“Constructing these buildings during a global pandemic involved extraordinary supply chain and scheduling challenges” with the pre-cut mass timber shipped in more than 30 containers from Europe and “delivered sequentially for in-time assembly,” says Matthew Orlando, Bowdoin senior vice president for finance and administration.

To protect sensitive artifacts housed in the Peary MacMillan Arctic Museum, “our team engineered an efficient all-electric system while maintaining critical temperature and humidity control for collections,” says Rebecca Celis, principal and arts, community and education sector leader at Boston-based architecture firm HGA.

The cross-laminated timber floors and roofs are supported by glulam timber beams and columns and roof glulams secured with steel ties, says Lauren Piephho, structural engineer at the company.

“Bowdoin is committed to eliminating on-campus fossil-fuel emissions by 2042 through decarbonization strategies and the adoption of renewable energy sources,” Orlando says. The team chose 100% electric energy for Mills Hall and the Gibbons Center to offset the electric load with both new and existing solar contracts, making these buildings the first net-zero facilities on campus, he adds.
