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.”

Collaboration is currently our industry’s favourite buzzword, so here it is, in action, delivering rock solid results for the benefit of the UK’s road network.Working with our clients, Connect Plus & Connect Plus Services, Jackson carried out some trials of a new waterproofing agent, Matacryl on the M25 Mardyke Viaduct. The benefit of Matacryl is that it’s easier to apply, quicker to cure, and can be installed under far less stringent weather conditions than conventional waterproofing materials, which means far fewer delays to waterproofing works. Our Framework Director Paul Watson explains: “The initial trial was a great success however, we faced a real challenge in sourcing the material due to a lack of suppliers in the UK. To solve the problem, we worked with the manufacturer, RPM, and one of our supply chain partners Techjoint, who agreed to get involved. As a result, Matacryl is now being used widely across the UK’s road network, reducing delays to waterproofing works, and keeping the traffic flowing.” Mark Healy from Techjoint said: “As a result of the collaborative nature of our relationship with Jackson and Connect Plus, we were confident enough to invest in new plant, equipment, training and development of new products. The Jackson/CP team are always there at the end of the phone if we ever need any advice, even on competitor’s projects and this is something that is unique in our business.” The results from the initial trials have since been shared with other Framework suppliers through the Research and Development Forums, and the Collaboration Portal, and Matacryl is now widely used across the UK’s highways network. Furthermore, this relationship, a shining example of best practice collaboration with the supply chain, has led Jackson to be shortlisted for the NEC Contractor of the Year award, which has a particular emphasis on clause 10.1 – the obligation to act in a spirit of mutual trust. The winner will be announced at the NEC Annual Seminar at the end of this month.
