IMTC 2025

2025 International Mass Timber Conference, March 25-27, in Portland, Oregon.

The International Mass Timber Conference (IMTC) is the world’s largest gathering focused exclusively on mass timber construction, design, and manufacturing. Held annually in Portland, Oregon, this premier event attracts thousands of industry leaders, architects, engineers, builders, investors, and policymakers from over 35 countries, creating a global forum for collaboration and knowledge-sharing. IMTC is dedicated to advancing the mass timber industry and promoting the sustainable use of wood in construction through innovation, regulatory insight, and sustainable forestry.

The conference covers key themes shaping the future of mass timber, including sustainable forestry practices, carbon reduction, regulatory advances, building design, and financial strategies. With mass timber's popularity growing as an eco-friendly building material, IMTC emphasizes its environmental benefits, focusing on carbon sequestration, efficient use of forest resources, and climate change mitigation. Sessions explore how sustainable forestry practices and certifications can meet the demand for timber while protecting ecosystems.

Highlights of IMTC

• The conference program is highly regarded for its educational depth and range. IMTC offers seminars and technical sessions, a pre-conference workshop produced by WoodWorks and offsite tours. These sessions cover a spectrum of topics, from fundamental mass timber principles and engineering to advanced fire safety and seismic resilience. In-depth case studies on notable mass timber projects provide real-world insights, showcasing how industry challenges have been met with innovative solutions.

• IMTC’s extensive networking opportunities are a core attraction, providing structured and informal settings for meaningful connections. From evening receptions to roundtable discussions to Women in Timber, attendees can connect with peers, industry pioneers, and potential collaborators. The exhibition hall is a bustling showcase of new products and services from mass timber manufacturers, material suppliers, and technology providers, offering attendees a firsthand look at the latest advancements.

• IMTC also serves as a platform for innovation and emerging technology. Each year, the event highlights new tools in digital design, robotics, and prefabrication that enhance efficiency and precision in mass timber construction. As mass timber becomes integral to sustainable development and urban density, these innovations represent valuable shifts toward faster, more resilient, and greener construction methods.

A key focus at IMTC is the evolving regulatory environment, including building codes and safety standards. Mass timber is now used in taller and larger structures, and sessions cover essential information on regulatory changes, safety codes, and testing advancements to ensure safe, compliant building practices. IMTC often hosts policymakers and code officials, providing a critical space for discussing code improvements that support mass timber’s growth and ensuring these structures meet the highest safety standards.

Diversity of attendees adds a unique international perspective, as IMTC brings together architects, contractors, developers, forestry professionals, and government officials from various backgrounds. This diversity enables cross-cultural exchange and collaboration, enriching discussions around regional practices, unique regulatory challenges, and innovative applications in mass timber.

In the days and weeks following the event, attendees gain access to post-conference resources, including recorded sessions, presentation materials, and continuing education credits. These resources extend the value of IMTC, allowing participants to revisit insights, share findings with colleagues, and further their learning.

The International Mass Timber Conference is a vital event that supports the mass timber industry's growth through collaboration, education, and the sharing of best practices. With each conference,
