The quality of the material used in the execution of these works shall meet, when not otherwise specified by Contractor rules or regulations, the requisites required by the laws in force and by the official standards of good construction techniques.

The Government during construction and at any time, may take material samples from the manufactured articles used to verify their perfect correspondence with the approved types.

In this case, the Contractor shall have to make an operating team available to the Government to carry out the activities necessary for the execution of these checks, carried out with the help of a specific specialized Contractor. These charges will be charged to the Contractor, including any demolition and reconstruction of the works found to be non-compliant.

He shall keep the packing slips/supply of materials in absolute order in special catalogues/binders prepared for this purpose.

6. It is absolutely forbidden to access the site for Contractor personnel who, where requested, refuse to submit to personal checks or checks on things in tow.

The Contractor shall justify, with the presentation of suitable documents, the actual origin of the materials, and lend himself to subjecting them to all the tests that the project manager deems appropriate to ascertain their quality and resistance. The materials cannot be used if they have not been previously accepted by the construction manager who has the right to refuse those he does not recognize as suitable for the goodwill of the works. The rejected materials shall be removed from the construction sites within the term established by the COR and at a convenient distance; failing the Contractor to comply with the relevant provision, the COR has the right to do so directly, charging the Contractor the related expense, which will be deducted from the first advance certificate. Acceptance does not affect the right of the contracting station to refuse, at any time until testing, the works performed with materials that do not comply with the contractual conditions, materials to proceed, pursuant to current laws, in the case of construction defects. When the Contractor presents concrete for and the relative samples, the contracting station may examine proposals to replace the quality of the materials and their origin, if prescribed, however reserving the full right to accept and reject said proposals. If, even without opposition from the site manager, the Contractor has on his own initiative used materials of a better prescribed excess weight and size, or of a more accurate quality or mastery, he is not entitled to any price increase, whatever the the advantages that can derive from the contracting station; and in this case the accreditation of the

Contractor is done as if the materials found the weight and dimensions, the qualities and the mastery established in the contract. Conversely, objects or materials of weight, characteristics and/if smaller than those prescribed, or of lower quality or less accurate workmanship are used, they will be counted by reducing in proportion to the lower weight, smaller dimensions and different quality and processing the corresponding prices.
