Procedures for designing Raft foundation in building?

Designing a raft foundation involves several key steps: first, assess soil conditions through geotechnical investigations to determine bearing capacity and settlement characteristics. Next, calculate the loads from the building, including dead, live, and environmental loads, to ensure the raft can distribute these loads evenly across the foundation. The raft's thickness and reinforcement must be designed based on structural analysis, considering factors like bending moments and shear forces. Finally, construct detailed drawings and specifications to guide the construction process, ensuring compliance with relevant codes and standards.
