Case Study: Citic Heavy Industries achieves a green, smart cement factory and $2M in equipment maintenance savings with Bentley's collaborative BIM and iTwin Services

Citic Heavy Industries Uses Collaborative BIM Technology to Deliver Green, Smart Cement Factory

Citic Heavy Industries was contracted to design, procure, construct, and deliver a USD 135.96 million, 4,500-ton-per-day green, smart cement factory in Fujian, China and faced complex multidisciplinary coordination, equipment design, and operations-integration challenges. To move beyond conventional methods and enable intelligent plant management, Citic required a cloud-based collaborative BIM platform and integrated applications — engaging Bentley and its tools (OpenBuildings, OpenPlant, ProjectWise, and iTwin® Services) to support 3D parametric equipment design and a connected data environment.

Bentley implemented a collaborative 3D BIM and digital twin solution—using OpenBuildings and OpenPlant for modeling, ProjectWise for collaboration, and iTwin Services for digital twin and online equipment monitoring—enabling design-construction synchronization and predictive maintenance. The Bentley-powered approach cut design changes by 80%, shaved one month off design time, eliminated construction collisions, saved three months and USD 3 million in project costs, reduced equipment maintenance costs by USD 2 million, lowered O&M costs by over 30%, and is expected to save Fujian Ansha about USD 1.24 million annually while reducing electricity use by 3.5 million kWh.
