Mercer Mass Timber and CLT Toolbox Launch Structural Design Software Partnership

On Thursday, Mercer Mass Timber (MMT), a leading manufacturer of sustainable timber building materials and a subsidiary of Mercer International, announced a strategic partnership with CLT Toolbox, a structural design software platform built specifically for mass timber buildings.

The collaboration marks a major step toward making mass timber a mainstream construction material by connecting advanced digital workflows with real-world manufacturing capabilities. By embedding product-specific, code-compliant design tools into a digital platform accessible to structural engineers worldwide, the partnership removes long-standing barriers that have historically slowed the adoption of mass timber as a mainstream building solution.

This is one of the first integrations of its kind in North America and signals a broader shift toward digitized, scalable mass timber construction. By simplifying design, manufacturing, and installation, MMT and CLT Toolbox are using advanced technology to remove complexity from workflows and accelerate the transition to low-carbon building systems.

This integration provides benefits throughout the building lifecycle for engineers, architects, developers, and the industry at large.

Commenting on the collaboration, Dr. Ricardo Brites, PhD, Director of Engineering & VDC at Mercer Mass Timber, said:

“Our collaboration with CLT Toolbox is about facilitating digital design in the realities of mass timber fabrication. It’s a smart, integrated, and accessible approach—and exactly the kind of alignment the industry needs.”
