28th Annual Reconstruction Awards: Modern day reconstruction plays out

In the fall of 2008, Boston’s Modern Theatre looked anything but modern. Listed on the National Register of Historic Places, the landmark structure, located in the city’s Downtown Crossing area, was on the brink of collapse when Suffolk University invested $30 million to reconstruct it.

Suffolk University purchased the building from the city of Boston in 2008 in order to enable it to meet the growing needs of its theater program and provide a new student residence hall, according to Gordon B. King, the university’s senior director of facilities planning and management. “The reuse of the property fit well into Suffolk’s master plan, which called for the addition of new housing for 197 students,” he said.

HISTORICAL THEATER EXPERIENCES BOOM, THEN SUFFERS NEGLECT
Designed in 1876 by architect Levi Newcomb, the building originally housed two cast iron storefronts and a carpet storage warehouse. In 1913, the building underwent its first reconstruction. Architect Clarence Blackall was hired to convert the building into a theater for showing silent motion pictures. Blackall incorporated a marble addition into the main façade and inserted a narrow 800-seat auditorium into the basement and first three stories of the structure.

By the late 1920s, the theater was a trailblazer for “talkie” films. But it didn’t take long before the Modern was struggling to compete with larger, more up-to-date theaters throughout Boston. The owners struggled to fill the seats, but the long, slow decline of the theater was set in motion.

The 1970s saw a brief effort to rehabilitate the theater, but that failed and the structure was sold in the early 1980s. It sat largely untouched, rapidly deteriorating for more than 20 years until Suffolk University acquired it four years ago.

DEVELOPING A TRULY ‘MODERN THEATRE’ FROM THE GROUND UP
When Suffolk University acquired the building, the interior was in such disrepair it was no more than a decaying shell—only the façade could be saved. A few original items were preserved, including a 26-foot-wide painted screen tapestry from the early 1900s Modern Theatre, along with some paneling, wall coverings, and cornices.

“The existing building was in very poor structural condition and was condemned by the city,” says Adam McCarthy, PE, a principal with McNamara/Salvia Inc., Boston. However, the Building Team was committed to designing a new theater that would invoke contemporary standards of comfort and technology, while echoing the form and feeling of the building’s past. In addition, a 10-story residence hall built atop the theater would serve as Suffolk University’s newest dormitory.

STRUCTURAL PROBLEMS BETWEEN RESIDENCE HALL AND FAÇADE
Because the original auditorium was very deep but extremely narrow, reconstruction of the Modern Theatre posed difficult structural design problems.

“We had many challenges with reincorporating the historic façade back in the project, with a major one being how the building movements from the new residential building could be accommodated by or isolated from the historic façade,” says McCarthy. “This led to a great deal of structural modeling and detailing to achieve the acquired goals.”

The narrow building design would make the tall, thin residential hall portion of the structure act like a sail in the wind. The structural engineers had to deal with the complexities associated with the softening of the transfer members created in the lateral force resisting system.

Transfer members carry the load from the residential floors above and spread it over the top of the performance space. With a mostly moment-frame reinforced steel structure, the tower deflects significantly more than the historic stone and masonry façade is able to accommodate.

“This required a carefully detailed and exactingly constructed set of slotted structural connections and expansion joints, as the stone façade still relies on the tower for lateral bracing in its weak axis,” says Adrian LeBuffe, senior associate and project architect with CBT Architects, Boston.

The Building Team next turned their attention to ensuring the original façade would fit seamlessly on the new structure.

Prior to tearing down the original structure, the Building Team spent two months studying, planning, and preparing for the removal of the façade and the restoration process.

As the Building Team deconstructed the white Vermont marble and sandstone exterior, each piece was individually cleaned and catalogued prior to reassembly. Total laser scanning was utilized to obtain exact profiles of each stone, and BIM was used to load the data into a 3D model. This enabled the Building Team to identify dimensional problems with the façade and eliminate conflicts due to the redesign of the new structure, including the façade’s interaction with structural steel. This allowed for the arrangement of special off-site fabrication to avoid any conflicts. As a result, masons were able to install the façade smoothly and efficiently.

“Despite the difficulty of façade deconstruction on a very tight site, a variety of difficult stone restoration issues, and the demands of façade reconstruction to modern code and programmatic requirements, the project went quite smoothly,” says LeBuffe.

The reconstruction of the Modern Theatre resulted in a unique venue in Boston. The Building Team revived a city landmark and included design elements that modernized the distinctive features of the original 1900s theater while preserving the building’s historic façade.

“The city’s vision for restoration and historic preservation in the Lower Washington Street area and [the Building Team’s] vision for this project were one and the same,” said King. “The restoration of the Modern Theatre—one of the area’s three landmark theatres, along with surrounding residential and commercial buildings, has brought beauty, vibrancy, and economic vitality back to the neighborhood.” +
