Featuring bridge, tunnel, and ecological works impacted by surrounding traffic and adjacent construction, the 24.6-kilometer urban road renovation and expansion project in Zigong presented coordination and communication challenges, compounded by sensitive timelines. Zigong Academy of Urban Planning and Design realized that traditional design and construction management methods would not suffice. They needed to implement lifecycle BIM strategies in a connected data environment.

They selected ContextCapture to establish a reality model of the entire line, while Bentley’s open BIM applications modeled the roadway structures, saving approximately USD 30 million in earthworks costs and improving change management by 10%. Using ProjectWise as the collaborative management platform, the team resolved over 400 errors, reducing economic losses by millions of yuan and the project schedule by 55 days. The BIM and reality models will be used for intelligent construction, operation, and maintenance to achieve digital lifecycle management.
