Abstract
Purpose
Defect management is an important segment in building maintenance management. Although defect management requires systemic approach, the purpose of this paper is to focus on the measurement of defects in university buildings based on user perspective.
Design/methodology/approach
The paper reviews related literature and presents the outcome of a survey of 550 university buildings users, derived from a convenience sample from five universities.
Findings
A total of 20 defects were found to be very critical to the building users. Faulty electrical systems, faulty air conditioning system and roof damages were the defects requiring urgent maintenance. Based on the findings, it was concluded that resources be directed towards defects that affect security, safety and comfort.
Research limitations/implications
The list of 32 defects may not be exhaustive, but are indicative of defects that affect university building performance. Because the buildings are not prototypes, some of the findings required adaptation. The conclusions were based on data from five universities.
Practical implications
This study is useful to maintenance organizations in efforts to increase users’ satisfaction, productivity and building performance by guiding resources allocation and at the same time reducing rework, dissatisfaction and waste. The findings would provide feedback and feed forward information and knowledge to the design and construction teams. The study provides a platform to integrate maintenance issues into the design and construction phases of building projects.
Originality/value
There is no such conclusive study on the maintenance of university buildings. Both academics and practitioners can apply the findings to their respective maintenance management scenarios.

Abstract
Purpose
The purpose of this paper is to identify the key aspects of building defects performance cases in relation to the building components focusing on the government-owned buildings and to enhance government’s role to curb the building defects to reoccur.
Design/methodology/approach
The qualitative research method approach was adopted with a total of 5,243 specific building defects identified and accumulated from actual building projects and provided feedback on the defects associated with the Government of Malaysia’s owned buildings.
Findings
This paper statistically validates that building defects are a staid delinquent matter fronting the construction industry in Malaysia. This matter needs to be tacked by all the parties involved in the industry. This paper proposes a factual statistical statement that is proved to be a practical and suitable measurement in correcting building defects and preventing them from reoccurring.
Research limitations/implications
Future research could focus on developing a defect performance measurement on real projects now focusing on private buildings as well.
Practical implications
The defects performance statistical measurement is anticipated to prove the problematic rate of defects occurrence on government-owned structures, as the key elements on the national defect preventive strategy which have to be taken into account.
Originality/value
The outcome of this paper is significant in its own right and serves as a platform for future research in this area.

Abstract
Purpose
The largest share of a building maintenance budget goes towards preventing or repairing building defects. Also, building defects shorten a building’s lifetime, impact the user’s safety and health, prevent the buildings from performing their functions well and repairing building defects generates waste. Therefore, this study aims to specify the factors that affecting the number of building defects and how to reduce their negative impacts.
Design/methodology/approach
A case study was used as a research strategy and convergent parallel mixed methods were used as research design. Quantitative and qualitative data were collected concurrently, followed by independent analyses of the quantitative and qualitative data, and then merged the two sets of results according to the procedure of using the convergent parallel design. Descriptive statistics analysed quantitative data, whilst qualitative data was analysed by the content analysis technique.
Findings
The findings of this study explored the factors that affect the number of defects in buildings, the significant factors were related to the building’s life cycle in terms of design, construction, operation and maintenance phase; relevant attributes were construction teams, building users and maintenance teams. The study also addressed the approaches to minimise the negative impacts of those factors. Their negative impacts mainly contributed to increased building defects that increase maintenance costs, affect users’ safety and health, reduce buildings’ lifespan and cause environmental impact due to resource extraction.
Originality/value
The existing studies have not adequately addressed the significant factors that affect the number of building defects. Also, emerging technologies and environmental sustainability considerations related to building defects have not been linked in previous related work. Therefore, the present study has contributed to filling this gap.

Abstract
Purpose
A building deteriorates over time due to aging, wear and tear, and inadequate maintenance. Building diagnosis requires a sound knowledge of engineering, building defects, and detection tools to assess the condition of a building. The physical deterioration of a building reduces its ability to perform its intended function, while environmental deterioration influences the comfort and health of building occupants. This study presents a multi-tiered framework for the inspection of building elements and the environmental conditions of a building.
Design/methodology/approach
A three-tiered building inspection framework is proposed in this study, which consists of the following: Tier-I—a preliminary inspection, Tier-II—a detailed inspection, and Tier-III—an expert investigation. Each tier of inspection assesses the severity of building defects using different technologies for different levels of inspection.
Findings
Proposed multi-tier inspection framework is tested and implemented on a case study. Results were promising, with organized data management on a common platform for both physical and environmental condition inspection having the potential to save time.
Originality/value
The application program developed for the implementation of structured multi-tiered building inspection provides better documentation and data management for building inspection data that can save time involved in manual data operations in traditional paper-based processes.

Abstract
Purpose
The issue of building defects is a growing concern that affects all major construction stakeholders as a result of costs and time implications of reworks. The magnitude of the problem is severe with statistics highlighting defects often result in 4% of the total cost of construction of a building. Despite the importance of this problem, studies have seldom considered development of systematic approaches to enhance the quality control process in construction.
Design/methodology/approach
Building defects is a growing concern that affects all major construction stakeholders because of costs and time implications of reworks. Magnitude of the problem is severe with statistics highlighting defects often result in 4% of the total cost of construction of a building. Despite the importance, studies have seldom considered development of systematic approaches to enhance the quality control process in construction.
Findings
Results indicated that poor workmanship is the main cause of building defects and incomplete works is a frequently detected defect type. Results categorised defects based on cost and frequency to identify the severity. Findings also identified four focus areas including control measures, technology use audit and inspections and promotion of best knowledge.
Research limitations/implications
The study lacks generalisation as it covers only Victorian scenario and further studies are needed to generalise the findings.
Originality/value
The study provides a deeper understanding of the challenges currently facing the residential construction industry in Victoria, Australia, and underlines the need for developing quantitative models and methodologies to improve current processes, practices and policies for effective defects minimisation in Victoria, Australia. The systematic methodological framework can also be adopted by researches across the globe to effectively analyse the options for minimising residential building defects.

