Do you have any evidence that this is, in fact, the case? I have not seen any such evidence, and to the best of my knowledge, everyone who has reported this has a valid licence. I know that I do. I experience erratic mouse behaviour with X-13 that I never experienced with X-12.

Framing groups doesn't help with this problem unless you frame the interior floor, then change the "ballooning" attribute for the rear wall, then frame the deck, and make sure that you don't have automatic floor framing turned on at any time or command the floor framing to be rebuilt.

Using ballooning walls results in some unfortunate side effects on the inside of the building. Note that in your posted picture the inside floor terminates before the foundation wall.

Quite often the footing will cut through the floor slab with a very short stem wall or curb for the load bearing wall to sit on. This accomplishes several things. 1) There is a clear limit for where the framed wall above the curb can be placed. 2) It is clear to the inspector that the wall is intended to be load bearing. 3) The bottom plate is kept dry in most conditions.

That works for the deck, but results in a very strange floor platform for the rooms inside.

Nice solution!

Rick, please post the plan, so that someone can explore all the settings.

This post moved to suggestions.

I use a Brother MFC-J6945DW Printer, which will print 11 x 17 copies in colour. The printer was less than $500, has two media automatic feeders and will scan 11 x 17 as well. This size is pretty useful, and covers about 95% of all my client paper needs, and most applications that still require paper copies. Ink is not out of this world expensive either. I still wish that I had a 24" wide printer though, even though realistically it wouldn't pay for itself.

SB-9 Requirement for Soil Gas Control.rtf I have scanned a copy of SB-9 in the Ontario Building Code for Soil Gas Control The only part that I can see that mentions where the radon vent is to be located is near the CENTRE of the FLOOR, not the centre of the room. This could actually be worse for you. 3.2. Providing for Subfloor Depressurization (1) Except as required in Sentence (3), granular material shall be installed below the floor-on-ground according to Sentence 9.16.2.1.(1) of Division B of the Building Code.(2) A pipe not less than 100 mm in diameter shall be installed vertically through the floor. at or near its centre. such that (a) its bottom end opens into the granular fill described in Sentence (1). and (b) its top end will permit connection to depressurization equipment....

This unintended stair shelf is common in lots of houses. Sometimes this is addressed by adding a false wall on the shelf in the stairwell to make the wall look continuous, but that results in a void behind the wall. This could be filled with extra insulation or used to hide ducts or piping. If you do renovations, you're bound to find these "shelves" in lots of northern homes (houses with basements.)

I would create a ceiling plane below the stairs to get sufficient insulation that would match the suite floor insulation thickness, not that it is require, but it sure would make good thermal sense. I have a BCIN HVAC designer who would do the building calcs, supply design forms and drawings for you for about $500 or so. Adam Carter 1 905 419 1961. Canada HVAC Design. http://canadahvacdesign.com/. canadahvacdesign@gmail.com I am sure that Adam can make some recommendations that would suffice.

I would have a discussion with the plans examiner. The area under the slab is all connected, so it shouldn't matter where the radon rough in is located. (I am assuming that the rough in goes through the slab on grade.)

Where the heck did you snag a RTX 3080??

Does Alberta use the National Building Code? In Ontario we have our own version (OBC) with lots of goodies added onto it just to make live unbearable. SB-3 for fire rated wall and ceiling assemblies and sound transmission indexes are very helpful though.

Maybe put in in the furnace room and mechanically vent to room to the exterior. None of the air in the furnace room should get into the occupied space because of the HRV. The tough part comes when they do a radon test and find that you have to vent the gas, and then you need to go above the roof!

I have another question for you. How is the radon gas rough in accessed?

Your welcome Chad, glad to be of assistance.

Ryan, I agree that roof returns can create great and varied returns, unless I am missing something here, that won't work in this case. My model, in answering the challenge, is pretty sloppy, but I did it in a few minutes just to see a method for answering the OP problems. I posted my working file, just so that the working method could be examined. This is pretty much a manual roof job.

Thanks

How much do you charge? This is really interesting.

Holy Cow this looks like a complicated project. Not just for the design, but the construction as well. As for the blurry image, have you updated your PDF printer drivers? Are you using the native CA=> PDF exporter? I use Kofax Power PDF Advanced as my PDF tool of choice (it creates PDFs, edits PDFs, allows signatures, converts PDFs to MS documents etc. I don't experience this problem using that application. Mybe you should post the plan file. The actual PDF output file, and, just beating Solver to the punch here, fill out your signature so that other members can see what version of CA you are using, your hardware, OS etc. It helps us to further diagnose problems and offer better solutions, or (shudder) work-arounds.

Which printers are you looking at? I have toyed with a wide format printer purchase for a few years now but the cost still causes me pain. How do you get a payback on this Rob?
