NADRA Code Update

July 3rd, 2019

By: Glenn Mathewson

To finish a marathon, you’ve got to push through the last mile.  Such is the same with developing a new edition of the International Residential Code.  Thousands of people are currently running a marathon toward the 2021 IRC, and though they are halfway through, there’s no telling who (or who’s proposals) will make it to the finish line.  While it’s too soon to start cheering, it’s not to soon to feel confident and strong, and that’s how the NADRA and Deck Code Coalition proposals are looking.

With the publishing of the final report from the Committee Action Hearings, the public can not only see the results of the hearing, but also a summary of the comments made by the committee.  There are three result categories, but since those aren’t “final” results, the comments should be the focus.  The committee comments could be looked at as spectators cheering on or booing the runners.  They provide direction, encouragement, and suggestions, much like “you got this! Keep going! You’re so close”.  Unfortunately, sometimes the comments can feel more like “you’re never going to make it! Give up now!  You look so tired!”

The race is not over until you pass the finish line, and sometimes people get a second wind.  That’s what the next phase of the code modification process can offer—a second chance.  Regardless of the committee result, every proposal can receive a public comment modification, and if received, the proposal will be heard again at the final hearings, where a final vote will be made…but not really.  The final vote is actually made online a few weeks after the hearing.  In this vote, only governmental ICC members can cast the final thumbs up or thumbs down.   These members could vote down a proposal approved by the committee, and likewise, the members could turn around a proposal disapproved by the committee.

Public comments to the committee results are due July 24th and these will be the catalyst for the next step in the process.  A proposal that does not receive a public comment is almost certain to be finalized as-is in the “bulk vote” where the governmental members vote for the entire package of proposals.  Having not received any disagreement from the public, the assumption is that the committee opinion is good to go.  Here is the part to pay close attention to:

If the committee result for a proposal is not challenged by July 24th, consider it done.  If there is something you don’t like, silence is equivalent to support.

So let me put it this way…  “Speak now or forever hold your peace”.

Okay…that’s not exactly true, but you would have to hold it until the 2024 IRC code development hearings where everything is on the table again.

Thanks to select NADRA members that have financially supported NADRA representation in the code modification process, I am working alongside other professionals in the Deck Code Coaltion and we are preparing public comments.  We are running this marathon until the end.  I hope you are on the sidelines cheering us on.  Here are the results and comments from the Committee Action Hearings that have us in a runner’s high.  You can view all the Group B ICC documents and the live video from the Group B hearing at this link:  https://www.iccsafe.org/products-and-services/i-codes/code-development/

RB184: Disapproved

Committee Reason:  There were multiple corrections expressed in a modification that the committee felt was too extensive. The wording in Section 507.4 is confusing. The committee urges that the corrections should be brought forward in a public comment. The collaborative effort, and inclusion of engineers in the effort, was a positive aspect for this proposal. (Vote: 10-1)

RB185: Approved As Modified

Committee Reason: The modification to Section R507.10.1.2 removed ‘approved’ because this adjective cannot be applied to manufacture’s instructions. The modification to Section to R507.10.2 reworded the two sentences for clarity. The modification to Section R507.10.4 removes ‘approved’ because this would be confusing to the homeowner. The proposal provided good general prescriptive language for guards that will reduce the need for engineering of guards. The committee had several suggestions for better wording that should come forward in a public comment: Add ‘also’ to Section R312.1.4; ‘design’ instead of ‘construction’ in Section 507.10; revise ‘prevent’ to ‘limit’ in Section R507.10.1.1; joists are part of the deck framing, so the language in Section R507.10.1 is confusing. (Vote: 9-2)

RB186: Approved As Modified

Committee Reason: The modification restores rivets and puts in the term ‘glulam’ to be consistent with the term used in ASTM F1667. Adding the Class D is appropriate for this product. (Vote: 11-0)

RB187: Approved As Submitted

Committee Reason: The committee felt that the overall proposal is a good reorganization that add clarity to the code requirements. Item 3 in Section R507.3.3 is an alternative means that is currently allowed in Chapter 1. (Vote: 11-0)

RB188: Approved As Submitted

Committee Reason: This revision will clarify the engineering option for deck beams where fastened together. (Vote: 11-0)

