Supply and installation of a waterproofing or capillary moisture protection system for the foundation, where required by site conditions.

Supply and installation of the flagpole-to-foundation connection system (welded base plate, bolted flange, or embedded anchor system), determined based on the flagpole type approved by the COR, including anchor verification for: tension and shear forces at the base, pull-out and punching shear checks, anchor bolt specifications (diameter, grade, embedment length, torque requirements).

Corrosion protection treatment of all exposed metal components by hot-dip galvanizing or an equivalent corrosion protection system, appropriate for the environmental conditions at the site.

Collection of at least one concrete cube sample during the pour for compression strength testing at an accredited laboratory, including transport and laboratory test report.

Supply and installation of flexible corrugated conduit for outdoor use, minimum size 75mm, in compliance with CEI standards, complete with a steel draw wire or other suitable pulling wire for subsequent cable installation.

Trench backfill using suitable material (preferably sand or selected granular mix in the section in direct contact with the conduits), placed and compacted in layers.

Reinstatement of all surfaces affected by excavation works (pavements, curbs, green areas) to a finish equal to or better than the existing condition.

Connection to the existing electrical panel located on the inner side of the boundary wall along Via Giacchino Rossini, including all necessary connection works.

Supply and installation of a dedicated circuit breaker for the flag lighting system, inside the existing panel or in an extension thereof, sized in accordance with the installed power and applicable regulations.

Supply and installation of a twilight switch (photocell) for automatic control of the switching on and off of the floodlights, including all electrical connections, calibration, and functional testing.

Supply and installation of CE marked electrical cables of adequate cross-section, laid inside the prepared conduits, with proper identification and terminations.

Supply and installation of 3 in-ground or floor-mounted floodlights with a minimum protection rating of IP67, suitable for outdoor use and architectural lighting of the flagpole and flag, positioned at the cardinal points (North, South, and East) along the perimeter of the travertine slab (diameter 1.50 m); model, power, colour temperature, light beam, external finish, and installation method to be submitted to the COR for approval prior to purchase and installation.

Supply and installation of 3 inspection handholes with minimum internal dimensions of 600 mm, with characteristics and load capacity suitable for pedestrian use, positioned as follows: one near the flag area (serving the base and the floodlights), one approximately halfway along the cable route, and one near the base of the existing electrical panel; handholes shall be equipped with anti-slip covers with appropriate load class, positioned and levelled so as to integrate with the paving without creating obstacles or hazards for pedestrians.

Supply and installation of reinforced concrete screed (characteristic compressive strength Rck 300 kg/cm² / C25/30), thickness 15cm, reinforced with electro-welded mesh Ø8/200×200 mm, to be constructed beneath brick floor tiles and beneath travertine slabs around the flagpole area. Excavation included.

Completion of paving on top of the foundation with brick and clay paver strips, in line with the design and geometry of the existing pedestrian path, including all cuts, adjustments, and joint finishing.

Supply and installation of the circular travertine slab around the base of the flagpole, with particular attention to alignment with the pole axis and regular joints relative to the surrounding paving, including sealing.

Arrangement of adjacent areas (flowerbeds, borders, curbs) to give the entire area a neat, coherent, and dignified appearance.

Final cleaning of the area with removal of construction debris, packaging, and any other unnecessary materials, and handover of the works in a condition ready for immediate use.

Supply of the flagpole in hot-dip galvanized steel or structural aluminium alloy, rising 12.5 m above finished ground level, in compliance with all applicable current construction standards and specific standards governing flagpole design and installation; including all construction details (cross-sections, wall thicknesses, joint details, and segment configurations where applicable), a full description of the operating systems (winch or cleat mechanism, internal blocks and pulleys, locking devices), and written instructions for both routine and extraordinary maintenance of the flagpole and all its components.

Supply and installation of the internal halyard assembly, whereby the rope or cable runs entirely inside the pole shaft, including: internal rope/cable running through the full height of the pole to operate the flag raising and lowering mechanism; a lockable access door or winch box installed near the base of the pole; an internal pulley system at the top of the pole, fully protected from weather exposure; a counterweight and retainer ring to keep the flag close to the pole shaft and ensure smooth and controlled movement during operation.

Supply of the flagpole structural calculation report, signed and stamped by a licensed engineer, demonstrating the full adequacy of the proposed flagpole for the required installation conditions, with reference to: flagpole height (12.5 m), flag dimensions and weight, wind exposure and local environmental conditions at the installation site, wind loads in accordance with applicable standards, and dynamic effects caused by flag movement; the submitted documentation shall demonstrate an adequate safety margin, excluding any risk of collapse, instability, or excessive deformation of the pole shaft or its anchorage system.

• Set up, clearly delimit, and fence the construction site, including access control points, safety signage, and protection of areas open to the public;

• Define and maintain designated storage areas for materials, equipment, and waste, ensuring their safe and orderly arrangement to prevent accidents and interference with site operations;

• Limit dust, noise, and vibrations by adopting appropriate working methods and equipment and, where necessary, using dust suppression, noise reduction, and vibration control measures;

• Keep the site tidy and clean at all times, regularly removing offcuts, packaging, debris, and materials no longer needed, and ensuring safe circulation routes for workers and vehicles;

• Restore any areas only temporarily affected by the works, bringing them back to conditions equal to or better than those existing before the start of the works.
