PT RAFT is feasible under following conditions

  • If Safe Baring Capacity (SBC) is very low

  • If depth of RCC raft is more

  • If RCC raft construction is Un-economical

  • NON-UNIFORM SBC, HARD ROCK STRATA IN MAJOR PORTION

  • HIGH COST OF EXCAVATION TO MAINTAIN UNIFORM LEVEL

  • HIGH WATER PRESSURE

FACTORS RESPONSIBLE FOR REDUCTION IN COST

  • Reduction of material quantities and cost

  • Reduction of labour and material handling costs

  • Reduced total building height and cladding cost.

  • Simplified and cheaper formwork.

  • Reduction in Indirect costs due to faster construction cycle.

ADVANTAGES OF PT RAFT

  • Reduction In Raft Depth

  • Resistance To Water Pressure

  • Saving In Concrete Cost

  • Saving In Reinforcement Cost

  • Saving In Excavation Cost

  • And Support Cost
