Defects and Their Influencing Factors of Posthandover New-Build Homes
Publication: Journal of Performance of Constructed Facilities
Volume 29, Issue 4
Abstract
Building defects are an important aspect to address to enhance the quality of homes. However, there is limited knowledge of defects of posthandover new-build homes. This paper aims to examine the profile of building defects in number, type, location, and severity and investigate their influencing factors, including building type, floor area, number of bedrooms, build method, and performance standard. Data were collected using defect records for 327 homes in the United Kingdom (U.K.) during the defects liability period of 12 months posthandover. In total, 3,209 defects were identified and examined. The results indicate that the defect profile of UK post-2006 new-build homes has improved in the number, diversity, and severity of defects. Kitchens and bathrooms remained the two most defective areas. Larger houses were found to be significantly more defective than smaller flats. However, no clear relationship was observed between the defect profile of the dwellings and their build method or performance standard adopted. The findings shed light on the understanding of the profile of building defects and should support their better predictability and control in future practices.
