At time of permit, Framework was the tallest all-wood building in North America at 12 stories

"Framework was the first wood high-rise design in the US to receive approval for construction. The project sought to be a catalyst that connects sustainable urban development to rural economic growth regionally and nationally. Framework was supported by a 1.5 million dollar award from the US Tall Wood Building Prize Competition to offset the costs of testing and peer review necessary to pursue a performance-based project beyond what is permitted in current building codes.

The mixed-use design combines retail and public exhibition on the ground floor, with five levels of office, and 60 units of affordable housing. Framework’s commercial tenants were to be B corporations (businesses certified to meet rigorous standards of social and environmental performance, accountability, and transparency). The housing component of the project was designed to accommodate residents earning less than 60 percent of the Area Median Income (AMI)." - LEVER Architecture

In what was to be a world first, the structure uses a post-tensioned rocking wall Cross-laminated timber (CLT) core as the lateral stability seismic system. Extensive testing is being conducted to prove this system. CLT panels up to 40' long form the floor system, resting on Glulam beams and columns.

Our team provided delegated structural engineering services, including structural analysis & design, 3D modelling, and structural/fire testing services for the timber structure, working in collaboration with KPFF.

The project is Design Complete.
