Subcontractors are specialized workers or companies hired by a primary contractor to complete specific tasks within a larger project. For example, in construction, a general contractor might hire a plumbing subcontractor to handle all plumbing work, ensuring that the project runs smoothly and efficiently. This allows the main contractor to focus on overall project management while relying on experts for particular jobs. Using subcontractors can save time and resources, as they often have the necessary skills and experience for their specific tasks. This collaboration helps ensure that projects are completed on schedule and meet quality standards, benefiting both the contractor and the client.
