if you are working with a GC does that mean you have a contract with them? if you do why are you checking on their pricing now? just trying to make sure I understand what the purpose is.
anyone can post pricing on this website and it may be accurate for "their" area. labor costs vary in different parts of the country. I can get labor a lot cheaper back in Florida than I can in Massachusetts. The price you have does not necessarily mean you're on the high end, unless you have other bids from local builders. Cannot compare apples to oranges, and that is what you are doing when you compare labor costs in one part of the country with another.
did you talk with other builders before selecting yours? did you get references and call them? did you ask them if they would hire the builder for their next project? Check out http://www.nahb.org/generic.aspx?sec...ontentID=89767
for questions to ask, and additional information available to assist in selecting a builder for your project.
a far as cheap illegal labor ...... you get what you pay for. cheap illegal labor typically do not know how to build properly, is that what you want?
now shady fly-by-night "builders" (if you want to call them that) may use cheap illegal labor, build substandard, and take your money and run. Sometimes people only want "cheap, cheap, cheap", then complaint when they get what they pay for.
a legitimate building employs knowledgeable personnel, has a license, is bonded and has insurance (should see what they pay), must meet not only the building code but EPA and OSHA requirements. They have overhead as any business does and if they do not make a profit then they go out of business. What you want to look for is quality and value for your dollar, not merely how many dollars you will spend.
A fly-by-nighter has none of those requirement, so they can charge less (of course its not the same quality of workmanship).
If you do not have a contract with your current GC then check with family and friends and get references of builders they recommend. let you fingers do the walking in the yellow pages and follow the guidelines of the NAHB is selecting a builder. This is how you get quality and value.
