13.2 Placing.
The concrete shall be deposited as nearly as practicable in its final position to avoid re-handling. The concrete shall be placed and compacted before initial setting of concrete commences and should not be subsequently disturbed.
Methods of placing should be such as to preclude segregation. Care should be taken to avoid displacement of reinforcement or movement of form work. As a general guidance, the maximum permissible free fall of concrete may be taken as 1.5 m.
