A Digital City Initiative Capital city and political, economic, and cultural center of Yunnan province, Kunming City is developing rapidly and accelerating pace to transform itself into a regional hub as part of an RMB 90 billion urban revitalization effort to create a digital city. Multiple provincial and key municipal public private partnership (PPP) projects are being initiated to stimulate and support the urban development, including an RMB 9.9 billion rapid transport system to improve transportation infrastructure in the city’s southeastern section. The new roadway network spans 20 square kilometers and has a total construction distance of 65.48 kilometers, consisting of roads, bridges, tunnels, and underground pipe corridors. Yunnan Yunling Engineering Cost Consultation (YYECC) was retained as the lead building information modeling (BIM) strategy consultant to effectively manage the project within the schedule and budget. As a PPP project, numerous government ministries, stakeholders, and engineering disciplines required coordination to ensure that investment, financing, design, construction, and maintenance processes met owner requirements. The digital city initiative presentedmassive amounts of fragmented data amongmore than 25 project contracts with over- lapping functions and a 20-year project lifecycle. Faced with these challenges YYECC required an integrated digital solution to effectively manage the complex contract system and develop industrialized, automated processes for data transfer and information sharing. Digitalization Transforms Traditional Management Model As a total solution provider offering BIM lifecycle services, YYECC sought to determine the feasibility of integrating collaborative BIM technology to manage the Kunming PPP rapid transport infrastructure project. The team used Bent- ley’s project management and modeling applications to create an open, connected data environment (CDE), visualize project management, and improve management efficiencies. Leveraging the collaboration and management capa- bilities of ProjectWise with the engineering, design, and visualization capabilities of other Bentley applications, YYECC established a unified management platform and developed a comprehensive, owner-supported BIM methodology. The process was designed to improve collaboration, ensuring real-time information sharing and accessibility, and to optimize lifecycle management of the multidiscipline, long- term PPP initiative. Model and data files, standard process and supervisory documentation, and design and construction information are stored within a single platform for efficient collaboration. Based on the structured format of more than three terabytes worth of stored, accessible data and documents in Projec- tWise, tasks were appropriately divided, assigned, and evaluated, strengthening the organization andmanagement of the project participants. Integrating Bentley’s 3D BIM and visualization applications within the CDE facilitated coordi- nated modeling and more continuous digital workflows from conception through construction and commissioning. The technology and models were used to simulate analysis of the conceptual scheme, fully demonstrating the design intent and economic visibility of the project to shorten decision time. The digital simulation features of Bentley’s applications allowed for real-time analysis of construction progress to keep the project on schedule and to optimize construction management, ensuring accurate material quantities and pricing and improving construction quality. Using LumenRT to share the simulations with executors and directors enhanced appearance of the comprehensive transportation network model so they could better understand the progress and construction tomake more informed decisions and accelerate approval time. The Bentley-based digital solution achieved data integration, collaborative modeling, application analysis, and coordinated information sharing, transforming traditionally fragmented manage- ment into efficient, streamlined processes. Collaborative Design Facilitates Model Integrity Having accurate digital models within the CDE provides the basis for data sharing and enables remote simulation of construction progress and inspection to avoid safety concerns, costly mistakes, and missed project milestones.
