Architectural Woodwork Standards Your New England AWI Presenter:
Today's Topic Architectural Woodwork Standards 2nd Edition Your New England AWI Presenter: Norman “ Woody” Vaughn Program provided by NEAWI Planning Committee New England Chapter

AWS Edition 2 Three advanced woodworking associations have joined forces. Their combined knowledge and experience in writing industry standards have created a bold new joint standard. The Architectural Woodwork Institute and the Architectural Woodwork Manufacturers Association of Canada created a combined standard between and The Woodwork Institute in California provided valuable assistance and support during that effort as well. In 2007 the governing Boards of all three associations crafted an agreement to create the new Architectural Woodwork Standards. This Second Edition changes Section 6 from Interior and Exterior to simply Millwork. Also, note that Section 8 has added Ceiling Surfacing and Partitions to Wall Surfacing.

Goals for this presentation:
Identify key format changes and numerical referencing Discuss some of the key substantive changes within the standard Clarify the errata process, effective dates, and how those errata will be made available. Discuss how to make suggestions for correction or change to the standards Digging into the AWS with Model Questions Questions and Feedback Goals for the Presentation: Format Changes Substantive Changes Clarify Errata Process Suggestion Form Model Questions Q&A

Participant Poll: What is the most important usage of the Architectural Woodwork Standards? Bidding “apples-to-apples” with a competitor. A communication tool between the design professional, woodworker, general contractor, and owner. Knowing the minimum standards to which I can build. The answer is: All of the above.

Timeline: AWS Publications have been shipped from the printer and have arrived at all AWI member locations. Manual took effect for all projects bid/contracted on or after October 1, 2014 First errata release, January 1, 2015 Second scheduled errata release, April 1, 2015 Third scheduled errata release, July 1, 2015 Fourth scheduled errata release, October 1, 2015 Errata scheduled to follow as necessary every 6 months thereafter. Timeline for 2nd Edition Effective October 1, 2014

How the AWS changes in Edition 2
New layout Information grouped and organized: Introduction General Product Installation Tests (First paragraph is optional detailed information) Formally titled “Architectural Woodwork Standards-2nd Edition”, the AWS serves as a Standard for Materials and Workmanship which can be referenced for the Production and Installation of Architectural Woodwork. Make sure you’re using the latest edition from 2014. Information within the AWS is easier to find thanks to work done to regroup and organize the Standards much more effectively. The new AWS is divided into five areas of importance: Introductory Information, Consisting of educational materials and resources relevant to the Section that are not standards or compliance requirements and general recommendations. Next we have the Compliance Requirements that are divided into: General, which covers general information like basic considerations, industry practices, and scope of work. Product covers the minimum material, machining and assembly requirements for the Grade of work selected or required. Installation covers minimum installation requirements for the Grade of work selected or required. Tests covers ways of verifying compliance with the Standards. 7

Appendix B has been eliminated
Educational Content has been moved to Introductory Information Pages – Not for Compliance Appendix B in the First Edition has been eliminated and Educational and Instructional information has been added to the front of each section as part of the introduction. Content has been corrected to be compatible with the standards. The Introductory Information portion of each Section will not be considered Compliance Requirement. 8

Introductory pages now have three columns for easier reading
9

All Compliance Requirements Separated by Grey Headers
Page Introductory Information is primarily the Appendix information brought back to the beginning of each Section. The Grey headers are the minimum prescriptive requirements for each item.

Compliance pages all have two columns with a less intrusive numbering format
Compliance pages have been formatted for easier reading – numbering format simplified and less intrusive. Two columns for better navigation.

Compliance grid pages are much easier to navigate and show which grade is identified
E,C and P have been bolded when applicable.

Section areas have been changed –from “General, Product, Execution and Compliance” to “General, Product, Installation and Tests” Section areas have been changed –from “General, Product, Execution and Compliance” to “General, Product, Installation and Tests” By greying out areas not being used and making dark the area you are in it is much easier to see where you are in the section.

Graphics demonstrating Test Locations and a Compressed Numbering System
Page More Graphics have been added throughout the Sections- identifying test locations and examples for compliance Each Section has been separated in two – Introductory Information and Compliance Requirement. The delineation of Grey Headers for Compliance makes it easy to identify what part of each section is for Compliance.

Relative humidity SECTION 2 Page 42 2.4.4 Basic Rules Installation:
Has a maintained Relative Humidity between 25% and 55% No one wants to see this happen to their woodwork: not the owner, not the architect, not the general contractor, not the woodwork installer or manufacturer. AND YET, the movement of installed woodwork is, BY FAR, the most common problem handled by our associations. There are two ways to avoid a failure like this > 1 – keep the space between 25-55% relative humidity (for most parts of the country) OR 2 – design and engineer for wood movement.

