0 a person who undertakes work for a contractor and is therefore not directly employed by the person who wants such work done -- underentreprenør
The building contractor has employed several subcontractors to build the block of flats.
We interviewed 2 general contractors and 12 subcontractors that self-per form construction work on drywall, structural concrete, mechanical ductwork, process piping, and electrical systems.
Under the system, the entrepreneur supplied raw materials to subcontractors, who performed the work at home using their own machines and equipment.
One subcontractor in building construction stated that he was paid on a monthly basis, and only at a given rate per square metre completed.
Because their activities are interdependent with other subcontractors' activities, subcontractors have to consult with other subcontractors when rescheduling their activities.
Therefore, there is a need for a methodology to handle subcontractors' resource-driven schedule changes.
This resource histogram implies that some subcontractors' schedules differ from their original ones.
Changes are likely to cause schedule conflicts among subcontractors because any move affects the activities of other subcontractors in tightly coupled construction project schedules.
Traditional centralized coordination techniques used by general contractors become insufficient as subcontractors per form most work and provide their own resources.
