1. A construction surveyor establishing horizontal control for a
commercial site development project in California is primarily
concerned with which of the following objectives when setting
permanent control monuments prior to grading operations?
A. Determining underground utility voltage capacity
B. Establishing accurate reference points for future layout and
measurements
C. Calculating concrete curing temperatures
D. Measuring asphalt density during paving operations
,B. Establishing accurate reference points for future layout and
measurements
Permanent horizontal control monuments provide stable and repeatable
reference positions used throughout construction activities. Accurate
control is essential for property boundaries, building layout, grading, and
utility installation.
2. During the interpretation of a topographic map for site layout
purposes, contour lines that are spaced closely together indicate
which of the following site conditions?
A. A gentle slope with minimal elevation change
B. A flat plateau with no measurable grade
C. A steep slope with rapid elevation change
D. A drainage basin with standing water
C. A steep slope with rapid elevation change
Closely spaced contour lines represent rapid elevation changes over short
horizontal distances, indicating a steep slope. Widely spaced contours
indicate flatter terrain.
3. A survey crew uses a benchmark with a known elevation of 248.60
feet. After taking a backsight reading of 5.20 feet, what is the height of
instrument (HI)?
,A. 243.40 feet
B. 248.60 feet
C. 253.80 feet
D. 254.20 feet
C. 253.80 feet
The height of instrument is calculated by adding the backsight reading to
the benchmark elevation. Therefore, 248.60 + 5.20 = 253.80 feet.
4. Which surveying instrument is specifically designed to simultaneously
measure horizontal angles, vertical angles, and distances electronically
during construction layout operations?
A. Builder’s level
B. Transit
C. Total station
D. Hand level
C. Total station
A total station integrates electronic distance measurement with angular
measurement capabilities, allowing highly accurate site layout, coordinate
determination, and construction staking.
, 5. In California site development projects, what is the primary purpose of
establishing a property line setback before beginning structural
layout?
A. To increase concrete strength
B. To maintain compliance with zoning and building regulations
C. To improve soil compaction
D. To determine roof drainage flow
B. To maintain compliance with zoning and building regulations
Setbacks are legally required minimum distances between structures and
property boundaries. They ensure compliance with local zoning ordinances,
fire safety requirements, and land use regulations.
6. A leveling rod reading taken on a foresight point is 4.75 feet, and the
height of instrument is 112.30 feet. What is the elevation of the
foresight point?
A. 107.55 feet
B. 116.05 feet
C. 117.05 feet
D. 108.75 feet
A. 107.55 feet
