The Scan to BIM Process has helped enhance the productivity of AEC professionals with the creation of smart 3D building models where each design element is clearly defined. The application of Scan to BIM Modeling can be seen in as-built documentation, project renovations, additions, and even facility management. The models are also valuable for comparing original building plans, topographical registration, and more.
A 3D Scan to BIM model benefits all stakeholders throughout the lifecycle of a project. Here are some best practices that ensure an efficient Scan to BIM process:
Identifying the intention of the Scan to BIM model is crucial for its success. You need to outline the results you expect to achieve with the model — Do you want it to reflect the existing structure of the building? Is the BIM model required for the MEP trades? Determining the stage of the project where the model will be used acts as a solid starting point for the process. Requesting a LOD 350 model can enable project managers greater control and coordination between all the industry’s professionals to get the project rolling.
If you provide 3D Laser Scanning Services for the process, defining the project's scope will help identify what you want to achieve with the Scan to BIM Process and communicate the scope of work effectively to the client. Creating a checklist that includes answers to important questions can speed up the planning phase. • What Level of Detail (LOD) and Level of Information (LOI) are required for the model? • What specific parts need to be modeled? MEP? Trussing systems? • What is the purpose of the model in the project? • When is the model required?
Since the result of a Scan to BIM can be used for various purposes, you should understand the client's requirements regarding how they want the results to be delivered. Do they need a particular LOD and LOI's structural, architectural, and MEP Revit files? Depending on how the client aims to use the results, they may require different file formats.
It is better to gather additional information and then discard data that isn't required instead of collecting limited information. Returning to collect missing data can prove costly and time-consuming; therefore, it's important to collect all the needed information the first time.