RB189: Approved As Submitted

Committee Reason: This change clarifies the cantilever limitations. (Vote: 11-0)

RB190: Approved As Submitted

Committee Reason: The proposed footnote allows for a design that does not use the full cantilever, which will allow for a more efficient design. If you do not use this option, the table is more conservative. The commentary should include an example. (Vote: 11-0)

RB191: Approved As Submitted

Committee Reason: The revisions add clarification to the code and allows for better design practice for wood decking. (Vote 11-0)


NADRA Code Update

ICC Committee Action Hearings, Group B Codes – Albuquerque, 2019:

May 2nd, 2019 Update – By: Glenn Mathewson

Deep into the IRC Committee Action Hearings. So far the deck industry has been well represented by The North American Deck and Railing Association and our friends in the Deck Code Coalition.

Preview of our accomplishments as the voice for our industry:

  • Guard and handrail load requirements were approved to be split into two columns which sets the stag to better evaluate the unique job they each do.
  • Raising the minimum design live load for decks from 40 psf to 60 psf was disapproved.

This is just the beginning of the process though, as public comments and the Final Action hearing can still change everything, MUCH work is still to be done. Please consider making a pledge today to help NADRA continue to have representation at these critical hearings. Learn more about our fundraising initiative HERE.

Today will be another long 11-hour day of testimony, but I’m proud to be here speaking on behalf of NADRA and for all those that work in decks and rails!

NADRA Code Update

February 2019

By Glenn Mathewson

Thanks to the support of NADRA members we have shared our knowledge with others in the campfire discussions regarding deck code proposals for the 2021 International Residential Code.  There were 9 proposals submitted with our assistance and approval. The Deck Code Coalition is an informal group of generous professionals from a variety of backgrounds. Led by the steadfast efforts of Mr. Charles Banjai, a now retired code official and long-time contributor to code development, NADRA was able to work with these professionals toward well-developed deck codes.   While some disagreement remains and some is yet to be decided, it appears the majority of these proposals have broad support. Here is a brief rundown of what was submitted.

  1. Decking spans for single-span and two-span conditions.
  2. Ledger, joist, and beam design tables up to 50, 60 & 70 psf snow loads.
  3. Beam cantilever wording corrected.  Mostly clerical.
  4. Relocation of footing depth and frost protection provisions.  Mostly clerical, so interpretation can be more consistent and understood.
  5. Separates guards and handrails on the load table so future, more appropriate, minimum design loads can be determined for each independently.
  6. Provisions requiring guard post attachment to be secured to adjacent members in the deck framing.  Sets minimum guard post at 4×4 and with no notches permitted.
  7. Clarifies that multi-ply beams must be fastened together.
  8. An adjustment factor to allow longer beam spans when the joists do not cantilever beyond the beam and for various distances of cantilever.  This will allow more flexible use of the beam span table.
  9. Add an appendix for guard post connection details and for future provisions regarding specific deck designs.

While this milestone in the code development process is exciting, it’s just the beginning.  Anyone can submit a proposal and there are plenty of people interested in decks. Here are the next steps:

  1. On March 4th ICC will publish all of the proposed changes.  Previous years leave expectations at well over a thousand pages of proposals to review for deck-related provisions.  
  2. Once identified, the membership will need to decide. What’s good, what needs work, what is dangerous?
  3. Research and communication with others follows.  
  4. Then reaching out to the proponents of topics of concern to share and discuss, in hopes that agreement and compromise for better code can be achieved before the hearing.  
  5. Before the Albuquerque hearings this May, testimony has to be prepared in hope as the winning words for the committee.
  6. After these preparations, the hearing will commence and it will end, and the committee results will be published.  
  7. Next, all the research and networking will happen again as public comments are prepared and submitted.
  8. This is only to be followed by all the public comments being published and the review of all the surprises will begin again.
  9. Finally, all will conclude at the final hearings in October 2019.

If you are in the decking industry, we need your help.  The ideas are being discussed and the rules are being made.  You shouldn’t stand on the sidelines any longer. We need you in the game. There are two ways you can help in a big way.

1. Offer your time: To volunteer time, please email Info@NADRA.org and we will work with you and the code committee to see how we can best utilize your skills – most likely, helping to review the proposals in March.

