CBT reconstructed Harvard University’s Memorial Hall tower spire nearly 50 years after it was destroyed by fire. Originally designed by two Harvard graduates, architects Henry Van Brunt and William Robert Ware, the 70-foot spire was built in 1874 as part of Memorial Hall, commemorating Harvard men of the Union Army who died in the Civil War. The cathedral-like building also houses dining services and Sanders Hall, a small performance theater. Before the spire was destroyed in 1956, it had been modified twice. Since all three spires were designed by the same architect, CBT conducted extensive research to assist the University in selecting the most appropriate version for reconstruction. CBT recommended restoration of the second design, which best captured the building’s architectural style and sense of history. CBT worked with Harvard and consultants to determine the original construction details, materials, and methods, and developed solutions to facilitate the construction process. The team performed in-depth analysis of slate colors and patterns and thoroughly investigated sources and craftsmen for the complex copper work and other materials.
