SCAN TO BIM CHECKLIST

Scan to BIM Services

Do you wish to create an as-built 3D BIM model of your existing building? Are you interested in restoring your historical building to its former glory? Do you want to monitor how your building project is progressing on a daily basis? Scan to BIM is the solution for all these questions. surveyors, property owners, architects, engineers, and general contractors how to use 3D laser scanning in construction to create point cloud models for 3D BIM models. A Scan to BIM checklist is a necessity for an efficient Scan to BIM workflow.

Let us understand how the process of Scan to BIM services functions and why a Scan to BIM Checklist 📝 is important.

What is Scan to BIM?

Scan to BIM is the practice of constructing a digital representation of the building’s physical and functional attributes in BIM. Accurate as-built models can be created using a laser scanner, which is then integrated into 3D BIM software like Revit to represent the design in a real-world context.

For 3D BIM model development, 3D visualization, animation, and quality inspection, several construction projects in the renovation and extension stages are utilizing the point cloud Scan to BIM method. Surveyors, owners, architects, engineers, and general contractors all use laser Scan to BIM best practices for their repair and refurbishment projects in the AEC sector.

Why a Scan to BIM Checklist?

The Scan to BIM checklist is nothing more than a tool that will assist you in creating an organized process, helping you to maintain repetitious activities, fostering a good design habit within the project team, and assisting team members in memorizing task sequences in a process, among other things. Renovation, refurbishment, retrofit, and reconstruction projects can all benefit from using this checklist as a guide.

For your convenience, we have provided you with a simplified Scan to BIM checklist that you can use to streamline your Scan to BIM workflow. Depending on your project, the Scan to BIM checklist may alter slightly from the sample below. Always remember not to passively follow someone else’s Scan to BIM checklist, and to tailor your Scan to BIM workflow to the specifics of your project rather than the other way around.

Scan to BIM Process Stages

The entire Scan to BIM process can be divided into four stages:

  1. Identification of Requirements
  2. Scan Planning
  3. Point Cloud Scanning
  4. Deciphering the Point Cloud Data
  5. BIM Modeling
  6. Quality Control

Let’s take a closer look at the entire Scan to BIM process and what goes on behind the scenes before we get our As-built model.

Scan to BIM Workflow Framework

Scan to BIM Checklist -Tejjy Inc

🟢Identification of Requirements

If you are planning on using Scan to BIM, you will need to define exactly what your scope of work (SOW) is and how you are going to use the 3D BIM model. In order to ensure that your as-built BIM model is as accurate as possible for the intended usage, it is critical that you choose the level of detail (LOD) 100 – 500 for your model. In this stage, we identify the following information:

  • Define and document the scope of work (SOW)
  • Agree on the Level of Detail (LOD)
  • Agree on the deliverable formats
  • Agree on the QC process
  • Confirm the intended use of the model

🟢 Scan Planning

Prior to doing a 3D scan, parameters are determined through scan planning such as the Level of Accuracy as mentioned in the U.S. Institute of Building Documentation (USIBD). Coverage and selection of optimal locations are crucial aspects of scan planning.

  • Select the appropriate device
  • Get a qualified operator
  • Select the optimal locations
  • Define the Level of Accuracy required

🟢 Point Cloud Scanning

A ‘point’ represents the location of this surface in relation to the 3D laser scanner. A point cloud is a result of combining all of these points into a single, highly accurate image. Using popular laser scanning instruments like Faro, Trimble, Riegl, and Leica, multiple point cloud scans are used to produce an accurate digital image of a building. The point cloud scan provides a comprehensive perspective of the structure, ensuring that the representation is accurate.

  • Do on-site verification and inspection
  • Geo image referencing
  • Capture the point cloud data

🟢 Deciphering the Point Cloud Data

Point clouds from the building’s scan are fed into scan to BIM software like Autodesk ReCap at this stage. A point cloud or mesh is generated in support of BIM processes using laser scans and images imported into ReCap by collaboration across teams using real-world data which is then enabled to support a wide range of use cases in the AEC industry.

  • Define Point cloud scan file format
  • Define coordinates
  • Verify grids alignment
  • Verify levels alignment
  • Verify model alignment

🟢 BIM Modeling

In 3D BIM modeling, a real-world point cloud data is transformed into a digital representation of the project. The Point Cloud Scan needs to be modeled in a series of processes, starting with the verification of the point cloud scan and file insertion in Revit. Using the point cloud scan data, an as-built 3D BIM model is created which can be used for the renovation, refurbishment, retrofit, and reconstruction of the building.

  • Set the project north
  • Assign a view template
  • Establish the working views
  • Follow file naming convention as per BEP
  • Verify the Common Data Environment (CDE)
  • Follow the worksets naming Convention
  • Create the Revit BIM model
  • Append the Revit model
  • Verify correct coordinates
  • Generate viewpoints
  • Update the Revit BIM model

Companies that provide widely used scanning tools are Leica, Faro, RieglTrimble, etc.

🟢 Quality Control

Scan to BIM Revit plugins are used to verify project standards when they are being checked. When checking the quality of a 3D BIM model, a scan to BIM checklist is used. Revit section views can be used to check for any deviations in the design. In this way, MEP clash detection and coordination between trades are simplified and can be used to measure discrepancies.

  • Eliminate errors, and clash issues
  • Assure that all standards are followed
  • Ensure enough geometric elements, the correct position, and functionality
  • Confirm if the client’s requirements are met
  • Delete unnecessary views and plans
  • Delete unnecessary groups
  • Verify worksets
  • Purge file
  • Audit file

📌 Advantages of Scan to BIM

Key benefits of Scan to BIM are:

  1. The BIM model created from the scan data allows for greater reliability and quality assurance than the one created using traditional methods.
  2. By using scan data to create a virtual BIM model, it is possible to avoid costly mistakes during construction.
  3. Better transparency, communication, and collaboration are all made possible by Scan to BIM process.
  4. By helping in creating a BIM model, this process will assist the client in making decisions regarding the design of the structure.
  5. The risk related to faulty design can be reduced.

Conclusion

The process of importing and calibrating raw scan data before it is ready to be used by a project team requires a high level of technical knowledge and expertise. It is extremely beneficial to have a highly accurate three-dimensional digital model of your structure or site available. By using a checklist for this Scan to BIM workflow, you are now better prepared to develop your design or restoration proposals, scope out your construction projects, or check on the status of existing construction projects.
