5.1. 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 Company, which cannot make any exceptions, if during the course of the cultivation of the quarries, or operation of the factories, establishments, refineries, etc. the materials no longer met the prescribed requirements, or were missing and it was therefore obliged to resort to other quarries, in different locations, or of different origins, it being understood that, even in such cases, the stability unit prices in the list will remain unchanged and the sums for lump sum fees, as well as all that is observed to the quality and individual materials.

5.2. General rules

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

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

As a general rule in the execution, the Company 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 Company must follow the best procedures dictated by the technique and comply with the orders that for this purpose, the Works Management will issue.

Works which, for any reason, immediately or subsequently prove to be badly performed, must be redone at the Company's expense, without the need for a formal request from the Works

Management; 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

Company, 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.

5.3. 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 and in the annexed documents.

The quality of the material used in the execution of these works must meet, when not otherwise specified by Company 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 Company 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 Company. 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.

5.4. Equivalent Materials

The Contractor shall verify and ensure that all the materials supplied are new and without defects and that their use and/or installation is carried out using the best techniques and fully respecting the instructions supplied by the manufacturers.

Special parts shall be manufactured solely by workshops that are highly qualified in that specific sector.

The makes indicated in this SOW (Scope of Work) are intended as a point of reference and therefore, the words or approved equivalent are implicit.

Therefore, the makes and products listed are deemed equivalent to each other. Different selections implemented by the Contractor shall be approved in advance by the COR, after submission of samples and technical cards.

5.5. Work for Cable Conduict

1) Pipe handling

The provisions indicated by the producers of the various types of pipes supplied in the specific instructions for use, which must necessarily acCompany the supply of the material, must be scrupulously followed.

In addition to this, the Contractor will have to do the following:

a) Loading, transport and unloading

Loading, transport by any means, unloading and all maneuvers in general must be carried out with the greatest possible care, using means according to the type and diameter of the pipes and adopting all the necessary precautions in order to avoid breakage, cracks injuries or damage in general to the materials constituting the pipes themselves and their coating, if any.

Therefore, protruding and protruding bodies, excessive sliding, contact with which deterioration or deformation of the pipes can still occur. In the construction site one must prepare what is necessary (one will have to prepare to install the pipes, the special pieces and the accessories to be installed).

b) Stacking and storage

The stacking must be carried out by arranging the pipes in stacks in pitches suitably located along the route on a flat and stable area, sheltered from the sun's rays in the case of pipes subject to deformation or deterioration caused by significant thermal variations.

The base of the stacks must rest on suitably spaced tables or on a suitable support bed.

The height will be contained within the limits suitable for the materials and diameters, to avoid deformations in the base pipes and to allow easy sampling.

Stacked pipes can be blocked with wedges to avoid sudden rolling; protective measures, in any case, must be adopted to prevent the heads of the pipes from being damaged in any way.

The ends of the pipes intended for the conveyance of water for human consumption must be protected with suitable caps, in order to avoid dirtying the internal surfaces. For deformable pipes, the ends will be reinforced with provisional crosspieces. The joints, gaskets, bolts and materials in general the rays deposited, if perishable, be rays deposited, until the time of their use, in closed spaces inside containers protected from the sun or from heat sources from with oils or fats and not subjected to loads.

2) Excavation for the pipeline
