Faro’s robot dog walked the aisles at World of Concrete and will soon be walking job sites to deliver scanned data on foundations, structural steel, walls, columns, reinforcing steel, slabs, stairs, and more. FARO partnered with Boston Dynamics, the maker of the SPOT robo-dog. Traditional laser scanning requires a person to operate a scanner throughout a jobsite, which could be anywhere from minutes to days of scanning, depending on the project size. SPOT is the most robust walking robot on the planet. By attaching a FARO laser scanner to the robot, individuals can walk the job site with the robot once, assign scan positions, then let the robot and scanner run autonomously thru the job site.
As described in the ACI-ASCC Committee 117 draft Guide to Using 3D Laser Scanning for Measuring Concrete Tolerances, “A laser scanner can provide dimensional quality control in three dimensions. This is a powerful capability in the hands of an experienced surveyor.”
At the World of Concrete 2020, the American Society of Concrete Contractors sponsored its third workshop on the topic, spearheaded by ASCC technical director Bruce Suprenant. The goal of these workshops is to develop a guide that “presents a basic understanding of the hardware, software, and methodology associated with the proper use of 3D laser scanning in the measurement of standard concrete tolerances.”
Laser scanning is increasing in usage on job sites of all kinds and sizes. This technology feeds into BIM models and can be used to avoid rework and provide evidence of as-built conditions. To learn more about how Largo Concrete is using laser scanners, click here.
