CEC Construction Equipment Costs & Ownership 2

Question 1

Which of the following best describes the 'standby rate' for rented construction equipment?

Accepted Answer

A reduced rate charged when equipment is on-site but not operating

Answer

A standby rate is a reduced charge applied when rented equipment is on-site and available but not actively being used, compensating the owner for holding the machine idle.

Question 2

The 'ownership and operating (O&O) cost' method for pricing equipment use is most closely associated with which reference publication?

Accepted Answer

Caterpillar Performance Handbook

Answer

The Caterpillar Performance Handbook is widely recognized as a primary reference for calculating ownership and operating costs of heavy construction equipment.

Question 3

When estimating equipment costs for a project in a remote location, which additional cost factor is most important to include?

Accepted Answer

Mobilization and demobilization costs

Answer

Remote locations require transporting equipment to and from the site, making mobilization and demobilization a significant and often overlooked cost that must be included in the estimate.

Question 4

Which factor most directly affects the hourly fuel cost estimate for a piece of heavy equipment?

Accepted Answer

The engine horsepower and load factor

Answer

Fuel consumption is directly proportional to engine horsepower and the load factor (the percentage of maximum power the engine uses), making these the primary drivers of hourly fuel cost.

Question 5

An estimator is comparing owning versus renting a concrete pump for a project. If the breakeven point is 1,200 hours per year, what should the estimator recommend if annual usage is projected at 800 hours?

Accepted Answer

Rent the pump because usage is below the breakeven point

Answer

When projected usage falls below the breakeven point, renting is more cost-effective than owning because ownership costs are not fully recovered over the limited hours of use.