Abstract
Purpose
Hospital building maintenance management constitutes a pertinent issue of global concern for all healthcare stakeholders. In Malaysia, the maintenance management of hospital buildings is instrumental to the Government’s goal of providing efficient healthcare services to the Government's citizenry. However, there is a paucity of studies that have comprehensively explored all dimensions of hospital building defects in relation to maintenance management. Consequently, this study seeks to evaluate the defects of hospital buildings in Malaysia with the aim of proffering viable solutions for the rectification and prevention of the issue.
Design/methodology/approach
The study utilised a quantitative approach for data collection.
Findings
The findings indicated that cracked floors, floor tile failures, wall tiles failure, blocked water closets, and damaged windows were some of the flaws that degrade hospital buildings. The study’s outcomes reveal that defects not only deface the aesthetic appearance of hospital buildings but also inhibit the functionality of the buildings and depreciate the overall satisfaction.
Research limitations/implications
Considering the indispensable role of hospital buildings in the grand scheme of healthcare service provision and ensuring the well-being of people, the issue of defects necessitates an urgent re-evaluation of the maintenance management practices of hospital buildings in Malaysia. Previous studies on the maintenance management of hospital buildings in Malaysia have focused primarily on design, safety, and construction.
Practical implications
This is particularly important because defects in hospital buildings across the country have recently led to incessant ceiling collapses, fire outbreaks, ceiling, roof collapses, and other structural failures. These problems are typically the result of poor maintenance management, exacerbated by poor design and construction. These disasters pose significant risks to the lives of hospital building users.
Originality/value
This study offers invaluable insights for maintenance organisations and maintenance department staff who are genuinely interested in improving hospital buildings’ maintenance management to optimise staff's performance and enhance the user satisfaction of hospital buildings in Malaysia and globally.

Abstract
By adopting a condition‐dependent approach to maintenance, facility managers can exercise control over the desired maintenance performance levels and costs. The practice of condition assessment by building inspectors yielded variable results due to subjective perceptions of inspectors. Nowadays well‐trained building inspectors are able to manage condition surveys and provide property managers with objective, reliable information about performance loss and defects in building components. The implementation of various performance levels in planned maintenance requires not only the standardisation of the condition assessment method, but also the related planning methodology. This paper describes the findings from research in the Netherlands which examined the methodology of condition assessment of building components using a six‐point condition scale. Different categories of performance loss in maintenance are distinguished and linked to different kinds of maintenance activities.

Abstract
Purpose
The current maintenance management method has affected the efficiency of the building facility management at Polytechnics. Many issues such as poor service delivery, inadequate finance, poor maintenance planning and maintenance backlogs have emerged due to the usage of conventional method application (paper-based form and unsystematic database. The purpose of this paper is to review existing literature and case studies project of the technologies in maintenance management at Polytechnic, and subsequently to identify the challenge in improving the current maintenance management technologies.
Design/methodology/approach
The purpose of this paper is to review existing literature and case studies project of the technologies in maintenance management at Polytechnic, and subsequently to identify the challenges of information and communication technology (ICT) implementation for strategic defect diagnosis and decision-making in improving the current maintenance management technologies. Eight Polytechnics are selected on the basis of the major problems of using the conventional method in the comparison to investigate the maintenance management practices in each Polytechnic. There are around 32 Polytechnics in Malaysia and most are using conventional methods.
Findings
The findings reveal the need for a more sophisticated maintenance management system that provides guidelines for decision-making processes with the implementation of ICT. The interview results also reveal irregularities within the Malaysian Polytechnics’ maintenance management database. The system architecture and the information system prototype are presented to integrate the information database and maintenance management processes in improving the building diagnosis approach and decision-making process for managing building maintenance.
Originality/value
This new system is expected to become the successful technology in assisting the maintenance contractors, clients and developer for effective management of maintenance defects at Polytechnic.

Abstract
Purpose
Building defects are becoming recurrent phenomena in most high-rise buildings. However, little research exists on the analysis of defects in high-rise buildings based on data from real-life projects. This study aims to develop dashboards and models for revealing the most common locations of defects, understanding associations among defects and predicting the rectification periods.
Design/methodology/approach
In total, 15,484 defect reports comprising qualitative and quantitative data were obtained from a company that provides consulting services for the construction industry in Victoria, Australia. Data mining methods were applied using a wide range of Python libraries including NumPy, Pandas, Natural Language Toolkit, SpaCy and Regular Expression, alongside association rule mining (ARM) and simulations.
Findings
Findings reveal that defects in multi-storey buildings often occur on lower levels, rather than on higher levels. Joinery defects were found to be the most recurrent problem on ground floors. The ARM outcomes show that the occurrence of one type of defect can be taken as an indication for the existence of other types of defects. For instance, in laundry, the chance of occurrence of plumbing and joinery defects, where paint defects are observed, is 88%. The stochastic model built for door defects showed that there is a 60% chance that defects on doors can be rectified within 60 days.
Originality/value
The dashboards provide original insight and novel ideas regarding the frequency of defects in various positions in multi-storey buildings. The stochastic models can provide a reliable point of reference for property managers, occupants and sub-contractors for taking measures to avoid reoccurring defects; so too, findings provide estimations of possible rectification periods for various types of defects.
