Execution of vertical lighting along with commissioning at the pedestrian crossing along the voivodeship road No. 846 in the city of Wojsławice in accordance with the detailed technical specification and description of the subject of the contract

Execution of vertical lighting along with commissioning at the pedestrian crossing along the voivodeship road No. 846 in the city of All materials and elements of the installation must have appropriate certificates allowing them to be used in construction, attestations, declarations, etc. The contractor carries out commissioning of individual installations, provides instructions or DTRs and provides a guarantee of proper operation for all works performed and elements delivered

b) F-100 type prefabricated foundations are intended for the foundation of lighting poles. The foundations must be made of reinforced concrete class C25/30 with appropriate channels for cable entry. Depending on the size, the foundations are made in a single concrete block version or are split and screwed together. Depending on the specific location conditions and the type of groundwater, corrosion protection must be performed. c) for road lighting, use light sources and luminaires that meet the requirements of PN-83/E-06305. Luminaires should have a wide light distribution. For operational reasons, luminaires with a closed structure should be used, the degree of protection against external influences of the lamp chamber min. IP 54 and protection class II. Luminaire components such as optics and body should be made of stainless materials. The luminaires should be stored in rooms with a temperature not lower than -5oC and relative air humidity not exceeding 80% and in packages compliant with PN-86/O-79100. 34 W ,Luminaire flux min. 3600lm for right-hand traffic using asymmetrical lenses. The luminaire diffuser is made of material with an impact coefficient of min. CI 8. It is possible to mount the luminaire on a horizontal boom and vertically on a pole with a diameter of 42 – 60 mm. The luminaire body is made of high-pressure powder-coated aluminum. The luminaire must be able to be vertically adjustable in relation to the illuminated surface in the range of -15° to +15°C.,d) The poles should carry the loads resulting from the suspension of the luminaires and brackets as well as the wind pressure for the II and III wind zones, in accordance with PN-75/E-05100 In the lower part, the poles should have one recess closed with a door.e) The booms should be made of seamless steel pipes. The wall thickness of the pipe should be 4mm. The boom arm is inclined at an angle of 15 degrees from the horizontal, and their reach should allow for illumination of both the access to the crossing and the entire pedestrian crossing. The booms should be protected against corrosion with a galvanized coating. Storage of booms on the construction site in a dry place protected from damage.f) The kit shall have a controller capable of transmitting the energy obtained from the photovoltaic panel and the wind turbine to the batteries and the luminaire. The hybrid set must be equipped with a twilight sensor that allows the set to switch on and off automatically. The sensor must be powered by direct current with a voltage of up to 12-24V. Control and programming should be done by means of an infrared remote control. The cables used to connect the control cabinet with the luminaires should meet the requirements of PN-74/E-90184. Wires with a nominal voltage of 750V, multi-core wires with PVC insulated copper conductors and a conductor cross-section of not less than 2.5 mm2 should be used.g) The power supply system includes:- a battery mounted in the ground min. 180Ah with a voltage of up to 12V – 1 pc.- wind turbine with a power of min. 250W. The turbine must be equipped with a brake protecting against damage that activates when the wind speed is too high – 1 pc. – photovoltaic panels with a power of min. 190W – 2 pcs.h) Grounding should be made in the lower part of the foundation trench by means of a rod earth electrode plunged diam. 14.2 mm. The rod earth electrode is connected to the pole by means of a cooper
