• Which of the following is the primary advantage of prefabricated steel

buildings?

• Low fire resistance
• Rapid construction
• High maintenance requirements
• Limited design flexibility
• Rapid construction

Rationale: Prefabricated steel buildings are manufactured off-site

and assembled quickly on-site, significantly reducing construction time.

• What is the common method for joining steel members in prefabricated

buildings?

• Welding
• Riveting
• Bolting
• All of the above
• All of the above

Rationale: Steel members in prefabricated buildings can be joined

using welding, riveting, or bolting depending on design specifications and load requirements.

• Which type of steel is most commonly used in prefabricated building

structures? 1 / 3

• Carbon steel
• Stainless steel
• Aluminum alloy
• Copper
• Carbon steel

Rationale: Carbon steel offers a good balance of strength, cost, and

availability for structural applications in prefabricated buildings.

• In prefabricated steel buildings, what is the primary purpose of a

girder?

• To serve as a decorative element
• To support roof or floor loads
• To insulate the building
• To prevent rust
• To support roof or floor loads

Rationale: Girders are main structural members designed to carry

heavy loads and transfer them to columns or foundations.

• What is the typical foundation type for a prefabricated steel building?
• Raft foundation
• Shallow strip foundation
• Pile foundation
• All of the above depending on soil conditions
• All of the above depending on soil conditions

Rationale: Foundation selection depends on soil type, building load,

and local regulations; shallow or deep foundations may be used.

• Which factor primarily influences the design of a prefabricated steel

building?

• Color of the steel
• Load requirements and environmental conditions
• Distance from the nearest city
• Cost of painting
• Load requirements and environmental conditions

Rationale: Structural design must account for dead loads, live loads,

wind, snow, and seismic forces.

• What protective coating is commonly applied to steel members in

prefabricated buildings?

• Galvanization
• Latex paint 2 / 3

• Wax coating
• Oil coating
• Galvanization

Rationale: Galvanization protects steel from corrosion by applying a

zinc coating, increasing durability and longevity.

• What is the main benefit of using modular panels in prefabricated steel

buildings?

• Increased site labor
• Faster assembly and uniform quality
• Limited customization
• Reduced structural integrity
• Faster assembly and uniform quality

Rationale: Modular panels are pre-engineered for rapid assembly

and consistent quality control.

• Which of the following is NOT a typical component of a prefabricated

steel building?

• Columns
• Girders
• Roof trusses
• Load-bearing masonry walls
• Load-bearing masonry walls

Rationale: Prefabricated steel buildings rely on steel frames rather

than load-bearing masonry walls.

• Which document provides the specifications for steel grades,

dimensions, and tolerances?

• Building permit
• Structural steel code
• Contractor’s license
• Material invoice
• Structural steel code

Rationale: Codes like ASTM or local steel standards define material

specifications and ensure safety compliance.

• What is the recommended slope for a prefabricated steel roof to

ensure proper drainage?

• 0%

B) 1–5%

• 10–15%
• / 3
