Building Information Modeling


How do BIM and Scan to BIM correlate?
Building Information Modeling is the process of creating digital representations of the functional and physical characteristics of spaces and facilities. BIM is important to the AEC industry as it allows businesses to approach projects with a higher level of insight and predictability.
When there is a project involving a pre-existing site, reality capture of the as-built environment and surroundings helps provide a designer and architect with the most crucial information about the model.
Thus, scan-to-BIM can be defined as digitally capturing a physical space or facility as 3D laser scan data, which aids in the early creation and boosts the development and maintenance of a virtual BIM model.
Is 3D laser scanning only meant for the conservation of historical monuments and renovations?
The answer is certainly no…3D Laser Scanning can also be used for new construction projects. It assists the engineers to survey the site, make a model and incorporate the necessary changes if required before the development phase initiates. In case of existing projects it can be used to create a record of the environment and adjacent buildings and structures before demolition. Thus, Laser scanning can be deployed in a new construction project to facilitate the BIM process.
The 3D laser scanner can capture the exterior as well as the interior edifice, which can also comprise of concealed mechanical, electrical, plumbing, and fire protection installations. Thus scanning such installed components can provide a precise documentation of pipes, HVAC, structural steel, floors, and rebar in the concrete slabs throughout the entire building.
What are the benefits of 3D Laser Scanning?
- Quick and qualitative collection of data: It is the quickest method, as laser scanners can collect millions of data points in seconds, reducing the delay and human resources needed to carry out surveys.
- Maximizes efficiency: It reduces a large degree of human error by eliminating human involvement in scanning and thus maximizes efficiency.
- Reduces health and safety hazards associated with surveying inaccessible areas: Surveyors can stay safe by using laser scanners to collect information from dangerous or hard-to-reach locations without putting themselves at risk. Laser scanners also aid in collecting point cloud data from inaccessible areas that were once off-limits.
- Detailed 3D Models Can Be Created from Scan Data: The biggest advantage of laser scanning is that the scanned data can create 3D BIM models on which further analysis, simulation, walk-throughs, etc. could be done.
- Accelerates decision-making: It facilitates faster decision-making and project alterations; there is improved transparency, collaboration, and effective communication amongst stakeholders and team members.
- Reduces unnecessary costs and rework: Reducing rework can reduce the construction cost as well as help maintain the timeline of the projects. Knowing which materials are needed and determining their actual costs could lead to significant savings.
Thus, 3D laser scanning can add great value to the BIM process. This is proving popular in the AEC industry. Moreover, the extensive use of point cloud technology by AEC professionals is helping them optimize the BIM process and achieve great results. That’s why the application of 3D laser scanning to BIM is sensible.
