Background:
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.
Benefits:
- 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