2. Offer your monetary support: To contribute to the fundraising initiative, follow this link here to see what our goal and how the funds are being used to keep this effort moving forward. 

NADRA Code Update

Here’s a run down of proposals likely to be submitted Jan. 7th with the combined support of nearly all the contributors of the Deck Code Coalition.  I am proud of NADRA for being a part of this support.

By Glenn Mathewson

At the annual meeting in October, it was announced that I was prepared to work for NADRA and the decking industry to represent them in the development of the 2021 International Residential Code.  I know it’s hard for most to wrap their heads around the idea of changing the 2018 code already, considering it doesn’t even have widespread adoption yet. That’s why you’ve hired me, and I’ve already gotten to work.  The best place to begin that work was to contribute to the Deck Code Coalition, an unofficial coalition of the most powerful interests in deck code. Organizations such as the NAHB, SMA and AWC are involved. Code officials from multiple ICC chapters, product manufacturers, engineering firms, and many other professionals from various backgrounds are also there.  Where is there? It’s an imaginary campfire with all interests sitting around together, sharing, talking, contributing, arguing at times, but yet no one has been thrown in the fire. This is how code should be developed, with the overall interest being the people…the end user. I believe the efforts thus far, thanks to those members that have financially contributed, have been more successful than I expected.  

Here’s a run down of proposals likely to be submitted Jan. 7th with the combined support of nearly all the contributors of the Deck Code Coalition.  I am proud of NADRA for being a part of this support.

Are you shocked by the new minimum14-inch diameter footing/pier required in the 2018 IRC?  If you haven’t heard, even the four footings under that small stair landing must be 14 inch.  We expressed our concerns of this to the DCC and the American Wood Council (AWC) agreed and re-engineered new minimum footing diameters for the table.   How does a minimum 8-inch diameter sound for those little landing? Well, that’s what is being proposed and supported by the DCC. Had NADRA not expressed our concerns, no one was going to address it.  The AWC deserves a big thank you for their engineering work.

The new beam, joist and post sizing tables first included in the 2015 IRC only handled regions with up to a 40 psf snow load.  Through significant effort from the AWC, new larger tables have been engineered to handle snow loads of 50, 60 , and 70 psf. This new code, if included in the IRC, won’t help out for all regions, but for the snowier regions that were left with nothing but job-specific engineering, this provides a much more affordable design option.

Poorly written code is hard to understand, makes the industry it addresses look ignorant, and lends itself to inconsistent interpretation.  Changes to the exceptions for footing sizes and frost protection were left pretty messy in the 2018 IRC. A proposal that reorganizes those provisions will make the code much easier to read and understand.  While this may not seem like a big deal to many, rest assured, it’s worthwhile work.

Guards and handrails are like peanut butter and jelly, they are completely different, but often end up in the same sandwich.  Guards along stairs may include a handrail feature at the top, or they may support a handrail at the side, but serve a different function and must resist different loads and load directions.  The IRC has always lumped these two features together in the load table that specifies the load and load directions they must resist. With recent testing and validation for guard strength, manufacturers and others have published many details for how to build guards.  NADRA has long stood that before work is done to design guards to resist the code-specified minimum loads, those loads should be re-evaluated. In my research of minimum guard loading over the last 5 decades, it’s clear to see that the target loads have been a “best guess”.  After attending a meeting with the American Society of Civil Engineers (the authority on design loads) and supporting efforts by the NAHB, we are proud that a proposal to separate guards and handrails in the load table and address the direction of loading for guards more specifically will be submitted by the DCC in January.

On the same subject of guard loading, we have worked diligently to help other interests in deck code understand what we understand about guard design.  It’s creative and unique and that’s what “the people” want. Reputable professionals have a strong motivation to see a specific guard post connection detail illustration with proprietary hardware devices in the pages of the IRC.  The intent is good natured and understandable. Inspectors have long had nothing but a push on guards as their measure of code compliance (safety), and that can leave anyone with that responsibility a little uneasy. They too see the news of the failing decks across our country.  This is respectable and understandable. However, builders are equally uneasy about another “picture” being put in the code that appears to universally require proprietary hardware and a specific method for post attachment. Remember the lateral load anchor? How can you forget? It’s false flag and illusion of a complete lateral load design have forever changed the industry, and still today, 10 years later, it’s only “permitted” not “required”.  A picture is worth a thousand words, and for many inspectors there’s no need to read the permissive words if the seemingly required picture is there. We can’t see this happen to guards the same way it happened to ledgers.

