Maintainability factors for robust maintainance integrated design (R-MInD) in building design

Abstract

Building maintainability considerations relate to the extent to which the building maintenance tasks could be seen as being achievable. The purposes of incorporating good maintainability considerations into building designs are to achieve high building performance, ease day-to-day housekeeping tasks, make the building adaptable for future needs and maintain a stable usage cost throughout the building’s design life. This paper identifies the factors suitable for building maintainability interaction evaluation for a robust building design. The evaluation will be used as a holistic evaluation of variable interaction during operational stage, to reduce future maintenance difficulties and cost. The maintainability interaction evaluation has a multidimensional diagnosis system which consists of controlled and uncontrolled factors. The data collection method in this research includes an expert panel interview using prepared semi-structured interview questions and a questionnaire survey to identify the maintainability factors in fulfilling the maintenance-related needs of the building. This research identifies maintainability factors by applying partial least square structural equation modelling (PLS-SEM) technique. From this research, it is found that the controlled factors are conformance and compliance to regulation and standard; and building services integration while the uncontrolled factors are space planning and, material and equipment selection.
