Hi all,
So now that I am in the "final stages" of my garage build, I was wondering how everyone calculates DIY vs. hiring someone.
For example, I just had 80 tons of gravel delivered for around my garage. A buddy came over with his tractor and box blade and we spread it and I used my plate compactor throughout the process. Each load was 20 tons and cost me on average $500 with $100 of that being delivery charge.
Right off the bat, I thought doing all the spreading and such saved me money but upon reflection I started to wonder.....
For example, I paid about $400 for delivery charges (100 per load) and paid "retail" for the crusher run and #57 stone. If I paid someone to do it and they had their own truck, the delivery is not an "upfront" cost for them. Also, what is their discount on the stone as a contractor? Could it have been 20%?
Doing some simple math, $2000 - $400 delivery = $1600 for the stone. 20% discount on that is $1280.
So that is $720 that is either absorbed by the contractor or part of the "profit" (I realize there are many expenses of running the business that exist but trying to keep this higher level for estimating DIY purposes).
I also realize that having a contractor(s) estimate on every job is not realistic or fair to them if you have no intention of hiring the work out, so for the sake of high level estimating what do you all do?
Do you look at the retail price of materials and figure a 10 or 20% contractor discount and then just estimate if someone would realistically do the job for the material savings?
Going back to my example, I don't believe someone would bring a truck/trailer with the tractor(and implements to spread) and another truck (quad axle dump in my case) for 4 loads throughout the day for $720 (if they got 20% discount on material). Maybe I am wrong?
Just curious on what other factors you take into consideration - special tools needed, permits, expert knowledge, risk factor for having to "redo", etc.
