A survey sponsored by Autodesk and the Associated General Contractors of America found that 80% of contractors were having difficulty finding enough qualified craft workers. It stands to reason, then, since subcontractors provide so much of the labor on construction projects, that it has become trickier for many general contractors to find enough quality subs to meet the demand. Once candidate subs have been identified, Mortenson, like many general contractors, starts off with a request for a proposal along with a qualification package that each sub must complete. The information subs turn in is independently verified. For those subs that are relatively small or disadvantaged-, woman- and minority-owned businesses, it’s not uncommon for Mortenson to break those scopes of work into smaller packages in order to make the tasks more manageable.
