Well, that's a pretty broad question, given the numerous differences that can occur between the two, but it depends a lot of what type of "commercial work" you're talking about. Is it wood-frame or metal stud? Hollow metal door frames? ACT ceilings? MC cable on the electrical? What types of flooring? All of these are the "obvious" differences in materials and techniques that you'll need to factor into your pricing (and your subs' pricing).bergenbldr said:what do you figure differently when bidding commercial work v/s residential work.currenty job may requiere after hours work as well as dust protection of computers and workstations.what kind of warrantys are typical of small scale comm. work.
