WoodWorks held the first CLT symposium in the US in 2013 and, over the last eight years, our team has helped hundreds of project teams realize successful mass timber buildings. This map shows buildings that are complete, under construction and in design across the US, and is updated quarterly.
To address critical gaps in knowledge and skills among contractors and installers, WoodWorks created the Mass Timber Construction Management Program as a pilot in 2019—and 2021 marks a major expansion. The program includes two distinct elements:
- Project management curriculum is offered by WoodWorks for individuals who estimate, procure and manage new commercial and multi-family construction projects in the US.
- Three Construction Management workshops will be hosted online in 2021:
- Speakers will include principals and key influencers from experienced mass timber construction companies, installers and designers. WoodWorks will augment their operational presentations with cost optimization and business case tools.
- Mass timber installer training is offered in partnership with various entities, and targets the crew leaders and installers who physically build structures on site. The first two programs have already delivered more than 2,500 training hours:
Two other training programs are in development and will be announced in the coming months. If your organization is interested in partnering with WoodWorks to provide mass timber installer training, contact our Construction Management Program Manager, .
COMING SOON: Mass Timber Construction Manual
Don’t miss the launch of our Mass Timber Construction Manual later this year. This practical resource will give you the information needed to plan, organize, manage and construct mass timber buildings safely and efficiently. Intended to be useful to a wide of construction professionals, it will include best practices related to bidding, planning, erection/assembly and finish considerations for contractors, tradespeople, installers and sub-contractors involved in mass timber projects. The manual can help bridge gaps in knowledge between your experience and the needs of mass timber projects. Sign up here to be notified when it’s released.
In the meantime, download our Mass Timber Construction Management paper for an overview of best practices and key resources such as construction management education, installer training opportunities and the WoodWorks Innovation Network.

Cost, Schedule and Labor
Cost estimating mass timber systems requires a holistic approach to compare costs and yield savings. A direct comparison of the price of a mass timber structural frame to the price of a steel/concrete frame will not provide an accurate overall project cost comparison. Mass timber has the potential to shave time off construction schedules, use less on-site labor and has other benefits that can impact the overall construction costs.
Costs for a mass timber system can be optimized with close coordination among members of the project team. WoodWorks’ Mass Timber Cost and Design Optimization Checklists guides coordination between designers and builders as they estimate and make cost-related decisions on mass timber projects. The pre-design section of the checklists has tips related to assembling a design/builder team, engaging the builder early in the design process, and contractual considerations, as well as mass timber’s potential benefits. The SD and DD Cost Optimization sections include items that builders should consider when estimating costs.
