Purpose Communication plays an important role in the quality of the relationship, trust and collaboration among construction project teams. Literature suggests that effective communication is vital for achieving improved project performance. The purpose of this paper is to identify and assess the barriers to effective communication in the Nigerian construction industry, using attribution theory paradigm. Design/methodology/approach Questionnaires detailing 15 barriers to effective communication were administered to consultants and contractors engaged in the Nigerian construction sector. In total, 100 valid responses were analysed using mean score, factor analysis and factor score. Findings Unclear project objectives, ineffective reporting systems and poor leadership were ranked as the most significant barriers to effective communication. Factor analysis uncovered that the principal reasons responsible for ineffective communication include: managerial and technical barriers and credibility and background barriers. Practical implications The results provide information on barriers which needs to be addressed in order to improve communication in construction projects in Nigeria. There is a need to conduct post-completion reviews of construction projects so that project team members can learn and share knowledge on past experiences. Although the present study was conducted in the Nigerian context, it is envisaged that the research outcome will be widely applicable to other developing countries. Originality/value The study provides insights on the perceived barriers to effective communication in Nigerian construction projects. The paper presents the direction for further research aimed at improving communication in construction projects in Nigeria.

Full textAbstract:
Purpose – Quality function deployment (QFD) is a method for structured product planning and development that enables a development team to specify clearly the wants and needs of customers. This method has been successfully employed in the construction industry in developed countries. However, the benefits of QFD have not been practically realised in developing countries such as Nigeria. Hence, this research aims to investigate the awareness and effectiveness of QFD as a quality control technique that enhances the satisfaction of clients in terms of quality, cost and project delivery time in design and build projects. Design/methodology/approach – A qualitative and quantitative research approach in the form of in-depth telephone interviews and questionnaires was used to obtain the views of construction professionals such as civil engineers, architects, project managers, chief executive officers and trades people involved in design and build projects in the Nigerian construction industry, as well as 50 clients to ascertain the level of satisfaction derived from these design and build projects. Findings – The results of this research are derived from statistical analysis and show that there is currently little awareness of QFD within the Nigerian construction industry or its potential effectiveness in design and build projects. Originality/value – There has been little previous research into the use of QFD in the Nigerian construction industry, hence this paper provides insight but also highlights the need for further research.

Full textAbstract:
Purpose This paper aims to evaluate Nigerian contractors’ perceptions regarding the effects of positive and negative cash flow during construction projects, with a view to establishing effective strategies for cash flow management. Design/methodology/approach A desktop-based literature review is used to develop a cross-sectional questionnaire survey which uses Likert items to elicit responses from construction professionals on: the reasons for cash flow problems; the impacts of negative and positive cash flow; and the potential solutions for improving cash flow on construction projects. Findings The study finds that delay in payments, difficulty in obtaining financial aid and inadequate budgetary control are the causes of cash flow problems during construction projects. Cumulatively, these issues result in project delays, reduced profit margins and in the worst scenarios, abandoned projects. Originality/value There has been limited research into the effects of positive and negative cash flows on construction projects in Nigeria and indeed, the wider geographical location of West Africa. This study addresses this observed dearth and consequently advances methods and solutions to deal with the problem of poor cash flow management in the Nigerian construction industry.

Full textAbstract:
<p>A change is an amendment or addition with respect to the original plans, specification or other contract documents and vital factor in construction project management. A change order is an instruction from an employer approving a change. Construction projects in Nigeria have suffered deleteriously as a consequence of extensive change orders, which has manifested in cost and time overruns, disputes, arbitration, litigation and even the abandonment of projects and this negatively impacts on the efficiency of the Nigerian construction industry.This paper explore the extent change order management strategies correlate with overall building project in Nigeria. Thirty strategies for managing change order were identified through intensive literature search. Twenty -one factors peculiar to the Nigerian construction industry were used to develop a questionnaire. A total of 323 questionnaires were administered through stratified random sampling to respondents in the cities of Abuja, Kano and Bauchi. The study targeted construction Consultants namely Architects, Quantity Surveyors Building Engineers, Service Engineer (Electrical &amp; Mechanical), Contractor and Building owners in three sub-study cities. The study recorded an overall response rate of 80.8 %. Using SPSS version 22, the questionnaire was subjected to reliability test. Statistical analysis was used using average index; spearman correlation coefficient; factor analysis and multiple regression were used to analysis data from survey questionnaire. The study reveal that change orders are better manage at the design stage and that clear and thorough project brief, better initial planning and thorough detailing of design are the three topmost management strategies. The study established that overall project success is impacted by change order management with a R<sup>2</sup> of 0.252, meaning that change order management at the design stage accounts for 25.2% of the variation in building project outcomes. The Spearman's (rho) also show strong agreement among respondents. The study concluded that proper adoption and use of project implementation phase principles by project sponsor, increased effort at the design stage of projects by project participant and allocation of adequate resources to project requirement will help minimize change orders in project delivery in Northern Nigeria.</p>

