The Challenge

Buildings are enormous generators of both operational and embodied carbon, accounting for approximately 40% of global greenhouse gas emissions. Unlike operational carbon emissions, such as heating and cooling, that can be upgraded over time, embodied carbon emissions from material extraction, transportation, manufacturing, and construction are locked in the moment a building is finished. With building floor area projected to double globally by 2060, addressing embodied carbon emissions is increasingly urgent.

Common structural materials like concrete and steel are especially carbon intensive and financially volatile. Mass timber is a material that offers a regional, renewable, carbon storing alternative. Large engineered wood panels, columns, and beams sequester carbon for the life of the building. Mass timber is consistently faster to build with, cost-predictable, healthier for occupants, and provides much needed partnership to forests looking to adapt to quickly changing business and climate environments.

Despite Mass Timber's innumerable benefits, however, as a relatively new building material, project teams still face uncertainty around key issues of cost, procurement, and design coordination.

About MASS Timber Assembly

MASS Timber Assembly is a 12-month cohort program for Massachusetts building project teams pursuing mass timber construction. Up to eight teams will be selected to receive grant funding, hands-on technical assistance, facilitated peer-to-peer learning, and workshop sessions with industry experts; all committed to sharing their experience about how to best advance individual projects and mass timber adoption more broadly.

MASS Timber Assembly is designed to:

  • Advance the design and construction of mass timber projects in Massachusetts
  • Build the capacity of Massachusetts-based project teams to design and construct mass timber buildings
  • Generate knowledge to expand the market for mass timber in Massachusetts

Participants will receive:

  • $40,000 in grant funding per project team
  • A structured technical analysis of the project’s cost, construction schedule, and carbon impacts, developed collaboratively with the project team
  • Dedicated 1:1 technical assistance from mass timber and embodied carbon experts
  • Access to key decision makers in the mass timber supply ecosystem, including hands-on workshops and industry roundtables
  • Peer-to-peer learning with seven other project teams navigating similar challenges
  • In-person program sessions, including: a kickoff event, technical training from WoodWorks, a dedicated construction-management session, a mid-program industry roundtable, and a final showcase
  • Shared team workspace and cohort communications tools
  • A published case study in the MASS Timber Assembly project collection

Who's Eligible

MASS Timber Assembly is open to any active project team in Massachusetts committed to mass timber construction.

Applicant teams must include:

  • A project owner or developer
  • An architect
  • A general contractor

Structural engineers are strongly encouraged as part of the project team.

Projects may be at any phase, from early design through pre-construction. Hybrid mass timber projects and existing building renovations and additions are welcome. Both first-time and experienced mass timber teams are encouraged to apply. All building types and most building sizes are eligible. Housing is a particular priority given Massachusetts’s current housing needs; housing projects must include six or more units.

Frequently Asked Questions

Can a team apply with more than one project?

Yes, a team may submit multiple applications for different projects. Each application will be evaluated independently.

What if my project is a renovation/addition to an existing housing project, but the additional units are less than 6?

Write to us with your specific scenario and we can discuss!

My housing project is less than 6 units, do you have any resources for me?

Yes! Please write to us and we can connect with people doing this work.

FAQs continue...

What is the time commitment for participating teams?

This is a 12-month program. There will be mandatory attendance for select in-person sessions (including the Kickoff, Mid-point Roundtable, final Showcase, and other sessions determined by the group). In-person attendance is encouraged at all non-mandatory sessions, but virtual attendance will be accommodated knowing teams may be distributed across the Commonwealth. Teams are expected to participate in virtual office hours, attend one-on-one support sessions with WoodWorks and other outside advisors, and actively engage with the rest of the cohort in peer-to-peer sharing and learning.

What wood sourcing or timber transparency requirements are there?

There are no specific timber sourcing requirements, however, the program will emphasize the role of sourcing and transparency as essential elements in mass timber's growth, and will provide technical assistance to teams pursuing intentional sourcing requirements. At end-of-program reporting, teams will be asked to share basic information about the wood used in their project including manufacturer, panel specification, species, and Environmental Product Declarations. Additional sourcing and chain of custody information will be encouraged when available.

Will projects be required to complete a whole-building life cycle assessment (WBLCA)?

Yes. As part of the Mass Timber System Analysis, each team will complete a cradle-to-gate whole-building LCA for their project. The consulting team will provide technical assistance on LCA methodology and help teams access appropriate tools and resources. The program will develop benchmarks that draw on existing data to contextualize individual project results and estimate embodied carbon reductions.

When does the program begin?

Program selection will be announced in September 2026, and the program itself will kick off in September or October 2026.

Who delivers the program?

MASS Timber Assembly is funded by MassCEC and delivered by BC Productions (program strategy and stakeholder engagement), Cambium (program management, technical assistance, and data collection), and WoodWorks (education, technical training, and project support).

Our project team does not yet have a general contractor under contract. Can we still apply?

Yes. Projects in early design (and public projects subject to procurement requirements) may not have a general contractor on board by the application deadline, and we don't want that to keep strong teams from applying.

Submit the Joint Commitment Letter signed by the owner/developer and architect and leave the general contractor signature block blank. In its place, attach a short, signed statement from the owner/developer committing that the general contractor or construction manager, once engaged, will participate in MASS Timber Assembly. No substitute signatory is required.

We are not setting a deadline for naming a general contractor. Applications without one will be evaluated under the same published criteria as all others, including whether the team is positioned to engage fully in the program.

We're a technology provider or industry partner interested in supporting the MASS Timber Assembly cohort. How can we get involved?

Thank you for your interest in the MASS Timber Assembly program. Billy Craig, WoodWorks, and Cambium make up the core technical assistance team for this cohort, and that scope is set as part of the program's agreement with MassCEC.

To keep the program fair to every applicant and cohort team, we don't broker preferential introductions or match specific vendors to specific projects. What we can do is surface useful tools, materials, and approaches as general education for the whole cohort, so teams can see what's available and decide for themselves what fits their project. Any team is always free to engage an outside provider directly on their own. The program is also still in active planning, and the exact mix of sessions and topics will be shaped by what the cohort teams tell us they need once we're underway. If there's a natural fit, we're glad to keep your information on file and consider it as that picture comes together. If you'd like to stay in the loop, feel free to check back on the program page for updates.
