About our customer
Shanghai Investigation, Design & Research Institute Co., Ltd.
Balancing efficiency and ecology in China’s karst region
Shanghai Investigation, Design & Research Institute (SIDRI), a provider of world-class turnkey solutions for water and clean energy developments, led an CNY 8.4 billion pumped-storage power station project, focusing on safe, efficient construction and ecological protection. To navigate the region’s challenging terrain, SIDRI needed accurate survey information, integrated data management, and design innovation. Applying Bentley digital solutions, the Caiziba Pumped-Storage Power Station became the first of its kind in an area marked by complex karst geology, including caves, fissures, and underground rivers.
Key Takeaways
CNY 4.5 million in rework savings
42 days cut from construction schedule
CNY 1.2 million in survey cost savings
65% reduction in design errors
The Caiziba Pumped-Storage Power Plant presented significant engineering challenges related to complex karst geology. By leveraging iTwin Capture to unify multi-source data into a single digital twin, SIDRI enhanced efficiency and compliance through real-time collaboration, accelerated decision-making, and seamless integration. Using Bentley’s suite of solutions, the project established a model for future developments in complex terrains, reducing costs and carbon emissions and minimizing ecological impact.
