Practical, direct, no-nonsense. Wish I'd had this when I was starting out. . .

It is a very good book. . .

SF & LF estimating

Square foot (SF) and linear foot (LF) are units of measure: total SF of siding or plywood or total LF of copper pipe or gutter and downspout, for example. SF/LF pricing is used in stick and unit estimating, but it can also be used as a stand alone method for certain types of work—simple decks, blacktopping a driveway, or replacing asphalt shingles, for example—and it can be useful when providing preliminary pricing during the early stages of a project’s development. But SF/LF pricing fails quickly—and should not be used—if you don’t have reliable cost data, if you are unfamiliar with the construction method, or if the site or the work is nonstandard. Other downsides to SF/LF pricing are that, if something must be added or removed from the estimate, there are few details available to adjust, and, because you are not breaking the project into it smaller parts, it is easier to miss nonstandard items.
