Define "subcontracting" in construction.

Subcontracting in construction refers to the practice of outsourcing specific tasks or work to other individuals or companies, known as subcontractors, who are specialized in those particular areas. This practice allows the primary contractor to manage a project more effectively by leveraging the expertise of others for certain components that may require specialized skills, tools, or knowledge.

By subcontracting, the primary contractor can focus on overall project management while ensuring that specialized tasks, such as electrical, plumbing, or masonry work, are performed by skilled tradespeople. This approach not only improves the quality of work but also aids in meeting timelines and budget constraints.

The other definitions do not capture the essence of subcontracting: hiring additional supervisors pertains more to management rather than task execution, signing agreements without binding commitments does not relate to the work being done, and managing multiple projects simultaneously is about capacity rather than task specialization. Therefore, the definition that best aligns with the practice of subcontracting is outsourcing tasks to other individuals or companies to complete specific work on a construction project.
