Period of elevator replacement construction
It generally takes 30 days to manufacture an elevator as of the determination of specifications and takes another 20 days for the demolition, installation and commissioning. In case of the presence of multiple elevators on site, it is likely to take 22 days to manufacture the first one followed by self-inspection and consultation, then move to the next one. (However, governmental inspection might be performed separately.)
※ However, construction period is subject to change depending the site conditions and construction coverage.
