Sound and Vibration in Mass Timber Buildings: A Practical Guide

Course Overview

Following an introductory overview of building acoustics, the presenter will explore both airborne and impact sound transmission in mass timber buildings. While direct sound transmission (i.e., through floor/ceiling assemblies) has been thoroughly tested, indirect sound transmission (i.e., around wall or floor/ceiling assemblies) remains more of a challenge. To address this, the presenter will share findings from recent R&D initiatives aimed at helping maximize exposed mass timber while still adhering to code requirements.  

This webinar will also examine the sound absorptive properties of mass timber, which play a critical role in environments such as schools, offices, and event spaces. Finally, we’ll conclude with specific design strategies to help prevent late-stage acoustical issues, especially when projects have progressed to a point where certain solutions are no longer feasible. 

Learning Objectives

  1. Gain familiarity with basic acoustic terminology and principles.
  2. Understand how sound and vibration can transmit directly and indirectly through the mass timber structure.
  3. Discover approaches to addressing sound and vibration transmission through continuous mass timber (CLT) panels.
  4. Gain an appreciation of various design considerations affecting the control of noise in mass timber buildings.

Dowel Laminated Timber A new mass timber product in North America

Course Overview

Dowel‐laminated timber is a next generation mass timber product commonly used in Europe, where it is also known as brettstapel. Panels are made from softwood lumber boards stacked like the boards of NLT, friction‐fit together with hardwood beech dowels instead of nails. DLT is the only mass timber product which is 100 per cent wood – it involves no glue or nails. Unique to DLT as a mass timber product, acoustic profiles can be integrated directly into the bottom surface of a panel. DLT panels processed using CNC machinery create a high tolerance panel which can also contain pre‐integrated electrical conduit and other service runs. StructureCraft will be the first manufacturer of DLT in North America, with a new automated manufacturing line and plant beginning production in 2017. This presentation will discuss how DLT differs from other mass timber products in its use and specification. Topics will include potential applications, introduction to the design and construction process and costs.

Learning Objectives

  1. What is Dowel Laminated Timber?
  2. Potential applications of DLT.
  3. Introduction to design and construction detailing.
  4. Product availability and cost.

CLT classrooms: A pilot project in Washington State

Course Overview

A pilot project in Washington State tests the use of CLT to design and construct three modular classroom buildings in Western Washington. Funded by the Washington State Legislature, the project investigated the viability of CLT as a means to build quality K‐3 classrooms to accommodate increased population and new WA State education laws. By using CLT, the project team designed a building that could be deployed on almost any existing school site and be built over a summer break without impacting ongoing operations. Compared to traditional portable classrooms, the CLT classroom buildings are longer lasting, more functional, and aesthetically superior.

Learning Objectives

  1. Building a broad‐based CLT coalition and the unified strategies for securing legislative state support and funding ($5.5 mil USD).
  2. Architectural design and detailing strategies used to create an innovative learning environment by using CLT.
  3. Project scheduling, costing, construction and lessons learned through building the modern classrooms at these three schools.
  4. Utilizing a design‐build delivery method.
