Abstract

Lift systems in high-rise buildings are often confronted with problems associated with optimum service delivery. The optimum performance of these systems in public high-rise buildings enhances the efficiency of vertical transportation systems. Time performance parameters like the Average Waiting Time (AWT), Transit Time (TRT), and Time to Destination (TTD) are amongst the key performance indicators for examining the performance of lift systems in high-rise buildings. This study assessed the performance times of lift systems of selected high-rise buildings in Abuja city with the view to enhancing the efficiency of vertical transport systems in buildings. Field measurements on the AWT, TRT, and TTD were performed and a well-structured checklist was used for the collection of relevant data on 14 selected high-rise buildings and 41 lift systems in the Central Business District (CBD) of Abuja city. A digital stopwatch was used to measure the AWT and TRT while TTD was derived from the simple computation of AWT and TRT. All the measured parameters were evaluated against the standard performance requirements for an ideal lift system. Findings from the study show that 100% of the lifts installed in these buildings are traction lift types with 90% having an average rated speed of 1.0m/s. Results from the analysis showed that 85.7% of the buildings have lift systems with AWT above the minimum standard requirement. Significant differences (p<0.05) in the mean values of AWT, TRT, TTD were observed. Based on the findings, the assessed lift systems were considered to perform below the expected standard as the majority of buildings experienced long waiting times. This study has provided performance data for optimizing the service delivery of lift systems in high-rise buildings in Nigeria.