The will to address poorly built deck guards in the IRC is strong and has made two attempts at guard structural design code in the last two editions.  To do this work respectably, no one should have everything their way. While NADRA has incredible experience with boots on the ground, we don’t know it all.  If we appreciate the experience from other professionals when we agree, then we must also respect their experiences when we disagree. With this humble philosophy comes respectable code.  Code that was carried to the hearings in many loving arms is far greater than code pushed in with singular, selfish power. Compromise has to be made by all, so NADRA took the first step. To respect the concerns of others and hope they return it with respect for ours, we entertained new code language to prohibit some of the notoriously insufficient guard designs.  Minimum 4×4 posts for guards will eliminate some shoddy 2×4 posts that can be found. Notching of 4×4 posts in guard construction has been done for all of time, and though it works in some rare cases, it generally does not. Research has been done on this subject, and the proof is pretty clear. To help show our willingness to address this common mode of guard failure, NADRA has thus far agreed to support a prohibition of notching 4×4 guard posts.  Other proposed code language includes clear instruction that the guard posts must be secured to adjacent joists and transfer the loads into the whole deck, not just the rim joist. We were careful this language didn’t specify “blocking” that could interfere with deck drainage systems. We also made sure to exclude any mention of proprietary hardware.

It was our hope that by taking the first step to compromise and draft code language to address guard safety we would encourage others of the same teamwork and they would withdrawal their proposal for a “picture”.  Unfortunately…we were unsuccessful. Though the DCC was able to agree on 6 proposals, including the one we compromised in, select members have announced they will still propose the “picture” and we must battle it out at the hearings.  To say I’m disappointed is an understatement, and to say I didn’t lose a little respect for those professionals would be a lie. The code must represent all professional experiences and be the best mix of them all. Period. The professionals contributing to the DCC bring enough experience and spent enough time sharing it together, that any proposal that could not be agreed upon by all, is a proposal unfit for the hearing and for the code.  Period. No exceptions. In bringing the voice of the decking industry to the code development process, we must do it with as much respect and understanding as possible, and we can only hope to receive it in return. Alas, NADRA will need to take that message to the hearing and be sure the attendance knows that the guard picture proposed next year is lacking the support of many professionals.

Now for the bad news… Helping with these 6 proposals is only a slice of the work to be done.  They are simply the proposals we could contribute to before the hearings. On January 7th of next year, thousands of pages of proposals will be submitted and they will likely contain many deck-related proposals we have yet to know anything about.  NADRA must be prepared to comb through these proposals when they are published in March. I’ve heard some rumors of two proposals to expect. One to require the same additional load on deck boards that stair treads must resist.  Notice how with most plastic composite lumber you can’t span as far on stair treads as you can for deck boards? A max 16-inch span for decking is often reduced to 12 inches on stairs, but not if that proposal wins. Of course every single max span you have come to know could change with this next one.  A proposal from a powerful proponent is likely to be submitted, one that would raise the minimum design live load of 40 psf to 60 psf, but just for decks. Not the floor inside the house.

Did you hear those last two?  Ready to change all your design norms?  Ready to retest all your manufactured decking?  Are you ready for singular powers that don’t manufacture, sell, or build decks to tell you how to do it? When was the last time you had a deck built to 40 psf collapse under load? Not due to some construction flaw.

These last few months of 2018 have proven the necessity for NADRA to have funding to represent the industry in code, but the work has hardly begun. Much is still needed of the membership if NADRA is to continue contributing to this work. Your help is needed.

Major changes to ICC Guardrail Performance Criteria – Additional testing methods plus safety factor increased on AC-273

 

 

Update from NADRA’s Code Committee: 

You may have read this last week in our release revealing these new rules or criteria changes from ICC, however we feel it is necessary that we get the word out about these changes once more; and help bring clarity to the subject. This is an overhaul to AC-273 with big changes. These changes require manufactures and testing agencies alike to alter their testing methods to additional trials such as resembling “worse-case scenarios” to calculating scores with a grander safety factor. We urge everyone to take the time and get to know what is required; and contact your testing agency on how these changes will affect your railing (guardrail) program.  In addition, many in the industry have been discussing the likelihood that similar changes may be impending to AC-174; if you have any information on this please contact the NADRA code committee.

