A contractor is responsible for providing all of the material, labor, equipment and services necessary for the construction of a project. Contractors often hire specialized subcontractors to perform all or portions of the construction work. When using subcontractors, the general contractor is responsible for overseeing the quality of all work performed by any and all of the workers and subcontractors.

"Construction contracts should be based on site conditions as interpreted at the time of contract award. All anticipated work on foundation cleanup, preparation, and treatment should be included as specified items of the work. Contract provisions should require the contractor to submit to the construction engineer advance notice of significant shift change, to enable adequate inspection coverage of multishift operations. "[1]

"The responsibility for administering construction and supply contracts, for understanding the design and contract intent, for maintaining technical coordination between design and construction engineers, and for managing the construction staff to assure compliance with specifications should be vested in an identified engineer at the construction project. He should have the administrative and technical control of all resources necessary to accomplish safe construction of the dam. Construction personnel should understand the conditions upon which the design is based and the relationship between these conditions and the design features. When unanticipated conditions are encountered, design personnel should be involved in determining their effect.[1]
