What is the fire resistance rating of Type II construction according to PD 1096?

The fire resistance rating of Type II construction, according to PD 1096, is correctly identified as 1 hour. This type of construction is characterized by non-combustible materials and requires that the structural elements have a certain degree of fire resistance to enhance safety during a fire incident. The 1-hour rating indicates that the building's structural components are designed to withstand fire exposure for at least one hour before failing. This is an important consideration for ensuring that occupants have adequate time for evacuation and that fire services can effectively respond to the incident. Understanding the fire resistance ratings is essential for compliance with safety regulations and for designing buildings that can minimize risks associated with fire.
