Future Forward: Innovative Mixed-Reality Technology Improves Construction Monitoring

Todd Danielson on April 3, 2019 - in Articles, Profile

This page profiles innovative and impactful applied research in civil and structural engineering to spur continuing thought and dialog to create a better industry. These profiles are based on interviews, and the opinions and statements are those of the subject and are not necessarily shared or endorsed by this publication.

Nancy Li is the Global Head of Partnerships and Industry Solutions for Microsoft’s Mixed Reality and AI Perception group.

A video of the interview is available here.

The Future of Construction

The design and construction industry has moved from pen and paper to blueprints to printed CAD drawings to rugged laptops to mobile tablets. A future of 3D holograms being manipulated by engineers and stakeholders has been on the horizon for a while, but it appears that this particular future has arrived.

Nancy Li has been speaking about one particular technology package that combines Microsoft’s HoloLens (HaloLens 2 has since released in February 2019), Azure cloud services, AI and IoT technology with Bentley Systems’ Synchro Software to create a mixed-reality construction management solution seemingly straight from a science-fiction movie.

“We’ve been working with Bentley Systems and specifically with Synchro for quite a while, and we started a conversation about them building mixed-reality solutions two years ago,” notes Li.

The Pieces

Synchro is a 4D construction modeling solution that adds the element of time. The platform provides a fully integrated critical path method (CPM) scheduling engine with interoperable CAD capabilities. Linking with HoloLens allows users to interact collaboratively with the 4D construction model aligned with physical space, using intuitive gestures to review, validate, track and experience construction sequencing.

“HoloLens, in general, we call mixed-reality technology,” adds Li. “It is essentially a technology that can bring lots of virtual reality, virtual data information and virtual objects into the physical world.”

Comparing the system to “Iron Man” from the Marvel movies, she notes that construction workers can access information in front of their eyes, not only as a heads-up display, but also bring this virtual information in context relevant to the physical world.

“You actually can see the real-time data right next to the IoT sensor, instead of seeing it on a 2D screen in a back operating room with somebody staring at a monitor somewhere,” she adds.

FC Barcelona

As an example use case, she describes how the FC Barcelona football (soccer in the United States) team starring Lionel Messi is rebuilding its world-famous Camp Nou Espai Barça stadium without closing to the public during the season.

“Every weekend, they still have to welcome a hundred thousand people to come into the stadium to watch the games while the entire construction is going on,” says Li. “That requires accurate construction monitoring, which the existing technology does not enable. So they looked to us and Bentley to help them create a construction monitoring solution.”

The construction system takes IoT camera information of the construction site and overlays it with Bentley 4D models on top. This enables remote monitoring with Microsoft computer-vision services to perform accurate alignment and remote construction monitoring. Instead of having to come to the site each week, HoloLens allows stakeholders to inspect the progress of the construction through mixed-reality viewing to spot construction mistakes as quickly as possible.

She notes that discrepancies in pillar placement, for example, are much easier to spot via this mixed-reality system.

“You immediately see from a 3D representation of a visualization through HoloLens, you know that this thing is 3 feet off,” she adds. “And that gives a lot of efficiency to construction inspection.”
