Window and Door Trim
Posted by: craig.parker
How are folks dealing with this? The house I’m working on will be easy - everything is just picture-framed (mitred), but I wonder if there’s a way to quickly say “3x5 window” and 16’ (plus some waste) gets attached to it.
I’m thinking I’ll have to build a bunch of little assemblies (3x5, 2x3, 3-0x6-8, etc.) and have a count takeoff for each sized window/door, and corresponding assemblies attached to them.

This is how I do my interior trim. If you are using both 5/4 and 4/4 stock this could be expanded to suit this. Obviously this only does pricing and not a material order. For us, this works. We are just doing big spec homes and the interior woods are usually not selected when I’m doing pre-con. We are always buying rough stock and milling our own trim in our cab shop. This assembly is set up for Euro Beech (you can see the length is set for 12’). If we were doing afromosia I’d have to change this to 8’. One day I should make the stock length a user defined variable.
Doing material orders like this are tricky because of waste and drops. That is why I still do my siding flashing stick counts by hand. I use stack to do all the linear take offs but then I mouse hover on them and do the stick counts manually.
To develop a SF pricing item for this just get a quote from your supplier for one stick of each size material. Then do the math to figure the cost per SF. It will vary slightly from size to size but probably not so much that you can’t make a safe, all in cost per SF. I’m thinking MDL or the like here.
For stain grade material either expand this assembly to do $/LF or extrapolate this to SF. If your material is ordering in as random length, extrapolate the BF $ and run with that.

I use these for my interior trim. We are always milling our own trim hence the BF option. For regular trim, ie MDF, ask your supplier for a price quote for one stick of each size. Although you may see some pricing variation at $/SF by doing this you can probably get a good all-in $/SF to use in the item library. You’ll notice that my lengths are set for 12’. This is for Euro Beech. Afromosia would be 8’. One day I may make the feedstock length a user defined variable. I estimate my trim this way because we never have wood species specified until later in the job. I generate the estimated unit price using historical data, current raw material pricing (I use a range of our most used woods), and some forecasting (guessing).

You may need multiple takeoffs depending on sizes, and how you plan to measure, but you shouldn’t have to make a bunch of size specific assemblies. You can just add the trim item to an item group in the assembly.
If you are using an area takeoff, the assembly would need to go by the ‘measuredlinear’ so it grabs the entire perimeter. You can add a waste % multiplier in the formula.
If you are using an each takeoff where you want to enter a window size, you can have the trim item calculate based on ((width*2)+(height*2))*1.10, or whatever waste % you want to add.