Full textAbstract:
Delays and disruptions are among the challenges faced in the course of executing construction projects in Nigeria. Delays as well as disruptions are sources of potential risks that current studies are looking into ways to manage such as technical, social, economic, legal, financial, resource, construction and commercial. The purpose of this research is to assess causes and effects of delays and disruptions in the Nigerian construction industry. This study is descriptive, designed to obtain views from clients, consulting firms, regulatory boards and construction firms in regard to causes and effects of delays in construction projects. Two sampling techniques were used to select respondents namely: purposive and random sampling. Literature review, questionnaires techniques were used to collect data for the study. Findings reveal that the main causes of delays and disruptions are: design changes, delays in payment to contractors, information delays, funding problems, poor project management, compensation issues and disagreement on the valuation of work done. On the other hand, time overrun, cost overrun, negative social impact, idling resources and disputes are the main effects of delays and disruptions. The study concludes that there still exist a number of causes of delays and disruptions and their effects put construction projects at great risk that have an effect on their performance. It is therefore recommended that adequate construction budget, timely issuing of information, finalization of design and project management skills should be the main focus of the parties in project procurement process.

Full textAbstract:
Purpose Abandonment of construction projects is still a burning issue in Nigeria. Beside the poor financing of educational infrastructure, abandonment of construction projects remains a significant contributor to the inadequacy of facilities in Nigerian public tertiary educational institutions. The purpose of this paper is, therefore, to assess the causes of abandoned projects specific to public institutions of tertiary education in Nigeria, with a view to providing empirical data that are generalizable to enhancing successful delivery of teaching and research facilities. Design/methodology/approach Primary data used for the study were obtained through questionnaires administered to 47 professionals comprising 8 architects, 12 mechanical and electrical engineers, 15 civil/structural engineers, 4 builders and 8 quantity surveyors who were involved in physical development of construction projects in public tertiary educational institutions in Osun State. The data were analyzed using mean analysis, factor analysis and the Kruskal-Wallis (K-W) test. Findings The factors most significant to abandonment of tertiary educational institutional projects were delayed payments, fund mismanagement, inadequate budgetary allocation, inadequacy of finance, inflation and bankruptcy of the contractor. Findings also showed that not all factors causing abandonment were significant to tertiary institutional projects. The significant factors clustered under stakeholders’ response capacity, poor financial management, inadequate planning and monitoring, and unexpected occurrences. The K-W test showed significant differences among the categories of tertiary institutions on the ranking of the most significant causes of abandoned projects. Research limitations/implications The study was limited to public tertiary educational institutions in Osun State. Further studies could focus on public health institution projects and private tertiary educational projects to improve the body of knowledge on the subject of causative factors for project abandonment. Practical implications The study provided implications for effective contract management of public tertiary educational institutional projects, which is a significant step to improving the available teaching and research facilities in Nigerian tertiary institutions. Originality/value The study provides implications for effective contract management systems of projects for public tertiary educational institutions, thereby improving the available teaching and research facilities.

Full textAbstract:
Default by contractors in meeting the time and cost performance of a project is usually counterproductive. Considering safety from the high financial burden of construction projects, clients are compelled to seek a level of guarantee in bonds to safeguard them from financial problems and provide incentive for proper and timely completion of the project by the contractor, thereby minimising failures and risks. Therefore, the study assessed the level of bond utilization in Nigerian construction industry, with a view to examining the benefits of its utilisation in construction projects. Survey method was adopted in which questionnaires were used to collect data from respondents. With a response rate of 45.30% (164 of 362), the collected data were analysed using descriptive and analytical scientific method. It was found that the level of bond utilisation in construction contract is high, with performance bond and Advance payment bond being most commonly used construction bond types. Assurance of performance and financial security are the major benefits of bond utilisation. The study recommends that there is need for more enlightenment of construction participants on the various types bond used in construction contracts

