In the event of a temporary association of companies, the above applies to the agent Contractor or Contractor designated as group leader. In the event that the drafting of the safety and coordination plan is not envisaged, the

Contractor must draw up and deliver its own replacement safety plan to the COR within the terms established by the Rule. It should be noted that the amount of the charges deriving from the implementation of the provisions of the aforementioned construction site safety documents, expressly indicated in the specifications, are understood to be offset and included in the unit and/or bulk prices of the various items of the estimate. Having established that the percentage safety incidence of the safety charges of each individual estimate item is conventionally assumed to be equal to the ratio between the global work costs and the gross amount of the safety charges, the portion of the amount not to be subject to a discount will be equal to product of the aforementioned incidence by the gross amount booked.

4. The Contractor is obliged to adapt the working hours to the User's needs, with the obligation to obtain the information in advance.

5. The Contractor, through its manager, will have to keep a register updated on the construction site, to be shown for inspection by the Project Manager himself or someone on his behalf, such as in the work itself or to be noted on a daily basis materials and inflows on site to be used in the works, those used in the execution of the works themselves and those removed from the site, with the resultant of the materials stored there. He must 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 contracting station declines any responsibility if the refusal referred to in this paragraph causes delays, hindrances or even the impossibility of executing the contract.

In any case, the Contractor remains liable for damages caused by the inexperience, negligence or bad faith of the personnel themselves.

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. When it comes to national products, the Contractor is free to procure materials where he deems the best, provided that they have requirements where prescribed by the contract, unless in these general conditions, in the special chapter or in the price tariff, special requirements are prescribed on origins some materials. The Contractor must 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 must be removed from the construction sites within the term established by the construction manager and at a convenient distance; failing the Contractor to comply with the relevant provision, the site manager 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 art. 18 of DM 145/2000, 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.

• The chemical analysis, which for weldable products, must satisfy the composition limits recommended by UNI 5132

• The statistical processing required by the attachments of the Ministerial Decree of 14.01.2018

The COR may request to take samples of materials for further tests.

• Marking

The Contractor shall mark and document all materials to ensure they are used as specified.

• Location of Markings

The markings must be positioned so as not to be hidden by other materials after installation.

• Stamping

If the steel is to be sandblasted, acid-treated, sprayed, or galvanized, it must be marked with low-pressure marking. Marks must be of adequate depth to avoid deletion. Sandblasting, where necessary, must be done according to the American standards.

• Length

Members having both ends prepared for compressive contact, such as struts or columns, should not deviate from the intended length by more than 1mm. Elements that do not have the ends prepared for compression contacts, and which must be connected to other metal parts of the structure, must not deviate from the pre-established length by more than 2mm if the total length is equal to or less than 10m, and 4mm for elements longer than 10m.

• Compression Joints

The gap between joints whose performance, when assembled during manufacture, depends on compressive contact, must not exceed 0.75 mm and must be less than 0.25 mm over 50% of the contact section length.

• Storage and Handling on Site

Steel structures will be placed in a separate storage area from other site materials. This area will be kept clean. The Contractor will ensure that there are no earthy residues or other impurities/slag on the surface of the profiles before assembly. If there is dirt, it must be removed by brushing. All steel structural elements brought to the construction site and stored before installation must be adequately protected and supported to be lifted off the ground. Part markings must be visible when parts are stored. The Contractor must use the utmost care in packing the material and in handling and transporting the metal structures to avoid any damage to the structures themselves and to the protective layers.

• Pre-assembly on Site

All pre-assembly of the structures will be carried out on benches raised off the ground, suitably prepared by the Contractor. The pre-assembly areas, unless otherwise agreed with the COR, must be outside the perimeter of the finished building. Upon delivery of the works, the COR will indicate to the Contractor the areas envisaged for pre-assembly. The pre-assemblies must be carried out according to the assembly program, and all pre-assembled material must be stored in appropriately prepared buffer areas. All material stored in the buffer areas shall be sequenced according to the installation schedule. If it is not possible to provide site areas sufficient to allow the pre-assembly of the structures on site, this operation must be performed by the Contractor at its workshops or another place agreed upon and accessible to the Works

Manager. The material must arrive on site already sequenced according to the assembly schedule.

• On-site Assembly

Before drawing up the tender offer, the Steel Works Contractor is required to carry out a site visit to ascertain the operating conditions associated with assembly. On this occasion, a "Report of the Visit" must be drawn up. During the preliminary site visit, the following areas will be identified:

• Storage area

• Pre-assembly area

• Assembly area (lift)

All in relation to effective general operations. The Contractor is required to check the tracing of the anchors to the reinforced concrete structures before starting the assembly phase. Under no circumstances will claims relating to tracking errors be accepted by the executor of the civil works.

