Which type of worker typically has specialized skills in certain trades?

Subcontractors are typically individuals or companies that possess specialized skills in specific trades related to construction, such as plumbing, electrical work, roofing, and masonry. They are often hired by general contractors to complete particular portions of a construction project where expertise is needed. For example, a plumbing subcontractor would be responsible for all plumbing installations and repairs, leveraging their specialized knowledge to ensure quality and compliance with building codes.

This specialization allows subcontractors to focus on their area of expertise, which improves the overall efficiency and quality of the project. Their detailed understanding of trade-specific requirements and regulations makes them invaluable to the construction process. This contrasts with laborers, who typically perform general tasks; general contractors, who manage overall project execution rather than specific trades; and site inspectors, who review compliance and safety but do not engage in hands-on work in specialized trades.
