To determine the occupant load of a 50,000 gross square foot airport terminal concourse, we use the occupant load factor from 2021 IBC Table 1004.5.
Step 1: Identify the Occupant Load Factor for an Airport Concourse
According to IBC Table 1004.5, the occupant load factor for an airport terminal concourse is 20 sq. ft. per person (gross).
Step 2: Calculate the Occupant Load
50,00020=2,500 occupants\frac{50,000}{20} = 2,500 \text{ occupants}2050,000=2,500 occupants Reference to Fire Inspector Documentation:
1. 2021 International Building Code (IBC) - Table 1004.5 (Occupant Load Factor for Airport Concourses)
20 sq. ft. per person is assigned for airport concourses.
2. 2021 International Fire Code (IFC) - Section 1004.1.2 (Occupant Load Determination) Gross area calculations must follow the correct occupant load factor per IBC Table 1004.5.
Detailed Explanation of Answer Choices:
Option A (Incorrect): 200 is too low based on proper calculations.
Option B (Incorrect): 500 is also too low.
Option C (Incorrect): 1,000 is below the required calculation.
Option D (Correct): 2,500 is the correct calculation based on IBC Table 1004.5.
Thus, the correct and verified answer is: D. 2,500.
