Visualizing a Better Future

To meet the demands of new transportation infrastructure projects, many engineers are adopting building information modeling -- an integrated process for exploring a project's key physical and functional characteristics digitally, before it is built. Supplementing and sometimes replacing their traditional 2D design and drafting software with newer 3D and 4D tools for model-based design enables civil engineers to create coordinated, reliable design information. With this information engineers can respond to design changes faster, optimize projects with visualization and simulation, and produce higher-quality designs and construction documentation. This article describes how renderings, videos, and 4D simulations using a variety of software were employed in the Doyle Drive reconstruction project in San Francisco. The $1.045 billion project to replace the south access to the Golden Gate Bridge with a new Presidio Parkway required that the project team create a roadway that reduces impacts to biological, cultural, and natural resources; respects the project setting within a national park, the National Historic Landmark District, and surrounding neighborhoods; meets community needs; and provides a safer roadway. Moving to 3D and beyond for design and visualization throughout its collaborative process for the Doyle Drive replacement project allowed the project team to better understand how the design will perform; assess its impact on the surrounding area; and virtually identify and resolve issues before they become costly mistakes. The project team and stakeholders reacted positively to transparency and visibility afforded by the technology.
