Punch List D

I am good with renovations/remodels. Need to price addition. will have to tie into roof to raise for ceiling height. footing no problem, will only be @ 17". vinyl siding. hardwood floor. sheetrock. 3 windows, 1 door. opening to new addition through sliding glass doors. addition about 12'x18'. whats the best way to estimate this. N.C. rates.

I'll just give you a smart ass answer that I was always told to use

Figure out what the job is worth for new construction, multiply by three

I don't know if it works, but it sounds profitable

figure out all your materials, figure out your labor cost + burden, figure out your overhead, permit fees, dump fees, owners salary, 5 % misc of job cost add all it together, then add your profit onto it then take your profit divide it by your total price and you should be around 20% net profit margin ideally!!!

Well, yes and no, but you're not going to like the answers.

Yes - Do what Harmoney suggests, then divide by the square foot.



And No. - You're a remodeling contractor (that's what your profile says, anyway), so you know that remodels can run anywhere from not-too-much- per square to well over $300.00 per square, depending on what your client is asking, and the economics of scale.

This seems harder than remodels cause I always clause for unseen. This I can't.

The only "unforseens" you should have are tying into the existing structure and roof. You've got your demo on one side of the house so you can tie in, new foundation and a new structure. Price out what it would cost to "build" the new structure, 3 sides of it, and double it to cover your tie in costs, ie. matching roof and siding, and then add your O&P. Divide this total by your square foot, and don't forget to add in your S/F of siding and roofing that you have to patch in to blend with the addition, to get your $@S/F.

BTW, How goes the Racing down in Pinehurst? I used to race with a guy near Raleigh, out at Kenly and Orange County. Donald Brace? Ran Brace Towing out of Cary for a few years. What a great town. I miss that place, "A Little"! Don't miss the summer heat, though!

Drag racing and horse racing are good, other about dried up(same nol same ol). Thanks for advice

For unseens like demo add an additional 8 hours for all your guys and for blending add an additional 8 hours to what you originally thought as long as it was pratical. In other words if you think it will take 1 day write it up for 2 days. So figure out your labor and add 2 days for it also have the homeowner pay for any and all engineer or architectual drawings make sure you have a demo drawing, elevation drawing, structural drawing and also a detailed drawing where you are tiening into the house before you sign a contract. You will definately needs these drawings and maybe even an engineered stamped drawings to obtain permitting. Having these drawings will take alot of the guesswork out also it will help in material estimating and it will make you compliant with builing codes!!!

I usually go by the sq/ft charges I use for all the other odds and ends... just add up my seperate sq/ft charges and ta-da got my total. That and you come out ahead on time because of set up knock/down time of working the same job every day. just don't forget to line up the plumbing/electric subs beforehand and get a solid quote out of em... did this once and got screwed out of a couple bucks when my sparky fell through on me and I had to hire a stranger.

I just do sq/ft for my seperate charges (framing 4.00/ft, siding 175/sq, roofing 185/sq, blah, blah blah) then add so much for electric/ plumbing/hvac and permits.

Either that or do the old trusty 6x the material cost lol...
