1. Standpipe Requirements in Construction
According to International Fire Code (IFC) 2021, Section 3313.1, a temporary standpipe must be installed when construction progresses above 75 feet from the lowest level of fire department access.
This ensures firefighters have adequate water supply access during high-rise construction.
2. Why the 75-Foot Requirement?
Buildings exceeding 75 feet are classified as high-rise structures, where fire department hose streams may not reach upper levels efficiently.
A standpipe system provides a reliable water source for fire suppression during construction, reducing fire risk.
3. Verification of Other Options
Option A (30 feet) - Incorrect, as standpipes are not required at this height under IFC regulations.
Option B (40 feet) - Incorrect, as this is below the high-rise threshold and does not require standpipes yet.
Option C (55 feet) - Incorrect, as IFC specifically mandates standpipes at 75 feet, not 55 feet.
