M4 SMART MOTORWAY UPGRADE J3-12
Hayes to Theale, Berkshire, England
Construction Joint Venture Balfour Beatty/Vinci (BBV)
Autumn 2018 – Spring 2022
The M4 is the main strategic route between London, the West of England and Wales. It connects people, communities and businesses, carrying on average 130,000 vehicles per day, and is prone to congestion.
The improvements to the M4 between junction 3 at Hayes, and junction 12 at Theale, will involve upgrading the motorway to a smart motorway, which will provide much needed capacity, supporting the economy and facilitating economic growth within the region.
This means there will be:
- An additional lane for traffic, increasing capacity and reducing congestion
- More technology on the road to smooth flows and manage incidents
- More reliable journeys
This contract is the longest smart motorway upgrade project in England to date, at 51km or 32 miles.
Working under narrow lane traffic management created tight working envelopes in which to deliver both the central reserve slot drain and DCB, and hard shoulder slot drains.
Through ECI, and regular technical and operational consultations with BBV, the limitations and opportunities were managed to deliver the works in the most efficient manner.
In order to ensure a high-quality concrete supply to the slipform operations, PJ Davidson’s own CEMCO mobile batching plant was deployed to the project, establishing a BSi accredited concrete source as close as possible to the workface with the capacity to supply all of the contracted works.
