A Million Points of Light: The Benefits of 3D Laser Scanning - Jobsite by Procore. A Million Points of Light: The Benefits of 3D Laser Scanning Share on facebook Facebook Share on google Google+ Share on twitter Twitter Share on linkedin LinkedIn In the competitive construction world, time is money. The scanner works by putting out millions of lasers to create highly accurate 3D renderings of a space, whether it’s a building under construction or even during the preconstruction phase.
This captures and creates millions of data points in just a few seconds that can be continually measured and compared against as the project progresses. The sum total of these measurements comprise what is known as a “point cloud,” a dense group of 3D points that recreates a physical object in digital space. This is especially useful in a complex, unfinished interior structure with the work of multiple trades simultaneously underway, or in a job involving retrofits or refurbishment.
Once a scan is complete, the resulting data is collected and processed for model generation. More to explore Search. Why brownfield projects should use 3d laser scanner? As-built documentation is crucial to the development of brownfield projects. But the challenge for existing/brownfield assets is the ability to turn decades’ worth of operational information and experience from various sources and systems into ‘applicable information’. As-built documents are often incomplete, or outdated and hence unreliable.
Currency and accuracy of data is critical in the design environment. The success of the design depends on the original source data. Revamps require time-intensive remodeling, leading to several design iterations and back and forth. The gathering and verification of as-built documents can take up to several months and require several site visits – adding up to the cost of the project and causing unnecessary delays. Laser survey data produces “point cloud” that comprise millions of points and is the most accurate information and assessment tool for engineers and designers. Benefits of 3D Scanning for such projects 3D Modeling and As-built data.
Untitled. 3D Laser Scanning Technology Benefits Pipeline Design | Pipeline & Gas Journal. The prolific Greek mathematician and geographer Eratosthenes came to understand that the world wasn’t flat when he calculated the circumference of the earth in the third century BC. Portuguese explorer, Ferdinand Magellan – 1,800 years later – again reminded us that the earth was not flat when his fleet successfully circumnavigated the globe in 1522 AD.
Awareness that the earth is not flat has existed for centuries, yet we continue to constrain our engineering design efforts to two dimensions. The world consists of three dimensions and we have reached a point where engineering, design and planning should follow suit. 3D Laser Scanning provides a highly accessib Log in to view this article.

Adoption of 3D laser scanning proves beneficial for construction surveying. Abstract: One of the greatest challenges that a contractor or a project owner is likely to face during the execution of industrial, commercial or any other construction project is surveying the large area of construction site.
Industrial and civil construction projects often involve surveying of a very large and intricate site area, using traditional surveying methods that are both time consuming and cost ineffective. As a result, the completion of such capital construction projects tends to face significant delays even before the actual construction starts. In order to complete the construction projects on schedule, project owners and construction contractors can take advantage of the latest technology advancements in land surveying. One of the fastest growing technologies in surveying space is the 3D laser scanning.
The construction industry has been slow in adopting new technologies and had not undergone any major transformation over the last 40 years. What is 3D laser Scanning? Constructible.trimble. If you’re a contractor looking to step up your tech game in the highly-competitive construction industry, 3D laser scanning could be the next logical step towards making your jobs more efficient— saving you time and money. How Does It Work? 3D laser scanning emits millions of laser lights and by timing their return, can accurately and precisely calculate their 3D locations, to produce multiple high-speed scans, brought together into one system. It works by digitally capturing the dimensions and spatial relationships of objects using the reflection of a laser light.
The technology has a wide array of jobsite applications, including: Pre-construction as-builts Building Information Modeling (BIM) Virtual Design Construction (VDC) Quality Control during construction Comparing design intent to as-built conditions Point cloud data goes into a common reference system where it’s merged into a complete model. Why Would You Need It? 3D laser scanning is quickly becoming the norm in the AEC industry.
