Detailed design considers an in-depth study of the project area, design of all major and supporting structures. It includes topography mapping, surface and subsurface geological investigation, detailed engineering design of project components and preparation of constructional level drawings such as civil and reinforcement drawings. Furthermore, electromechanical and transmission line design are worked out and drawings are prepared. Similarly, construction planning, detailed quantity estimate and financial analysis of project are performed. Depending upon the client requirement, tender document of civil, hydro-mechanical, electro-mechanical and transmission line are prepared.
