Using 3D Scan Data to Help Coordination in Building Construction
The advent of 3D scanning has revolutionized the building construction industry. The ability to use 3D scans for existing and new construction allows for fast and reliable as-built verification as well as construction layout. You’ll save time, effort and money using scan data for coordination and can avoid clashes and errors by utilizing Point Cloud Data which can be made accessible to all of your engineers , Project Managers, and all other project stakeholders.
At BuildingPoint SouthEast, we have the answers you need for your most common 3D Scan Data questions and can help you unlock the power of this tool to help Building Trade Coordination.
Why and When to Use 3D Scan Data
Use 3D scan data to visualize a project in an existing space to avoid clashes and constructability issues. Quality 3D scans allow you to document and model existing conditions and verify appearance and layout before starting construction. 3D scan data is suitable for any market segment — including retail, medical, industrial and more. Use it to avoid costly change orders and time-consuming schedule extensions.
Do I Need to Model From a Scan or Can I Coordinate From Point Cloud Data?
This depends on the nature of the elements and features you’re working with as well as the quality and density of your scan data. For construction and renovation elements, such as pipes and ducts, you may need to model them to capture their full extents. In-wall and in-ceiling elements can appear as “noise” on your 3D scan, which may mean that Point Cloud Data modeling is required to clean up your data.
What Exactly Needs to be Modeled?
The detail and depth of your modeling depend on the nature of your project. In demolition, for example, hidden features that will be destroyed do not require modeling. When renovating an existing building, careful attention must be paid to those areas where you’re joining to the base structure to avoid clashes and unforeseen issues.
To save you time and money, we can help you determine what needs to be modeled and what is unnecessary.
How Accurately Does the Field Model Need to Represent the Scan Data From the Field?
As those in the construction industry know, a building isn’t perfectly straight and square like in models and drawings. Natural curvature and sag create slight bowing and arcing of many building features, such as structural beams, trusses and piping. While these may be within tolerance, they can be difficult to model. Our team can help you determine which out-of-plumb features need modeling and which ones can be left as straight and true in your model.
In the end, you need to model to the level of detail (LOD) that your project demands. At BuildingPoint SouthEast, we have the experience and equipment to help you get the most out of your scan data and allow you to coordinate existing conditions with design models. Use 3D scan data to save time and effort and focus on the critical elements of your building construction project to minimize the amount of modeling you need to do.
