	DCA 1 - Flame Spread Performance of Wood Products Free Download - PDF Provides building code accepted flame spread ratings for various wood products and species which are normally used as interior finishes for walls, ceilings, and floors in buildings. AWC is in the process of updating DCA 1. Your input regarding use of this information in the market place will be helpful during this revision process. Click here for the 5 question survey.
	DCA 2 - Design of Fire-Resistive Exposed Wood Members Free Download - PDF Illustrates how exposed heavy timber and glued laminated columns and beams can be designed to meet building code fire resistance requirements. Also see TR10 - Calculating the Fire Resistance of Exposed Wood Members. Fire Resistance of Wood Members with Directly Applied Protection
	DCA 3 - Fire Rated Wood Floor and Wall Assemblies Free Download - PDF Describes how interior and exterior wood-frame walls and wood I-joist floors can be used to meet building code requirements for fire resistive assemblies. Additional information:
	Calculating the Superimposed Load on Wood-Frame Walls Performance of Finger-Jointed Lumber in Fire-Resistance-Rated Wall Assemblies Additional assemblies not shown in DCA 3 - 2005 ASD/LRFD Manual for Engineered Wood Construction Chapter M16. Meeting the new requirement for membrane protection in the 2012 IRC
	DCA 4 - CAM for Calculating and Demonstrating Assembly Fire Endurance Free Download - PDF Describes a procedure to calculate the fire endurance rating of a wood-frame wall, roof, or floor/ceiling assembly. The procedure is based on combining previously determined fire resistance time values of each separate component of the assembly without the need for additional fire testing.

Structural Systems Section

DCA 5 - Post-Frame Buildings
Free Download - PDF
Provides guidance to post-frame building designers for meeting the requirements of the 2000 International Building Code and to confirm that a properly designed post-frame building is in fact code compliant.

DCA 6 - Prescriptive Residential Deck Construction Guide - 2009 IRC Version
Free Download - PDF*
Includes guidance on provisions of the International Residential Code (IRC) pertaining to single level residential wood deck construction. Provisions contained in this document that are not included in the IRC are considered good practice recommendations. Based on the limited number of changes to deck provisions in the 2012 IRC, the DCA6 2009 IRC version can be used in jurisdictions enforcing the 2012 IRC.

Learn about DCA 6* changes here.

Building officials may print a reasonable number of copies of DCA 6 for use with permits.

*Please Note: The entire DCA 6 cannot be posted to a building department website.

Updates and revisions are frequently being made to the document so it is recommended that building departments post a link (http://www.awc.org/codes/dcaindex.html) to DCA 6 on their websites. Also, AWC has developed a one-page PDF that can be posted to the jurisdiction’s website to provide an overview and links to the AWC document.

AWC also offers a free Design Professional Membership to qualified building officials.
