CPE Construction Equipment Costs & Management 2

Question 1

The Caterpillar Performance Handbook is primarily used in construction estimating to:

Accepted Answer

Obtain equipment production rates and performance data for cycle time calculations

Answer

The Caterpillar Performance Handbook provides detailed production rates, machine specifications, and performance data used to calculate equipment cycle times and output in estimates.

Question 2

In earthwork estimating, 'bank measure' (BCM or BCY) refers to material:

Accepted Answer

In its natural, undisturbed, in-place condition

Answer

Bank measure describes material in its natural undisturbed state before excavation; this is the baseline measurement from which swell and shrinkage factors are applied.

Question 3

The 'swell factor' in earthwork and equipment estimating accounts for:

Accepted Answer

Volume increase when soil is excavated from its natural undisturbed state

Answer

Swell factor reflects the volume increase—typically 10–40% depending on soil type—that occurs when soil is broken up and loosened during excavation.

Question 4

Job efficiency factor is applied to ideal equipment production rates in estimating to account for:

Accepted Answer

The difference between ideal operating conditions and actual field conditions

Answer

Job efficiency factors (typically expressed as a percentage of ideal output) adjust theoretical production rates to reflect real-world conditions such as operator skill, grade, surface conditions, and management effectiveness.

Question 5

A crawler-mounted excavator is generally preferred over a wheel-mounted excavator when:

Accepted Answer

Working in soft, muddy, or unstable ground conditions

Answer

Crawler excavators distribute weight over a larger track surface area, providing superior stability and flotation in soft or unstable ground where wheeled machines would sink or lose traction.
