The equipment management information service is necessary for keeping track of the equipment running, the fuel consumption, major overhauls and replacement of parts on individual equipment.
Experience of those in the industry reveals that a manual system is satisfactory for an inventory of fewer than 500 equipment. Beyond that number, a computerized system is more time saving and economical. It takes a minimum of three persons to operate a computerised data processing system, and the same number of persons are required to handle 500 equipment in a manual system. The retrieval of information and the facility for manipulation of raw data by the computer have caused management to rely less on intuition and more on informed analysis as a method of making equipment decisions. It is probable that computer programs for equipment costing and analysis will be made available to small contractors, so that fleets of lesser than 500 equipment can he managed economically through computer methods rather than manually. The final test on this will be the cost of labour required to collate the raw data for analysis.
The equipment information must be pertinent to the day-to-day decisions and must be reliable enough to instill confidence in their use. The information system must be simple and flexible enough to survive in the construction project environment.
The diversity falsification at which the contractors construct complicate the record keeping job. Transferring records between job sites as the equipment is transferred is often awkward. Documents that should be transferred with each equipment include its maintenance folder, preventive maintenance records, maintenance instructions, lubrication charts, parts catalog, tyre records, and any operating instructions. Certain parts that are carried in inventory should be transferred with the equipment, and inventory records should be adjusted accordingly.
