Question 1

A cost consultant identifies a systematic overestimation of labor productivity in multiple project estimates. This type of recurring error is BEST characterized as:

Accepted Answer

Systematic bias

Answer

Recurring errors in the same direction across multiple estimates indicate systematic bias, which must be corrected through process improvement or calibration.

Question 2

Which AACE Recommended Practice provides guidance on the required content and format for a basis of estimate document?

Accepted Answer

RP 34R-05

Answer

AACE RP 34R-05 specifically addresses the required content and structure for a basis of estimate document in cost engineering.

Question 3

An owner requires that all cost estimates submitted by contractors be independently validated. This requirement is an example of which quality management function?

Accepted Answer

Quality assurance

Answer

Requiring independent validation of estimates is a quality assurance function, as it ensures systematic processes are in place to maintain estimate reliability.

Question 4

Which statistical tool is MOST useful for identifying whether cost estimate variations are within acceptable control limits over time?

Accepted Answer

Control chart

Answer

Control charts track process performance over time and display upper and lower control limits to identify whether variations are within acceptable ranges.

Question 5

A contractor submits a change order supported by cost data from a similar but much larger project. What quality concern does this raise?

Accepted Answer

The unit costs may not be scalable and may not reflect the actual scope

Answer

Cost data from projects of significantly different scale may not translate accurately due to economies or diseconomies of scale, making the comparison unreliable.
