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.

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.

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.

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.

With increased architectural, design and functional requirements and complexities, maintaining a modern building can easily become a costly affair. There is much evidence in the literature review as well as from the factual data, showing the significant increase of the maintenance budget in the recent past. This is due to the fact that, these complexities eventually generate many deficiencies and difficulties and, in turn, creates a tremendous maintenance workload and an undue budget. Therefore, the purpose of this paper is to discuss factors related to such issues in the form of risks involved in the maintainability of buildings and further, explore several strategies and industry actions at the industry level to resolve this burning problem. This paper is focused to address the condominium properties.

This approach of investigation of the risk factors was based on exploring the causes of existing defects and problems, which tend to lower the maintainability. Existing literature, site observations/interviews and questionnaire surveys were used to gather the required data.

There are 13 number of critical maintainability problems, 43 respective factors as “maintainability risk” factors and 12 subsequent industry actions for better maintainability, in the findings. In addition, nine maintainability strategies are explored based on the relevant risk conditions to enhance the maintainability at the organizational/project level and three industry motivators are extracted from the relevant industry actions. A simplified framework for maintainability is proposed based on the strategies and the industry actions.

The data collection has to be limited to the Colombo metropolitan region due to limited resources.

The paper provides useful information to the designers, clients, facilities managers/maintenance managers and users, on maintainability issues related to condominiums. This information highlights the important risk conditions, strategies and industry motivators in order to minimize these problems. These findings may provide an opportunity to promote “highly maintainable buildings for the future”.

The purpose of this paper is to evaluate the risks of building defects associated with rapid advancement of “green” construction technologies. It identifies the methods adopted by the sector for the determination of pre-construction defects that are framed within the context of, traditional; scientific; and professional design approaches. These are critically evaluated and utilised in attempts to mitigate defects arising from diffusing low carbon construction innovations.

The paper takes the form of an evaluative literature review. Polemic in orientation, the paper critically compares two periods of time associated with rapid advancement of innovation. The first, the post-Second World War housing boom is synonymous with a legacy of substandard buildings that in many cases rapidly deteriorated, requiring refurbishment or demolition shortly after construction. The second, is today’s “green” technology “shift” with its inherent uncertainty and increased risk of latent building defects and potential failure to deliver meaningful long-term performance. Central to this is an exploration of the drivers for innovation, and subsequent response, precautionary measures initiated, and the limitations of institutionalised systems to identify and mitigate defects. Similarities and differences between these historical periods frame a discussion around the theoretical approaches to defects and how these may be limited in contemporary low carbon construction. A conceptual framework is presented with the aim of enhancing the understanding for obviation of defects.

Sufficient commonality exists between the periods to initiate a heightened vigilance in the identification, evaluation and ideally the obviation of defects. Design evaluation is not expressly or sufficiently defect focused. It appears that limited real change in the ability to identify defects has occurred since the post-war period and the ability to predict the performance of innovative systems and materials is therefore questionable. Attempts to appraise defects are still embedded in the three principle approaches: traditional; scientific; and professional design. Each of these systems have positive characteristics and address defect mitigation within constrains imposed by their very nature. However, they all fail to address the full spectrum of conditions and design and constructional complexities that lead to defects. The positive characteristics of each system need to be recognised and brought together in an holistic system that offers tangible advantages. Additionally, independent design professionals insufficiently emphasise the importance of defect identification and holistic evaluation of problems in design failure are influenced by their professional training and education. A silo-based mentality with fragmentation of professional responsibility debases the efficacy of defect identification, and failure to work in a meaningful, collaborative cross professional manner hinders the defect eradication process.

Whilst forming a meaningful contribution to stimulate debate, further investigation is required to tangibly establish integrated approaches to identify and obviate defects.

