Subject: DBUG› pressure treated and fire resistant wood

There is nothing better than steel for this. If it's light gauge then you can even put nails through it with a gun that uses a cartridge.

You can get single shot or multiple shot ones pretty cheap.

When in doubt use steel. Its a lot easier.

I suppose, as with any architectural challenge, one must UNDERSTAND THE PROBLEM before attempting to hurl solutions at it.

As those of us in the Peanut Gallery do not have any significant information, we will not be of any help.

Using fire-retardant treated lumber is a fairly rare thing. The ONLY times I've used it are when plywood or various blocking has been necessary in Type I and Type II non-combustible structures. Not needed in any other Construction Type, even in fire-rated construction, usually.

If you have water/moisture in your assembly to where preservative pressure treating is necessary, you've much bigger problems. Termites, of course, are a whole 'nother story. Preservatives are, at their core, poisons. Alas, the best poisons are behind us. I've applied barrels of the 'good stuff' back in the day. Yay.

I use truckloads of pressure-treated woods, both for fire and for preservative treatments. Always separate, however.

A couple of years ago, I had the onerous challenge of replacing a roof of aged 1x12 wooden planks. Can't do that in California. No longer legal, at all, with no means around it. What to do? Well, I pulled molds from rugged wooden planks of the size needed. Several different ones. Then sprayed custom-tinted concrete into each, followed by spraying layers of concrete with chopped glass fibers, adding fiberglass mat in the middle, more sprayed concrete with chopped fibers. 11,000 PSI mix. Result? Glass-fiber reinforced concrete planks that mimic the look of the boards that were their parents. Non-combustible. Fungus & termites won't go near it. Ought to last for a century or so, I figure.

Note that there are also pultruded fiberglass products that may be of use. SOME of those may be available with fire-retardant resins (you'd have to research that). While "studs" may not be available, channels and MANY other structural shapes are. We commonly use such in damp environments. Even underwater. Very easy to work with and assemble. This may prove a viable option for you. Great stuff! Here's one MFR:

Chris Walsh died last night. My condolences to his family.  He will be missed.


"An architect by trade and the House vice chairman of the Committee on Education, Walsh was first diagnosed in July 2015 with non-Hodgkin's, small lymphocytic lymphoma and he underwent treatment at Dana-Farber Cancer Institute."

@Neil Just do an energy study with 1/2" energy board on the outside and you should be good even in New England. You can use poly iso foam if need be.

Hi David, 

The new energy code requires 2" of continuous foam, which makes it 
difficult / impossible to then fasten Hardie siding.  We also have to 
meet fire code, since the building close to the property line.  We are 
using rock wool insulation, and thermally broken metal framing.

I've never had to use FRT framing in wood fire walls. What's up with that?

I routinely knock out 1, 2, 3 & 4 hour rated fire walls & fire barriers, for various purposes. 4-hr walls with 3-hr automatic-closing opening protectives are fun.

Trivia: My very first freelance paying job, as a kid in junior high school, was to design and draft a code-compliant fire wall for a huge pole barn that a pallet manufacturing company had built too close to their property line. Busted, the City of Los Angeles Code Enforcement Official hit them with a Notice to Correct. Mr. Thyne, owner of the company, placed an ad in the local fish-wrapper. I bit! Early Seventies.

Sometimes per IBC 602.3 & 603.1 you can use it in Type II & III where otherwise you would have to use non-combustible materials.  Just another option.

James,

I suspect you must be pulling our legs with this question, but suppose even you might not be aware of this.  Under IBC codes since at least 2009, for Type III construction, although exterior walls are nominally required to be of non-combustible construction, FRT wood framing (and sheathing) is permitted.  This allows Use Group R2 wood framed multifamily housing to exceed the height limits of Type V construction.  I'm currently working on a development with 5 residential stories above a Type I parking structure, which is only possible using Type III or higher construction.  There are plenty of wood frame fire rated walls, but where non-combustible framing is required normal lumber doesn't cut it (no pun intended).

I'm sure we all did a lot of things in the 70s (and 60s) we might not even consider today, that might not even meet code today.....  I can think of a few I'd rather not talk about.
Best,

Mark Wilhelm

I'm with ya.

Nearly all I do is non-combustible. Aside from retrofit and repairs to existing wood-framed stuff.

I use FRT in non-combustible, properly.

Now, had the entire problem statement been clearly delineated, potential solutions might have manifested faster and more on-point.

Reminds me of a client I had ages ago: Every time he'd walk into the office, the dude would ask, "How much does a tilt-up cost?" I grew to loathe that dude.

DBUG> Data Cad error message and Crashing
Date: May 11 2018


Hello, 

I'm writing this message seeking help to figureout what happened to our DataCad file. We are using DataCad 13 and yesterday. the file has crashed when we go to plot command. Also if I draw line or do something it generate error message#736 and #808 is there is any idea why this happened and how we can solve it,, Thank you for any help you do. I appreciate it

        Hover for 3D Models, FreshBooks, and Up with Trees

* Light Dinner Refreshments ($5 Donation for buffet) Reception & Networking

* Welcome, Introductions, and General Announcements (updates on any DataCAD developments)

* Surprising Tree Removal Services
    by Evan H. Shu, FAIA
The Winter Storms caused a lot of tree and property damage. Evan will give you his video story of the removing of 3 huge backyard trees in a surprising method that involved not so much cutting them down and cutting them upward. You have to see it to believe it.

* Hover software for Photogrammetry
    by Greg Barriere, AIA / Barriere Design Associates
We have long talked about the day when true photogrammetry arrives, when the taking of a few photographs around a building can result in true CAD model being developed automically. That day is already here. Greg will demonstrate how he has used the latest software in photogrammetry using the Hover app that will give you a true, measurable, customizable model directly from taking photographs around a building. The Hover app provides very detailed building information which helps contractors and clients communicate material changes & alternates with detailed measurements, making accurate cost estimates possible.

* FreshBooks -- Accounting Software for Architects
    by Anson Courtright, AC-Architect
FreshBooks is simple and intuitive software that automates many of the tasks around invoicing, organizing expenses, tracking your time and following up with clients. Anson will show us how he uses this software in his architectural firm and how it has made accounting tasks much easier while letting you know both the pros and cons (or workarounds) of using it. 

*Notes: AIA Members & Massachusetts Registered Architects can earn 2.5 CEU credits for attending.
