Simplifying Access to Laser-Scanning Data
As the popularity of laser scanning grows, being able to manipulate the data efficiently becomes ever more important. IMAGINiT Technologies' Scan to BIM software speeds workflows by giving Revit users direct access to point clouds.

Laser scanning has advanced by leaps and bounds during its relatively short history, increasing the accuracy and ease of a variety of measuring and modeling tasks. Whether you're creating digital terrain models, reverse-engineering car parts, or analyzing crime scenes, there's a laser-based technology that can help.
In architecture and construction, users have embraced laser scanning as a practical solution for collecting as-built data. There are often discrepancies between a building's blueprints and its current form, due either to changes during the original construction process or remodeling and expansion projects. For older buildings in particular, this information may have been lost — or never have existed in the first place.
"Scanning is a rapidly growing field," said Beau Turner, director of business development for IMAGINiT Technologies (a division of Rand Worldwide that merged with Avatech Solutions earlier this year). What's behind the surge in popularity? "A lot more projects are being retrofitted," Turner said, whether it's done to save money, preserve historic buildings, or achieve green design goals such as LEED certification. In the next 10 to 20 years, Turner noted, an estimated 60% of building projects will take place on existing structures.
According to Turner, companies are also attracted to the level of accuracy and the time savings they can achieve compared with traditional survey methods. "With laser scanning, you're looking at a millimeter of tolerance across an entire structure." Improvements in the capabilities of scanning technology are also spurring adoption: "Even a year ago, [the number of points collected for a project] measured in the millions; now it's in the high millions and billions of points."
