What documents do you need for a lift condition survey (LOLER, maintenance logs, O&M manuals)?

Useful documents include the latest LOLER Thorough Examination reports and any defect close out records, maintenance logs and service sheets, breakdown history, O&M manuals, drawings where available, and details of any recent upgrades or major repairs. If some records are missing, the survey can still proceed, but conclusions may be limited in those areas.
