Jackson Civil Engineering working with the M25 community has won national recognition for its innovative reorganisation of working shifts that led to significant improved customer road user experience, reducing safety risks and environmental impact.
The team picked up the national Constructing Excellence award in the Value category after transforming the delivery of the multi-element joint replacement schemes on the M3/M25 interchange by introducing Weekend Wonder-Shifts, which provided a more efficient programme of works. The Weekend Wonder-Shifts ran from 10pm on Friday night to 5am on Monday morning, enabling six teams to relay and work around the clock for 55 hours straight. This eliminated the costly delays associated with conventional working patterns avoiding the need to mobilise and demobilise the sites between shifts.
Working alongside joint suppliers Maurer and companies HW Martins, Tarmac and TechJoint, Jackson’s approach brought a number of benefits compared with working to traditional replacement techniques worked over multiple closure shifts and types.
Road closures became more predictable for drivers and were cut by more than 90%, meaning there was less impact on the travelling public. The safety of staff and the road user was also improved, as workers spent less time on the road – in fact, no incursions and safety observations relating to traffic management were reported on this job.
In addition, rapid strength concrete developed with Axtell on the M25 for PQC bay replacement was used in a different application to ensure the joint replacement work could be completed and the roads reopened in the time frames available.
There were also important environmental gains. Eliminating the use of traditional complex temporary works resulted in a reduction of the use of certain materials on the project, such as concrete, asphalt and steel bolts. The team calculate they saved 60 tonnes of CO2 across the project as a result.
Jackson picked up the London and South-east regional Constructing Excellence award for this project last year and the team was delighted to be named the winner at the national awards, held online last week.
Head of Constructing Excellence, Alison Nichol said: “This award is recognition of the brilliant work that Jackson has been doing to work collaboratively with their clients, understand their client’s needs and deliver long-term outcomes and value.”
The schemes were also delivered for 30% of their original predicted cost and with 10% of the person-hours compared to the original method, cutting approximately three months from the project programme.
Jackson’s Framework Manager, Ryan Smith said: “Productivity during the Weekend Wonder-Shifts is exceptionally high, as they give us the opportunity to get the bulk of the removal and replacement of the joint done in one go."
