The construction giants have been working on a joint refurbishment venture of the M25 since May 2009 and after adopting a BIM process, the duo have shaved 36 weeks off the original timetable for the completion of the work. BIM software allowed for the team to spot design faults at an early stage and provide the Highway Agency and shareholders with real-time information whenever they requested to see it.
The update to the large piece of infrastructure involved improving 72 miles of the motorway through Essex, Hertfordshire, Kent and Surrey. The road has been bulked from 3 to 4 lanes in both directions, with the hard shoulder now enabled for use as an extra lane. The overhaul also included the installation of new technology such as CCTV cameras, emergency telephones, overhead signals verge mounted signs and more.
Construction Enquirer has reported that the firms met incredibly-high sustainability targets during the project too, with 90% of materials used coming from recycled resources – an impressive statistic indeed.
“I am very proud that we have delivered the last of our current projects to upgrade the M25 to Smart Motorway and in doing so have set new industry standards in terms of accelerated delivery and sustainability for motorway upgrade projects,” Skanska Balfour Beatty’s Engineering Director Keiran McGibbon said of the project.
The Chief Executive of client Connect Plus, Tim Jones, also provided his thoughts on the speedy delivery. He stated: “Over the past 65 months, the Skanska Balfour Beatty joint venture has set numerous benchmarks in productivity, design, safety, sustainability, technical innovation and programme efficiency that are unparalleled in the history of highway construction.”
