4. Pipeline & Utility Systems:
   • Perform stress analysis of critical pipelines using CAESAR II and prepare load schedules for pipe support systems.
   • Conduct hydraulic analysis for cross-country and in-plant pipelines.
   • Design cross-country pipelines and steel pipes in compliance with international standards like AWWA M11, ASME codes, and other relevant guidelines.
5. Advanced Analyses:
   • Conduct surge analysis using Bentley’s WaterHammer.
   • Design distribution networks using WaterGEMS.
6. 3D Modeling & Drawing Reviews:
   • Guide teams in preparing L-section drawings in CIVIL 3D and generating 3D models of process buildings.
   • Review and evaluate drawings and 3D models for accuracy and adherence to design specifications.
7. Client & Consultant Coordination:
   • Interact with clients and consultants to obtain design deliverables approval.
   • Collaborate with interdisciplinary teams to ensure seamless project execution.
8. Specialized Systems:
   • Mechanical design of pumping stations such as raw water intake systems, clear water pump houses, and treated water pumping stations for STP as per CPHEEO guidelines and Hydraulic Institute standards.
   • Detailed engineering of piping and utility systems in water and wastewater treatment plants as per ASME B31.3 and relevant Indian standards.
