Kent County Council is one of the largest lighting asset authorities in the UK with 118,000 street lights and some 25,000 lit signs and bollards. The annual cost of illuminating and maintaining the stock is over £9m, a cost that continues to rise. The main focus of the project is to reduce the cost of illuminating and maintaining these light sources by converting them to more efficient LED products. Bouygues Energies & Services were appointed after a successful tender bid by the council to manage the installation conversion from HID to LED lanterns. The P852 luminaires are manufactured in Coleford, Gloucestershire to a forward schedule. The advantage of producing the luminaires in the UK means that CU Phosco Lighting can react quickly to any site changes or deviations that can occur. This assists the contractor in improving efficiencies in the program as well as reducing any delays to the road schedule. During the supply of the luminaires CU Phosco Lighting and Bouygues Energies & Services are working in partnership with their design consultant (Designs for Lighting) to a forward planned site schedule ensuring minimal distribution to the road network and public users. The schedule outlines CU Phosco Lighting production for quantities and geographical boroughs within the county. This provides clarity for both CU Phosco Lighting and Bouygues Energies & Services to maintain delivery of the project in a professional, efficient and organised manner. The production programme was assisted by Designs for Lighting who are designing every asset to ensure compliance with standards and optimised energy efficacies, the luminaires used were carefully considered for efficiency and maintenance and concluded that five versions of the P852 to be used with two optics. This enabled a much more efficient production and installation programme.
