1. What is the main purpose of establishing horizontal control
on a site?
A. To estimate soil type
B. To provide accurate reference points for positioning
C. To design drainage systems
D. To manage construction budgets
Correct Answer: B
Rationale: Horizontal control establishes a network of known
coordinates used to accurately position all construction elements.
2. Which of the following is a common source of error in
construction surveying?
A. Proper instrument calibration
B. Human reading and recording mistakes
C. Use of control points
D. Redundant measurements
, Correct Answer: B
Rationale: Human error, such as misreading instruments or
recording incorrect values, is a common source of surveying
inaccuracies.
3. Which of the following is most important when
interpreting construction plans?
A. Color of drawings
B. Scale and symbols
C. Paper thickness
D. Printing method
Correct Answer: B
Rationale: Understanding scale and symbols is essential for
correctly translating design drawings into field layouts.
4. What is the primary purpose of a traverse in surveying?
A. To estimate construction costs
B. To establish a series of connected survey lines for control
C. To measure wind direction
D. To determine soil chemistry
Correct Answer: B
Rationale: A traverse provides a framework of connected
measurements used to establish control points across a site.
5. Which tool helps ensure vertical alignment during
construction layout?
A. Plumb bob
B. Hygrometer
, C. Thermometer
D. Barometer
Correct Answer: A
Rationale: A plumb bob is used to verify vertical alignment and
ensure structures are properly oriented.
6. What does “offset” mean in construction surveying?
A. A financial adjustment
B. A perpendicular distance from a reference line
C. A type of legal document
D. A soil compaction measurement
Correct Answer: B
Rationale: An offset is a measured perpendicular distance used to
locate points relative to a baseline or alignment .
7. Which of the following best describes electronic data
collectors in surveying?
A. Devices used for legal documentation
B. Tools that store and process field measurement data digitally
C. Equipment for soil testing
D. Machines used for concrete mixing
Correct Answer: B
Rationale: Electronic data collectors record and store survey
measurements, improving accuracy and efficiency in fieldwork .
8. What is the main benefit of redundancy in survey
measurements?
A. Increases project cost
, B. Improves accuracy and allows error detection
C. Eliminates need for instruments
D. Reduces fieldwork time
Correct Answer: B
Rationale: Redundant measurements help identify and correct
errors, improving overall accuracy of survey results .
9. Which surveying method is used to determine elevation
differences over long distances?
A. Trigonometric leveling
B. Soil sampling
C. Photogrammetry only
D. Chain surveying only
Correct Answer: A
Rationale: Trigonometric leveling uses angles and distances to
calculate elevation changes over extended areas .
10. What is the primary function of survey benchmarks in
construction projects?
A. To determine material costs
B. To provide known elevation references
C. To mark property ownership
D. To define zoning boundaries
Correct Answer: B
Rationale: A benchmark is a permanently established point with a
known elevation. It serves as the primary vertical control reference
for setting grades and elevations .
