SUBCONTRACTORS

A subcontractor is a person or a company hired by a general contractor to perform part of the work of a construction job for a general contractor. For example, a contractor might be building a house, but might hire a firm or a person specializing in electrical engineering to install the electrical systems needed in the house. Generally the subcontractor will either relieve the main contractor of part of the building work, or will be able to perform work at lower expense or at a greater skill level than the general contractor could.

Why subcontracting ? The construction companies that execute the entire work without the subcontractor’s are rare … The non-adoption of this procedure would request a great amount of men and equipment that would be, at some moment, sub used. Facing that reality, two possibilities have emerged: - to hire and lay out - to use subcontractors
