"Contactless Capturing" is a term frequently used to highlight the benefits of as-built 3D scanning. This method proves especially valuable in accessing challenging areas like crawlspaces, attic spaces, high ceiling details, facades, and roof information through laser-based capture. In essence, the lasers emitted by a 3D scanner can reach areas of a building that field technicians physically cannot, at least not as safely and effectively. The results are not approximate either, as they may be with hand-drawn field measurements; rather, they are nearly exact. Most professional-grade 3D scanners boast between 1/8”-1/2” accuracy. This becomes particularly helpful when tasked with documenting the existing conditions of older buildings containing numerous hard-to-access locations.
Consider the example of a crawlspace as exemplified in the accompanying video: the utilization of 3D scanning technology eliminates the need for scan technicians to physically crawl into tight spaces to capture nonetheless-critical details like ductwork and piping. Let’s face it, crawlspaces can be unpleasant – tight, dimly lit, prone to pests, and potentially hazardous. Minimizing the time spent capturing MEP-related components is a clear advantage. Additionally, 3D scanners can faithfully capture the unique geometry that makes up typical dirt crawlspaces, which would be otherwise challenging to plot due to their nonuniform and earthen foundations.
How does this benefit our clients? Visualizing a building’s inner workings in 3D provides insights into the spatial relationships between various components, such as pipes, ducts, and wiring. This helps identify potential clashes, interferences, or inefficient routing, which can be addressed before construction or renovation, reducing rework and delays. The non-contact nature of 3D scanning makes it a powerful and practical solution for capturing accurate and detailed measurements of buildings, enabling architects, engineers, and construction professionals to work with precise and holistic data.