• Cutting

Steel must be cut with an automatic or semi-automatic system. Manual or flame cutting will be used only when the use of automatic or semi-automatic machinery is not possible, and only with the approval of the

COR. The use of hot device cutting equipment is not permitted without prior approval. If flame cuts are made, the edges of all the cut plates must be smoothed to remove scale, marks, deposits, irregularities, and excessive hardening. Burrs, sharp edges, and irregular edges must also be removed by grinding.

• Bearing Contacts for Joints Subjected to Compression

Joints subjected to compression will have contact surfaces prepared to obtain an adequate joint plane. It will be possible to use filing, cutting, or other equivalent systems approved by the COR. The surfaces intended for contact joints must be at right angles to the nominal axis of the element itself. Different angles will be accepted only if indicated and annotated in the carpentry drawings. It is not necessary to carry out any additional preparation on surfaces intended to be incorporated in mortar beds, such as foundation plates, or those of attachment of metal structures to concrete structures.

• Stiffeners

The stiffener gussets will be cut and sanded to ensure precise contact along the edges of the flanges.

• Straightening

No straightening of the material must be carried out that could cause alterations of its physical or chemical characteristics and consequently non-compliance with the requirements specified for the material at the time of supply. Before starting work, the Contractor must provide the COR for approval and include in its

Method Statement the procedures it intends to adopt for any straightening interventions on structural elements.

• Heating

No heating of the material must be carried out that could cause an alteration of its characteristics and consequently non-compliance with the requirements specified for the material at the time of supply.

• Temporary Connections

After their use, the Contractor must remove any temporary connections that may have been necessary to implement their method of manufacture or implementation. The removal of any temporary element must take place in compliance with the relevant regulations and with a procedure agreed upon and approved by the COR.

• Assembly

Whatever the assembly sequences, the Contractor must take into account the static behavior of the structure in the partial configurations and the stresses produced during the lifting phase by drawing up a specific calculation report. It will also be necessary to define the type of substrate suitable both for the passage of vehicles and for the correct pre-assembly of the structures.

• Alignment of Structures

All structural parts will be aligned as soon as possible after their assembly. Permanent connections between the various members will not be made until the structure has been sufficiently aligned, leveled, plumbed, and temporarily connected. The Contractor shall ensure that the various components do not go out of square when setting up or aligning the rest of the structure. Due consideration should be given to the effects of temperature on the structure and measuring instruments when taking measurements for layout, siting, and construction, and for all subsequent dimensional checks.

• Pillar Leveling

The leveling and plumbing of the pillars will be done using flat wedge-shaped steel plates of adequate size, strength, and stiffness. Where leveling plates are left in place for later incorporation into mortar, they should be positioned so that they are completely enclosed and covered by the casting.

• Theoretical Design Counter-arrows

The geometry shown in the drawings of the Executive Project corresponds to the undeformed structure and net of preforming; the Construction design will have to consider the appropriate strategies for a possible pre-camber.

• Counter-arrows for the Settlement of the Joints

A further and adequate preforming may be envisaged to cope with irreversible settlements, taking into consideration the cumulative settlement of the joints present in the roofing structure.

• Baseplate Bolts in Sleeves

The anchor bolts of the base plates must be placed at a suitable distance from the surfaces that laterally limit the reinforced concrete structure to which they are anchored. The anchorage length must comply with the provisions of the DM 14.01.2018. The plan position of the base bolts positioned in sleeves, which will eventually be concreted in, must not deviate from the position specified on the drawings by more than 5 mm.

• Welded Joints

Welds and steels for welded structures must comply with the recommendations contained in UNI 5132.

Welds must be done under the direction of welder technicians who have appropriate qualifications and who have procedure certification according to UNI 4634.

• Welding Procedure

The welding procedures must comply with the recommendations of UNI 5132. For the execution of the welded joints on site and/or at the foot of the work, an approach of the parts must be guaranteed within the tolerances allowed for each type of welding. The necessary supports of the filler material must therefore be provided in accordance with the preparation of the flaps. All necessary precautions must be taken for perfect alignment of the parts to be welded. As a general rule, welds should not be smoothed unless explicitly indicated on the drawings. Welding procedures and fabrication sequences should be such as to minimize distortion.

• Temporary Welds and Temporary Connections

Temporary welds and those relating to temporary joints, necessary for manufacturing and/or installation, must comply with the aforementioned regulations and must be removed so as not to damage the permanent works. The removal method must be submitted for the approval of the COR.

• Butt Welds

Where possible, backplates will be used to ensure full thickness/fill of the groove at the ends. These plates must meet the following requirements:

✓ The mechanical and physical characteristics for the plates must be identical to those of the material to be welded.

✓ The plates must be prepared in the same way as the parts to be joined.

