BRUNSWICK, ME – Consigli Construction is managing construction of the Barry Mills Hall and the John and Lile Gibbons Center for Arctic Studies at Bowdoin College. The two buildings, which total 50,000 square feet, are being constructed with mass timber, including cross-laminated timber (CLT), as part of the college’s effort to be carbon neutral.

Mainebiz connected with the project team to learn more about the mass timber process.

While the foundation is concrete, there’s no structural steel and no concrete in the structure above ground, said Matthew Tonello, project executive for Consigli Construction, which managed construction of both buildings.

Tonello said the construction process was faster than if they’d used conventional materials. He demonstrated the construction process in a video that showed a side-by-side comparison of the construction timeline — mass timber vs. traditional concrete-and-steel construction.
