Technology is playing an increasingly important role on construction sites, improving productivity, visibility and collaboration. Ambar Kelly is utilising the latest AR (augmented reality) software – a Trimble Connect for Hololens plugin from tech company Trimble Tekla – to trace and analyse the installation of its patented solution RiserSafe® on Square Mile’s latest skyscraper 6-8 Bishopsgate, London. The use of this technology is streamlining project delivery and assuring collaborative working across the various disciplines involved on this part of the build.

8 Bishopsgate is a £300m project designed by architect Wilkinson Eyre and will offer 52,954sqm of modern office space and retail facilities at its entrance. Located on the corner of Bishopsgate and Leadenhall Street, the distinctive design will feature a ‘stacked’ three-block scheme, architecturally complementing the iconic Cheesegrater aesthetic of the Leadenhall Building beside it.

Ambar Kelly is collaborating with main contractor, Lendlease and contractors T. Clarke, MJL, Hall & Kay, Gardener & Co, concrete frame contractor Keltbray Structures and steel frame contractor William Hare to coordinate the supply and install of RiserSafe with the structural frame and M&E services. RiserSafe® was selected as a result of Lendlease’s commitment to ensure safe working practices onsite. Over 1,300 riser openings will be protected by Ambar Kelly’s patented RiserSafe system – which is able to seal riser floor openings and in one action, eliminating falls from height and preventing the passage of smoke and flame in the event of fire.

To drive quality and accuracy during RiserSafe’s installation, Ambar Kelly is utilising the latest Trimble Connect for Hololens technology from software provider, Tekla. Users put on a 5-microphone array and innovative bone-conductive headset to provide crystal clear 2-way communication in noisy environments. This digital solution uses mixed reality for coordination by providing precise alignment of holographic data on the construction site or in the factory, enabling workers to review their 3D models overlaid in the context of the physical environment. The level of early engagement and the aid of technology is ensuring the RiserSafe® units can be installed accurately and easily, assuring a seamless project delivery for the benefit of all construction teams.

Speaking of how the technology is aiding work onsite, James Cousins Contracts Manager at Ambar Kelly says: “The Hololens plugin is a fantastic visual tool for the client and architect to see how the project is moving, and proves to be particularly helpful when viewing how the project will unfold in an un-built environment. Without the technology this would be an arduous process; thankfully, Hololens gives everyone the earlier engagement that they need. It will also serve as a clear audit trail of which changes have been made, creating that all-important golden thread of information.”

“As well as giving better visibility of any changes, the AR technology is enabling collaboration, something that has been repeatedly called for in construction. All approved drawings are uploaded into the helmet. You can then collaborate with other users using the same equipment to align, navigate and measure the model in a real-time, true-to-life space. We can also manipulate the model whilst onsite which is an added bonus. When it comes to onsite installation everything is there, everything is cut and manufactured to the detailing in the model. The efficiency of the modelling is second to none, and it is keeping project teams better connected.”

The Hololens plugin is part of Ambar Kelly’s evolving suite of digital solutions. Ambar Kelly has used the Tekla Structures software on the 1 Triton Square project to great effect.

Set to be a striking addition to London’s skyline, on completion 8 Bishopsgate will be feat of contemporary engineering. The use of mixed reality technology on this project will no doubt be a benchmark for collaboration and visibility; two factors that the construction industry has long-needed to improve upon.
