Building services maintenance: an outsource service provider selection via scoring model

Abstract

Building services outsourcing has become popular as it gives a peace-of-mind for the firms by contracting operation and maintenance of the building services to an external expert party for an agreed period and for agreed fee. However, the main issue faced by a firm is to select the most suitable outsource. The objective of this study is to identify critical service provider selection factors, in the area of building service maintenance outsourcing in property management and, to construct a scoring model that can be used at the decision making level. We have chosen quantitative/ structured questionnaire survey research approach. Expert views helped to identify the service provider selection factors in the premises and property management sector in Sri Lanka. We deploy Fuzzy Delphi Methods (FDM) to ranking and identifying weights of the service provider selection factors. Then Analytical Hierarchy Process (AHP) model computes the weights of the screened factors by performing pair-wise comparisons. These weighted factors can be used to construct the service provider selection model.
