and provided construction administration services, including reviewing contractor submittals and observing ongoing construction to compare with the design intent.
