National Highways are the government company who plan, design, build, operate and maintain England’s motorways and major A roads, known as the strategic road network (SRN), helping customers have safer, smoother and more reliable journeys.
On 31 March we hosted a supplier day to provide details about this future opportunity. The purpose was to raise awareness of our long and short-term aspirations and enable the market to consider how they might participate in future procurement activities.
It was a great opportunity to meet and talk with colleagues from across the industry. If you were unable to attend the event in person, and would like a copy of the information that we shared on the day, please contact us at firstname.lastname@example.org
The works envisaged under this framework agreement will comprise Civil Engineering and Technology improvements (including but not limited to structures, geotechnical, junction improvements, roadside technology and environmental) on the M25 network and in some instances, combined with road infrastructure renewals works related to civil engineering and technology.
The works will be built into contracted packages optimised to suit needs, often multi discipline and sometimes phased. Contracts awarded under the Framework are anticipated from £100,000 up to £20m, with a total value estimated at up to £150m over a six year period commencing in 2023.
Our community currently comprises six main supply chain partners who work alongside our strategic supply chain partner, Connect Plus Services - working in partnership with Connect Plus. Together with the wider supply chain, we come together to collectively develop and share like-minded values, behaviours and initiatives.
Below are some examples of the projects we've undertaken across the network, working in partnership with our supply chain partners through previous call off frameworks.
From 2016 through to 2018, we successfully designed and constructed temporary slip roads from the M25 to the HS2 works compound between junctions 16 and 17.
These roads were vital in facilitating the construction of the Chiltern Tunnel, and reducing the number of HGVs and other works-related traffic on local roads. They were the first major works to be undertaken for HS2.
As well as having a positive impact on congestion and the resulting environmental benefits, taking HGVs away from local routes was a much safer option.
Structural works to strengthen the M25 Gade Valley Viaduct started in 2016, taking into account predicted traffic volumes over the service life of the Viaduct. Carrying an eight-lane section of the M25 over the West Coast Mainline railway, Station Road and the canal adjacent to Kings Langley, the Viaduct is an essential part of the strategic road network, carrying circa 150,000 vehicles daily.
The project is scheduled to complete by the end of summer 2022 and aims to prolong the lifespan of the viaduct and help keep journeys safe for all.
Junction 23 on the M25 in Hertfordshire is the single biggest gyratory on the whole of the National Highways network. At about 1.2km in circumference, it sees some of the highest traffic flows on the M25. The upgrade to the junction, which connects the M25 with the A1(M) for Hatfield at South Mimms, sees the widening of the southbound A1 entry slip road to provide a two-lane entry onto the southbound A1. This will ease congestion and improve safety. The upgrade also sees a new footway for pedestrians, that will link from the service station to the existing footway.
The transformation has made the junction safer and easier for drivers, and includes an upgrade of the traffic signals and signal timings to help improve traffic flow.
ROTTM signs provide a flexible and safe solution to providing warning signage to road users, as they approach roadworks. National Highways' roll out of ROTTM signs required that 10 signs, associated infrastructure and civils work, were all completed during 2020/21 along the A13 in the east of London, approaching M25 J30.
Each sign had its own localised constraints, including other roadside infrastructure, services and geotechnical challenges. A collaborative approach to design and construction allowed designers to benefit from the contractor's experience. The project was delivered successfully and the signs are now operational.
