Federal Highway AdministrationUS Transportation Collection3D engineered modeling is a relatively new and developing technology that can provide numerous bene\ufb01 ts to owners, engineers,contractors, and the general public. This manual is for highway agencies that are considering or are in the process of switchingfrom 2D plan sets to 3D engineered models in their highway construction projects. It will discuss some of the bene\ufb01 ts,applications, limitations, and implementation considerations for 3D engineered models used for survey, design, and construction.Note that is not intended to cover all eventualities in all states regarding the deployment of 3D engineered models for highwayconstruction. Rather, it describes how one state\u2014Iowa\u2014uses 3D engineered models for construction of highway projects, fromplanning and surveying through design and construction
