I've put together an estimate sheet that some people may find useful. It's more geared towards a GC estimate - but the principles and formula are the same for any industry. Delete rows or whatever to make it fit with your specific trade. The formulas can remain or change as you like.
I probably need to explain a few things. The grey columns at the top are the ones that you should modify - the rest are calculated. The Item Code and Description can also be changed - they are arbitrary and specific to the current job I am working on. After putting in all the information you can hide columns G through N and use it as a billing tool. To use it for billing all you need to do is enter in the TTD for the first month for each line item. The following month you will copy column S and Paste > Special > Values only into column T. This essentially zeroes out the month for the next months billing cycle. Then update the TTD column again and you're on your way.
You can also use this for a job purchase schedule or buyout schedule. After doing takeoffs and giving your best guesstimate - the sheet will give you an updated total column (Column P) - then when receiving actual bids from subcontractors you can update the Buyout / Budget (Column Q) and it will show you buyout savings or additional money that goes to profit.
One other peculiarity when using it as a billing tool - it can be used one of 2 ways. You can bill with labor and material for each line item (since it's already included there) or just update the Labor TTD on the bottom line. I do method 2 because I have a seperate cost control for labor only and it's easier for me.
Let me know if you have any questions.. there are a couple examples at the top.

You bet.. hopefully it will help others too.

That list is amazing, I was pretty proud of myself with the eight spreadsheets I had for my little project. Keeping that list running smooth is probably a job all unto itself

haha.. and that's a short list of accounts for a typical size project we do. The last project I was on we had around 500-600 cost accounts. Then add another 150 for the labor accounts.. whew. That was a full 2 day job to just update the columns with TTD information and another 2-3 days to do subcontractor billing.

hi Rich,
in your formula, concrete x3=labor, does it include excavation and backfilling or forming only

Rich

includes forming and rebar. It works out pretty close on just about all concrete I've ever done.

is there a way to estimate the excavation, and what about for a monolithe concrete slab, footings first? then the floor?

Rich

There are formulas for figuring cut and fill amounts - but after quantities it will depend on your soil type and what the going rates are in your area.

hey Rich, i still dont get it... your formula is : concrete price +3x labor... over here the price of concrete is 150$ cu/y , that would meen 450$ a cu/y for forming, it's like 4'x8' of wall, :shock: i got some rough quotes for my foundation,dont even come to 1x for forming...am i missing something? :?

450 for forming, rebar (material and labor), placing, finishing, stripping
For a 2500sf house - rough figuring 200lf of wall - foundation would cost 8400 at 70 / cy - that's worst case scenario (the 3times labor is based on an average of 70/cy). Figure your foundation at 70/cy for the labor and then go back and add the 150/cy to the labor amount.

I should also point out - that calculator can not figure your site conditions for you. It's a best guess. This estimator is by no means perfect
There is no way I could create a calculator to cover all conditions - without having an excessive amount of input values, questions, etc. If I did that I would probably sell it :)

Rich, i m not saying the formula is wrong...i m trying to understand and compare... , that's what i did...
200lf=61c/y*$150=$9150*3=$36600..correct?
$40,000 for forming+rebar ? + x$$ excavation for a 2500sf house...i can't imagine, it's like 25% of total cost, can it be???

Reread what I posted above..
61*75 = 4575 * 3 = 13725
61*150 = 9150
13725+9150=22875

ok..now i get it, so i think i got quoted good, around 2/3 mat'l cost= labor...thanks for your time Rich :D

No problem

I was looking around for that spreadsheet and only see the calculators page. :?:

It's in the first post towards the bottom - linked Estimate Sheet

On the calculator page? I don't get it. It's not on the estimating article, or the link that says estimating. Can I get a link?

Ok, I found it. Um, it could be a little more obvious :oops:

Very complete lish Rich. Thanks for the useful spreadsheat. :D

Expense for temp phone? This must be a BC list. (Before CellPhones)

That's if a jobsite trailer is setup...phone/fax/etc.

Does anyone have access to this estimator sheet and can post it again? The link here is corrupted :(

Rich

I apologize for not getting back to you Lesyk. I'll search the home computer and see if I can find it again. We've changed servers several times and that must've been one folder that didn't get brought over.

I attached the file to the first post.
