This is the sixth article in the Precision Construction series, which explores the application of the Internet of Things to digitally transform the construction industry, ultimately with the objective to improve labor productivity, reduce costs and enhance safety. The series began with Exploring Digital Transformation for Construction, followed by Simplifying Complex IoT Solutions, United Rentals Drives Efficiency & Excellence with IoT, United Rentals Helps Customers Optimize Equipment Rental, Robotic Masonry Is Helping to Fill the Skilled Labor Gap, Taking Environmental Monitoring to a New Level and Digital Transformation – Enabling New Business Models for Construction. Articles generally follow a five-layer framework, described in Simplifying Complex IoT Solutions, that makes it easier to understand digital transformation solutions.

One technology available to the digital contractor for mapping what’s happening in the physical world with the 3D models is mixed reality. Mixed reality often includes both augmented reality and virtual reality.
During the preconstruction design phase, mixed reality can be used for a number of tasks, such as:
Mixed reality can also be used to create marketing material, such as a virtual showroom. Imagine being able to show a potential client what the building will look like. For example, the client, wearing mixed-reality glasses, can see the physical neighborhood with the building or can take a virtual “walk” through of an apartment before it it is even completed.
During the construction phase, mixed reality has a number of potential uses, such as:
Mixed reality can also be used in facilities management. It’s well known that the cost of constructing a building is a fraction of the total cost of maintaining a building over its lifetime.
If the contractor has kept the BIM model updated throughout the construction process, this model can be provided to the owner at the completion of the project. Then if redesigns are requested, the owner can use the mixed-reality glasses, for instance, to see through walls and ceilings to know where structural elements are located.
Mixed reality can also connect to IoT devices in the building, such as networked water towers and boilers. The wearer of the mixed-reality glasses can look into a room and the different connected machines can show their current state. This allows issues to be recognized simply by looking at the machine.
Actually, mixed-reality glasses are not required to visually see the 3D design overlaid with the physical world. Although still in early development, there are a number of apps available now that use the mobile device’s camera to overlay an interactive BIM model. Using a mobile device might also work better when outdoors, as today’s mixed-reality glasses don’t do as well in bright light.
