On-Site Laser Scanning

Accurate Laser Scanning Services

With the ever-increasing cost of building new structures, as well as the decreasing space in which to build them, many businesses and organizations are opting to renovate existing historical structures. Usage of laser & Lidar scanning services has gained enormous popularity, where space is often at a premium. G&P's high-speed terrestrial laser scanners can capture the site quickly, accurately, and more inexpensively than manual measuring or conventional surveying techniques. This can create detailed floor plans and BIM models from which to work from.

The appeal of using laser scanning and as-built services is that projects can be estimated more accurately, they take less time to complete, the work is of better quality, and the cost and risk of execution go down. Better graphical documentation of existing site-work leads to improved visualization of proposed projects, so private, public and governmental acceptance of 3D point clouds and modeling is easier to understand.

In addition to the obvious benefits to the construction and renovation industries, terrestrial laser scanning is used in virtually any large-scale structure or environment that needs to be documented. Civil engineers use laser scanning to digitize existing and proposed locations for roadways, bridges, tunnels and more. With the exact topographical features, they can calculate volumes, contours, and many other aspects of infrastructure construction. Once construction is underway, laser scans are used to inspect the work at various intervals, making sure that plans are accurately executed and will uncover design flaws before they become costly and time consuming.

Similarly, terrestrial laser scanning is invaluable in conditions that are less than optimal for manual measurements; such as work being done on huge oil rigs or in poorly lit areas such as mines and tunnels. The laser scanner can take accurate measurements even in the dark. Another application for the laser scanner is documenting the scene of a crime or an accident. The high-speed scanners quickly collect detailed data of everything that is within range with minimal intrusion. Nothing is moved by non-contact measurement, keeping the integrity of the scene intact. The 3D data is then exported to special forensic software for modeling and contouring, creating a realistic view for the investigators to examine visually allowing them to be able to determine the sequence of events and possible causes.

Bottom line, On-Site laser scanning is an extremely useful service that is here to stay. Combining proper field techniques and work processes with experienced, knowledgeable personnel results in the most accurate, detailed, and cost effective site mapping solution available.
