Question 1

What does 'Type I-A' construction classification indicate under the IBC?

Accepted Answer

The most fire-resistive construction type with non-combustible materials

Answer

Type I-A is the highest fire-resistance construction type, requiring non-combustible materials with 3-hour rated structural frame and 2-hour floor/ceiling assemblies.

Question 2

The Americans with Disabilities Act (ADA) requires a maximum slope of _____ for an accessible ramp.

Accepted Answer

1:12 (8.33%)

Answer

ADA Standards require accessible ramps to have a maximum slope of 1:12 (one inch of rise for every 12 inches of horizontal run), equivalent to 8.33%.

Question 3

What is the primary purpose of a 'fire sprinkler system' in a building?

Accepted Answer

To control fire growth and suppress fire to allow safe occupant egress

Answer

Sprinkler systems are designed to control fire growth and limit heat release, buying time for occupant evacuation — not necessarily to extinguish fires completely.

Question 4

Under the IBC, 'travel distance' in means of egress refers to:

Accepted Answer

The maximum walking distance from any point in a floor to the nearest exit

Answer

Travel distance is the measured walking path from the most remote point in a room or floor to the nearest exit, with IBC maximums varying by occupancy and sprinkler status.

Question 5

What does 'occupant load' determine in building code compliance?

Accepted Answer

The number of people a space is designed to accommodate, which governs exit width, number of exits, and plumbing fixture counts

Answer

Occupant load is calculated by dividing floor area by the occupant load factor for that use, and it determines required egress capacity, number of exits, and sanitary facility counts.
