When building large multi-story structures there will be numerous structural concrete pours spread over multiple months of time. 3D scanning can be implemented throughout this process to capture the existing rebar plan and sleeves, post-tensioning and conduit before the concrete is poured. This allows the project manager to check the existing conditions for any irregularities and correct them. With tight deadlines, construction managers cannot afford stalled construction or the issues that arise due to critical errors that were undiscovered cropping up down the line. 3D scanning allows you to quickly and accurately ensure everything is in the right place the first time. To enable this, 3D scan data must be aligned to the existing design drawings in a short timeframe that allows checks to be made without delays in the site schedule.
With scanning on a job site multiple times per week, over the length of the build, 3D scans provide up-to-date snapshots of site status. Scanning can be performed on an active site, without delays or work stoppages. Engineering resources can quickly deliver ‘stitched’ point clouds that have been correctly aligned to existing building plans for construction management to review and approve. Millimeter-accurate point-cloud data enables a detailed site analysis to be conducted and for the identification of any changes that must occur before the concrete is poured. Colorized and ‘intensity mapped’ point clouds can also be created for various engineering needs and for general ease of use.
For as-built documentation, existing condition drawings or reality capture, 3D laser scanning is the fastest, most accurate, most efficient option. 3D laser scanning for project analysis and project risk management delivers tens of thousands of dollars worth of savings if only a single issue is detected. An issue with conduit or sleeve alignment, or other issues discovered only after concrete is poured, can pose serious issues and extensive costs. A scanning partner with experience and skill makes 3D scanning a versatile and valuable tool. 3D scanning is quick and accurate, providing project insight and risk management that helps ensure projects are completed on-budget and on-time. Whether it’s new construction, renovation or retrofit projects, 3D scanning provides architects, engineers, BIM managers, general contractors, and construction managers with the information and insight to fix issues and make critical decisions before they cost time or money.
