BIM & PROJECT MANAGEMENT
the vital new link at Ordsall Chord.
The work comprises of a multi- disciplinary rail engineering design at Network Rail GRIP 3 stage to produce an agreed concept design. But with regards to BIM Maturity Levels on the programme, Network Rail has taken a phased approach.
Stacy said: “On Northern Hub, Network Rail wanted to be at Level 2 by 2016, but they didn’t think it was possible to go from a standing start – Level 0 and CAD before the project started – to full BIM in one jolt.
“But by the end of concept design at the end of GRIP 3, Network Rail would like to be working at BIM Level 1, which is the managed data environment.
“Further development and progress is anticipated to deliver BIM Level 2 on the next stage of the project during the detailed design.”
He added that one of the main challenges with using BIM on the project is that it is a developing technology and the standards for it are not yet fully defined. However, the benefits outweigh the challenges, he believes.
Industry norm
“If you look at the benefits we’ve seen even through early adoption on this project, there
A way of working
“Other than a digital-tool set, you don’t actually ‘use’ BIM. It is a way of working, it’s what you do: information modelling and information management in a team environment. The rich 3D experience; digital simulations; rehearsals of all stages of the design, build and operate process; the information within the models facilitates well-informed decision-making, resulting in better business outcomes, clarity, improved communication, de-risking and ultimately better efficiency.”

are so many benefits that I’m sure it will become the industry norm,” said Stacy.
The team has seen improvements in design efficiency on the Northern Hub, despite the necessary learning curve to deal with the new processes. But BIM allows the team to focus on the critical areas and interfaces on projects.
He said: “Because you are working in the 3D environment, you are challenged to sort out some of the problems that, if you were working in 2D, you might have been able to draw over or work around.
“As long as you don’t go into too much detail – which could be a waste of resources – it
de-risks the design at future stages, because you’ve already worked through the problems in critical areas.”
Stacy and his colleague Nicolas Geroudes updated the audience at Infrarail 2014 on BIM progress on the Northern Hub, including a live demo of the BIM model, with topics covered including the modelling of existing structures, generating geometry from point-cloud surveys, a walk-through of the model, signal sighting, the railway systems functional check, and the overall ‘fit’ with Manchester’s architecture and heritage.
Rail Technology Magazine has previously explored how BIM and 4D modelling is being used on Network Rail’s Reading upgrade (Feb/ March 2012), TfL’s Victoria station upgrade (Feb/March 2014), and the plans to embed it at the earliest stages for HS2 (Feb/March 2014). We will explore BIM’s use on Crossrail in a future edition.
