Answer:
The statement is: False.
Explanation:
Contractors are independent parties who are hired to perform a determined work. They handled their operations as small companies managing their own personnel and operations within the physical location of another company or where the hiring company requests it.
Among the duties of contractors, if they are dedicated to the construction industry, they can decide the process they will follow for mixing the concrete and the materials necessary for such purpose unless the hiring company establishes something different. In case of failure, they should find ways to replace the damaged items or structures but that does not imply the contractor loses its independent contractor status.
