A senior figure at the London Underground has hailed a project team’s success after renovating the Victoria Line and opening two days ahead of schedule, with BIM being a crucial part of generating that efficiency.

LU’s Director of Capital Programmes, David Wabaso compiled his thoughts on the recent Victoria Line extension, allowing for the track to run 36 trains to run per hour, the highest amount for one line in the UK, and one of the highest figures in the world. To deliver a line of such importance, efficiency was crucial. David explained the part that BIM had to play in the project.

“The team, using BIM, developed a 4-D model that allowed cost/time/resource to be tracked in a very visual way and at the touch of a screen, the progress of the job could be shared remotely on smartphones and tablets,” stated Wabaso. “The off-site fabrication and testing of all the components including the new point machines really paid off as the installation on site had to be to millimetre accuracy within the tight deep tube constraints.

“Our teams of engineers and testers also did a fantastic job and the buses and traffic management overseen by an overall TfL command and control structure, was a massive success.

“Then the news came through that work would finish two days early so we opened the railway to customers. And there it was – our biggest ever blockade, delivered safely, reliably, ahead of time and within budget. A success story for all the team and I would like to think, for the rail industry.”
