Clean Site Clean Work.

You can usually tell the quality of work being performed by a general contractor by the cleanliness of the site.  I have never seen good work on a messy site, you can find bad work on a clean site but it is guaranteed on a dirty site.

Piles of garbage make it hard to work.  Things lying around make for tripping hazards.  Tools and product get damaged and lost.  Below are pictures from a site I deal with.  The General Contractor or Construction Manager low lid the job and spend all day trying to find change orders.  The work performed is shoddy, and there is constant damage.

Garbage brings mice and rats.  This site has them frolicking on it!
