1. What is the primary purpose of a site investigation before
beginning a major engineering construction project?
A. To determine the contractor's profit margin
B. To eliminate the need for engineering plans
C. To identify existing site conditions that may affect construction
D. To establish the final payment schedule
Answer: C. To identify existing site conditions that may affect
construction
Rationale: A site investigation provides information about soil,
groundwater, existing utilities, topography, access, environmental
conditions, and other physical characteristics. Understanding these
conditions allows the contractor and design team to plan appropriate
construction methods and reduce unforeseen problems.
, 2. Which instrument is commonly used by surveyors to measure
horizontal and vertical angles accurately?
A. Plate compactor
B. Total station
C. Concrete vibrator
D. Moisture meter
Answer: B. Total station
Rationale: A total station is an electronic surveying instrument that
combines angle measurement with electronic distance measurement.
It is widely used to establish points, elevations, alignments, and
locations during engineering construction.
3. What is the primary function of a benchmark in construction
surveying?
A. To store construction materials
B. To provide a known elevation reference
C. To measure concrete strength
D. To determine equipment fuel consumption
Answer: B. To provide a known elevation reference
Rationale: A benchmark is a fixed reference point with a known
elevation. Surveyors use it to establish or transfer elevations
,throughout a project so that grades, foundations, drainage systems,
roads, and other features are constructed at the required elevations.
4. When preparing a construction schedule, the critical path
identifies activities that:
A. Have the lowest labor cost
B. Can always be delayed without consequences
C. Determine the minimum project completion time
D. Require the largest number of workers
Answer: C. Determine the minimum project completion time
Rationale: The critical path consists of activities that control the
earliest possible completion date of the project. Delaying a critical-
path activity generally delays the project unless corrective action or
schedule recovery measures are implemented.
5. What is the primary purpose of a construction submittal?
A. To replace the contract
B. To provide required technical information for review and approval
C. To establish the contractor's tax rate
D. To eliminate inspections
Answer: B. To provide required technical information for review and
approval
, Rationale: Submittals may include shop drawings, product data,
samples, mix designs, certifications, and other technical information.
They allow the appropriate project parties to verify that proposed
materials and methods comply with project requirements.
6. Which soil property describes the ability of soil to support loads
without excessive deformation or failure?
A. Bearing capacity
B. Permeability
C. Plasticity
D. Moisture content
Answer: A. Bearing capacity
Rationale: Bearing capacity refers to the ability of soil to safely
support applied loads. It is particularly important for foundations,
retaining structures, embankments, and other structures that transfer
loads into the ground.
7. What is the main purpose of soil compaction?
A. To increase voids in the soil
B. To reduce soil density
C. To increase soil density and improve stability
D. To increase the soil's organic content
