Bren,

Many EC's try to use a sq ft method, for bidding production work, and if the job has been estimated using take-off sheets, from a set of plans, and all material costs are known, along with a list of actuals for labor, then they stand a pretty good chance of developing a job for profit.

After all the cost are known, add your profit, then take that figure and develop a sq ft price, if that price is to high for the GC, then maybe you are the winner, because most GC's we did production work for never paid anyway.
