Equipment productivity control

Equipment productivity control is the systematic measurement, monitoring and improvement of the output of construction machines (excavators, dozers, loaders, cranes, mixers, trucks), so that the actual output per hour or per day matches, or goes above, the planned (standard) output at the least cost.

$$\text{Productivity} = \frac{\text{Work output (m}^3\text{ or m}^2)}{\text{Equipment hours}}$$

Main points

• Fix the standard output from the manufacturer's data, job conditions and efficiency factors.
• Record machine hours, working, idle and breakdown time (log books, hour-meter reading) and the output achieved.
• Compare the actual output with the standard and find the causes of the difference.
• Take corrective action:
  • Preventive maintenance and prompt repair to avoid breakdown.
  • Select the right size and type of machine, and balance fleets (e.g. trucks and excavator).
  • Skilled operators and training; proper fuel and spares.
  • Good site layout, haul roads and job planning to reduce waiting.
• It reduces cost per unit of work, avoids delay and protects the useful life of equipment.
