Whoopdy doo... your no where near 18 stories

Wow your angry.

It's probably dangerous to be standing in there!

In his list of references the newest was 13 years old and much was 30-40 years old. Safe to say technology has progressed since then and produces a higher quality product.



This was written in 2012, where as the glues "may" have improved the wood fiber has gotten worse.

The high quality wood fibre may have degraded from the time of his early 80's references but I would say from 2012 it has gotten better on the low quality end as logging moves from pine beetle salvage back into old growth spruce that they hadn't been harvesting for 15 - 20 years. The high quality fibre particularly douglas fir remains high quality although smaller but is processed by better mills with better and more consistent drying technology. Either way Glulam isn't the technology that is enabling this construction CLT and PSL are.

Bnorth, you are going to have to spell these things out for us prairie folk. CLT? PSL? Enable construction?

CLT - cross laminated timber (dual span direction allowing them to support themselves between columns without beams)
PSL - parallel strand lumber
Supposed to minimize uneven shrinkage of timber in columns. Also they used steel plate connections at certain floor levels to minimize movement

From a fire code standpoint,this building is a disaster waiting to happen. Yes, you can cover the wood framing with fire retardant materials, but the fact remains that the structure holding up the wooden floor structure is a made from materials made of glue and wood, both of which burn well and when combined burn very hot. Living in that building not only are most of the contents of the building made from synthetic man made materials ( like most house contents) but the building as well is constructed of synthetic materials that burn quickly and very hot.
Im sure it will have a sprinkler system installed, but just imagine what a bunch of water and steam released into that structure will do to it. As long as nothing bad ever happens in that building, all will be well, but if the worst should happen, it’s not gonna be pretty.

You got a good point. Maybe they used this fire retardant. https://treatedwood.com/products/d-...q0tIE5LJB30AoYeuW6j827sIlqAMLcyRoCC18QAvD_BwE
Does it work?

Don’t know, but I’m sure any fire retardant materials are better than nothing. As always the big question is cost. It’s only gonna get used if it’s a code requirement. Otherwise the builder will go as cheap as possible as usual.

 

[S.W.A.T.]

From my understanding the adhesive used to laminate the wood is supposed to fire retardant in its self. I don't understand why something like this is seen as a bad thing. Its farm more stable then 2x4

Well I just used 1000’ of glulams , should have checked with the snow and mud engineers before we started. lol.

yup, you know there are more experts and professional's on this site......guys who know more than your engineers........I hope you've learnt your lesson and check here first before you build another disaster.....sheesh.....

kidding of course....I love looking at the pics of your building projects

New building Code are out as of April 1 in Alberta. They are allowing these projects.
