We've been here since the beginning

Our experts were involved with the development and early adoption of mass timber criteria in U.S. building code regulations years before the International Code Council (ICC) adopted mass timber provisions in 2015. We serve on mass timber university studio panels, consult with wood laboratories and provide education to clients and industry associations to support ever-developing, modern uses for these green building products.


Mass timber is still developing into its full potential for resiliency and design aesthetics. Our team supports the research and discovery of undocumented uses and creative applications for these materials.

Our experts navigate requirements governing tall wood buildings as well as develop alternate methods and materials for applications, such as increasing the exposed surface area of mass timber panels.

We support designers in selecting and defending joint and edge protection details, product analysis, assembly analysis, char ratings, and other calculations for scientific validation that will prove performance and compliance.


In addition to our mass timber project and market development experience, our experts have jurisdiction experience across the United States and beyond.

Our compliance alternates and negotiations have resulted in mass timber being used for high-rise buildings, health care facilities, residential towers, education and business campuses, and many other civic and private developments.

We regularly interface with city officials and client stakeholders to address questions and develop strategies that meet the intent of code and local adoption while pushing forward innovation and modern design through custom research and analysis.

For each project we undertake, our goal is to understand the form and function of each structure, desired aesthetics, and code-compliance challenges so we can develop a scientific approach to address fire and life safety needs.

We research and develop alternate means, methods, variances, interpretations, and research-backed engineering judgments to support our clients’ design goals.

Our building code and fire experts are dedicated to supporting wood products and other sustainable building materials and methods on a project-by-project basis and in wider adoptions into current and future building code standards.


From master planning and construction documents to all the design team and AHJ meetings in between, we work with clients and stakeholders to achieve applicable fire and life safety design requirements.

Our team of engineers, code experts, and analysts add value to a mass timber project by identifying the best construction type, proving performance, and providing analysis to allow combustible material use in a non-combustible structure. We also develop and research unprecedented assembly systems.

We collaborate with design teams through integrated design processes or at any design and construction phase to
