Introduction
When 3D laser scanning appeared on the construction scene in the early 2000s, there was
finally a tool that could scan and collect precise, as-built measurements and site conditions.
Scanning could replace previous manual processes that were far less accurate and more
tedious, like tape measures and 2D drawings.
But only recently has the computer hardware and CAD software technology evolved to
support scan data, allowing it to more fully enable BIM and other construction workflows.
This has led to the rapid rise of scanning and turned it into a go-to tool among contractors.
3D laser scanning is especially useful for:
ý Renovation and redevelopment projects that lack existing or current drawings and
maintenance documents, giving you the ability to capture as-built conditions.
ý New construction projects, where having reliable scan data about project conditions
ensures accurate construction of the prefabricated assembly before installation,
minimizing mistakes and rework.
ý Construction project progression, by allowing you to track and compare each new phase
of work against a model or drawings, as well as record project milestones and produce
accurate as-built documentation.
While there's no doubt that 3D laser scanning brought important capabilities to the
construction industry, today's laser scanning tools also have limitations and present three
common hurdles that can cost you time and money:
ý Specialized technical training is required to use the tool
ý Incomplete or inaccurate project information creates inefficiency and costly rework
ý Required calibration takes the instrument out of commission, hurting productivity
Let's take a closer look at these challenges and explore solutions that can help you improve
and expand upon your current workflows and scanning processes.
