Building services maintenance: an outsource service provider selection via scoring model
Wanigasinghe, PC; Mahakalanda, I
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.

Risk management in electrical distribution system in Sri Lanka hotel industry
Wanigasinghe, PC; Parera, BAKS; Wijeratne, WMPU
An uninterrupted service throughout the facility is a must for building services in the hotel industry because a large part of guest satisfaction with the hotel depends on building services. However, building services face many different types of failures due to various risk factors. Therefore, a risk management framework is an essential part of the building services of a hotel. In case of hotel buildings, the literature suggests electrical power distribution system (EPDS) to be the key building service which governs all other building services and failure in the EPDS can happen due to maintenance risks, operational risks, assets specific risks and human errors. This research was commenced through a study of three leading five star hotels in Sri Lanka. Based on the research findings, a risk management framework was developed to address risks in EPDS of a hotel facility. The risk management framework was developed based on these findings reveals effective practices that could be used to reduce failure in EPDS. The research also pointed that maintenance risk, unplanned operational risk, asset-specific risk and human errors as the main internal risk factors that lead to failures in EPDS. On the other hand, weather conditions was identified as the uncontrollable external risk factors in the hotel industry, a preventive and a predictive maintenance schedule, planned operations, training and development, and proper asset selection criteria were identified as the main risk management strategies used in the hotel industry. The paper proposed a risk management framework to overcome the identified risks in EPDS in hotel industry which consist of failure mode effect analysis, power monitoring panel and a risk mitigation plan to maintain continuous operations in the EPDS. The findings and recommendations of the study will be useful to those responsible for EPDS operations in the hotel industry for the purpose of reducing services failures.
