T3 Atlanta Office Building
Mass Timber at Scale.
The 7-storey T3 West Midtown project in Atlanta, at 205,000 sqft timber area, is one of the largest mass timber buildings in the US.
T3 West Midtown is the second T3 office building ("timber, transit, technology") for the developer Hines. For the second time, we had the privilege to work with the Hines team as the mass timber structural engineer and builder for the 6-storey timber superstructure. This building uses DLT panels over a Glulam frame with a steel brace frame lateral system. Team members included HPA / DLR Group, MKA and New South Construction.
The first T3 in Minneapolis was completed in 2016 and helped spark the mass timber “revolution” that is being experienced around North America, and demonstrated that, through efficient design and construction, timber can be used competitively in large scale commercial office spaces.
The gravity system is comprised of DLT (dowel-laminated timber) floor and roof panels over a Glulam post and beam substructure. The lateral system consists of perimeter and internal steel brace frames, which StructureCraft installed in sequence with the timber structure.
