Which term refers to a contractor responsible for specific tasks within a project?

The term that designates a contractor responsible for specific tasks within a project is "sub-contractor." Sub-contractors are specialized tradespeople or companies hired by the main contractor to perform a certain part of the work, such as electrical, plumbing, or HVAC installation. They are integral to managing the detailed aspects of a project because they bring expertise and skills that may not be necessary for the broader responsibilities of the main contractor.

For instance, if a construction project requires complex electrical work, the main contractor may choose to hire a sub-contractor who specializes in electrical installations to ensure the work meets safety standards and is completed efficiently. This relationship allows for a streamlined process where the main contractor can focus on project management and overall coordination while the sub-contractor handles their designated specialty.

In contrast, the main contractor manages the entire project, while a general contractor would supervise overall construction activities without getting into specific tasks. Independent contractors, while they may work on an individual project basis, do not necessarily have the same role as a sub-contractor in terms of being hired under the terms of a larger contract overseen by a main contractor.
