In the AEC (architecture, engineering, and construction) industry, reality capture and as-built 3D models are game changers. It’s great to work from blueprints, renderings, and 3D models to create new structures. But what about when we are working with existing structures? Can we be certain that the completed project exactly matches the original plan?
This is where as-built 3D models come in. Using a process called reality capture, it is now easier than ever to create accurate, and highly detailed, 3D models of structures. Once created, these models can be used to drive renovations, retrofits, re-engineering projects, and more.
To help us better understand the benefits of 3D reality capture, let’s look more closely at the process of creating an as-built 3D model, and some potential applications.
Reality capture involves using data capturing technology tools to scan a structure, and then utilizing that captured data to create a virtual version of the structure. As Engineering.com explains it:
Prior to the invention of reality capture technology, a renovation or infrastructure project would require extensive labor hours simply to generate a reliable and accurate set of plans. That work may start with transferring original blueprints to CAD drawings and then move into site visits to hand-measure key components to verify that the project was built as spec’d.
Once every detail was manually recorded, those data points would need to be hand-entered into the CAD software, just so a 2D plan of the construction project would be built. From those plans, if the budget allowed, a 3D modeler could render a 3D model that was only as accurate as the measurements gathered on-site.
As you might expect, this process was very costly and time-consuming. And all of this would need to be done before any shop drawings could really begin.
But with reality capture, as-built 3D models can be created in a single site visit. They are accurate right out of the gate. And with the right software, the model can be available in minutes instead of weeks.
Unlike blueprints and even early 3D models, contemporary 3D models (as well as the point cloud data that helped create them) can be easily shared. Software like the JP Digital Interactive Viewer makes it easy to share your reality-captured 3D model with all members of your team in ways that were unimaginable just a few years ago. It’s almost like being able to pass around the entire structure.
As we explain elsewhere on our blog, “With geographically dispersed teams, centralizing all this data is crucial. Whether it’s original CAD designs, as-designed BIM models, build changes, maintenance records, or operational KPIs, teams can no longer afford to have information strewn about on various hard drives and paper files. Instead, collaboration should be seamless – someone needs to bring point clouds, BIM models, designs, and pertinent information into one, centralized source.”
Within the interactive software, each member of your AEC team can utilize the data and model in the ways that they need. From your engineers examining structural integrity to electricians planning the route for conduit, everyone has a model that’s scalable from macro to micro levels.
