Abstract
Purpose
The continuous failure of construction projects notwithstanding appreciable increase in project management knowledge has necessitated a proactive approach of assessing early warning signs (EWS) of building projects failure. Building projects are expected to show warning signs before experiencing crises, comparable to a patient displaying symptoms of a disease. Thus, this study aims to examine the EWS that predisposed building projects to failure in Nigeria to provide empirical data for enhancing projects delivery.
Design/methodology/approach
Primary data were used for the study. Structured questionnaire was administered to consultants and contractors’ personnel within Lagos State, Nigeria. A total of 180 copies of questionnaire were administered and 134 copies (combined response rate of 74.44 per cent) were retrieved. Frequency distribution, percentages, mean item score and Mann–Whitney test were used to analyse the data.
Findings
Most construction professionals applied the EWS approach from project planning and early construction phase. The most significant EWS predisposing building projects to failure were “Management inability and incompetence to proactively detect and manage problems at early project stages”, “Actual expenditure is constantly shooting beyond cost estimates” and “Incurred costs already getting higher than the anticipated benefits”. Project/construction management-related symptoms are most significant to predisposing building projects to failure.
Practical implications
The study provided implications for effective project management of building projects through proactive approach which is very paramount to improving the delivery of building projects in Nigeria.
Originality/value
The study provides implications for proactive management of building projects, thereby enhancing the delivery of building projects.

Abstract
Purpose
The failure and abandonment of construction projects have proven to be insurmountable problems incessantly militating against the efficient performance of the construction industry in Nigeria. The complexity, technicality and a host of other project execution issues unique to multi-storey building projects do increase their susceptibility to failure and abandonment. Thus, the purpose of this paper is to examine the factors influencing failure and abandonment of multi-storey building projects in Nigeria. This is with a view to provide inferential empirical data that could enhance successful delivery of multi-storey building projects in Nigeria.
Design/methodology/approach
Primary data were used for the study. A structured questionnaire was administered on consultants and contractors’ personnel within Lagos State, Nigeria. A total of 180 copies of the questionnaire were administered ,and 134 copies which represent a combined response rate of 74.4 per cent were retrieved. The data were analysed using frequency distribution and percentages, Mean item score and factor analysis.
Findings
The factors most significant to the failure and abandonment of multi-storey building projects are inadequate funding by the client, improper planning at the pre-construction phase, structural failure in multi-storey building during construction, bankruptcy/business failure of the contractor, improper scheduling of the building project activities and failure to engage qualified professionals with technical expertise and experience. The rated factors clustered under human resources capability, planning and structural quality, contractor selection and variation, insecurity and variation, and force majeure and political risk.
Research limitations/implications
The study was limited to multi-storey building projects in Lagos State, Nigeria. Further studies could focus on specific resuscitation strategies for abandoned multi-storey building projects.
Practical implications
The study provided implications for effective project and contract management of multi-storey building projects which is very paramount to improve the delivery of complex, technical- and capital-intensive building projects in Nigeria.
Originality/value
The study provides specific implications for the management of multi-storey building projects, thereby enhancing the delivery of building projects.

Abstract
Purpose
The purpose of this paper is to focus on the ongoing discourse centred on enhancing building performance to provide an interpretation of life cycle cost (LCC) analysis, directly applicable to building construction in coastal areas located in tropical wet–humid settings.
Design/methodology/approach
A survey of 50 buildings based on physical observation is carried out to identify typical failure patterns in wet‒humid environment. Further, a comparative initial construction cost and LCC analysis is computed for two alternative building schemes with identical floor plans: Scheme A using sound construction and detailing to guard against future maintenance problems and Scheme B adopting the typical designs evident in the study area.
Findings
The result of the analysis shows that in the long-run scheme, A is an economically more viable option than B, as the increased initial costs are entirely offset by the reduced running cost.
Research limitations/implications
The contextual nature of LCC analysis poses difficulties in applying the evidence provided in this study to provide a generalisable financial justification to buildings clients.
Practical implications
The outcome of the study provides analytical validation to overcome resistances and enables informed decision making by clients, which is necessary to promote transition from conventional to environmentally responsive design choices suitable to wet–humid conditions.
Originality/value
The study provides an interpretation of LCC analysis, directly applicable to building construction in the tropical wet–humid setting of coastal areas against the backdrop of inconsistencies in the practical application of the theory of LCC.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
Whilst forming a meaningful contribution to stimulate debate, further investigation is required to tangibly establish integrated approaches to identify and obviate defects.
Practical implications
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.
Social implications
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.
Originality/value
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.

