The Delaware River Joint Toll Booth Commission awarded a contract to Washington Group International (WGI) for program management of E-ZPass electronic toll collection implementation at seven (7) plazas. The project included providing accurate as-built drawings (to a demanding schedule) of the existing plazas for vendors to design equipment configurations.
WGI received competing as-built proposals based on traditional surveying/drafting and based on
Cyrax® laser scanning and CloudWorx™ for MicroStation drafting. The Cyrax /CloudWorx proposal offered >40% cost savings, a shorter proposed schedule, a safer means of data collection, a faster way to get additional information without revisiting the site, and the avoidance of lane closures during field data collection. The project was carried out within budget and on schedule.
- 47% cost savings vs traditional survey/drafting
- Faster project completion
- More complete data; no site revisits needed
- No lane closures
- Overhead sign structure design based directly on point clouds
