Influence of Service Shaft Location on Maintenance Accessibility in Multi-Storey Buildings

Abstract

The study examines the influence of service shaft location on maintenance accessibility in multi-storey buildings, with emphasis on how the positioning of vertical service shafts affects the ease, safety, and efficiency of accessing building services for inspection, repair, replacement, and routine maintenance. Service shafts accommodate important building systems such as plumbing, electrical installations, ventilation ducts, and other service components that require periodic access. Their location within a building can therefore influence maintenance operations, particularly where access is restricted by occupied spaces, fixed finishes, structural elements, or difficult circulation routes. The study will assess the relationship between service shaft location and maintenance accessibility in selected multi-storey buildings. Attention will be given to the position of service shafts in relation to corridors, service rooms, staircases, occupied spaces, wet areas, and other building components. Maintenance accessibility will be assessed based on ease of approach, access distance, working space, visibility of service components, movement of maintenance personnel, availability of access panels or doors, safety, and the ease of carrying out inspection and repair activities. A descriptive cross-sectional research design will be adopted for the study. An appropriate sample of selected multi-storey buildings and relevant maintenance personnel will be selected using a suitable sampling technique. Data will be collected through physical observation, dimensional measurements, service-shaft inspections, building layout assessments, photographic documentation, maintenance records where available, and structured questionnaires or interviews with facility managers and maintenance personnel. The collected data will be analyzed using descriptive statistics such as frequency, percentage, mean, and standard deviation, while appropriate comparative and correlation techniques will be applied to examine the relationship between shaft location and maintenance accessibility. The study is expected to reveal that service shaft location has a measurable influence on maintenance accessibility in multi-storey buildings. Service shafts positioned close to accessible circulation routes and appropriate service areas are expected to provide easier inspection, repair, and replacement of building services. Shafts located within restricted or heavily occupied areas may create difficulties for maintenance personnel, increase access time, disrupt building activities, and make maintenance operations more complex. The effect may also vary according to building height, shaft dimensions, access-panel arrangement, service density, floor layout, and maintenance requirements. The findings will be useful to architects, building services designers, facility managers, maintenance personnel, developers, and other professionals involved in the planning and management of multi-storey buildings. The study may provide practical information for determining suitable service shaft locations that support effective maintenance without unnecessarily disrupting occupied spaces. It may also contribute to building designs that improve service accessibility, reduce maintenance difficulties, and support efficient facility management throughout the building's operational life. The study will conclude by establishing the influence of service shaft location on maintenance accessibility in multi-storey buildings and emphasizing the importance of considering maintenance requirements during the planning and positioning of service shafts. It is recommended that service shafts be located where maintenance personnel can approach and access them safely, with adequate working space and minimal interference with occupied areas. Further studies should examine service shaft planning across different building types, service systems, and maintenance conditions.