Full textAbstract:
This study provides a holistic assessment of the current waste management strategies implemented in Nigerian construction projects. The data used in this study were collected from both primary and secondary sources. The primary data were collected through survey questionnaires distributed via emails of the targeted respondents who are construction professionals in the study area of Lagos metropolis, while the secondary data were collected via the review of related literature. Out of the 200 questionnaires distributed, only 168 valid forms were retrieved. The collected data accounted for 84% of the entire survey and were suitable for the analysis. An exploratory factor analysis was conducted while the reliability of the research survey instrument was tested using Cronbach’s alpha coefficient reliability. The result indicated that the waste management strategies were clustered into three groups, comprising practical legal framework and modular construction, sustainable procurement and material optimisation, and proper construction detailing and design. In conclusion, the waste management strategies implemented in Nigeria were assessed as being “not sustainable enough”. However, it is recommended that there is an upgrading in either the approach or method of application of waste management strategies in order to ensure its sustainability.

Full textAbstract:
Purpose – With the increase in the cases of construction claims in Nigeria, many projects have remained uncompleted, while many of those completed receive poor client satisfaction. The purpose of this paper is to investigate how construction claims are managed. Design/methodology/approach – In total, 58 claim factors were identified and addressed to construction professionals through survey to indicate the extent at which the factors contributed to claims. A case study was conducted to illustrate claim management. Findings – In total, 37 factors were the major source of claims. Late payment, delayed approval of change order and delay cost were the extremely influential while the least were storage charges, loss of productivity, and costs of preparing claims. Evidences revealed that all stakeholders should play active roles to deliver “claim free” projects. Practical implications – The findings will be useful to practitioners in the effort to improve project delivery by providing some guidance on claim minimization. It is hoped that this study will encourage academics to conduct more research on this issue. Originality/value – There is no known conclusive empirical study on construction claim factors in Nigeria. In light of this, the findings offer greater opportunities for claim minimization/avoidance.

Full textAbstract:
In Nigeria, 50% to 70% of construction projects are delayed due to unexpected events that are linked to lapses in performance, near misses, and surprises. While researchers have theorized on the impact of mindfulness and information systems management (ISM) on unexpected events, information is lacking on how project teams can combine ISM and mindfulness in response to unexpected events in construction projects. The purpose of this case study was to examine how project teams can combine mindfulness with ISM in response to unexpected events during the execution phase of Nigerian construction projects. The framework of High Reliability Theory revealed that unexpected events could be minimized by mindfulness defined by 5 cognitive processes: preoccupation with failure, reluctance to simplify, sensitivity to operations, commitment to resilience, and deference to expertise. In-depth semi-structured interviews elicited the views of 24 project experts on team behaviors, tactics, and processes for combining mindfulness with ISM. Data analysis was conducted by open coding to identify and reduce data into themes, and axial coding was used to identify and isolate categories. Findings were that project teams could combine mindfulness with ISM in response to unexpected events by integrating effective risk, team, and communication management with appropriate training and technology infrastructure. If policymakers, project clients, and practitioners adopt practices suggested in this study, the implications for social change are that project management practices, organizational learning, and the performance of construction projects may improve, construction wastes may be reduced, and taxpayers may derive optimum benefits from public funds committed to construction projects.

Published Article<br>Construction projects all over the world involve many challenges, particularly for large public projects. The emerging complex nature of construction activities has brought with it characteristic features, such as, cost increases, delay in the delivery of project, to which rework (carrying out an activity more than one time) has a high contributing factor, stemming from imperfection. This study identified the sources of rework on construction projects in Nigeria from three perspectives: the client, contractor, and consultant. The study was concentrated on the South West part of Nigeria. The quantitative research method was adopted. Random sampling technique was employed in the selection of sample size. A total of one hundred and twenty (120) questionnaires were analysed using inferential statistics.
The following are the findings of this study: the contributions of the client leading to rework are in the form of poor communication, inadequate construction planning and poor management practices. From the consultant, they are: lack of understanding and correct interpretation of customer requirements, constraints in carrying out activities and inexperience of personnel and on the part of the contractor they are: wrongly laying of forming course, poor quality concrete, and poor plastering. Based on the conclusions reached, the following recommendations were drawn. They are: the development of a standard information gathering format relative to clients 'by designers and clients' writing down their intentions before visiting designers; formal technical training should be given to foremen on permanent appointments with organisations, attention should be given for adequate supervision, and construction methods should be analysed before selection and their use.

