Introductionti★★★★For buildings with special features such as the HongKong Airport, buildings with ih atrium, the designers /engineers may not be able to provide fire safety designfollowing the requirement prescribed in the codes ofpractice.It is very common for the designers / engineers to adoptthe fire engineering approach / performance-based fireengineering design for such buildings.Under the fire engineering approach / performance-based fire engineering design, there are no standardfigures for the design of escape route, width of staircaseetc.However, certain principles need to be considered whenfire Engineering g approach / performance-based fireengineering design is adoptedIDRiM'09 10
