Most contractors that actually employ mechanics (like carpenters) should have no problem erecting a quality storage building package...
the process is much easier than constructing a building from dimensional lumber...there is very little cutting involved...it is so simple...
for someone that has never done it...there is hardly any learning cure at all...anyone that can read a plan and use a tape measure and a few wrenches & a screw gun would have no problem...A quality package has explicit drawings and details and all the parts are labled...the average "carpenter's helper" would have no problem...
So, lets say that we have Contractor A who is looking to expand into the storage building buisness.
He has a crew of 10 people who fall into the jack of all trades category. They do everything from pole bars, to replacing barn foundations, to re-roofing houses, but they have never done a storage unit building and rarely deal with rollup doors, they generally do sliding doors for barns and shops. Also worth noting, is that Contractor A is equipped to deal with a little of everything and had tools to handle all of the types of jobs they do.
Contractor A calls Contractor B up. Contractor B ONLY does storage buildings. He always buys from the same factory, in fact he spends $300,000+ a year there and due to this, he gets a 15% discount over what someone else would get. His guys spend 40-60 hours a week putting up storage units. He has an advance crew of 3 guys who come in a few weeks before to do the foundation and then he has a 10 man crew that comes in.
This crew has
A. 3 guys who do the framing with the steel trusses
B. 3 guys who install the metal siding/roof pieces
C. 2 guys who do the trim
D. 2 guys who just do the doors
Contractor B has the tools so that they are each equipped to do their job without having to wait for someone else to get done with a tool, because this is all that they do.
Can you tell me that a crew of 10 guys who do a little of everything will not be 10-20% slower than a crew that ONLY does these buildings even if the crew is composed of guys who know how to think and work?
In addition, while his guys are working on his building, they are not out making him money.
Due to this, it is entirely possible that Contractor B could do the same job with the same materials for 10-20% less than Contractor A's own crew could. That is the beauty of specialization.
