The concept, named ‘In-Site’ aimed to deliver a leap forward in bringing functional, wearable AR to the construction sector, and perform three basic functions:

1. Identifying an asset

2. Pulling information about that asset from the cloud (and delivering into the operative’s field of view)

3. Pushing information about the asset back from the operative to the cloud.

This functionality could be applied across a range of activities at the Crossrail site, however focus was given to two key elements: commissioning and handover stages. This supported enhanced efficiency in logging and reporting on installed assets in Crossrail tunnels, which could be carried out more swiftly, safely, and reliably than previously; by allowing operatives to perform key tasks hands-free and with their heads up.

PROJECT: InnovateUK’s IC Tomorrow Competition


In 2015 Sublime applied for Innovate UK’s “IC Tomorrow” competition, that offered the opportunity to work in partnership with Crossrail to investigate real industry uses for augmented and virtual reality. The broader impetus for the project was the desire to explore ‘Smart Construction’ via new immersive technologies, aiming to deliver improvements in efficiency and safety.

Sublime’s winning entry was granted £35,000 to invest in an AR wearables concept and trial it on-site at Crossrail’s Liverpool Street site, working in partnership with their contractor, Laing O’Rourke.


Trialled at Liverpool Street Station, the Crossrail and Innovate UK project demonstrated that the Sublime ‘In-Site’ application could deliver exceptional benefits in efficiency and safety if further evolved for the construction and manufacturing industry.

The final prototype was delivered in late 2016 and since then, Sublime has partnered with Crossrail in various stakeholder engagements to demonstrate the feasibility of the augmented reality solution.


“It has been incredible to see proof of concept, with this technology and solution working on a live construction site. We are incredibly proud to have worked on this programme, and the innovation that will drive new levels of efficiency, safety and capability on sites like the Liverpool Street Station.”

William Reddaway, Innovation Programme Manager at Crossrail
