It has become practice on many sites to employ a supervisor to control cranes and their use and maintenance. Even with capable supervision, forward notice of casting operations, movement of cages and handling of steel is essential. Lifting beams, chains and slings must be readily available and even duplicated if necessary to prevent time being wasted in backtracking to pick up gear for a particular operation. Radio communication is an important tool in controlling equipment, indeed the radio link between banskman, supervisor and operatives, may be advantageously monitored by the site supervisor or manager, when priorities can be allocated in the event of upset or delay.

Tower cranes have revolutionised construction with their ability to reach and service large areas of the site. Now, at a signal, a man in the workplace can have a massive form or heavy skip moved from one place to another accurately and can have supplies and equipment brought to the work level and inspection or working platforms handled in substantial pieces. Unfortunately a large number of activities on site have 34 been allowed to become crane-dependent, and often the crane becomes the cause of bottlenecks in production.

Reinforcement should be investigated to determine whether continuity of placement can be achieved. Joints, day joints, construction joints and such like should be examined. Dependencies should be identified. The inclusion of admixtures in the concrete should be questioned and their effects anticipated. Excessive amounts of cast in fixings must be avoided and time allocated for installation and checking of same. Previous supervisory experience and trades skill must be established and consideration given to any necessary training.
