1. What is the primary purpose of a construction site plan?
A. To determine employee wages
B. To show project layout, structures, utilities, and site features
C. To calculate taxes
D. To order office supplies
Correct Answer: B. To show project layout, structures, utilities,
and site features
Rationale: A site plan provides a graphical representation of
the proposed work and important site conditions.
2. Which document normally contains detailed dimensions
and construction requirements?
A. Payroll register
B. Building drawings and specifications
C. Delivery receipt
D. Equipment log
Correct Answer: B. Building drawings and specifications
Rationale: Drawings and specifications communicate the
dimensions, materials, workmanship, and requirements of the
project.
3. What is the main purpose of excavation shoring?
A. Increase excavation depth automatically
B. Prevent soil from collapsing into the excavation
,C. Improve concrete color
D. Reduce equipment fuel use
Correct Answer: B. Prevent soil from collapsing into the
excavation
Rationale: Shoring supports excavation walls and helps protect
workers from cave-ins.
4. Which soil generally has the greatest cohesion?
A. Gravel
B. Sand
C. Clay
D. Crushed stone
Correct Answer: C. Clay
Rationale: Clay particles have cohesive properties that allow
the soil to stick together more readily than granular soils.
5. What is a major hazard associated with an unsupported
trench?
A. Excessive lighting
B. Cave-in
C. Concrete staining
D. Equipment overheating
Correct Answer: B. Cave-in
Rationale: Trench wall collapse is one of the most serious
hazards in excavation work.
6. What does compaction accomplish in earthwork?
A. Increases soil voids
,B. Removes all moisture
C. Increases soil density and stability
D. Makes soil permanently waterproof
Correct Answer: C. Increases soil density and stability
Rationale: Proper compaction reduces air voids and improves
the load-bearing characteristics of soil.
7. Which machine is commonly used to move large quantities
of earth over relatively short distances?
A. Bulldozer
B. Drill press
C. Tower crane only
D. Pipe wrench
Correct Answer: A. Bulldozer
Rationale: Bulldozers are designed for pushing, spreading, and

precise grades and slopes.
9. What is the primary function of an excavator?
A. Digging and material handling
, B. Painting buildings
C. Testing electrical circuits
D. Compacting asphalt exclusively
Correct Answer: A. Digging and material handling
Rationale: Excavators use a boom, arm, and bucket for
excavation and various material-handling tasks.
10. What does a loader primarily do?
A. Load and move loose materials
B. Install electrical wiring
C. Survey property boundaries
D. Cure concrete
Correct Answer: A. Load and move loose materials
Rationale: Wheel and track loaders are commonly used to
scoop, transport, and load aggregate, soil, and other materials.
11. What is the purpose of a benchmark in surveying?
A. To provide a known elevation reference
B. To determine equipment horsepower
C. To identify concrete strength
D. To calculate fuel consumption
Correct Answer: A. To provide a known elevation reference
Rationale: A benchmark is a fixed reference point with a known
elevation.
12. Which instrument is commonly used to establish
horizontal and vertical angles in surveying?
A. Total station
