Precision is not only a nice thing where construction, engineering, and architecture are involved—it's essential. Design based on assumptions comes with a steep cost in the form of costly errors, lost time, and design disagreements. Such technologies as point cloud scanning are becoming the norm. They will enable practitioners to measure actual site conditions with a greater degree of accuracy than previously, providing the basis of more informed design, modeling, and decision making.
But what exactly is point cloud scanning, and why is it gaining so much momentum?
It is time to get down to the nitty-gritty of this technology and how it is used, what place we can devote to it in the project time frame, and what one must keep in mind prior to the introduction of this technology into the project.
What Is Point Cloud Scanning?
Point cloud scanning is laser-scanning hundreds of millions—even billions—of three-dimensional points. The points are surfaces of objects or space, from walls and ceilings to pipes, equipment, and terrain. The points are then a "point cloud" together after they are scanned—a spatially accurate 3D model of what was scanned.
Whether sweeping a factory, bridge, tunnel, or ancient monument, the principle is always the same: transform reality into numeric information. The equipment itself is most often a point cloud laser scanner, emitting blasts of light (LiDAR) that bounce off surfaces. The scanner calculates distance by how long it takes for the light to return, to the millimeter.
From Scan to Model: The Potential of Point Cloud Modeling
Even though the point cloud itself is spatially very dense, raw scan data isn't necessarily user-friendly. This is where modeling point clouds becomes important.
For instance, a plant operator could use point cloud modeling to create an encyclopedic as-built image of his or her plant. From there, the operator can plan upgrades to equipment without needing to cease operations or estimate clearances.
Architects and engineers can likewise use the information to build off existing surfaces or structures, minimizing field errors and misalignments.
Why Laser Point Cloud Scanning Is Revolutionizing AEC
This is why increasing numbers of professionals within the AEC (Architecture, Engineering, and Construction) and industrial communities are using laser point cloud scanning:
Speed and accuracy: Scanning an entire building is now a matter of hours, not days, and to sub-centimeter precision.
Non-intrusive: Disrupt or alter on-site work no longer. Quick and quiet scanning.
Data completeness: Every nook and cranny within a building is recorded—including items that traditional surveys may miss.
Better planning and design: Point cloud models avoid the guessing and reworking later in a project.
And with firms like 3Deling offering pro-grade scanning and modeling capabilities, it's never easier to bring this capability to your organization without spending a fortune on specialized equipment or training staff in-house.
Common Applications of Point Cloud Technology
Construction & Reconstruction: Point cloud scanning is used by contractors for as-built documentation and construction quality control.
Industrial Facilities: Energy plants and facilities use the technology to monitor piping, equipment, ductwork, and safe zones.
Historic Preservation: Restorations can be planned by conservators using high-resolution scans of buildings to conserve sensitive buildings.
Property Management: The detailed models created through high-resolution scans assist managers of the buildings to keep the properties in good health condition and schedule them as well as monitor their transformation over a given period.
Infrastructure Scanning: Tunnels, bridges, and rails are safe to scan and document because they are easily scanned without much interference.
Challenges and What to Expect
Point cloud laser scanners produce wonderful results, but not all scanning jobs are the same. Areas of heavy shadow, reflective areas, or pointy corners might need more than one scan or special equipment. Experience is where that comes in.
With the help of a professional service provider, it is guaranteed that proper techniques are applied—scan registration to post-processing—and generated data is clean, aligned, and accurate.
Secondly, processing big point cloud files would become a hassle if not with suitable hardware or software. It is another reason why clients would like to outsource scanning and modeling firms they have a trust relationship with, rather than bringing it in-house.
