What is true regarding missing fire stopping in construction?

Missing fire stopping in construction refers to gaps or voids in the fire-resistive barriers that are designed to prevent the spread of fire within a building. This is particularly relevant in platform construction, which is a common method in residential and commercial building practices where wooden frames are built up layer by layer. In this type of construction, there are often many horizontal and vertical cavities that can allow fire to travel more readily between floors and through walls if fire stopping measures are not implemented appropriately.

In platform construction, the likelihood of missing fire stopping increases due to the nature of the assembly processes and the potential for oversight during the installation of insulation and wall systems. Ensuring that fire stopping is properly installed is crucial for the safety and integrity of the building, as it plays a vital role in maintaining fire ratings.

This understanding highlights why the statement regarding its commonality in platform construction is accurate; it recognizes a specific vulnerability in a prevalent construction method that builders and inspectors must remain vigilant about.
