ABSTRACT
Values for items (a), (b) and (c) are generally decided early in a building’s design or are already fixed in an existing building. Sometimes, the lift designer will be able to suggest the number of floors in each building zone in order to design a more effective lift installation. Item (c), the express jump, may be nothing more than a few extra metres between the main terminal floor and the first served floor, or could be some distance if the first served floor above the lobby is an express zone terminal floor high in the building. More often than not, items (a), (b) and (c) will literally be ‘set in stone’.
