Control of materials on sites (quality and quantity) / Dahlim Ismail dan Izhar Ismail

In general, control means influencing events, circumstances, happenings and performance to accord with what was intended and planned. Effective control needs the essential prerequisites of a plan, knowledge of what is actually happening and the ability to use the information and convert it into the right kind of action. Management is a collective term used to refer to all functions and responsibility needed to administrate a construction site, and therefore each responsibility within its own sphere of operations needs to know what is required of it, what is actually happening as near to the time of the event as possible, so that progressive decision can be made and translated into action in order that the collective results will produce the optimum profitability and reward for all concerned.
