Firms offering point cloud scan to BIM conversion services provide you with a detailed and accurate representation of the existing condition of a building, especially when some alterations like retrofitting, refurbishment, renovation, or reconstruction are being planned. An effective process for performing functions like site verification, design validation, and planning, developing as-built drawings, documentation of existing building conditions, quantity take-off, and budget estimation is performed through an accurate Point Cloud scan to BIM conversion. You essentially begin with a 3D laser scan to capture the existing conditions; this scanned data consists of billions of points that are combined to form a point cloud scan. Point Cloud to BIM service providers create an as-built model, which proves very useful during the remodeling project.
The objective of performing a point cloud scan to BIM is to facilitate an effective documentation process for producing accurate and detailed drawings and documents. You would be able to obtain the following documents:
- Floor plans at all levels
- Roof plans
- Exterior elevations
- Detailed site plan
The process of Point Cloud scan to BIM conversion presents some unique challenges due to various factors. Reputed BIM providers help you overcome these challenges and create high-level BIM models to efficiently execute your renovation/retrofitting projects. Some of the possible challenges are listed below:
- Available technology often doesn’t allow you to create a BIM model automatically from Point Cloud, so you have to do it manually
- Only very simple models can be created automatically and without human intervention
- You might find it difficult to decipher elements since a point cloud may consist of billions of points
- Without the involvement of trained experts, point clouds can often be an incomplete representation of a scene
Some simple but effective steps would be required for performing Point Cloud to BIM conversion with the utmost accuracy possible, including all the critical details:
- Accurate Data Capture
It’s important to gather as much information as possible from the field and the client about the project. Clear definition of the scope of work, level of detail, and timelines for the project are required to be able to define the inclusions and exclusions for all trades.
- Processing the point cloud scan
Once you have captured the as-built conditions of the structure, processing the scan is the next step. The objective is to validate the survey data regardless of its accuracy. An accurate inspection of the scan is done to gauge the interruptions in the fluidity of the data, caused by any environmental vibration. The internal system checks sometimes don’t pick these interruptions up. The data sets then need to be broken up into clusters for scanning and retaining copies before any manipulation is made.
- BIM modeling
BIM modeling is used to give shape to the point cloud, a real-life scan of the structure, on the digital platform. One has to follow several steps for Point Cloud scan to BIM modeling, including verification of the scan, project information to file insertion, and file set up. You must use different work sets for each point cloud for efficient settings and minimize the time required to open a file.
- Process of quality assurance
Quality assurance is an essential step after the modeling to ensure the model is of good quality. Use plans, sections, or 3D views are created for a thorough comparison of a delimited area to detect clashes between electrical, mechanical, and plumbing elements by employing appropriate tools.
The process of Point Cloud scan to BIM is used for various purposes including making as-built models, especially when a renovation/retrofitting/refurbishment project is planned. Following some simple steps allows you to produce high-quality designs and execute the project efficiently and flawlessly. However, employing the services of The AEC Associates can simplify and increase the efficiency of your work manifold.
