What are the roles of the architect, general contractor and the subcontractor?

The architect or designer is responsible for creating a plan that meets the needs and constraints of the homeowner. The general contractor is responsible for implementing the plan. He oversees all work to complete the project. He must work closely with the homeowner and the architect. The contractor generally has employees and that work for him on a daily basis, but then for some areas of the job will hire subcontractors. Subcontractors are independent contractors who are paid just for the work they perform at the time they perform it. They carry their own insurance and are not employed by the contractor.  more
