2026–2027 TESTING CYCLE
SECTION 1: SURVEY PLANNING (Questions 1–10)
Question 1: A control survey is primarily used to:
Answer: Establish a framework of reference points for horizontal and vertical control for
subsequent surveys.
Rationale: Control surveys establish a network of reference points (horizontal and vertical) that
serve as the basis for all subsequent survey work, including topographic, route, and construction
surveys. The accuracy of the control survey determines the overall accuracy of the project.
Question 2: A topographic survey is performed to:
Answer: Determine and map the configuration of the ground surface and location of natural and
man-made features.
,Rationale: Topographic surveys measure and map the earth's surface features, including
contours, elevations, natural features (rivers, trees), and man-made features (buildings, roads,
utilities). These surveys are essential for engineering design and project planning.
Question 3: The primary difference between a topographic survey and a planimetric survey is:
Answer: A topographic survey shows elevations and contours; a planimetric survey shows only
horizontal positions of features.
Rationale: Planimetric surveys map the horizontal positions of features without elevation data.
Topographic surveys include both horizontal positions and elevations, typically represented by
contour lines. Both are essential for engineering design, but topographic surveys provide the
third dimension needed for grading and earthwork calculations.
Question 4: A benchmark is best defined as:
Answer: A permanent, marked point of known elevation used as a reference for vertical control.
Rationale: A benchmark is a permanent mark established by a surveying agency (e.g., USGS,
NGS) with a precisely determined elevation. It serves as a vertical control point for all leveling
operations. Benchmarks are essential for establishing consistent elevations across a project site.
Question 5: The term "datum" in surveying refers to:
,Answer: A reference surface (horizontal or vertical) used as a basis for computing coordinates or
elevations.
Rationale: A datum is a reference surface from which positions or elevations are measured.
Horizontal datums (e.g., NAD83) provide a reference for coordinates, while vertical datums
(e.g., NAVD88) provide a reference for elevations. Understanding datums is essential for
interpreting survey data.
Question 6: A route survey is typically conducted for:
Answer: The design and construction of linear projects such as highways, railroads, canals, and
pipelines.
Rationale: Route surveys follow a defined corridor for linear infrastructure projects. They
include horizontal and vertical alignment, cross-sections, right-of-way determination, and
construction staking. This is a fundamental surveying activity for civil engineers.
Question 7: The term "accuracy" in surveying refers to:
Answer: The degree of conformity of a measurement to its true value.
Rationale: Accuracy is the closeness of a measured value to the true or accepted value.
Precision is the repeatability of measurements (closeness of measurements to each other). A
measurement can be precise but inaccurate if systematic errors are present.
, Question 8: A construction survey is primarily concerned with:
Answer: Laying out the design on the ground for construction activities.
Rationale: Construction surveys (staking) translate engineering designs from plans to physical
locations on the ground. This includes setting horizontal and vertical control, staking
alignments, and marking locations for excavation, foundations, utilities, and other construction
activities.
Question 9: Geographic Information Systems (GIS) in civil engineering surveying are used for:
Answer: Storing, analyzing, and displaying spatial data for planning and design purposes.
Rationale: GIS integrates spatial data (maps, survey data, aerial imagery) with attribute data to
support planning, design, and decision-making. Civil engineers use GIS for site analysis, utility
mapping, environmental assessment, and infrastructure management.
Question 10: A civil engineer's role in surveying is limited to:
Answer: Engineering surveying activities related to design, construction, and maintenance of
engineered projects.
Rationale: Civil engineers practice engineering surveying, which is distinct from land surveying.
Engineering surveying involves surveying principles for the location, design, construction, and
