“…However, because the functional performance of a building is the ultimate interest of the users, they are “competent” to evaluate the “visible” defects in the buildings because the defects affect the occupants. Many studies on defect analyses in buildings have been conducted from the building owners'/users' perspectives (Zalejska-Jonsson and Hungria Gunnelin, 2019; Lee et al , 2018; and Olanrewaju et al , 2017). The fundamental essence of this research is to identify the defects in affordable housing through a questionnaire instrument based on the users' perspectives.…”

“…A survey conducted on the 48 residential building in South Korea identified 755 defects in the buildings. Zalejska-Jonsson and Hungria Gunnelin (2019) reported a high number of cases of defects in Swedish residential buildings. In fact, a recent survey in the UK by the HomeOwners Alliance and BLP Insurance revealed that about 90% of owners of new-built homes supported “snagging retention” because of the increase in the number of buyers reporting problems with their new homes (HomeOwners Alliance (2019)).…”

PurposeThe successive Malaysian government aims to provide housing to households earning the median income and below. However, there has been continuous criticism and complaints from the media and literature on the magnitude of the defects in affordable housing. Therefore, this research has investigated the defects in affordable housing for the users’/occupants' perspectives.Design/methodology/approachWith a response rate of 69%, the research developed a questionnaire instrument that included twenty-one defects in buildings based on literature and observation. These were scored on a 5-point Likert scale ranging from very common to least common. Twelve causes of defects measured on a five-point scale were included in the survey. Thirteen additional items that had to do with remedial actions to reduce defects were included. These were scored on a 5-point Likert scale ranging from strongly agree to least agree. The survey forms were administered to all the 152 home occupants in a Program Perumahan Rakyat (PPR) housing estate through hand delivery in a northern state in Malaysia.FindingsThe data revealed that broken doors, damaged roofs, damp walls and broken tiles in rooms were the most common defects in the housing development. It was found that defects in the buildings were caused by poor workmanship, defective materials, poor designs and bad weather. Additionally, to rectify the defects, adequate supervision is required during maintenance, the repairs must be conducted on time and there is a need to have competent maintenance organisations. Through factor analysis, the 21 defects were structured into six factors, the 12 causes were grouped into 5 factors and the 13 remedial actions were grouped into 6 factors.Practical implicationsThe information on the nature, degree and kinds of defects from the users' perspectives will dictate when repair work is to be undertaken and allow future work to be programmed and financed as part of a maintenance rolling programme.Originality/valueThis research focused specifically on “Program Perumahan Rakyat” housing development. Furthermore, none of the previous research on defects conducted attempted to categorise the defects in the buildings. The categorisation is very important for systemic decision-making because there are continuous interactions amongst the defects, causes and remedial actions.

“…Defects hinder the functional performance of the buildings and services. Defects influence the occupants'/clients' satisfaction and lead to disputes and litigation amongst clients/users, developers and maintenance organisations (Lee et al, 2018;Zalejska-Jonsson and Gunnelin, 2019;Olanrewaju and Lee, 2022). Poor quality can manifest within a structure, fabric, services and other facilities.…”

PurposePoor quality in building projects is high and increasing. Poor quality can increase the cost of a building by up to more than 50% and can delay a project by up to 50%. This research investigated the poor quality of building elements/components.Design/methodology/approachThe site operatives were requested to rate the frequency of poor quality in 25 building elements/components. The frequencies of the poor quality were scored on a five-point Likert scale, ranging from least often to extremely often. The survey forms were administered to construction site operatives by hand delivery.FindingsThe data revealed that poor quality occurred in more than 80% of the building projects completed. Approximately 40% of the cost of a building project is attributed to poor quality. In total, 70% of the respondents measured the poor quality of building elements as being high and frequent. The size and frequency of poor quality are higher in concrete, plaster, brick, foundations and roof trusses.Practical implicationsThe research findings would help to reduce claims, disputes, maintenance costs and waste on sites.Originality/valueThis research provides fresh information on poor quality in building projects and provides a systemic process for anticipating poor quality in building projects. The findings also provide an option to increase maintenance span and a means to reduce claims and disputes in the construction sector.

“…One way to objectively measure the quality of buildings is by measuring the occurrence of defects in the final product [12,13] and investigating how their occurrence impacts customer satisfaction [14]. This study adopted the definision of a defect as "a shortcoming or falling short in the performance of a building element" [15], and categorizes defects into three categories: (1) technical, when the functional performance of a structure or element is decreased due to material or workmanship problems; (2) aesthetic, when there is a problem with the appearance of an element, but its functioning is not affected; and (3) functional, when elements in the residential unit do not function as planned. All defects have some impact on buildings; however, it is worth noting that technical defects might affect the health and safety of the users and are usually related to lack of compliance to regulations, whereas functional and aesthetic defects might have psychological impacts but do not compromise the health and safety of the users.…”

CBA-Based Evaluation Method of the Impact of Defects in Residential Buildings: Assessing Risks towards Making Sustainable Decisions on Continuous Improvement Activities

et al. 2021

Evaluating the impact of defects in buildings and ranking the most impactful ones enables construction companies to better choose which paths to take in light of continuous improvement activities to support more sustainable decisions regarding the design and operation of buildings. As a result, the risks of the different choices are more clearly identified while assessing all tangible and intangible aspects of residential building defects in a structured way. Although recent studies on managing construction defects in residential buildings have focused on monetary losses associated with maintenance activities based on the defect’s frequency and severity, these studies do not take into account the levels of customer satisfaction. To address this gap, this paper proposes a novel evaluation method of the impact of defects to support decision-making in managing defect occurrences in residential buildings. The goal is to rank the defects’ impact based on a combination of some critical aspects: frequency of occurrence, financial considerations on repairing such defects, the impact that these defects have on customer satisfaction, and the cost and complexity of preventing and minimizing these defect occurrences through continuous improvement activities. The method consists of a structured set of steps that use data from technical assistance departments and customer satisfaction surveys, where information about the users’ level of satisfaction and the occurrence of defects is available. In this paper, data obtained from a construction company were used to test and validate the proposed method. The method also examines the challenges and barriers associated with the technique and points out that difficulties in acquiring reliable data are a bottleneck for making conscious and sustainable decisions to address construciton defects. Moreover, the case study results highlight essential capabilities needed by companies to correctly assess the impact of defects, such as correctly logging data in a structured database and having skilled personnel to verify defects users might have complained about. The paper ends by proposing a set of guidelines to use the method and stressing that structured methods for decision-making are crucial to analyze construction defects in a structured way while also incorporating the user’s perspective. The proposed method is expected to improve sustainable managerial decisions where economic, environmental, social, and technical risks can be accounted for to enhance the quality of projects from the customer’s perspective. Such analysis can help optimize and prioritize the use of resources and minimize the economic impact of activities on the construction company.
