Reality Capture for As-Built Documentation: Best Practices

Feb 15 2023

11:00 AM - 12:30 PM MT

Room 708

When working with existing buildings and infrastructure, there are rarely complete and accurate documents that can be relied upon for renovation or construction. Digitizing as-built structures can provide an accurate, accessible snapshot of an asset, allowing project managers and other stakeholders to have a starting point for future work. As reality capture technologies have continued to evolve, so too have the workflows for capturing as-built documentation, including workflows that accelerate the pathway from 3D scans to BIM, floorplans, or other construction-ready formats. This session will highlight innovative projects and workflows that are bringing as-built scans to new heights.

Plan, Scan, & Deliver: Best Practices for Large Reality Capture Projects

With the increased use of High Definition Laser Scanning (HDLS) and other Reality Capture methods for documentation, it has become common to need to Laser Scan large buildings, sites, or complexes. These larger-scale projects can take several days, weeks, or even repeated trips over months or years. At Hale TiP, we have started working on multiple large-scale projects per month and developed many techniques for capturing the data as efficiently as possible, as well as registering the data and producing deliverables. We also combine Terrestrial Laser Scanning, Mobile (SLAM) Laser Scanning, 360┬░ Photo Documentation, and UAS Photography & Photogrammetry to improve efficiency and understanding while delivering a superior product. At Hale TiP we use FARO and NavVis laser scanners and software, however, these techniques can be applied to any hardware and software. In this session, we will explore techniques for efficiently using a variety of reality capture methods to document a project and produce a point cloud deliverable. These techniques will include strategies for planning data collection; documenting work completed in the field and in the office; organizing your scan data; registration, cleaning, and exporting of your point cloud; and more.

Reality Capture for Owners – An Independent Evaluation

Reality capture technology has rapidly evolved in the past two decades and continues to be in a state of accelerate change. Gafcon Digital Senior Project Integrator John Niles works with building owners who are looking to transform their projects, but who are constantly losing track of this evolving field. He is the primary author of Digital Twin Consortium whitepaper, "Reality Capture: A Digital Twin Foundation," which begins to demystify the principles that make reality capture successful. This presentation will guide users on which reality capture tools and techniques should be deployed, when they should be deployed and how to integrate reality capture into their strategy. He will take use cases from his recent work on an office campus improvement project where several reality capture technologies were evaluated at different points in the lifecycle of the project. His final report evaluated the strengths and weaknesses of each application and where it was used within the project. His vendor-agnostic position makes him an impartial reviewer to the space, helping owners select the best fit for their needs. For John Niles, the use case drives the decision, not the vendor marketing material.

Seattle Sound Transit and Laser Scanning for As-Built Verification

Working to create the perfect as-built has become much easier with the advent of so many reality capture technologies. We found that one benefit of deploying a laser scanner to a job site was the ability to capture the site at various phases and then overlay them to create an x-ray effect. We deployed this method for a parking garage built for Seattle Sound Transit to service their new light rail extension. This was to create a digital twin that would help reduce re-work, specifically by locating post tension cables in the slab deck so that future installers and cutters wouldn't snap any cables or hit and damage any rebar. The ROI on this project has been immense and includes the additional ability to distribute our models to our stakeholders through ACC and Cintoo.