Full textAbstract:
Satisfaction has consistently been a source of concern to clients, stakeholders and customers in the construction industry globally. In Nigeria, despite the huge financial investments in construction and its associated economic benefits, construction projects are characterized by poor quality in aesthetics, high costs in maintenance and failure to meet or exceed the customers’ quality expectations. An even greater challenge is faced when considering government construction projects as re- occurring issues like on time delivery, operational and aesthetic excellence and even project abandonment continue to resurface. Although previous studies have developed models and frameworks to improve customer satisfaction in product and service organisations, researchers have not treated in detail issues involving customer satisfaction within projects which do not have profits and financial gains as the driving force such as government construction projects. The aim of this research was to develop a framework that would identify particular areas associated with project quality where adequate resources could be channelled in order to enhance customer satisfaction in government road construction projects in Rivers State, Nigeria. Sequel to an extensive literature review, a conceptual framework was developed to establish the relationship between three attributes of project quality namely performance, reliability and aesthetics and two attributes of customer satisfaction measured through contractor re-patronage and referral. 503 road construction practitioners within the Port Harcourt metropolis of Rivers State, Nigeria participated in a quantitative survey and data obtained was subjected to stepwise multiple regression analysis. The results showed that a strong, positive and significant relationship existed between the attributes of project quality and customer satisfaction with project quality explaining 54.8% of the variance in contractor re-patronage and 61.8% of the variance in contractor referral. Performance was however found to have the greatest effect on contractor re-patronage (R2=.550, adjusted R2=.548) while aesthetics had the highest effect on contractor referral (R2=.572, adjusted R2= .571). Reliability was found to have the weakest effect on customer satisfaction and could be attributed to its civil and structural Engineering links which are either unknown or invisible to the customer. 10 structured interviews with construction professionals were used to validate the developed framework and justify the research design. The findings support the framework and suggest that the knowledge and analysis of the construction costs, the use of competent professional experts, the provision of a revised legal framework for road construction, delegation of responsibility for road maintenance, avoidance of project abandonment, identifying and mitigating construction risks, adopting a strategy for project monitoring, enforcing health and safety considerations, provision of innovative excitement factors as well as post project evaluations were essential for enhancing project quality and customer satisfaction from government road construction projects. The study advocates for an adoption of the framework and concludes by making recommendations including the incorporation of government and private construction practitioners and further identifies areas for future study.

Project managers in the Nigerian real estate construction sector are facing challenges in delivering real estate projects profitably. The purpose of this correlational study was to examine how comprehension, motivation, skills, resources, and communication can predict project success in the real estate construction sector in Nigeria. Understanding these elements was necessary for developing project management strategies aimed at optimizing profitability. The population of the study was project management practitioners in the Nigerian real estate construction sector who are facing challenges in delivering real estate construction projects profitably. The duck alignment theory served as the theoretical framework for the study. Data collection was through a survey instrument questionnaire called the Project Implementation Profile. Multiple linear regression analysis confirmed a significant relationship between each of the 5 independent variables and the dependent variable, F(5, 70) = 216.704, p = .000, R2 = .939 upholding all the alternative hypotheses. The regression model results showed that each independent variable is a significant predictor of the dependent variable, project success at p < 0.05 and C.I. = 95% criteria. Project managers may use the findings of this study to increase the profitability of the real estate construction sector, which would translate to a business expansion resulting in an increased production of houses and housing services. The implications for positive social change may include the generation of employment for skilled and unskilled workers and the multiplier effects, which support the stimulation of sustainable economic activities in the developing economy of Nigeria.

