The design and selection towards an “Effective Vertical Transportation System” starts with early entry into the project, preferably at the concept stage itself.
There isn’t much to differentiate between technology offerings from the major companies. In fact you might not even be able to differentiate between processes.
A well designed and executed vertical transportation system, when badly maintained is a white elephant, or even worse, a dangerous white elephant.
As the building ages, so does the vertical transportation system. It becomes necessary to consider the modernization / replacement of the equipment.
