Accuracy is crucial when conducting a site survey, tracking the status of construction building models, performing BIM clash detection services, and examining a site as a whole or just specific features. Site surveys have significantly advanced from hand-recorded measurements.
Human error is always possible when taking measures by hand, which is why 3D laser scanning has become so popular recently. With 3D laser technology, you can quickly and effectively gather a point cloud of data with high precision for various applications. Scan-to-plan and scan-to-BIM, popular uses for cloud point data, begin with documentation by full 3D laser scanners.
The key distinction between the two is what happens to the data after the scanner has recorded it. How do you choose the best procedure for your project, and how does each one operate?
What is Scan to Plan?
As previously said, the scan-to-plan process starts with an on-site scan that provides precise information about the building down to a few millimeters. Millions of data points are left behind, and when combined, they can produce a picture of actual as-built circumstances. This point cloud can serve as the foundation for extracting 2D CAD drawings after they have been gathered and processed.
Since drawings are based on exact point cloud data, which serves as the basis for the remainder of the project, Scan to Plan produces dependable deliverables. With fewer mistakes, improved teamwork, and easier access to field knowledge wherever you need it, these drawings can help you make better decisions and finish projects more quickly.
With a complete point cloud, you can zoom out to view the layout of the entire structure or delve into the details of a single room, such as window sizes and wall thickness. The ideal place to start the design process is 2D CAD deliverables with a scan-to-plan.
What is Scan to BIM?
Another step in the scan-to-BIM process is an on-site scan that gathers precise measurements of a building’s as-built conditions using a point cloud of data points. This can save architects time when modeling existing buildings for reference or planning remodeling projects. A 3D point cloud to BIM modeling makes it easier to begin the design process by creating models that let you view different building project tiers. When necessary, 2D deliverables can be produced even with the 3D model.
How do You Choose which is Better for You?
Architects, engineers, and designers benefit from both scan-to-plan and scan-to-BIM. Both can lead to increased teamwork, fewer mistakes, and lower costs on the job site long after it ends. Which one, nevertheless, is most appropriate for your project?
Require a 2D plan that is to scale? Scan to Plan
Architectural scan-to-plan choices greatly benefit scale renovations, area calculations, and space planning. This data storage technique is necessary for various planning and building processes, including permits, construction drawings, and life safety plans. It also tends to be quicker than standard 2D blueprint approvals.
Require more work to be accomplished by an architectural company? Scan to BIM
Point Cloud to BIM modeling provides unmatched insight into the as-built locations of standard fixtures, including walls, floors, roofs, doors, windows, stairs, ramps, and more. Furthermore, challenging 3D situations, such as plant rooms or above-ceiling MEP areas, are difficult to depict effectively in 2D; nevertheless, 3D modeling enables us to capture the complete picture. This is preferable for more complicated tasks, where only examining 2D images may overlook important information.
Most of the industry is moving in this direction as top architecture firms adopt a more digital approach. Using scan-to-BIM could facilitate collaboration and help businesses remain competitive.
Required to hand off to a building management team? Scan to BIM
If you plan to give the scanned data to building management after finishing the job, choose laser scanning for BIM integration. The additional context that 3D BIM scans provide—from the precise placement of amenities like ramps, elevators, and entrances to the location of covered utilities—will be invaluable to building managers when restorations, inspections, or repairs are needed.
Final Takeaway
The size and complexity of your project will ultimately determine whether you choose to scan to plan or scan to BIM. Scan to Plan provides simplicity and cost-effectiveness if you need a simple 2D depiction for remodeling or simple planning. It is the best option for more intricate, data-rich models that support lifecycle management, design optimization, and collaboration.
Both strategies offer priceless insights, but matching the solution to your project’s objectives is critical. Regardless of your requirements, using cutting-edge scanning technologies guarantees precision, effectiveness, and a strong basis for project success. Are you prepared to make a choice? Speak with professionals to choose the one that best suits your needs.
