Based on a master plan by Bruner/Cott & Associates to reimagine Josep Lluis Sert’s 1960s Boston University School of Law complex for modern use, Skanska USA Building Inc. completed construction of the new Sumner M. Redstone Building and the full restoration of the existing 18-story tower for Boston University’s School of Law. The project is considered a large-scale restoration due to the existing tower, originally built in 1962.
The new Redstone Building houses most of the new classrooms and community areas, which is 92,000 square feet of space. The tower renovation was 18 stories of about 96,000 square feet, but also entailed a full restoration of the exterior façade. It's now the home of the entire faculty, two large classrooms, and several practice courtrooms.
The exterior restoration included replacing 1,000 windows, installing 20,000 linear feet of sealant, and restoring the existing cast-in-place concrete façade, which included more than 2,800 individual patches.
Aesthetics was important to the owner, which required the contractor to achieve the perfect color match for the final mix designs. “There were over 40 different mock-up samples performed for the mix design and coloration approval by the design team. Ultimately, two mix designs were approved and implemented,” says Darrin Ball, senior project manager of Skanska.
The restoration aspect of the project faced difficulties with temperature restrictions, lack of qualified people to perform the restoration work, and logistics due to the existing building being occupied for half of the project’s duration. The entire project started in late 2012 and was completed in July 2015. Both phases were on time and within budget.
