anyone have any production hrs for removing aprox 200 sq. concrete sidewalk? Have a buddy who wants a concrete sidewalk removed and another one poured. Don't deal with concrete very much, but i have poured and finished concrete before for township where price doesn't matter. I don't want to underbid myself or over charge him. walk is about 40 x 5 concrete is going to run 435.00. I know all about overhead recovery so please don't preach that. once again looking for production hrs.
