Defect characterisations in the Malaysian affordable housing

Abstract

Purpose

The 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/approach

With 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.

Findings

The 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 implications

The 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/value

This 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.
