3.1. Material acceptance rules

The materials required for the construction of the works, whatever their origin, will be of the best quality, and will be considered accepted only when, at the unquestionable judgment of the

COR, they correspond to those designated below in terms of nature, quality, durability, suitability and application. Except for special materials, all the works must come from quarries, factories, refineries, etc., deposits. chosen exclusively by the Contractor, which cannot make any exceptions.

3.2. General rules

The items below must establish the execution rules for the various works contemplated in the

Contract, as well as the technical specifications of the materials used.

By rule of thumb, in the execution, the Contractor will have to comply with the best rules of the art as well as with the following works. For the categories of works that are not found in this

SOW, and for which no special rules have been prescribed, in particular for any work to be carried out economically, the Contractor must follow the best procedures dictated by the technique and comply with the orders that for this purpose, the COR will issue.

Works which, for any reason, immediately or subsequently prove to be badly performed, must be redone at the Contractor's expense, without the need for a formal request from the COR; the possible presence on site of an overseer of the Principal cannot be invoked by the Contractor in discharge of its liability.

For the works on the networks and for the construction of artifacts and works of art, the

Contractor, having received the delivery, referring to the project cornerstones, will first carry out the tracing of the work by affixing the stakes and modifiers for the axis, for the sections and for the works of art; at his care and expense the pickets will be maintained until completion.

3.3. Quality of materials

All the works envisaged by this SOW can be performed in perfect working order and with materials that meet the technical specifications indicated and/or referred to in this SOW.

The quality of the material used in the execution of these works must 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 Client, 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 will have to make an operating team available to the client 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.

The Contractor must promptly report any defect or anomaly found on the materials supplied directly by the Principal. .

8. To guarantee the execution of the works, maintain personal surveillance compliance in all construction sites, even if external to the places of work, on all the means used by the

Contractor, as well as in the production and material processing workshops. When this is established by the regulations, by the specifications and by the contract and when the contracting station, in warning of any regulatory or contractual requirement, signifies to the contracting party that it wants to make use of this right, the contracting station itself has the obligation to inform the station in good time Contractor of the start of processing of objects related to the works and to give it all the information it deems necessary for the exercise of supervision. He must also indicate, if requested, the establishments from which he intends to order the materials necessary for the execution of the contract.

9. The works must be carried out in a workmanlike manner and the materials to be used must be of the best quality available on the market, free from any general and special defect, meet all the other requirements indicated in the technical specifications and in the specifications as well as in the Decrees bearing the conditions mandatory general techniques.
