3D Design

Three-dimensional models are intended to provide a comprehensive representation of a project both during design and construction phases.

Why use 3D?

According to the Federal Highway Administration, the use of digital data reference packages is anticipated to yield construction savings of approximately 6 percent and a time savings of 30-40 percent.

On most construction projects, the Oregon Department of Transportation now requires delivery of a digital data bidding reference package.
