1) Construction equipment productivity refers to the time equipment is productively working, and higher productivity means tasks can be completed more efficiently. Poor productivity increases unexpected costs and budget overruns. 2) The document provides productivity rates for various pieces of heavy construction equipment processing different materials, such as a 32-ton bulldozer moving 83 cubic meters of earth per hour. 3) It also lists factors that affect productivity like rework, lack of experience, and regulatory delays, and provides tips to maximize productivity like regular maintenance, trained operators, and following safety guidelines.

2. Construction Equipment Productivity
• Equipment productivity generally refers to the time during which
the machine is in operation performing productive work. The more
efficiently the workers can complete their tasks, the higher the
production level is.
• Poor equipment productivity is a leading contributor to many
problems that contractors face, including increased and
unexpected costs that cause budget creeps.

3. Bulldozers
• 32 Ton Class- 83 Cum/Hr
• Earth Volume less than 30000 Cum- 20 ton class wet type

16. Tips to ensure maximum productivity at the site
• Read and follow the manufacturer’s instructions and maintenance
tips. It can help you to operate the machine efficiently.
• Ensure that the employee who is operating the construction
equipment is skilled and trained in doing so, as inexperienced
employees can damage the machinery or even injure themselves
or others, causing delays and increasing cost.
• Before starting the day, check the machine thoroughly.
• Check the machine at the end of the day too to find out any
possible damage.
• Clean the parts that made the most contact with the soil and
debris.
• Keep the engine completely shut off while re-fuelling the
equipment.

17. • Follow a periodic maintenance schedule
• Keep the equipment properly greased and lubricated.
• Lubricate the equipment wisely with the recommended grade of
grease.
• Make sure that you replace original parts in your construction
equipment as otherwise there could be major defaults in the long
run.
• Make sure that each tyre has the right pressure
• Ensure you follow all the safety guidelines and the workers are also
aware of the safety norms so as to minimize accidents.
