International Code Council Building Safety Month

Awareness Activities Hosted by American Wood Council


During the month of May, the American Wood Council (AWC) will be celebrating the International Code Council's (ICC) Building Safety Month to raise awareness and help individuals, families and businesses understand what it takes to create safe and sustainable structures. The campaign reinforces the need for adoption of modern, regularly-updated building codes, a strong and efficient system of code enforcement and a well-trained, professional workforce to maintain the system.


Week 1 (May 1-5): Preparing for Disasters: Build Strong, Build Smart
To kick off Building Safety Month, AWC will be covering how to prepare for disasters by building smart and strong. AWC will highlight their reference standards which are state-of-the-art, ensuring wood construction meets the latest recommendations on design loads and gives designers the tools they need. In addition, AWC will be sharing information about our code-referenced consensus standards via social media and our website. You can follow the conversation on Twitter via #BuildingSafety365, #BuildingSafetyMonth, #BuildWithWood, #WoodBuildsOurWorld.
Week 2 (May 6-12): Ensuring a Safer Future Through Training and Education
As an ICC Preferred Provider, AWC will be sharing information about our educational materials and courses for wood design and construction best practices as well as construction fire safety practices during week two. You can follow the conversation on Twitter as well as LinkedIn via #BuildingSafety365, #BuildingSafetyMonth, #BuildWithWood, #WoodBuildsOurWorld.
Week 5 (May 27-31): Innovations in Building Safety
AWC will be highlighting the role of the ICC code development process and how it successfully paved the way for the acceptance of tall mass timber buildings. The TMT (Tall Mass Timber) code changes are a good example of how the ICC process can work to allow for the introduction of new technologies and building systems. AWC will be sharing content and informational resources, including an infographic and tall wood toolkit on how to effectively navigate the new code changes.

Acoustical Values Added to AWC’s DCA 3

Apr 02, 2020

LEESBURG, VA. – The American Wood Council (AWC) has released an updated version of Design for Code Acceptance (DCA) 3 – Fire-resistance Rated Wood-Frame Wall and Floor/Ceiling Assemblies, which now includes sound transmission characteristics of floor/ceiling assemblies. A free pdf version of DCA 3 can be found on the AWC website at

While DCA 3 primarily focuses on the fire-resistance ratings of tested wall and floor/ceiling assemblies, the document also provides useful information regarding detailing of intersections of fire-resistance rated assemblies and sound transmission characteristics of the floor/ceiling assemblies described in DCA 3.

Model building codes stipulate minimum required Sound Transmission Class (STC) and Impact Insulation Class (IIC) values for floor/ceiling assemblies. The latest revisions to DCA 3 include the addition of STC and IIC ratings for multiple variations of the fire-resistance rated floor/ceiling assemblies described within the document.

“The STC and IIC values given in DCA 3 provide an additional tool for designers to use in demonstrating compliance with code requirements and acoustical design objectives,” said Jason Smart, AWC’s Engineering Technology Manager.

These recently added STC and IIC ratings were estimated through engineering analysis based on the empirical model described in AWC Technical Report 15 (TR 15), Calculation of Sound Transmission Parameters for Wood-Framed Assemblies, which is also available for free on the AWC website:
