If it's government regulations then an inspector needs to come over to confirm the work needs to be done, then a supervisor needs to come to confirm the work site complies with Health and Safety Regulations. Only after that's been cleared can the actual repairman be sent, and he needs to confirm the state of the site before doing any work, and then wait 4-6 weeks for parts to arrive. At which point, because it's into a new month the inspector needs to recertify the site, and the supervisor needs to clear Health & Safety again. The repairman can then do the work required, and then calls the supervisor in to make sure that the site has been left it a fit state, which the inspector needs to confirm before opening the elevator for public use.