The structured discussion and conclusions highlight areas of concern for industry practitioners, policy makers, regulators, industry researchers and academic researchers alike in addressing and realising a low carbon construction future. The lessons learned are not limited to a UK context and they have relevance internationally, particularly where rapid and significant growth is coupled with a need for carbon reduction and sustainable development such as the emerging economies in China, Brazil and India.

The carbon cost associated with addressing the consequences of emerging defects over time significantly jeopardises attempts to meet legally binding sustainability targets. This is a relatively new dimension and compounds the traditional economic and societal impacts of building failure. Clearly, blindly accepting this as “the cost of innovation without development” cannot be countenanced.

Much research has been undertaken to evaluate post-construction defects. The protocols and inherent complexities associated with the determination of pre-construction defects have to date been largely neglected. This work attempts to rectify this situation.

Research on housing defects has limited its enquiry to the classifications of defects, potential impact of defects, and their detection and remediation during construction and the builder’s liability period, without considering the warranty period. The purpose of this paper is to better understand which impacts of defects are perceived as important by the key stakeholders involved in their detection and remediation over the construction, builder’s liability and insurer’s warranty periods.

The questionnaire survey approach was used. The questionnaire distribution list was drawn from the UK’s largest warranty provider (WP) and approved inspector’s records. The questionnaire was distributed to 2003 people, receiving 292 responses, a response rate of 15 per cent.

This research challenges the assertion that the house building industry (i.e. house builders (HBs), building inspectors and WPs) is predominantly cost focussed and finds that the potential impact of defects on home occupants (HOs) are their primary concern. In contrast, the HOs’ appear solely focussed on the disruption defects caused on their daily lives and perceive a lack customer focus in the house building industry.

This study provides empirical evidence of the contrasting view of the house building industry and HOs with respect to the prioritisation of the impacts of defects. Further, this research offers HBs an alternative approach to determine which defects should be targeted for reduction purposes which may lead to improved levels of customer satisfaction.

The purpose of this paper is to investigate the current practices of the early facilities management (FM) involvement during the design development and review stages (DDRS), and recommend activities aimed at achieving better integration.

A comprehensive literature review was conducted to ascertain the challenges faced by the integrated design team (IDT) in the absence of the facilities managers’ review of design solutions, and underscore the significance of the early involvement of facilities managers during the DDRS. A questionnaire survey was then developed for collecting data on eight aspects of the current practices of early FM involvement during the DDRS. The questionnaire survey was administered to the FM departments of 13 long established, public universities in Saudi Arabia. Ten responses were obtained and analyzed.

The findings suggest that the early involvement of the FM department enhances the operation and maintenance of facilities. This has been measured through reductions in the number of architectural, structural, electrical, plumbing, heating, ventilating and air conditioning defects.

Recommendations were provided to facilitate the process of integrating the practices of two influential stakeholders of building projects. These recommendations encompass the need for maintainability considerations at the early schematic stage, the necessity of direct contact between the two parties and the necessity of facility managers’ increased familiarity of the design stage activities, among other recommendations. In this way, the study promotes the awareness of the significance of integrating FM with the IDT at the DDRS.

This study contributes to the literature and practice by presenting a detailed analysis of the integration process between the FM department and the IDT. Furthermore, the outcomes of the integration between the parties were measured to assess the effectiveness of the collaboration and highlight the possible areas of improvement.

While ISO 9000 is undeniably the most prolific of all formal quality assurance (QA) standards, the experiences that the construction industry has had with it are at best mixed. Past research done to investigate its impact, in terms of benefits and costs, suggest that most construction firms have yet to achieve optimal results from its implementation and use. One possible explanation lies in the generic nature of the standards itself. This study investigates the impact of ISO 9000 on building defects. By focusing onto this very fundamental aspect of construction quality, it shows how ISO 9000 certification for contractors can affect the amount of defects occurring in their building projects. Augmented with findings from an in‐depth case study, a clearer understanding into the mechanisms of defects and its causes is derived. With that, a conceptual framework for effective defects reduction, based on the ISO 9001 model of QA, is developed.
