Jackson recently replaced all 193 street lighting columns and the 3km cable management system on the QEII Bridge at Dartford for Connect Plus.
The new system, developed in collaboration with our supply chain partners MWay Communications and designers Mott MacDonald, involves a plug and socket arrangement which allows the new columns to be easily removed and replaced in the future. The power supply to each individual column can be easily isolated, negating the need for specialist access equipment, thus improving operator safety. Fuse protection was also included within the plug design, negating the requirement for a cut-out and column door, reducing the risk of corrosion.
Height of the 193 columns across the bridge span was reduced from 10m to 8m and the replacement of 150w SON with 86w LEDs has equated to around 40 per cent energy saving. With the lighting linked to the CPS Central Management System further energy savings using dynamic dimming and adaptive lighting are potentially possible. In total, the team managed to save £400,000 through value engineering on this £3 million scheme.
M25 energy manager and street lighting asset manager Paul Barlex said: “When designing renewal schemes, whole life cost and maintenance play an integral part in our design approach. Early contractor involvement ensured that specialist knowledge delivered a lighting installation that meets the asset requirement as well as delivering energy efficiency.”
