The hactl project needed to be sprinkler-protected, and the fire authorities required a two-hour fire resistance rating for the roof trusses. These resulted in two main challenges - how to conceal the sprinkler pipework and how to achieve two hours' fire resistance without affecting the exposed roof truss aesthetic.
A fire safety solution has been developed which combines the two issues. The roof truss members are circular hollow sections used as the sprinkler pipework. Sprinkler heads are connected directly into the roof trusses. High-level sprinkler pipework is not required. Water moving through the roof truss members to feed sprinkler heads will keep roof truss members cool in the event of a fire, avoiding the need for passive protection of the truss members. This seamless integration not only met the fire safety requirements; it also achieved a considerable cost saving.