Items of Interest Moisture equilibrium table has returned to the Care and Storage Section. (pp. 39) They finally brought this chart back into the manual, it was omitted in the First Edition. Has the wood acclimated to jobsite conditions? Although AWI requires 72 hours acclimation, how to you know when the wood is ok to install? How fast does wood move? (Note to Woody: Blow into stick)

Items of Interest Veneer wrapped profiles are now included. (pp.149)
PUR is Polyurethane Reactive.

Items of Interest Tolerances for Repairs (pp.161 and all installation sections) Although there is no change in the tolerances, they are repeated in each Section.

Items of Interest Reasonable Assessment Clause (pp.164 and all installation sections) Note to Woody (Feeler Gauge vs. Boxwood Ruler.) Wood movement not a consideration? Note disclaimer of 6.3 giving you the out?

Items of Interest Crossband at solid wood passage door edges (pp. 255)
I asked the question, Who thought this up? If you want an honest answer, this is a bad idea with the crossbanding but one Joint Standards Committee member garnered enough votes to have this place into the AWS. His personal feeling is that having the crossband covering the joint between the core and the solid wood adds to the impact resistance of the wood edge (no supporting performance data). However, seeing the crossband would be unsightly. Thus the rabbet – and the impossible construction detail. Keep in mind that it takes a 2/3+1 majority (7 of 9 votes) of the JSC to change anything within the standards. Based on the results of that straw poll, I usually say that this confirms that I still have not found another room where 2/3 of the people attending feel that this is a good idea – and that is why AWI is looking to develop the next generation of standards using the ANSI process of broad-based consensus from the industry.

Items of Interest Improved illustrations for cabinet matching requirements and definition of cabinet unit (pp. 289 / 300 and glossary) They have improved the graining for better clarification.

Items of Interest Improved illustrations for cabinet matching requirements and definition of cabinet unit (pp. 289 / 300 and glossary) Glossary page 492 definitions.

Items of Interest Joinery illustrations moved from appendix (pp ) This is a great example of moving the nomenclature and descriptions from the Appendix to the beginning of each Section to better explain and understand the following compliance requirements.

Items of Interest Transparent veneer matching requirements for casework (pp. 305 – ) Note on item 4. Always check Project Specifications to make sure you can use running match and that balance or center balance is not specified. I believe there is a slight conflict of this mention of running match from the Glossary page 504.

Items of Interest Improved organization of drawer box material requirements (pp. 306/307) Better Clarification and easier to read.

Items of Interest How to address joints in 3mm Edgebanding (pp – ) Note that edgebanded joints must be flush or set back, either way, each room must be the same.

Items of Interest How to address joints in 3mm Edgebanding (pp – ) This is a detail that was vague in the AWS Edition 1 as to the treatment of the edges of 3mm edgebanded components and whether or not they met the gap tolerances if they weren’t rounded. This gives specific tolerances or options for the square to rounded intersections of 3mm edgebanded components.

Items of Interest How to address joints in 3mm Edgebanding (pp – ) Again, this clarifies the gaps allowed.

Section 8 Now Contains Ceiling Surfacing and Partitions
Be careful here because Project Specs may relate to other Sections to our Division 6.

Wood wall panels within a project area
Section 8 Page 222 Assembly rules Running Match Custom Sequence Blueprint Sequenced It’s unlikely the design team had this in mind when they specified Red Oak paneling for this elevator surround. It could be that neither the design team nor the owner know or care how unsightly this paneling turned out to be – BUT I’ll bet a half-dozen cookies YOU care, and you SHOULD. Grain continuity is spelled out in the Architectural Woodwork Standards (AWS). 30 30

Clarification of Matching of Panels / Requirements
Page 201 Page 197 Errata 1/1/2015 clarifies the sequencing of panels within a room. This errata eliminates the use of pre-manufactured panel sets for use for sequenced Custom and Blueprint Sequenced Panels.

All Edition 1 Errata are Included in Edition 2
Page 314

Cabinet Stretchers of Particleboard or MDF are now required to be 5” in width (10.4.7.13.3)
AWS page 317

Construction and Overlay Terminology Has Changed
Page 297

Miter-Fold Drawers are now Allowed (Economy and Custom Grades)
Page 312

Sagging ¾” thick adjustable shelves
Section 10- lbs per sq ft (195.3 kg/m2) for commercial shelving. lbs per sq ft (244.1 kg/m2) for schools, hospitals, and library book shelves. For thickness and material type, refer to the chart for maximum shelf lengths. Section, Page We’ve done a good amount of research on the strength of various shelving materials. When you keep the design and engineering of shelves within the ranges shown in the AWS you will usually be fine. Anyone can overload a shelf, of course, so some common sense must apply. The QCP reviews will help catch this kind of issue early. Page

Max. Adjustable Shelf Length
Adjustable shelf loading and deflection is addressed on page 318, but the new wrinkle are the easy-to-use graphics on 319 and 320. Here you see and read the maximum length which will likely perform to the maximum deflection (1/4”) at full load. No more guessing. Of course, you can and should reduce these maximums when you want better performance, or know the client will over-fill the shelves.

