Manufacturing Ductworks

In your project, you have a set of HVAC Drawings as Issued For Construction, now, as you are elected to supervise for the project, what is the first thing to do in order to install the ductwork accurately from the given IFC Drawings to the specified location? Can anyone specify which standard have to follow prior to manufacturing of ductworks and could you differentiate the two leading standards?

As project supervisor, to install correctly and systematically the ductworks, I will make first the ducting cutting lists. This is a list of duct portions such as straight ducts (1.2 m nominal length), number of spools (straight ducts with less than 1.2 m nominal length), number of duct fittings (elbows, wyes, offsets, transitions, collars, volume dampers, etc.). And each of these duct portions has designated tagging reflected on the ducting layout to determine easily where the particular portion belongs.

What I usually use as references in ductworks design/fabrication are the following: CARRIER Handbook Part 2 Chapter 2 & 3; SMACNA HVAC Duct Construction and SMACNA HVAC System Duct Design; and the ASHRAE Fundamentals Handbook Duct Design Chapter.
