For decades, transportation agencies and contractors have relied on 2D plan sheets and standard cross sections during design. In the April/May issue of ARTBA’s Transportation Builder magazine, Jeff Bachiochi, PE; Aaron Guette, PE; and Ryan Noyes, PE, share how VHB partners with clients like the Vermont Agency of Transportation (VTrans) to transform this legacy approach through data-driven, model-based design (MBD) and digital delivery.
Highlighting two recent projects—the I-89 Exit 17 Interchange reconstruction in Colchester and the Chester Town Highway Bridge—the feature explores how an integrated 3D model paired with traditional plans on one project, and a fully model-based legal contract document on the other, improved clarity, collaboration, and constructability.
