Significant Characteristics of Scheduled and Condition-Based Maintenance in Office Buildings

AbstractSustainability of buildings is one of the main aims in the construction industry. In achieving sustainability, maintenance of buildings and its facilities, which include planning, implementation, and outcome of maintenance activities, becomes an important criterion. This paper aims to identify the significant characteristics of scheduled and condition-based maintenance in office buildings through reviews of relevant literature and a questionnaire survey. The significance of the characteristics was identified through ranking analysis. A semistructured interview was conducted to obtain further details on the characteristics and measures to enhance efficiency of the characteristics. The findings reveal that the dominant characteristics for scheduled maintenance include quality of spare part and material, the level of labor skill and knowledge, and budget allocation for maintenance labor, whereas for condition-based maintenance, the dominant characteristics are the level of manager skill and knowledge...

Optimising maintenance cost performance with skilled technicians

Purpose – High-maintenance cost is the common issue in building industry due to low service quality of maintenance management in Malaysia. Lack of preventive measure is the problem that implicates poor maintenance performance. Scheduled maintenance is suggested to improve the maintenance performance.

Thus, the purpose of this paper is to identify the aspects of skilled technician to be concerned in maintenance management, as well as to establish the relationship between the aspects and maintenance cost performance. Design/methodology/approach – A quantitative approach is adopted and carried out through questionnaire survey. Furthermore, descriptive analysis and correlation analysis are used to analyse the research data. Findings – The literature review identifies three aspects of skilled technician to be concerned in maintenance management. Then, research result demonstrates that the s...

Enhancing building maintenance cost performance with proper management of spare parts

Purpose – Scheduled building maintenance requires appropriate and adequate spare parts to replace existing parts on a regular basis. Management of spare parts is seen as an important criterion to ensure the efficiency of scheduled maintenance. The purpose of this paper is to identify the contributors of spare parts management and investigate the relationship between these contributors and maintenance cost performance. Design/methodology/approach – This research adopted a quantitative approach, which utilised questionnaire surveys to study the relationship between the contributors of spare parts management and maintenance cost performance. The data were analysed through descriptive analysis, correlation, and regression analysis. Additionally, a case study was examined to validate the results obtained from the survey. Findings – The results of this research demonstrated that the quality of spare parts (QSP), budget allocation for acquisition of spare parts, and level of stocks were significantly correlated ...

Influences of key stakeholders’ involvement in maintenance management

Purpose Proper maintenance management ensures a long-term investment and provides a support function in business continuity to achieve organisational goal. However, inadequate involvement and participation of key stakeholders in maintenance management limit the continuous improvement of maintenance performance. Currently, there is a lack of studies about the influence of key stakeholders’ involvement in maintenance. Thus, the purpose of this paper is to deal with enhancement of maintenance management through the involvement of key stakeholders. Design/methodology/approach This research adopted a mixed method approach to determine the relationship between involvement of key stakeholders in maintenance management and maintenance effectiveness. The approach comprised of literature review, questionnaire survey and semi-structured interviews. Findings This research suggests a positive correlation between involvement of maintenance manager (MM), maintenance staff, organisation, user and maintenance service provider (SP) in improving the effectiveness of maintenance management. The logistic regression analysis indicated that the involvement of MM and SP are significant predictors of maintenance effectiveness. The research further identified that there was a lack of involvement of the user and SP in maintenance management. Originality/value The research demonstrated that all key stakeholders should value the important roles of their participation in maintenance management to ensure an optimum return on a long-term investment. To create the awareness for the involvement of key stakeholders in building maintenance, studies on the advantages of participating in building maintenance and the impacts of ignorant towards building maintenance can be beneficial to the industry.

Relationship between Predetermined Maintenance Interval and Maintenance Performance

Lack of preventive measure is currently the problem that implicates poor maintenance outcome. Scheduled maintenance is claimed as a maintenance strategy to tackle the problem. However, the effectiveness of scheduled maintenance can be greatly influenced by the length of predetermined maintenance interval. Thus, this paper aims to study the relationship between length of predetermined maintenance interval and maintenance performance. The literature review identifies the length of predetermined maintenance interval as an importance characteristic of scheduled maintenance strategy. A quantitative approach is adopted and carried out through questionnaire survey. Subsequently, descriptive analysis and correlation analysis are used to analyse the collected data. Then, research result demonstrates that the length of predetermined maintenance interval is significantly correlated to the maintenance performance. The length of predetermined maintenance interval must be considered in maintenance planning and execution. The research recommends continuous monitoring or regular inspection of building systems and components to identify their condition and update the length of predetermined maintenance interval regularly. Consequently, the effective maintenance execution helps to avoid systems failure occurs and optimises maintenance performance.

Maintenance of high-rise residential buildings

Preventive maintenance is an effective maintenance strategy to ensure the constant and efficient usage of building systems and their components. The reactive-based maintenance as the main strategy in high-rise residential buildings is a concern as the maintenance output resulting from the strategy could not achieve the standard level of performance. The purpose of this paper is to identify the characteristics of preventive maintenance and establish the relationship with maintenance performance in high-rise residential buildings.,The characteristics of preventive maintenance and maintenance performance parameters were identified through the literature review. A quantitative approach was adopted, where a questionnaire was distributed to the maintenance personnel of high-rise residential buildings. Then, ranking analysis and correlation were conducted to produce findings that help to achieve the research objectives.,The research findings indicate that there are seven maintenance characteristics significantly correlated with maintenance performance indicators (maintenance costs deviation, time variance of maintenance work, customer service and downtime rate). It is recommended that these characteristics are considered during the execution of preventive maintenance as they have a significant effect on the maintenance performance.,The extensive literature suggests the relationship between the characteristics of preventive maintenance and maintenance performance, but is still questionable. Thus, this research investigates the relationship between preventive maintenance characteristic and maintenance performance for high-rise residential buildings in Malaysia. The findings of the research can act as a guide for maintenance personnel to optimise maintenance performance by focusing on the highlighted preventive maintenance characteristics.

Maintenance of lift systems affecting resident satisfaction in low-cost high-rise residential buildings

Purpose Providing quality low-cost high-rise residential housing for poor households remains a major concern worldwide, and especially in Malaysia. Despite government effort to maintain the quality of the housing through the Housing Maintenance Program and 1Malaysia Maintenance Fund Program (TP1M), the maintenance industry is still faced with serious housing quality problems in terms of facilities, one of which is the lift system. As the most expensive and important transportation system in a high-rise building, a lift system requires regular maintenance and inspection in order to provide safe and effective service to occupants. Unfortunately, most lift systems in Malaysia are not effectively maintained. Therefore, this research attempts to examine contributing factors to the breakdown of lift systems, which greatly affects resident satisfaction in low-cost high-rise residential buildings. Design/methodology/approach Semi-structured interviews were conducted with three stakeholders involved in maintenance...
