What does a developer check before selecting an elevator supplier?
They check capacity and speed against the traffic study, shaft and pit dimensions against the building, and code compliance for the jurisdiction. Then maintenance terms, because the service contract usually outlives the installation contract by decades and costs more.
A developer is choosing equipment whose maintenance contract will bind the building's owners for twenty years.

Questions suppliers ask
Should maintenance pricing be discussed before installation?
It should be published, or at least explained, because it is most of the lifetime cost. Buyers increasingly evaluate installation and maintenance together, and a supplier who is transparent about the long relationship wins against one who is quiet about it.
How much does proprietary technology matter to buyers?
Increasingly a great deal, because it determines whether the building can ever change maintenance provider. Stating plainly which components are proprietary and what a third party can service is unusual and builds trust with owners who have felt locked in.
What does an architect need earliest?
Shaft, pit and headroom dimensions, machine room requirements and structural loads. These fix the building design, so the supplier whose figures are available at concept stage is frequently the one designed in — often before any commercial conversation.