Abstract
Purpose
The study investigated the perceived causes of structural failure of public buildings, frequency of stability checks, stability checking procedures, measures to enhance public building stability checks and the roles of facility managers in the Accra Metropolis of Ghana.
Design/methodology/approach
Following a comprehensive literature review, the study employed a structured questionnaire survey and gathered the opinions of sixty-seven facility managers on the facility management practices. Following statistical pretesting of the dataset for reliability, distribution and agreement among the responses, the study analysed the dataset using mean scoring and weighted analysis.
Findings
The analysis showed that external building inspectors rarely inspect stability checks of the studied public buildings in Accra. It is also found that both reactive and proactive stability checking protocols are implemented in public buildings in Accra, but inadequate knowledge of facility managers limits technical stability checks. The study further revealed that stability checks of public buildings can be enhanced through incorporating site and location conditions into the design early upfront, active engagement of facility managers in the design and construction of public buildings, adequate budgetary provisioning for planned maintenance of public buildings, and encouraging appropriate use of public buildings.
Originality/value
This paper, to the best of the authors' knowledge, represents the first attempt to comprehensively examine the causes of structural failure of public buildings, frequency of stability checks, stability checking procedures, measures to enhance public building stability checks and the roles of facility managers in Ghana, from the perspective facility management.

Abstract
The extent of defects within the construction sector is considerable. This not only has implications for final built products, but also impacts on remedial and repair work, time delays and additional cost. This research work aims to evaluate the success of applying knowledge engineering (KE) techniques to the domain of defect prediction focusing specifically on brickwork mortar. A structured approach is developed which relates to the prediction of defects on housing developments. Knowledge engineering techniques are assessed to facilitate the provision of domain knowledge readily accessible by design engineers and architects. The KE techniques are used as an alternative to the current methods, techniques and technologies used within the construction industry. This is achieved by assessment of the predictive approach to facilitate decreases in ‘quality losses’, i.e. decreases in pre‐mature failure and hence improved quality performance. Attention is also given to the consideration of complex defects to promote increased efficiency in communication and co‐ordination of information for design and building processes, thereby helping to reduce the cost of maintenance and repair work.

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
Purpose
It has been found that the cost for housing maintenance is relatively high due to poor maintenance practices. This paper aims to determine and identify the factors contributing to rising maintenance costs.
Design/methodology/approach
A quantitative approach was adopted that sought to gather factual data using the approach taken by El‐Haram and Horner. The research first identified the critical factors through a literature review. A total of Eighty questionnaires were then distributed to relevant respondents such as building managers or supervisors, maintenance management staff and others. In total, 31 completed questionnaires formed a database for descriptive and ranking analysis.
Findings
The research concluded that five of the most dominant factors were expectation of tenants, building materials, building services, building age and failure to execute maintenance at the right time. Meanwhile, it was found that two of the most influential impacts were outstanding maintenance charges and over‐budget.
Originality/value
Measures to minimise the housing maintenance cost were obtained, such as participation of tenants and residents in housing management works and allows their acceptance of a lower standard expectation.

Abstract
Purpose
This paper aims to explore the state-building attempts in post conflict zones. The neoliberal economic system has dominated the key international organizations such that the latter have designed their approaches for state building based on it. The framework of these approaches focuses on minimal state interventions in the economy and free markets by being as a “one size fits all”. However, several prominent financial institutions such as the United Nations, World Bank and International Monetary Fund that have implemented some of these approaches in various regions resulted in limited success.
Design/methodology/approach
This paper is comparing two cases of state building before statehood and sovereignty, and this comparison comes in socioeconomic practices of international players and local governments.
Findings
This model has been carried out in Palestine and Kosovo but failed in meeting the expected demands of independence and prosperity. Instead, it resulted in more failures in the markets and caused a decline in the macro and micro economic indicators.
Originality/value
The key reasons for such failures, specifically in Palestine and Kosovo, are believed to be related to the top-down approach of policy-making, the lack of independence and sovereignty and the absence of popular and local participation in policies and plans. In such context, this approach has to be further revised to create a more inclusive participatory and representative model.

Abstract
The failure of a wall in a Welsh farmhouse in the middle 1960s was regarded as an isolated problem when it was discovered that the cause of the failure was corrosion on the cavity wall ties. This was the first failure of a wall tie that was reported to the Building Research Establishment. Within a few years of the Welsh report, other instances of this type of failure were being reported to the BRE. The subsequent investigation of the durability of wall ties revealed a failure in the galvanised surface to the metal of the ties. Similar ties were subjected to close examination by the BRE.
