Specs and Drawings
Dont know if this is the right forum to ask. I am wondering how is the best way to learn how to read the drawings of the buildings that we do the work on? Is it just practice, or is there some kind of class that I could take to learn more?
Thanks in advance
Youtube has many videos to help you start out just do a search for reading blueprints.
Yea, Blue Prints, drawings? Dont even know the correct term!! LOL!!

My boss said it just takes time, and alot of practice, so I would like to get a start on learning, but just dont know where to start.
you need to find a drafting class, they will teach you how to interpret blueprints
figure out the legend or schedule of the prints, life will get easier
It`s better to be silent and thought the fool; than speak and remove all doubt.
Had to take a basic blue print reading class back in trade school. Doubt I could manipulate my way through them anymore. Four credit hrs if I recall correctly.
May be able to find something offered at a local community college. Good class, just wish I'd have used it fresh out of the course. Might have stuck better.

I'd ask the boss for prints from previous jobs and start there.

The specs, details and section views are where you will lose your ass if you aren't paying attention.
On the bigger jobs, you gotta watch out for stuff like the sprinkler main in the same space as your ductwork... or the sprinkler heads in the same space as your diffusers.
And the can lights. Oooh, the can lights. Tall electrical fixtures under or near the ductwork isn't fun, especially when the project is moving forward on construction drawings.
And if the builder isn't paying for mechanical overlays... guess who gets to figure it out.
Although I haven't had the opportunity to start bidding jobs, my boss exposed me to shop drawings for submission (after bidding). I don't know if your company does shop drawings, but that would also be great exposure opportunity, because you have to understand the whole system, which will tell you what your company must provide (after reading the mechanical spec). I found that sometimes there are discrepancies between the bid and the actual shop drawings, but more or less they are within reason. This is just what I thought - when I started, I thought i knew how to read them, but found out quickly that all I saw were a bunch of lines for the first few days. From cross referencing between the legend and the layout, I got the hang of it fairly quickly.

Very, very accurate. You must know the specification book backwards and foreward. There are few things more satisifying than having an engineer reading through his own spec to find a "gotcha" when you know it's not there. Had an engineer from a huge firm tell me the ductwork in a food court had to be stainless, because the spec said any duct exhausting humid air had to be stainless. Argued the return was exhaust. I pointed out that the food court used all paper products. His reasoning : "they make coffee don't they". I asked him to pull out a psych chart and find out how many pots of coffee would have to be on to raise the RH 1%?
