The deteriorating Bonner Bridge in North Carolina required near-continuous repairs for more than 50 years. Its replacement, the USD 252 million, 2.8-mile long concrete box girder Marc Basnight Bridge is designed to remain in use for 100 years. HDR had to ensure the bridge could resist hurricanes and ship strikes. They realized that a 3D modeling workflow would help them deliver bridge infrastructure with long-term performance, though they had to coordinate contributions from 250 people working across many different organizations.
Already familiar with Bentley applications, HDR relied on ProjectWise to store, manage, and share thousands of files among 250 people in different locations, and OpenBridge Designer and OpenRoads for innovative and consistent modeling. Using digital workflows, they reduced costs, design time, and coordination errors to stay on budget, ahead of schedule, and establish continued data access for use during inspection, operations, and maintenance. The new bridge provides a safe, reliable crossing and evacuation route for local residents and tourists.