Development is a difficult, painful and long-term enterprise. Not only because of world wide social and economic changes with extensive debts problems, inflation, recession and slow growth, but it is also a matter of finding the technically and economically optimum solution. Over the long-term, the challenge for developing countries is to use their limited resources more efficiently and more equitably through the management of all investment outlays in both the public and private sector. Construction is a major investment sector in Nigeria, attracting an average of over 60% of all capital investment, with over 70% of that 60% sponsored by the public sector. Construction projects handled by the public sector in developing countries are however fraught with problems, from inception through to completion and beyond. This is well known to members of the public sector agencies. Year after year, in good times and bad, development projects suffer from a host of problems: some of design; others of appraisal; and still others of implementation. Most construction projects are characterised by overruns in cost and time, and are sometimes halted altogether before completion. It is therefore necessary to understand the problems underlying the system being practised, to establish a realistic pattern, and to be able to interpret and correct any abnormalities. A lack of understanding of the constraints leads to unrealistic planning, and to later problems that may become insoluble. This research was therefore aimed at identifying these problems, many of which arise from attempts to implement a technology, in this case management technology, in a country other than the country of its origin. In a comparative study between Nigeria and Scotland a large number of public agencies which sponsor construction projects, and the contracting and consulting organisations that work for these agencies, were surveyed using both face-to-face interviews and the postal questionnaire technique. It was found that the major problems in Nigeria are: bureaucratic obstacles affecting timely payment to contractors; ambiguity in consultant/client contract agreements; lack of sufficient qualified professionals in the agencies; and lack of suitable information on which to base initial estimates. Recommendations for improving practice in Nigeria include: administrative reform of construction agencies to reduce the trammels of bureaucracy; a better system of funding by central Government; establishment of a construction cost information agency; and payment of competitive salaries to public sector professional staff. These changes, taking into account the cultural environment of Nigeria, should enable decisions to be made with greater certainty of outcome by all parties involved.

Full textAbstract:
Construction Projects are notorious for demonstrating poor performance and under achievement as usually indicated by project objectives. Project managers in the construction industry are faced with many research suggestions in literatures to improve performance but there are confusion in the implementation of these recommendations. These could be attributed to dearth of literatures that comprehensively treat critical success factors; CSFs as drivers of key performance indicators; KPIs for assessing construction project performance. KPIs are measure of indication of the workings of CSFs for project performance thus, both are present on projects and useful in exploring the underlying dynamic structure of complexity inherent in construction projects. The study determine CSFs for KPIs of cost, time, quality and health/safety which were used to develop a dynamic Project Performance Diagnostic Model which gives feedback for improved decision making in the context of diagnosing project performance in the Nigeria construction industry. This research tends not to discard the positivism or interpretivism philosophical stance by being pragmatic. Pragmatism argues that the most important determinant of epistemology, ontology and axiology adopted on research is determined by appropriately answering particular research question thus, this research adopted the pragmatism philosophy. The research process involves different phases with quantitative-qualitative research technique corresponding to the two respective ends of the positivist-constructivist paradigm continuum. The data for this research were collected through interviews of focus expert group and survey questionnaire in a form of data generation triangulation. Results of the qualitative aspect were used to develop a questionnaire, which was analysed using statistical techniques including factor analyses. The CSFs of KPIs so analysed were used to develop PPDM system dynamic based model to simulate the interplay and effects of different CSF components for aiding decision making of project managers. The research suggests that Cost as a key performance indicator has the most overriding impact on construction project performance with three components. The three dimensions to Cost performance indicator are Contractor’s Management Capacity, Client’s Commitment to Progress of Project, and Economic Environment of Project Estimate. Time performance indicator would impact performance in four different dimensions identified as Design Team Commitment to Project Management Outcomes, Capacity of Contractor for Project Management, Construction Resource Management, and External Factors. Quality performance indicator discovered three-component dimensions labelled Project Communication Management with Design and Workforce, Contractor Capacity for Resource Management on Quality Objective, and Project Manager’s Competence on Information Coordination and Construction Method. There are two dimensions that impact Health and Safety performance indicator which are Effective Finance of Site Management for Health Safety Implementation and Capacity of Contractor for Project Management and Safety Programme. These different components of KPIs were used for the development of a dynamic Project Performance Diagnostic Model. The study emphasized the importance of contractor to cost performance and the design team commitment to time performance with the underlying relationship of the CSFs in predicting the KPIs.

Published Article<br>Hardly could projects be executed in Nigeria without alteration of design. This cannot be dissociated from designs which are not practically buildable or arising from changing taste of client. A study on factors influencing the buildability of designs in Nigerian construction industry was carried out to determine these factors and develop strategy to mitigate them. A total of one hundred (100) questionnaires were administered by the means of convenience and eighty six (86) was retrieved from a target population comprising; Architects, Builders, Engineers and Quantity Surveyors. The central tendency statistical tool was used for the analysis of data. The result of data analysis indicated that, clients briefing is an important factor for buildability of design. Among the influencing factors on buildability, complexity of the project followed by professional knowledge about construction ranks first and second and lastly cost economic value with no influence. On the current practice of buildability in Nigeria, the study revealed that Architects are mainly involved at the briefing stage to the award stages. While at the construction stage the Builder/Constructor features prominently at the various phases of construction. The study recommended the integration of Builder/Constructor at the early stage of building design.

