How 3D Laser Scanning Improves Accuracy of Design-Build Projects


When it comes to building a new or renovating an existing facility, one thing is for certain—gathering information can be taxing.

That’s why ESI Group, Hartland, Wis., invested in a 3-dimensional (3D) laser scanner.

The 3D scanning market is expected to grow above $8 billion by 2025, according to Grand View Research, Inc., San Francisco. Furthermore, the Rhodes Group, Pittsburgh, Pa., reports 3D laser scanning can reduce total project costs by as much as 5-7%, and can condense the schedule by as much as 10%.

“The scanner will take a 360-degree photographic image, then overlay hundreds of thousands of laser-reflected measurements to create a virtual 3-dimensional image of a space or room,” says Joe Barke, preconstruction manager. “Multiple images can then be assembled together to provide a 3-dimensional image of the space showing structure, equipment, and utilities.”

3D laser scanners provide insight into every aspect and phase of construction, from initial concept to the completed project.

“Utilizing a semi-autonomous machine to collect, analyze and assemble data into a functional virtual workspace will maximize the probable and minimize the hypothetical,” adds Barke. “Accuracy begets efficiency. This is just another small tool in the box to combine the latest design technology available to a modern design-builder.”
