Calling it the next generation of construction quality assurance/control methodology and technology, Verity and GeoSLAM are integrating simultaneous localization and mapping (SLAM) with building information modelling.

GeoSLAM and ClearEdge3D announced a beta program that allows as-built construction data measured using GeoSLAM’s hand-held, lightweight mobile laser scanners to be compared against design/fabrication models using ClearEdge3D’s Verity software to identify installation status and out-of-tolerance or inaccurately constructed work.

“Leading AEC firms from around the globe - users of both ClearEdge3D and GeoSLAM technologies have been encouraging us toward this innovation,” said Mark Reid, vice president of product management for GeoSLAM.

“Hand-held mobile laser scanning is faster and more accessible than traditional static terrestrial scanning,” Reid continued. “The savings, both in terms of verification time and reduced rework, is enormous.”

According to the company, nearly any member of a construction project team can use a GeoSLAM scanner to gather jobsite data for analysis. The need for traditional survey methodology is reduced because the ZEBREVO is changing the economics of laser scanning, allowing users to scan more frequently – even daily. That data can then be analyzed in Verity software to make sure the work is being built on schedule and within tolerance; identifying mistakes before they become expensive problems.

“The plan is to have Verity do the same thing with SLAM data as it does with traditional terrestrial data—to very quickly and accurately verify installation status and tolerance,” said Kelly Cone, vice president of product management for ClearEdge3D.

“Our customers understand the value of terrestrial scanning, but it can be cost prohibitive for weekly or daily use. Augmenting terrestrial scanning using GeoSLAM’s hand-held mobile scanners gives our clients the freedom to scan as often as they want.”
