Sectors served

Fourteen sectors, each with different demands

A hospital cannot take a bank of elevators out of service the way an office tower can. An airport moving walk runs nearly continuously.

The sector is where the question starts, not where it is answered. Two hospitals on the same street can differ in every constraint that matters — bank layout, machine room access, and what the building can be without while the work runs.

What changes by sector

Shutdown windowsWhen a bank can be taken out of service, and for how long, is what the work is sequenced around.

Traffic patternsCar count and speed follow from an analysis of the building’s own population — not from a table.

Duty cycleWe specify against the duty the building will actually run, rather than the one the catalogue assumes.

Code obligationsEstablished on the equipment, in the machine room and the hoistway, before a specification is written.

Machine mixTraction, hydraulic, escalator, and moving walk are assessed on different parts; the mix changes by building.

Eight sectors, and what changes in each

Every sector places different demands on vertical transportation. We account for how the building actually operates — its traffic patterns, its shutdown windows, its code obligations — before recommending anything.

HospitalsA bank cannot come out of service the way an office tower’s can — bed moves, theatre lists and imaging traffic set the window.
Commercial Office BuildingsLobby waiting time in the morning peak is what a tenant complains about, and what car count is sized to.
UniversitiesDemand arrives in ten-minute peaks between classes and then stops, so an escalator sized to the daily average is undersized twice an hour.
AirportsA moving walk runs nearly continuously, so wear is counted in running hours rather than trips and the maintenance interval follows.
HotelsGuest, luggage and service traffic share the same shafts, and the work has to be sequenced around occupancy rather than around a closure.
Government BuildingsProcurement is competitive and on the record, so the specification has to be biddable by more than one manufacturer.
Residential High-Rise BuildingsOne or two cars serve the whole stack, so one unit out of service is the building’s entire vertical transportation.
Convention CentersEscalators stand idle between events and then carry a full hall in twenty minutes, which is a duty cycle no catalogue table describes.
