Part of the Tampa Hillsborough Expressway Authority’s project development and environmental study of the East Selmon Expressway, WGI was tasked with performing a design survey for widening a nine-mile highway section. The complex roadway features a four-lane limited access highway and a three-lane raised toll expressway, 46 bridges, and 34 ramps, making it challenging to survey. WGI needed an integrated technology solution to survey and process multisourced captured data into a 3D digital model to share with the client.

They selected MicroStation and Orbit 3DM to integrate and merge the point clouds into a 3D model and create a digital database. Using Bentley’s integrated applications provided a unified environment to combine feature extracted data from MicroStation with data from different LiDAR technology to generate a digital twin accessible to the client. The digital solution reduced staff survey time on site during COVID-19, improving safety and reducing labor costs associated with site visits.
