1. What is the primary purpose of a construction site survey before
major earthwork begins?
a. To determine the contractor's profit margin
b. To establish existing grades, elevations, and site conditions
c. To select the project's insurance provider
d. To determine the final paint colors
Answer: b. To establish existing grades, elevations, and site conditions
Rationale: A preconstruction survey establishes the existing
topography and important control points. This information is essential
for determining excavation and embankment quantities, drainage
patterns, finished elevations, and the relationship between proposed
improvements and existing conditions.
, 2. Which instrument is commonly used to determine differences in
elevation between points on a construction site?
a. Transit only
b. Level
c. Soil penetrometer
d. Concrete vibrator
Answer: b. Level
Rationale: A level is designed to establish a horizontal line of sight so
that differences in elevation can be determined from staff readings.
Accurate elevation control is fundamental to grading, drainage,
roadway construction, and utility installation.
3. A benchmark on a construction project is best described as:
a. A temporary storage area
b. A permanent or established reference point with a known elevation
c. A location where concrete is mixed
d. A point where equipment is fueled
Answer: b. A permanent or established reference point with a known
elevation
,Rationale: A benchmark provides a known elevation from which other
elevations can be established. Construction crews use benchmarks to
maintain consistent vertical control throughout a project.
4. What is the primary purpose of a cut-and-fill calculation?
a. To determine paint quantities
b. To compare excavation quantities with embankment requirements
c. To calculate concrete curing time
d. To determine equipment insurance premiums
Answer: b. To compare excavation quantities with embankment
requirements
Rationale: Cut-and-fill calculations determine how much material
must be excavated and how much is needed for embankment. They
help contractors plan hauling, equipment requirements, material
disposal, and potential balancing of earthwork.
5. If a proposed roadway grade is higher than the existing ground,
the work will generally require:
a. Excavation only
b. Embankment or fill
c. Pavement removal only
d. Concrete demolition
, Answer: b. Embankment or fill
Rationale: When the proposed elevation is above the existing ground,
additional material must normally be placed and compacted to
achieve the design grade. This material forms an embankment or fill.
6. What is the purpose of a grade stake?
a. To indicate the required elevation or grade for construction
b. To measure concrete temperature
c. To test asphalt viscosity
d. To identify equipment ownership
Answer: a. To indicate the required elevation or grade for
construction
Rationale: Grade stakes communicate important vertical information
to construction crews. They can identify cut or fill requirements and
help operators establish the required finished grade.
7. Which soil property is most directly related to the ability of soil to
support loads?
a. Bearing capacity
b. Color
c. Odor
d. Surface temperature