✓ After completion of the weld, the plates must be removed by cutting. The surfaces to which they were attached should be chamfered, ground, and inspected for cracks.

• Welds of Pins or Connectors

Where foreseen, the rotation or sliding pins must be installed according to the manufacturer's prescriptions both for the materials and for the accessory procedures and devices.

• Welding Test

Before starting work, the Contractor must conduct a series of welding tests on pins/connectors to verify the adequacy of the welding system and the proposed equipment. The tests must be carried out using the same material and the procedures foreseen for the works. At least ten percent of the connectors must be tested in trials. In the hypothesis of in situ welding of the connectors, at the beginning of each shift, at least two welding tests must be carried out for each welder.

• Slag Removal

The slag will be removed with light hammering, metal brushes, or other methods that do not deform the weld surface.

• Holes for Bolted Connections

All holes will be punched and reamed unless otherwise agreed with the COR. Unless otherwise indicated on the drawings, the holes for normal bolts must have a diameter equal to that of the bolt, increased by 1.0 mm up to diameter 20 mm, and by 1.5 mm for diameters greater than 20 mm, except for foundation plates where a slightly larger tolerance is acceptable. In the event that the holes move out of alignment between two flanges, it is not permissible to enlarge the holes or distort the metal to achieve alignment. For bolts and vent holes in hollow sections, the holes shall be sealed to prevent moisture ingress. If the methodologies to be used are not specified in the project documents, they will be defined by the Contractor who will illustrate them in their method declaration.

• Preparation of the Elements to be Bolted

For all bolted assemblies, the degree of resistance of the bolt-nut-washer combination must comply with the provisions or recommendations in the relevant Standards.

• Condition of the Bolts

The bolt assembly immediately prior to installation must be in such a condition that the nut rotates freely on the bolt.

• Washers

Each bolted connection must contain at least one washer placed under the part being rotated.

• Variable Thickness Washers

These washers shall be used under bolt heads or nuts that rest on surfaces inclined 3 or more degrees from the plane at right angles to the bolt axis.

• Locking Bolts

Nuts used in joints subject to vibration or reverse stress will be suitably locked. If the methodologies to be used are not specified in the project documents, they will be defined by the Contractor, who will illustrate them in their method declaration.

• Length Limits

The length of the bolt must be such that at least one thread is visible above the nut after pulling, and at least one thread other than the final thread is free between the nut and the non-threaded part of the bolt.

• Bolt Pull

The tightening torques will comply with the recommendations contained in Eurocode 3. The tightening must never be pushed beyond the nominal limit to avoid compromising the capacity of the joint. The tightening torque tolerance is 10%.

• Connections that Allow Movement - Slots

If slotted holes are indicated on the drawings to allow movement, the joint must be assembled in such a way as to allow the desired or prescribed movement. Slotted connections will be made using the following method:

• The slotted hole must be of a larger diameter than the non-slotted one.

• A bolt of the large head type must be used, with a spring washer under the head, which rests on the contact surface of the non-slotted part.

• A flat washer must be placed under the nut, and this must be tightened on the non-slotted side.

The Contractor is strictly prohibited from making slots in the connections where they are not specifically prescribed by the project. In the event that this prohibition is not respected, the DL will order the immediate replacement of the pieces in question.

• Chemical Connectors

Where specified in the project documents, the use of connectors that use chemical resins is permitted, provided that the specifications and methods required by the manufacturer are scrupulously followed. The choice of the appropriate type of chemical connector, if not indicated in the project documents, will be made by the Contractor based on the loads and functions that the connector must perform, subject to approval by the Works Manager.

• Anchor Bolts

All base bolts should be securely in place during installation. During all stages of construction, all bolts, threads, and nuts shall be protected to prevent damage, corrosion, and contamination. The cavities formed to house the base bolts must be kept free and clean of foreign bodies.

• Corrosion Protection - Galvanizing

For the metal members (steel), a protection system for galvanizing by hot immersion is foreseen according to UNI 5744/66. The protection systems must be preceded by the preparation of the surfaces, consisting of:

• Degreasing

• Washing

• Pickling

• Washing

• Flushing

• Desiccation

Furthermore, the preparation must include:

• Preparation of the metal support with sandblasting cleaning to Sa21/2 degree according to SSPC-

SP10/63; procedure to be carried out exclusively with initial state of steel A, B, C, D according to photographic standard SIS 055900/67. Reach proficiency level A21/2, B21/2, C21/2, D21/2. If the metal support does not meet the above photographic standard, it must be brought to that state before the subsequent preparation.

• Preparation of the metal support with Sa3 grade white metal sandblasting cleaning according to

SSPC-SP5/63; procedure to be carried out exclusively with initial state of steel A, B, C, D according to photographic standard SIS 055900/67.
