Ok, so I accepted this job that I shouldn't have, have been paid for
work I haven't done, and as a last resort I am hoping that someone
here can help me out.
I need to produce HVAC drawings(existing as well as proposed) for a
residential-to-public-use renovation(house becomes religious center).
These drawings are to be submitted for permit approval as well as
construction. What I would like to know is what level of detail is
typically needed for this kind of drawing. Do I need to include
material specifications? I have drawn out the locations of diffusers &
ductwork, but am stumped on what to do next.
Any help would be much appreciated! I need to finish these drawings
within the next couple days or so, otherwise I will have to cancel our
agreement. If it is likely I will not be able to successfully "wing
it", I would prefer to just return payment & terminate agreement.
I agree with Don - Never Cancel a project if at all possible. I pride
myself of not knowing all the answers but I will do all that I can to find
Here are a couple of options I have done in the past:
1. Hire a local HVAC contractor like Don said - many times they will do the
design for free if the can do the build out or at a very reduced rate if
their name/logo is on the plans and they are guaranteed to at least bid on
2. There are always small, 1 man Mechanical engineering shops that are
eager to do the work and dont have the high overhead normally found. I have
found this to be extremely usefull in a pinch because they are always hungry
for work and many times their fees are minimal in perspective.
If you hire a contractor or an engineer to do the work, the liability rests
on their shoulders. Here in Phoenix where A/C is MANDATORY, this is
important. I had a case about 12 years ago when a general contractor "Value
Engineered" a mechanical system for a new upscale resturant. He said the
engineer over designed the system and he could save the owner $. Of course,
the owner liked that so they proceeded. As it turns out, during their July
opening (115 degrees that day) their star studded event was a flop. Eveyone
complained how hot it was and many of the stars that showed up, left
promplty. The contractor was sued and had to bring the entire a/c system up
to the original plans and pay for lost revenue for the 2 weeks the rest. was
shut down. The contractor had to pay about $300k all in the name of saving
the owner about $10k. Learn from this and let others do what they
specialize in, it will save you lots of headaches and $ down the road.
