The position of central escalators shapes circulation through an atrium or concourse, directing people towards particular routes on each floor. Their arrangement should follow the building’s intended passenger flow, with enough space at each landing for people to move clear of the steps. Confirm the applicable National Construction Code requirements for projects in Australia with the building surveyor before fixing the layout.

Escalators and building circulation

Commercial escalators need to match the operating demands of the site, not simply the distance between floors. Specify the expected hours of use and peak passenger demand so the equipment can be assessed against its intended duty. Allow for maintenance access in the design: an escalator that fits the floor opening may still be difficult to service if access to its machinery is obstructed.

What is a flat escalator?

A flat escalator usually means a moving walkway: a continuous passenger conveyor rather than a flight of moving steps. Use the term ‘moving walkway’ in the specification and state the route’s length and gradient.

Can an escalator provide the only accessible route between floors?

No, an escalator does not replace an accessible route for wheelchair users. Provide an appropriate alternative, such as a passenger lift, and confirm the access provisions with the project’s access consultant.

How should an existing escalator be assessed for replacement?

Ask a vertical transport specialist to inspect the installation and establish whether the existing supports and floor openings can accommodate replacement equipment. Check how removal and installation will affect adjoining finishes and access through the building.
