Staircases are important pedestrian routes between different levels. They often also serve as the means of egress from structures and buildings [1]. Because they are constantly subjected to wear and tear due to human and/or goods transportation traffic, it is vital for personnel overseeing the management of facilities to maintain and inspect them, to ensure safety as well as identify any minor or major damage [2]. The identified defects refer to issues concerning a stairway’s general requirements, handrails, slippery access routes and accessibility. The design of escape staircases should provide all occupants with a safe and efficient exit. Accessible refuge areas are also vital for occupants to evacuate in any emergency [3]. Additional information regarding the accessibility considerations for elevators, although maintainability considerations pertaining to vertical transportation are dealt with in the MEP Systems of the building component category.
