So just to start with I do not do any of that work I just do storefronts and minor residential. But I was thinking of this today…
So you stated they want you on the job for 8 months, or a total of 34 weeks. Now if you have two guys at 8 hours a day 5 days a week for 34 weeks to meet their expectation, than that is a total of 2720 hours. 720 hours more than the 2000 your guys estimated. Now if the company is ok with you getting it done in 25 weeks which is 2000 hours for two guys at 8 hours a day 5 days a week, than you can bid it for that. But it sounds like they have had a company before and they know it will take the 34 weeks (8 months) to complete the job. Also if you are goin to work on it as well you need to cover your hours as well during that 8 month expectation. So if you bid for 2000 hours and you are there for the extra 9 weeks, than you got to figure out a way to pay your guys for the 720 extra hours that you didn’t account for.
Also price wise I have no idea where to start but I think of it this way. Insurance is going to be a lot higher for this type of project. Than since you have employees I am certain you are paying workers comp, payroll fee’s and other expenses attached to them as well. So $50-$85 an hour seems super low to me unless they are taking $8 an hour to do the job, which I doubt. I do storefronts daily and earn on a normal 20-25 hour week away from home washing windows between $55- $65 per hour. Now I am solo, so no employee expenses for me just some franchise fee’s. ( NO I AM NOT FISH!! )
So I am wondering how and why you would only want to charge such a small amount hourly and also under bid the expectation 34 week range by knocking off 9 weeks of hours? I just think after all the added expenses you will get with the big job, it seems less stressful and more profitable to just hit storefronts or market hard for residential work. I would be afraid having the lowest bid and winning the job and have everything you thought would go perfect go wrong and than your company either falls hard holding up that 3 year contract or skims by. Also with a 3 year contract make sure you put something in it to cover inflation or insurance cost or employee wage increases for the following years.
Like I said this is what I was thinking today and with no other responses to you I just wanted to chime in for ya.
I might get ripped on here for some things I said, but it is just ideas to think of.
