1. A general building contractor is reviewing a set of construction
documents before preparing a bid. Which document is most useful for
identifying the intended dimensions, materials, assemblies, and
construction details of the proposed work?
A. Payment application
B. Construction drawings and specifications
C. Daily payroll report
D. Subcontractor invoice
Answer: B
Rationale: Construction drawings and specifications collectively
communicate the designer's requirements concerning dimensions,
,materials, workmanship, assemblies, and other requirements necessary for
estimating and construction.
2. When reviewing construction plans for estimating purposes, what is
the primary reason a contractor should compare architectural
drawings with structural, mechanical, electrical, and plumbing
drawings?
A. To determine which subcontractor has the lowest labor rate
B. To identify conflicts, coordination requirements, and scope that may
affect the estimate
C. To eliminate the need to review specifications
D. To determine the owner's preferred payment method
Answer: B
Rationale: Cross-referencing drawings helps identify coordination issues,
penetrations, equipment locations, dimensions, and scope responsibilities
that can materially affect construction cost and execution.
3. A contractor is estimating concrete for a rectangular slab measuring 60
feet by 40 feet and 6 inches thick. Approximately how many cubic
yards of concrete are required before allowing for waste?
A. 29.6 cubic yards
B. 44.4 cubic yards
,C. 60.0 cubic yards
D. 88.9 cubic yards
Answer: B
Rationale: The volume is 60 × 40 × 0.5 = 1,200 cubic feet. Dividing by 27
cubic feet per cubic yard gives approximately 44.4 cubic yards before
waste or other adjustments.
4. Which estimating practice provides the strongest basis for developing
a reliable construction bid?
A. Estimating only the largest visible materials
B. Using historical costs without reviewing the current project documents C.
Measuring quantities systematically and applying appropriate labor,
material, equipment, subcontractor, overhead, and profit costs
D. Using the owner's preliminary budget as the final contractor price
Answer: C
Rationale: A comprehensive estimate accounts for measurable quantities
and all relevant direct and indirect costs before appropriate overhead and
profit are incorporated.
5. A contractor discovers that the specifications require a higher-grade
material than the material shown on the drawings. What should the
contractor generally do during estimating?
, A. Ignore the specification
B. Price the higher-grade material and seek clarification through the
appropriate process if the documents conflict
C. Automatically substitute the cheaper material
D. Remove the material from the estimate
Answer: B
Rationale: Specifications can establish material and performance
requirements, and discrepancies should be identified and resolved rather
than ignored or unilaterally substituted.
6. Which item is generally considered a direct construction cost?
A. Corporate office rent unrelated to the project
B. Project-specific concrete purchased for the job
C. General advertising expense
D. Corporate accounting software
Answer: B
Rationale: A direct cost can be specifically attributed to a particular
construction project, such as project-specific materials, labor, or
equipment.
7. Which item is most appropriately classified as an indirect project cost?
