Building data collection or commonly called as building data capture is a process where relevant information collected from the building. Throughout the years, the method to capture data has evolved to become a more sophisticated yet friendly user to collect accurate information from a building.
Commonly, many are still using the conventional method such as measuring tape or measuring laser for site measurement. Such a conventional method is practically used in the building industry, however the time consumption is longer, and inaccurate data may be produced due to human errors and some unforeseen issues. Thus, IPM Professional Services provide 3D scanning services to our client. With 3D data scanning by IPM, the time consumed to collect data are much lesser and much accurate information can be produced.
Three methods in capturing data:
- Laser Scanning – uses laser and best used to capture data for external building. With the radius to capture data as far as 130 meters, laser scanning can help in getting enough information from a building in a short time.
- 3D Photogrammetric Camera – best used for internal data capture due to its smaller size and easy to move. The coverage radius can be up to 8 meters radius with the accuracy of millimeter.
- Drone – normally reaches an area that can’t be reached using laser scanning. For a building with more than 130 meters height, the drone would provide the best solution in getting relevant data at the height of 130 meters and above.
Once the data is captured, the images will be uploaded in the cloud, where every point of data will be stitched perfectly. We can later use to create a 3D model, digital twin, monitor work progress, capture crime scene, plan for maintenance, assets tagging, and many more. The files are user friendly easy access by using a handphone without the need to download any special apps, and can be used as VR walkthrough.
Benefits and usage of 3D scanning:
- Conservator of a historic building can walk through the building in its original condition, entering every room as we are there. Known for its complex detailing, the arts of a traditional historic building can be preserved and digitalized for future reference.
- Currently, there are some of the buildings were occupied without obtaining a Certificate of Completion & Compliance (CCC) or Certificate of Fitness for Occupation (CFO). And there are cases where the construction drawings for the building are not archived. Therefore accurate data capture is required to produce as-built drawing before the issuance of CCC can be done.
- Projects under construction would be benefited from this technology especially when the Clients or Consultants need to verify the progress at the site or to confirm the changes and evaluate its value, build quality and delivery.
In a nutshell, 3D data capture is useful and an upcoming trend. By capturing a lot of building data, it helps restoration projects, and designers can better visualise their designs using real-world building data as a foundation. This will change how professionals deliver tasks in the near future and IPM is moving towards a digital future!
