At the completion of the cleaning operation, the contractor's supervisor shall perform a <br />complete visual inspection of the work area to ensure that the work area is dust-free <br />and fiber-free. If the supervisor believes he is ready for a final project decontamination <br />inspection, he shall notify the designer. <br /> <br />G.
