As a new corporation with one employee (me) I have yet to take on a new construction job myself. At this time my income comes from service and equipment replacements which usually include minor duct changes such as plenums, return boots and transitions. My question is what is the best way one can bid a duct job? I know answers may vary, but whatever information you may provide would certainly help. I know how to bid equipment and parts for service however When it comes to duct I am greeeen. I never saw how my old boss would figure it out. Thank you for your guidence!
