Electrical services

Description

This procurement related to the provision of street lighting and other external electrical services to Belfast Harbour Commissioners (BHC), including traffic light inspection and repair works for BHC. BHC has established a framework agreement under which suitably qualified and competent contractors have been appointed to carry out certain works in relation to street lighting, traffic lights and other external electrical services within the Harbour Estate. BHC operates street lighting on approximately 26 km of roadway, car parking and other spaces within the Harbour Estate. There are approximately 2 500 street lighting fittings within the Harbour Estate. All street lights are supplied from a list of substations located throughout the Harbour Estate. The majority of street lights are 10 m high standard street lighting columns fitted with an outreach arm with either 95 w SOX, 135 w SOX or 150 w or 250 w SON luminaires. There are a few street lights mounted on buildings and a few extra flood lights mounted on the street light columns. Some of the lighting circuits are controlled by a lighting contractor mounted in a substation switched by a photo cell. Others are controlled by individual photo cells mounted on each lamp standard. There are 10 road intersections and pedestrian crossings controlled by traffic lights. The services required by BHC comprise a monthly inspection of all street lights in the Harbour Estate, provision of more detailed unit inspections and a repair and installation service. With the exception of the monthly inspections, the scope and quantity of the remaining services will be variable and will be determined by BHC as required.
