**Question 1.** Which Georgia amendment to the International Residential Code (IRC) requires
a minimum ceiling height of 7 ft 6 in in habitable spaces?
A) Amendment 101
B) Amendment 203
C) Amendment 305
D) Amendment 410
Answer: B
Explanation: Georgia Amendment 203 to the IRC raises the minimum ceiling height for habitable
spaces to 7 ft 6 in, exceeding the base IRC requirement of 7 ft.
**Question 2.** Under the ADA, the clear width of a ramp run serving a public building must be
at least:
A) 30 in
B) 36 in
C) 42 in
D) 48 in
Answer: B
Explanation: The ADA specifies a minimum clear width of 36 in for accessible ramps to
accommodate wheelchair users.
**Question 3.** In plan reading, the symbol “⏚” most commonly represents:
A) Electrical panel
B) Fire extinguisher location
C) Sprinkler head
D) HVAC unit

Answer: C
Explanation: The circle with a dot (⏚) is the standard symbol for a fire sprinkler head on
architectural drawings.
**Question 4.** Which building classification has the highest fire‑resistance rating for structural
elements?
A) Type I
B) Type II
C) Type III
D) Type V
Answer: A
Explanation: Type I construction is fire‑resistive, requiring non‑combustible materials and the
highest fire‑rating for structural components.
**Question 5.** The allowable bearing capacity for a well‑compacted sandy soil is typically:
A) 500 psf
B) 1,500 psf
C) 3,000 psf
D) 5,000 psf
Answer: C
Explanation: Well‑compacted sand usually provides a bearing capacity around 3,000 psf,
whereas clay may be lower and rock much higher.
**Question 6.** An NPDES permit is primarily concerned with controlling:
A) Noise pollution

B) Storm‑water runoff
C) Air emissions
D) Waste disposal
Answer: B
Explanation: The National Pollutant Discharge Elimination System (NPDES) regulates
storm‑water discharges to protect water quality.
**Question 7.** When designing a footing for a wall load of 30 kips on a clay subgrade with a
bearing capacity of 2,000 psf, the minimum footing area should be:
A) 12 sq ft
B) 15 sq ft
C) 18 sq ft
D) 24 sq ft
Answer: D
Explanation: Area = Load / Bearing Capacity = 30 kips / 2 psf = 15 sq ft, but a safety factor of 1.5
is required, yielding 22.5 sq ft → rounded up to 24 sq ft.
**Question 8.** Which deep‑foundation type transfers loads through friction primarily?
A) End‑bearing pile
B) Drilled caisson
C) Friction pile
D) Spread footing
Answer: C
Explanation: Friction piles rely on skin friction along the shaft to transfer loads, unlike
end‑bearing piles that use tip resistance.

**Question 9.** The most common method for waterproofing a basement wall is:
A) Bituminous membrane
B) Polyurethane coating
C) Bentonite panel system
D) Cementitious waterproofing
Answer: D
Explanation: Cementitious waterproofing is widely used for basement walls due to its ease of
application and compatibility with masonry.
**Question 10.** A concrete slump of 4 in indicates:
A) Very dry mix
B) Very stiff mix
C) Normal workability
D) Extremely wet mix
Answer: C
Explanation: A slump of 4 in falls within the typical range (2–4 in) for normal workability in most
structural concrete.
**Question 11.** Air‑entrained concrete is primarily used to improve:
A) Compressive strength
B) Freeze‑thaw durability
C) Slump consistency
D) Setting time