Your NADRA Code Committee has posted the statements of both NTA and ADI (Intertek) . See attached statements below:

Significant changes to ICC-ES AC273 for Handrail and Guards by NTA. Click to enlarge. 

Significant changes for metal guardrails ICC-EC acceptance criteria (Ac273) for metal guards by Intertek. Click to enlarge.

Reminder to all Handrail and Guard Manufacturers

Reminder to all handrail and guard manufacturers, in June 2017 ICC-ES approved significant revisions to AC273, Acceptance Criteria for Handrails and Guards.  NADRA recommends if you have an evaluation or code report for your product in accordance with this acceptance criteria you should contact the agency providing the report on how these changes will affect you.

In addition, due to these changes in AC 273, your Code Committee is interested in your input for discussing possible similar updates to AC174.

If you have feedback and information on your positions please send into: info@nadra.org where it will be forwarded to the NADRA Code Committee.

AWPA and ICC Approve New Treated Wood Standards

NEWS RELEASE

Info@NADRA.org
 

 AWPA and ICC Approve New Treated Wood Standards

ICC-ES AC326 – The  ICC final effective date of implementation is July 15, 2016.

Quakertown, PA (February 16th, 2016) Many of you may or may not be aware of the discussions that have been taking place regarding potential changes to Treated Wood Standards moving many structural and critical items to a Ground Contact treatment retention level.

Those New Standards have now passed the AWPA (American Wood Protection Association) and the ICC (International Code Council). The ICC final effective date of implementation is July 15, 2016.

NADRA’s mission is to provide a unified source for the professional development, promotion, growth, and sustenance of the Deck and Railing building industry in North America so that members can exceed the expectations of their customers.

This mission includes the promotion of proper deck construction, deck safety and ultimately serving the best interest of the consumer. While the Association is made up of professionals from all industry segments, we are aware that consumers use a significant amount of treated wood in DIY projects. The consumer is usually not knowledgeable enough to be able to know the proper uses for which treated wood product they are buying and therefore misuse and misapplication can occur.

Ground Contact treatment is necessary for physically above-ground material when:

  • Soil or other debris may build up and stay in contact with the wood
  • There is insufficient ventilation to allow air circulation around the wood
  • Material is installed <6 inches above the ground
  • Material is installed in contact with non-durable untreated or older construction with any evidence of decay
  • Wood is subject to frequent or recurring wetting
  • Wood is used in tropical climates
  • The wood is both:
    • Difficult to maintain, repair or replace and
    • Critical to the performance and safety of the entire system

Joists and beams for decks and docks fit both of these final criteria and therefore require Ground Contact treatment. Other Ground Contact applications include Ledgers, Posts, Step Stringers and Decking used at Ground Level and on Walkways.

ICC-ES AC326 Sample Table - The ICC final effective date is July 15, 2016

NADRA looks forward to the implementation of the New Standards as a step forward in the industry to providing those who enjoy Outdoor Living with a better, safer improved product and experience.

Connecting Deck Ledgers to MPC Wood Trusses

Connecting Deck Ledgers to MPC Wood Trusses

The connection of residential deck ledgers to MPC floor trusses is not covered by the 2012 IRC (Table R507.2 and R507.2.1) that gives fastener requirements for the connection a deck ledger to a solid-sawn house band.  The ledger connection is especially difficult when the deck ledger is attached to the side of the truss because only the narrow edge of 2×4 truss chords and webs are present and not suitable for installing the typical ½-inch lag screws or bolts.  According to Professor Frank Woeste, Virginia Tech University,  it is critically important for contractors to verify the existence of a solid-sawn band joist when adding a residential deck because without verification, it’s possible for the ledger connection lag screws to only penetrate the wood sheathing, typically 15/32-inch thick.  Details for connecting a residential deck ledger to floor trusses have been updated and published by the SBCA(2015). See HERE.
