Terrestrial Scanning/BIM

Laser Scanning is changing the surveying/mapping industry and Langan has been leading the revolution since the addition of High Definition Laser Scanning services in 2003. In scanning, the data collected is known as a “point cloud,” which contains a 3D database of the entire project area and allows the measurement of any surface information that is visible in the cloud to be used during the entire project lifecycle. After processing, the data from the “point cloud” can be utilized to produce dimensionally correct 3D models and/or 2D dimensional plans, with outputs to Microstation, AutoCAD or a host of other platforms. The registered data can also be used as a base to create highly detailed site visualizations or mass models. The end data can be used for building information model (BIM) support, forensics studies, to determine possible construction conflicts, to validate construction/fabrication dimensions, or even to model major motion picture sets.

Our ability to offer a combination of High Definition Laser Scanning and conventional surveying methods allows us to deliver a complete product.  With prior technologies, the end user had to work "on the data."  High Definition Laser Scanning allows the end user the ability to work "in the data" and be on site virtually with the push of a button.  As with all of our surveying services, the scanning effort is overseen by Professional Land Surveyors, who bring experience and knowledge of traditional methods to this cutting-edge technology.
