Coronation Pillar is a new wastewater treatment plant in New Delhi, treating 318 million liters a day of sewage while reducing annual carbon emissions by approximately 14,450 tons. L&T Construction delivered the large-scale project that required multiple structures to be designed and constructed within a confined site amid liquefaction and seismic risks. Realizing that manual design and analysis methods would be ineffective to ensure optimal structural results, L&T needed dynamic 3D modeling and structural analysis technology.They selected STAAD to model multiple designs with various loading configurations and applications, achieving a land savings of 17.8% and reinforced cement concrete material savings of 5%, reducing both the project’s physical and carbon footprints. Using Bentley’s application, L&T Construction quickly analyzed different structural designs, reducing the time to arrive at an optimal solution by 75%, compared to manual design approaches. The digital structural approach applied during this project serves as a benchmark, resulting in significant added value across other L&T Construction projects.
