3D Engineered Models: Schedule, Cost and Post-Production

Every Day Counts

April’s innovation of the month is 3D Engineered Models, a basic building block of today’s digital highway that allows for faster, more accurate and more efficient planning and construction.

After encouraging the adoption of 3D Engineered Models in the second round of Every Day Counts, the Federal Highway Administration is continuing to promote the technology in EDC3 to help the transportation community reap even more benefits.

In EDC-3, the focus is on three practices:

1. Using the asfound survey data from which 3D models are created for roadway inventory and asset management purposes

2. Incorporating schedule (4D) and cost (5D) information into models to enhance stakeholder communication, enable contractors to streamline construction schedules and improve cost estimates

3. Using postconstruction survey data to correct design models and create accurate asbuilt drawings that include useful details such as subsurface utilities

FHWA offers technical support and tools to help transportation professionals use 3D technology:
