The Lifecycle of a 3D Heavy Civil Construction Model (Reloaded)

As the horizontal construction world continues to catch up with the all-encompassing contractors, we will once again dive into the use of 3D heavy civil construction models and the workflow associated with them. We will cover the benefits of using a 3D model, starting at the bid and going through construction and lastly as-builts. Shown through the eyes of a contractor, we will share both field and office experiences while displaying project examples. We will discuss creating models for bidding, procuring field data to support 3D models (including unmanned aerial vehicles and laser scanning), using AutoCAD Civil 3D software to build excavation models for quantification and automated machine guidance, modeling to determine means and methods, utilizing the 3D model in the field for stake less layout, and using clash in Navisworks software. We will also cover virtual design coordination with owners and subcontractors, decreased turnaround time on requests for information / change orders, safety benefits, point clouds, and fabrication plans.
