A world-renowned destination and the most visited paid public garden in America, Longwood Gardens includes 1,000 acres of botanical gardens and receives more than 1 million visitors annually. When Pennoni was retained to provide survey, geotechnical, and civil works for a new 1,200-car overflow parking lot, they needed to identify a suitable and cost-efficient location on the property amid a tight timeline. They realized that their previous civil design software would take too long to provide grading and cost estimates to the client. Therefore, they needed an open, comprehensive civil technology solution.

They selected OpenSite SITEOPS to perform conceptual modeling and calculate cuts, fills, and costs. Working in an integrated platform, they shared project information in real-time, saving two to three weeks in design time. Bentley’s application reduced overall delivery time by 50% and conceptual engineering time by 25%. They used the 3D models to create an integrated digital twin that will help design future expansions.
