INTRODUCTION
This comprehensive assessment evaluates mastery of cost estimation principles
and engineering estimating practices as taught in ENGV 380 Quiz 2 at Liberty
University. The examination assesses foundational cost terminology, estimate
classification systems, quantity takeoff procedures, labor and material pricing
methodologies, equipment cost analysis, cost indices, bidding strategies,
contingency management, and the ethical standards governing professional
estimators. The multiple-choice format includes scenario-based problems
requiring critical thinking, numerical calculation, and application of industry-
standard estimating practices. Each question demands synthesis of conceptual
understanding with practical estimating scenarios, preparing candidates for
professional roles in construction cost management and project controls within
the civil engineering and construction industries.
,SECTION ONE: QUESTIONS 1–150
Question 1
A construction estimator is preparing a conceptual estimate for a new office
building. At this early stage, the project scope is defined only by the building type
and gross square footage. Which of the following estimating methods is most
appropriate for this level of project definition?
A. Detailed unit price estimate
B. Assembly system estimate
C. Parameter cost estimate
D. Bid estimate
Correct answer: C
RATIONALE: Parameter cost estimates are used when project scope is defined
only by general parameters such as building type, gross square footage, or
number of units. These estimates use historical cost data expressed as cost per
square foot or cost per unit. Detailed unit price estimates require complete plans
and specifications. Assembly system estimates use combined work items but
require more design definition. Bid estimates are prepared from complete
contract documents and reflect the contractor's final pricing.
Question 2
An estimator is reviewing historical cost data for a hospital project completed
three years ago. The project cost $285 per square foot at that time. Using a
building cost index that has increased 12% over the three-year period, what is the
adjusted cost per square foot for a similar hospital to be built today?
A. $285.00
B. $319.20
,C. $253.57
D. $342.00
Correct answer: B
RATIONALE: The adjusted cost is calculated by multiplying the historical cost
by the index ratio. With a 12% increase, the adjustment factor is 1.12. $285.00 ×
1.12 = $319.20 per square foot. Option A represents no adjustment. Option C
incorrectly subtracts the percentage. Option D applies an incorrect calculation.
Cost indices are essential tools for adjusting historical cost data to current dollars.
Question 3
Which of the following best defines the term "quantity takeoff" in construction
estimating?
A. The process of negotiating material prices with suppliers
B. The measurement and listing of all materials and work items required for a
project
C. The calculation of labor productivity rates
D. The analysis of equipment ownership costs
Correct answer: B
RATIONALE: Quantity takeoff is the detailed process of measuring and listing
all materials, labor, and equipment required to complete a construction project. It
involves systematically reviewing project drawings and specifications to
determine quantities of each work item. Quantity takeoff is the foundation of
accurate detailed estimates. Negotiating prices, calculating labor productivity, and
analyzing equipment costs are separate estimating functions that occur after
quantities are determined.
Question 4
, An estimator is calculating the cost of concrete for a foundation. The foundation
requires 150 cubic yards of concrete. The concrete supplier quotes $145 per cubic
yard, including delivery. What is the total material cost for the concrete?
A. $19,750
B. $21,750
C. $22,500
D. $20,250
Correct answer: B
RATIONALE: Total material cost equals quantity multiplied by unit price. 150
cubic yards × $145 per cubic yard = $21,750. Option A ($19,750) results from
using $131.67 per cubic yard. Option C ($22,500) results from using $150 per
cubic yard. Option D ($20,250) results from using $135 per cubic yard. Accurate
multiplication of quantity by unit price is fundamental to material cost estimation.
Question 5
Which of the following is considered a direct cost in construction estimating?
A. Project management salaries for home office staff
B. Building permit fees
C. Labor wages for workers installing formwork
D. General liability insurance
Correct answer: C
RATIONALE: Direct costs are expenses directly attributable to a specific
construction activity or work item. Labor wages for workers installing formwork
are a direct cost because they can be traced to a specific work item. Home office
project management salaries, building permit fees, and general liability insurance
are indirect costs or project overhead that cannot be directly attributed to a
specific work item. Understanding the distinction between direct and indirect
costs is essential for accurate estimating and cost control.
