Skanska and Balfour Beatty have credited sustainability, technology and communication for finishing an M25 project 22 weeks early.
The two construction giants formed a joint venture to deliver a 19km-long smart motorways scheme between junctions 5 and 7 of the London orbital motorway.
The project, in Kent and Surrey, will allow drivers to use the hard shoulder of the road for normal driving, and assist traffic flow using overhead technology.
Skanska Balfour Beatty said building information modelling had reduced the need for manual redesigning; retaining existing structures had cut the volume of deliveries; and community engagement had kept work on track.
Kieran McGibbon, engineering director for the JV, said: “I’m very proud that we have delivered a project 22 weeks early, which has set new standards in our industry in terms of accelerated delivery across all project disciplines, sustainability and the implementation of digital design.”
Should more projects finish early now we have better technology? Or is this a one-off? Tell us your views in the comment box below.
