As far as caring how a GC keeps the site, there are delays associated with dirty jobs, difficult access to the project, dangerous working conditions, etc..., these are real considerations in making money on long term projects.
There are also two sets of numbers I give to GC's, a GC that will help us through a project and we have historically made money with or a GC with a good reputation will get a good number, a GC that historically has been difficult to work with or is known to be hard on Sub contractors get's a not so good number or no quote at all, these final numbers/decisions come from feild experience.
