Visicon used to compare as-built with design data

Visicon is being used to merge 3D scan data of post-tensioned slabs with the design BIM models. The scan data that is taken right before concrete is cast is cleaned to only show post-tensioning and electrical conduits. The cleaned point cloud file is then merged with the federated BIM model in Visicon to create the as-built record for the project.

The Visicon model with embedded scan data will be used by the owner for future facility maintenance support and location of tendons and conduit in the slab. The general contractor, engineer and specialty PT supplier are using the data to better understand and calibrate how as-built conditions vary from what is shown on shop drawings. The ultimate goal is to improve the shop drawing process to better predict how installation will happen on the site.
