Point cloud to BIM – A collaborative approach in the Virtual Construction World

Point cloud to BIM – A collaborative approach in the Virtual Construction World

Scan to BIM Modelling is the latest discovery in the construction industry. Measuring firms, Survey companies, Architectural and Engineering firms etc. are shifting over from traditional survey methods to an automated scan method. Once the existing building or site is scanned, the scan images are registered and then converted to .rcp or .rcs files prior to converting them into Revit or any other 3d format. This technology has more or less eased a lot of other strenuous efforts of multiple technicians visiting the site for manual measurements or surveying.

Laser Scanner

Quite a few design constraints, planning issues or other an onsite problems have been eliminated due to this cutting edge technology i.e. scan to BIM Modeling. It is important to deploy right tools and resources to achieve high-quality results and quick turnaround time. As built projects or developing 3D Revit model from laser scans have become less effortless after the advent of scan to BIM modeling services.

Let’s take a sneak peek at how Scan to BIM Modeling works and how technical experts or construction industry people use the technology to execute Asbuilt or renovation projects. It is a great revelation in the virtual construction field to see the combination of Building Information Modeling and Laser scan technology restructuring the entire renovation and restoration field. Revit is widely used and is instrumental in making Scan to BIM Modeling one of the most used technologies.

How can this technology be utilized to the maximum?

– As built 3D models or 2D drawing creation from scan up to LOD 400 or LOD 500

– Detailed 3D, 4D and 5D BIM Models from point cloud

– Renovating historical structures, existing old Government buildings, refurbishment or design amendments of existing buildings

– Develop 3D renderings, Animation or Walkthroughs to present existing and proposed building structures from laser scans

– 2D Architectural construction drawings from scan images

With the high-end involvement of Revit, the entire point cloud to BIM process is known as “Revit Scan to BIM Modeling Services”. This technology is currently provided by many AEC and BIM companies in India that too with high precision and quality. Laser scanning ensures a high level of penetration into the building and ability to gather all the Architectural, Structural and MEP components however deep and detailed it is. This absolutely simplifies the process of as built modeling and saves time in a real sense.

Technicians performing scanning usually start by placing the scanning equipment at a different angle to capture building images. These scans later emit laser rays on the building which becomes instrumental in scanning the building from all sides with complete penetration. The data which is extracted is in raw format and needs to be cleaned up first prior to sending it for conversion in 3D. One point that is worth pondering is the file size of the scan images or data. They usually are in GB’s. Any company working on scan to BIM Modeling projects needs to have technically advanced and robust infrastructure, to accommodate the data size. High-speed computer and the internet is the primary requirement to efficiently execute Point cloud to 3D Revit Modeling projects.

Laser scan images usually is not a single file. It is a conglomerate of multiple files that are put together and provided to the Architects and Engineers to work on. Once these are converted and sent in.RCP .RCS or.PTS formats they are then opened in a software that supports laser scans. Usually, Revit software supports point cloud data and hence it is instrumental in developing Architectural Construction Drawings or 3D Revit models from scan data.

Developing 3D Models from scans, Point cloud to MEP BIM modeling and creating Architectural visualizations from point cloud data is not a cake walk. It takes plenty of technical experience, expertise in understanding international standards and codes along with years of experience in Revit BIM Modeling. However, in the current scenario, there are plenty of Scan to BIM companies in India who assist in developing 3D Revit Models from point cloud files. These companies have a huge client base who are in need of availing scan to BIM services in UK, USA, Canada, Australia and Europe. You can visit www.cadservicesindia.com, which is one of the leading AEC and pre construction BIM Company in India offering high precision and accurate point cloud to BIM services to international clients.