Check All of your tolerances!
In all sections, most tolerances for gaps, warp, flushness, etc. were adjusted for uniformity. Tolerances in the Assembly section apply to joinery of components in the factory. Tolerances in the Installation Section (No longer called “Execution”) apply to joinery in the field and are not as “tight” as the plant assembly tolerances.

Errata The purpose of errata are for correction of errors within the standards, not for the introduction of new or substantive changes to the standards. Errata for AWS Edition 2 will be considered prior to the first month of each quarter and will be go into effect on the first day of each quarter for the next four quarters. Consideration December 1, 2014 for January 1, 2015 implementation Consideration March 1, 2015 for April 1, 2015 implementation Consideration June 1, 2015 for July 1, 2015 implementation Consideration December 1, 2015 for January 1, 2016 implementation Consideration June 1, 2016 for July 1, 2016 implementation *Note: The JSC reserves the right to implement an immediate effective date if the error results in significant industry impact.

Errata will be posted at www.aws-errata.com
Red-line versions of AWS Edition 2 will be available for purchase either as a .pdf digital file or a print-on-demand publication at the time of each scheduled release. AWI Members will be able to purchase these editions at a reduced member price through our online store. The link may be found at

Top 10 Nonconformities found by QCP Inspections:
#10 - Wall cabinet end panels that extend below bottom panel does not match exposed surface (pp. 316 – ) Note. Errata changed the numbering only on this page.

#9 - Incorrect drawer box material thickness for laminate cabinets (pp. 308 – ) **NOTE** No maximum thickness listed in AWS Edition 2. Note. There is an Errata change on wood casework for materials, but not here.

#8 - Edgebanding material does not match the Specifications (usually found during shop drawing review) (pp. 302 – 10.4) Project Specification and Architectural Drawings take precedence over AWS.

#7 - Scribe width exceeding the maximum of 1-1/2" (pp. 323 – / pp.329 – ) Scribe MOLDS are not allowed in Premium Grade but Scribe Fillers are, new to this Edition.

#6 - Incorrect Laminate Door & Drawer Front Back Material (typically cabinet liner being used) (pp. 307 – ) No change from First Edition.

#5 - Countertop sink cut outs not sealed (pp – ) Same as Previous Edition.

#4 - Dowel Spacing (pp. 322 – ) As you know, AWS has allowed cabinet members to be securely fastened together using Dadoes, lock joints, plows, rabbets, dowels, dowels screws or biscuit splines. Under the January 1st Errata, they have added the following new citation: Page Joinery other than that provided for within Section 10 is permitted provided it is fully documented in a text/illustration explanation, and each material application has been independently tested to show compliance to the minimum requirements of the Cabinet Structural Integrity Tests within the APPENDIX,

Alignment and Gap on cabinets
SECTION 10 The MAXIMUM UNIFORM GAP variance (continued) At FLUSH OVERLAY FRAMELESS construction (continued) “A” shall not exceed 1/8” (3.2 mm). “B” shall not exceed 1/16” (1.6 mm) Gap tolerances are important, both for the look and feel as well as the function of the casework. Almost all the gaps and tolerances on modern casework can be easily adjusted for compliance. The upper left picture shows non-compliant gaps and alignment. The lower right picture shows how the cabinet was adjusted for compliance. page 324

#3 - Door Adjustment (Flushness is most noted) (pp. 323 – ) January 1st Errata has changed only the text. Now reads EDGE ALLIGNMENT of doors and ….

Who is Going to Clean Up This Mess?
Thankfully, few installations fail as dramatically as this beauty solon casework. No one was hurt. It happened sometime during the night. The horrifying thought is that it could have happened with every chair filled during a busy workday. As you can see the cases were built with standard ¼-inch backs, but without hanging strips, as required by the AWS. Note that January 1st Errata has changed citation numbering on this page, from to Page 331 Basic Rules ;Casework Wall Anchorage 51

#2 - Incorrect Anchorage Fastener Location (pp. 331 – ) Same as prior slide. Note that January 1st Errata has changed citation numbering on this page, from to

#1 - Missing fasteners at 4" on center in the back panel (pp. 317 – ) “Plant-on Backs”

Recap: Architectural Woodwork Standards, Edition 2 will be effective as of October 1, 2014. AWS Edition 2 at that time will be the “current” standard, replacing AWS First Edition. There is no quick way to identify all of the changes, read and study carefully!

Recap: Errata will be released quarterly for the first year, every 6 months thereafter. Red-line versions will be available for purchase that include all errata. Suggestions for correction of errors or for consideration for future standards may be submitted online for review by the AWI Technical Committee.
