1.02 INSPECTION OF THE WORK

A. All work performed by the Contractor shall be inspected by the Contractor and designated Owner's Project Manager and nonconforming work shall be noted and promptly corrected. The Contractor is respc;msible for the work conforming to the Contract Documents.

B. The WORK shall be conducted under the general observation of the designated Owner's Project Manager and is subject to inspection by representatives of the Owner acting on behalf of the Owner to ensure compliance with the requirements of the Contract Documents. Such inspection may include mill, plant, shop, or field inspection, as required. The Project Manager or any inspector(s) shall be permitted to access all parts of the work, including plants where materials or equipment are manufactured or fabricated.

Whenever the Contractor is ready to backfill, bury, hide, or otherwise cover any work under this Contract, the Project Manager shall be notified not less than 24 hours in advance to request inspection before beginning any such work of covering. Failure of the Contractor to notify the Project Manager at least 24 hours in advance of any such inspections shall be reasonable cause for the Project Manager to order a sufficient delay in the Contractor's schedule to allow time for such inspection, any remedial, or corrective work required, and all costs of such delays, including its impact on other portions of the work, shall be borne by the Contractor.

1.04 SAMPLING AND TESTING

A. When not otherwise specified, all sampling and testing shall be in accordance with the methods prescribed in the current standards of the ASTM, as applicable to the class and nature of the article or materials considered.

Results of such tests and analyses shall be considered along with the tests or analyses made by the· Contractor to determine compliance with the applicable specifications for the materials so tested or analyzed provided that wherever any portion of the work is discovered, as a result of such independent testing or investigation by the Engineer, which fails to meet the requirements of the Contract Documents, all costs of such independent inspection and investigation and all costs of removal, correction, reconstruction, or repair of any such work shall be borne by the Contractor.

1.05 RIGHT OF REJECTION

A. The Project Manager or designated representative, acting for the Owner, shall have the right at all times and places to reject any articles or materials to be furnished hereunder which, in any respect fail to meet the requirements of the Contract Documents, regardless of whether the defects in such articles or materials are detected at the point of manufacture or after completion of the work at the site.
