Materials List Revisited

[Ed_Downunder]

Appreciate your reply Doug,

Happy with the calcs. This post was not about calculations. My fault for taking it off topic. I thought I discovered an error (silly me) What is under discussion is the way Chief reports. Chief still report all floors to the foundations. This is the type of reporting that I am discussing. Not all edge beams and slabs are poured as one are poured. Would like these items separated.

Glen: my numbers for cals:

Slab = 5 x 5 x .1 = 2.5 m
Footer = 18.6 x .45 x .35 = 2.9295
Chamfer = 18.4 x (.1 x .1)/2 = .092
Ledge = 19.44 x .172 x .14 = .468
Total = 5.053 exact

I believe the wall insulation is coming from the gap material, noted as insulation gap. If you change this material wall insulation changes accordingly.

However, attached is a similar plan using slab walls which is definitely wrong. Also, can’t figure out why chief added wall, ceiling and floor insulation on a all concrete structure and where its coming from?

[Mark]

I have found the best way to calc wall and ceiling insulation is to to completely hide chiefs numbers and make a new material for wall insulation and put it on zero thickness layer in wall layers and the same for ceilings put into ceiling structure layer again zero thickness this gives you full control over batt sizes and can be changed on a room or wall type basis

I must say all this talk about material list changes has me hoping for changes in x6 it filling me with false hope already I am disappointed

Gerry,

Thanks for the confirmation on the slab quantity.

I still maintain that the insulation is coming from the walls main layer.
I can draw the cavity brick wall with a water material for the cavity and the ML gives me bricks for both wall skins, the water in the cavity AND the wall insulation.
Even your attached plan is giving wall insulation because there is only 1 wall layer, which is the main layer and hence automatically generating the insulation.
Can you post a plan that doesn't show any insulation for the wall?

[gteacher]

Gerry,

Can you post a plan that doesn't show any insulation for the wall?

Nope -- I was kind of hoping you could show how? Can't get rid of it or ceiling ins.

Curious thing. If I change the gap to Insulating Foam Block, then I get a double count of both wall batts and blocks. Doesn't seem right?
If the gap is just wall insulation, then I only get one count.

You can go to your material list preferences and turn of insulation

That doesn't help if we have insulation elsewhere that we need included.

. i Gerry This is the definition of Gap?

Thanks Ed, That explains the sometimes double reporting - sometimes not.

Also I have to point out that Chief Does sometimes screw up the cals as per my posted plan.

At any rate, If Chief isn't aware of the problems now, they never will be. No excuses now.

[Doug Park]

Gerry, thanks for that example. It looks as if the model is incorrect and is doubling the concrete in the area that the slab intersects the wall. If you do a glass house view of it you can kind of see where the problem lies. Unchecking monolithic slab in the room specification seems to correct the calculation in the version of X6 that I'm running. I'm on a Mac right now so can't check X5.

I will need to check with our foundation guy but I don't think we should allow the use of Monolithic slab when using a wall with the slab footing property checked. My recollection is that a monolithic slab just puts a slab under all the rooms without looking at the walls. It may be possible that there are legitimate uses of it in conjunction with slab footing walls, but I can't think of any at the moment.

[Glenn Woodward]

Gerry,
Try this.
Draw a room with single layer walls.
Make 2 walls 1 1/2" thick.
Make the other 2 walls 6" thick.
Generate a ML.

You should get 2 different entries for wall insulation.
1 for the thin wall (about 4" thick which is too thick for the 1 1/2" wall anyway) and one for the thicker wall (6" thick).

This is part of what makes me believe that the wall insulation is coming from the walls main layer and not the a cavity (if there is one - because a s you can see, you get wall insulation with a single layer wall).

Either way, doesn't really matter, it needs to be fixed.

All this time wasting of Chief users in having simple area & volume calculations messed up is confusing and counter productive.

This should all be simple and logical in the way that they calculate.

Trouble Shooting these types of problems to find a work around is not published in training manuals or videos.

If you want to put the work in to try to make ML do the full job then OK.

I cant fully trust ML feature yet, so I will do it by hand and check ML list for reference only for now.

BTW I am happy with the way Chief builds timber framing with no add ons and the ML development in this area is going very well.

All the best to you work around trouble shooters for giving of your time to help others.

[Ed_Downunder]

Keep singing Scott.

You might be off key and out of tune but the lyrics hit the emotional spot!

[Ed_Downunder]

Light bulb moment. Thanks Glen. It seems that to get an accurate ML for this I have to calculate the footing as shown in the video. (I'm going to call this one a work around)

Solved - lets move on.

This may be more challenging. A new wall system we are investigating.

[gteacher]

Thanks Doug --- That clears up a lot of confusion -- at least on my part. I had no application , just exercising Chief.

I knew yous guys would come through. Sometimes we just need to get your attention. --- Thinking ML update?
