Your Digital Resource Guide for Mass Timber+ 2026
Oct 2, 2026
WoodWorks
WoodWorks is in Philadelphia October 6-8 co-hosting Mass Timber+ 2026. If you’re attending, stop by our booth to meet our team, ask technical questions, and pick up resources covering some of the issues project teams encounter most often.
Not at the conference—or prefer to keep things digital? We’ve gathered the same resources available at our booth here. Explore guidance on mass timber design, code, cost, and more, all available at no cost from WoodWorks.
Solution Papers: Breaking Down Design & Construction Topics
Mass Timber Cost and Design Optimization Checklists
The design optimization checklists are intended for building designers, but many of the topics should also be discussed with the fabricators and builders. The cost optimization checklists will help guide coordination between designers and builders as they estimate and make cost-related decisions on a mass timber project.
How to Successfully Cost Manage a Mass Timber Project
Covers cost estimating considerations for general contractors with an emphasis on minimizing whole project costs and maximizing the value of mass timber projects
Designing with Wood Under the IBC: Construction Types, Building Size, and Fire Resistance
Explores the interconnection between allowable building size, construction type, occupancy, FRRs, and other fire and life safety requirements in the design of wood buildings
Taking the Guesswork out of Mixed-Use Building Requirements
Design strategies and fire separation details for light-frame wood buildings
Overview of mass timber products and their applications, where to source mass timber for U.S. projects, and key resources for developers, building designers, and construction professionals.
Tall Wood Buildings in the 2021 IBC – Up to 18 Stories of Mass Timber
The 2021 IBC includes three new construction types—Type IV-A, IV-B and IV-C—allowing the use of mass timber or noncombustible materials. This paper summarizes the background to these proposals, technical research that supported their adoption, and resulting changes to the IBC and product-specific standards.
