Point Cloud to BIM Renovation and Retrofitting

 

The Point Cloud to BIM technology is rapidly gaining traction and widespread acceptance in the AEC sector. Point cloud data collection and conversion into BIM for renovation and retrofitting projects, facility management, major repair projects, accident recreation for forensic investigations, and many more are among the technology's many applications. Point Cloud to BIM is also known as Scan to BIM due to the fact that when buildings are surveyed with a 3D laser scanner, the data is collected in the form of a point cloud—a cluster of millions of points in a 3D space—and this method is also known as Point Cloud to BIM. Experts turn these point clouds into 3D models that are ready for BIM by importing them into software like Revit.

How does this Point Cloud to BIM technology work?

• The defined area is the subject of a 3D laser survey. Point cloud data of interior, exterior, and landscapes can also be gathered. Experts conduct a greater number of scans and precisely cover every detail when the complexity of the structures and details to be covered increases.
•  The point cloud data acquired is in a 3D format, hence apt for visualization.  The 3D point cloud models are exported into Revit software using additional programs like Lecia's Cyclone.
•  Point cloud data can be imported into Revit in a variety of formats like PTG, PCG, and PTS.
• Using a variety of options in Revit, experts can break up a large data file into smaller ones for easier viewing.
• Photometric images, in addition to the point cloud data, can be used to gain a deeper comprehension of the structure and enable BIM specialists to produce 3D BIM with the utmost precision.
• BIM professionals trace on to the point cloud models using both photometric images and point cloud models using a method called surface restructuring.
• A model of a point cloud is a three-dimensional structure made up of millions of points. Retracing on to these models, experts create a 3D model with nurbs, triangles and polygons.  For project management, these models can be loaded with building information.

Benefits of Point Cloud Scan to BIM

• Scan to BIM enhances collaboration, transparency, and communication.
•  The scan data-based BIM model provides greater reliability and quality assurance.
• Reduces the cost of construction
• Scan to BIM facilitates project modifications and accelerates decision-making.
• Better project sustainability results from using BIM throughout the construction process.
• By virtually creating a BIM model from scan data, construction errors can be avoided.

Utilizing highly efficient laser scanners, building data are extracted during the scanning process. When laser beams get back the hardware and they were directed towards the structure in the beginning, point clouds are acquired.

Why has Point Cloud to BIM gained popularity?

BIM is mainly used for new built project; however, retrofits need a different approach.  Point cloud survey and conversion into BIM is this approach, and it supports detailed collection of structural data and an accurate representation of an ‘As built environment’.  Scan-to-BIM has also gained popularity as the renovation and refurbishment market has expanded, and every major developer supports this technology.

Rightservve have established a global presence with its multidisciplinary outsourcing service portfolio.  The company has developed expertise in converting Point cloud models from scanned survey data into BIM, and it is able to efficiently supply the clients with the level of detail they require.
