front line, and how that project will cope as technology changes. Crossrail will face the same issues during its operational life, but the construction phase is already more than 60% complete, and tunnelling is just weeks from completion.
The project’s technical information, delivery and innovation departments have all helped ensure mobile data is used intelligently. in the technical information department called the information

– particularly useful for the initial phases of the construction, but the systems people are particularly interested in it as well, to see how the equipment will be phased in.”
Trusting the data
Augmented reality is a fascinating hint of the possibilities unleashed when high-quality asset information, digital connectivity, mobile devices and geographic information come together. The idea is that a tablet or smartphone pointed at an asset out on the physical infrastructure, whether a section of track, cables buried behind a wall, or malfunctioning pump, can overlay the image with useful information drawn from the database. It can also allow the database to be updated as repairs or changes take place in the real world.
for certain situations. But the data still has to
be correct behind it, and that’s the same with the visualisations. They can allow you to ‘look behind’ walls without actually taking the wall you know for sure where the cabling is, and the system has been told ‘it’s here’, and it hasn’t been moved, and everyone has always followed all the processes.”
in the real world, it is hard to guarantee that – especially if safety or performance could be compromised if the data about an asset is wrong or out-of-date.
Network Rail has been struggling with similar issues of safety and assurance when it comes to asset information. The director of its asset Patrick Bossert, told us last year how plans for ‘self-service’ buried services enquiries had to be put on the backburner because the organisation wanted to ensure scrutiny by a competent buried services engineer was still part of the process. As Bossert told us: “Clearly there’s a lot of safety risk associated with those services, and it’s not something we’d want to do without all right assurance processes in place.”
The next level
an asset is, and begin to see anything that adds value as an asset: whether a physical object, a
“In essence BIM Level 3 is about moving from a common data environment into an open world, go, but software suppliers and vendors have their own formats. That dialogue could take
“If we had an open format, it’d be a lot easier for changes at an alarming rate, so you’ve got to make sure your data’s structured in an intelligent way, so it to cope with whatever technology you throw at it.”

“I suspect BIM Level 3 will be about involving people too. It’s something we’ll aspire to, realism with your ambition.”
chain concerns about standardised data formats, and its proposals to be more ‘agnostic’, integrating the data at a later stage in the process to help lower-tier suppliers. Crossrail, by contrast, “made a very deliberate move to have one data format that all contractors have mean they can’t use other software, to a point – although that’s a bit futile, as they may as well get used to the one we’re asking them to use.
“For us, it’s sensible. It means we can co- got, be it mechanical, civil, architectural, etc.
“If we didn’t do that, we’d be in a right mess and we wouldn’t be able to assure anything correctly. That may cause some problems for the contractor; but it’s the client setting the requirements.
