Lifecycle of a 3D Heavy Civil Construction Model from the Office to the Field and Back

The presentation will cover the use of 3D models on a construction site and the workflow that starts at bidding and goes through construction and final as-builts, all from the perspective of a contractor. Professional presenters will share both field and office experiences while displaying project examples. They will discuss importing PDFs, importing CAD files for bidding, using contractor surveying to support 3D models, using AutoCAD Civil 3D software to build excavation models for quantification and automated machine guidance (AMG), modeling to determine means and methods, using the model for collaborative design with owners and subcontractors, using AMG for increased safety, and utilizing the 3D model in the field for layout and the collection of additional as-built data. Other areas we will cover include using clash in Navisworks project review software, decreasing turnaround time on change orders and requests for information, gaining safety benefits, developing fabrication plans from the models, and performing stockpile modeling using an unmanned aerial vehicle.
