This program introduces essential engineered wood framing products and strategic insights for successful mass timber design. The first half of the session will cover materials such as glulam, structural composite lumber (SCL), and cross-laminated timber (CLT), exploring their composition, applications, industry standards, and best practices. Participants will also learn fundamental wood beam principles, including notching, drilling, and connection concepts, to better understand product allowances. 

The latter half of the session will focus on critical early design decisions that impact cost and feasibility. Many teams miss opportunities by applying traditional building practices instead of optimizing for mass timber. This session will cover construction types, fire ratings, column grids, beam and panel spans, acoustics, and MEP integration. Using case studies, it will illustrate how early choices shape project outcomes and maximize efficiency.

Learning Objectives

1. Recognize common mass timber framing products, including their composition, characteristics, and applicable standards for SCL, CLT, and glulam.

2. Explain best practices for specifying glulam beams, including connections and allowable modifications such as checking, notching, drilling, and hole cutting. 

3. Identify permitted mass timber construction types in the International Building Code and their impact on fire-resistance ratings, structural spans, and grid layouts.

4. Explore code-compliant solutions for acoustics, frame connections, and MEP integration, considering their effects on cost, aesthetics, occupant comfort, and future adaptability.
