1. What does an Unlimited limitation allow a North Carolina general
contractor to do?
A. Contract only residential projects
B. Contract projects up to $750,000
C. Contract projects up to $1.5 million
D. Contract without restriction as to the value of a single project
Rationale: Under North Carolina's current licensing structure, an
Unlimited license limitation does not impose a dollar-value ceiling on
an individual project. The limitation differs from Limited and
Intermediate classifications, which have specified project-value limits.
2. Which type of construction is included within the Building
Contractor classification?
,A. Only single-family residences
B. Only commercial buildings
C. Commercial, industrial, institutional, and residential building
construction
D. Only state-owned buildings
Rationale: The Building classification is broad and encompasses
commercial, industrial, institutional, and residential building
construction. It is not restricted to one occupancy or building type.
3. Before excavation begins, what is the primary purpose of
establishing the building layout?
A. Determine the final paint colors
B. Transfer the dimensions and locations shown on the plans to the
site
C. Determine the electrical load
D. Calculate the roofing warranty
Rationale: Layout establishes the actual location, dimensions,
elevations, and orientation of the proposed construction. Accurate
layout is essential because errors at this stage can affect foundations
and every subsequent phase.
4. What is the main purpose of a benchmark on a construction site?
,A. Establish property ownership
B. Determine concrete strength
C. Provide a known elevation reference
D. Locate underground electrical cables
Rationale: A benchmark is a fixed reference point with a known
elevation. Contractors and surveyors can use it to establish elevations
for foundations, floors, drainage, and other construction elements.
5. Which soil condition generally provides the greatest concern for
foundation settlement?
A. Well-compacted granular soil
B. Dense gravel
C. Loose or poorly compacted fill
D. Competent rock
Rationale: Loose fill can compress under structural loads, producing
differential or excessive settlement. Proper soil evaluation and
compaction help reduce this risk.
6. What is the primary purpose of site grading around a building?
A. Increase wall thickness
B. Direct surface water away from the structure
, C. Increase concrete strength
D. Reduce roof loading
Rationale: Proper grading helps prevent water from collecting against
foundations and slabs. Finished grades should generally promote
drainage away from the building.
7. What is the principal purpose of erosion and sedimentation
controls during construction?
A. Increase building height
B. Reduce concrete curing time
C. Prevent disturbed soil and sediment from leaving the construction
site and entering protected areas
D. Improve interior ventilation
Rationale: Construction activities disturb soil and can cause sediment
to migrate through stormwater runoff. Erosion and sedimentation
controls help protect adjoining property, drainage systems, and water
resources.
8. What is the primary function of a footing?
A. Support roof sheathing
B. Distribute structural loads to the supporting soil
