The projection of Raft beyond the Outer face of the Structure depends on different design aspects -

- Buoyancy.
- The additional wall around the structure for better waterproofing.
- Reinforcement Anchorage of main structure in the Raft.
- Providing Haunch at the junction of Structure and Raft which will enhance joint durability.
