Elevator Maintenance Experts on UNC Outages - The Daily Tar Heel

Questions about elevator outages at a large university campus (UNC-Chapel Hill) Hi everyone — I’m a student journalist with The Daily Tar Heel working on a story about frequent elevator outages across the University of North Carolina at Chapel Hill campus. I’m hoping to get some industry context from people familiar with elevator maintenance and operations. For context: between Aug. 1 and Dec. 31, 2025, UNC reported 374 elevator outages across 368 elevators maintained by the university. (An “outage” here refers to elevators being taken out of service for repair; durations vary.) According to UNC Media Relations: >"ModprosElevatoris responsible forrepair efforts which can sometimes be delayed due to hard-to-find parts for some of the older buildings and equipment on our historic 230+ year old campus." Beyond that, public information is fairly limited. I’d appreciate any insight on the following: Is anyone familiar with Modpros Elevator and how they typically operate on large campuses or institutional facilities? What are the most common causes of elevator malfunctions or outages in commercial or university buildings (e.g., door systems, controls, aging equipment, environmental factors)? From an industry standpoint, does a figure like 374 outages over five months across \~370 elevators fall within a normal range, or would it generally be considered higher than expected? What factors most often contribute to repair delays today? Are parts availability, supply-chain issues, or technician shortages still common challenges, especially for older equipment? I’m on a tight deadline and still learning the technical side of elevator systems, so any perspective or general guidance would be incredibly helpful. Thanks in advance!
