• Excavation for foundation should be done according to the designs and exact width and depth of the wall should be dug. If extra depth is made due to any reasons or any soft places found, those should be filled in with coarse sand or concrete.
• In case of excavation made through J.C.B. machine, the last layer should be done manually to avoid softening up to the base of foundation.
• In case the water comes in trenches, it should be pumped out immediately.
