Therefore, the overall duration of the installation, including delivery, architectural finishes, by others, and Form 5 submission etc...

Rule Of Thumb

 Upto 8 storeys = 12 - 16 weeks

 Upto 15 storeys = 16 - 24 weeks

More Accurately

 2 to 3 storey installation = 3 wks/level

4 storeys and above = 2 wks/level

Test & Commissioning

 Rule of thumb, allow 2 weeks plus 1 day per lift per storey.