Full textAbstract:
Innovative technologies for construction project management are constantly emerging in the construction industry's global landscape, yet the rate of failed projects within the Nigerian construction sector due to poor coordination of construction tasks is on the rise. An unanswered question in the literature remains as to why construction project managers in Nigeria remain slow to adopt new technologies for improving decision-making processes and project success rates. The purpose of this qualitative single case study with embedded units was to understand the perceptions of construction project managers in Nigeria regarding their barriers to technology adoption. This study was framed by 2 conceptual models: Usman and Said's model of factors contributing to information and communication technology adoption in Nigerian construction firms and Waziri, Mustapha, and Idris' model of factors influencing IT adoption in Nigerian construction organizations. Semistructured interviews involving 10 participants, reflective field notes, and archival data provided information regarding the barriers to technology adoption experience of construction project managers in Nigeria. Thematic analysis of the textual data and synthesis produced 5 conceptual categories for 14 identifiable themes from the study. The conceptual categories were (a) adoption of technology, (b) culture, (c) organizational performance, (d) innovative technology, and (e) interorganizational collaborations. The findings from this study may serve as a catalyst for positive social change by challenging existing technology-avoidance behavior in the Nigerian construction industry, and opening new opportunities for improved project delivery in the Nigerian national economy.

Full textAbstract:
The current shortage of artisans in the Nigerian house construction sector has constrained the productivity of the sector and exacerbated the nation‟s housing problem. The persistent neglect of the artisan training system has negatively impacted on the stock of artisans available for house construction projects. Nigeria‟s large and fast-growing population of over 140 million with an estimated growth rate of 3.2 percent has engendered increased investment in shelter provision; especially by individuals and families due to fast rising housing rentals- mainly in the urban centres. Past policies have not adequately addressed the realities of the skills crisis occasioned by inadequate and neglected apprenticeship training and poorly developed vocational education and training systems. The fallout of this is manifested in the difficulties faced by developers in sourcing suitably qualified and experienced artisans for house construction projects. In response to this challenge, an upsurge of migrant artisans and craftsmen from neighbouring West African nations like Togo, Benin Republic and Ghana to Nigeria has occurred in the recent times. They were attracted by building contracting firms to fill the gap created by inadequate artisan supply that is currently being experienced locally. This development is totally unacceptable as it exacerbates the overarching socio-economic problems in Nigeria, especially the already high unemployment rate which is estimated to be 23.9 percent. This study has consequently investigated the inadequate training of house construction artisans in South Western Nigeria; evolving interventions and developing a strategic model for improving the artisan training system to ensure an adequate and sustainable artisan supply in the house construction sector. The model incorporates best practices, rethinking strategies and integrated approaches in mitigating the identified challenges. The model is underpinned by reviewed literature and empirical findings. Quantitative surveys and interviews were utilised as the data sources. The research findings show that the factors which negatively impact on the artisan training system in the house construction sector include: the poor image of artisans in society; lack of recruitment strategies for attracting potential artisans; inadequate policy framework for training and employment; a faulty and rigid National Qualification Framework (NQF); the non-participation of employers in training; a poor funding mechanism; a weak regulatory framework and corrupt practices in training administration. Recommendations for addressing the inadequate training of artisans include education policy reforms to give priority to vocational education; a new regime of funding for vocational education and training; a review of the National Qualification Framework to integrate the vocational colleges with the university system; a reform of the regulatory framework; public re-orientation on the societal image of the artisans; adoption of a new approach of public- private partnership in artisan training; the provision of incentives schemes to attract potential artisans and the appropriation of the proposed model for an integrated approach to addressing the challenges.

Full textAbstract:
Project risk assessment is an effective tool for planning and controlling cost, time and achieving the technical performance of a building construction project. Construction projects often face a lot of uncertainties, which places building construction projects at the risk of cost, time overruns as well as poor quality delivery. Considering the limited resources of developing countries, there is need to complete building projects on-time, on-budget, and to meet optimal quality hence, risk management is an important part of the decision making process in construction industry as it determines the success or failure of construction projects. In line with this need, this research aims to establish a system to improve the time, cost and quality performance of building construction projects in developing countries, through a comprehensive risk management model that ensures the expectations of clients are met. To achieve the aim of this research, a mixed methodological approach was adopted. Through the review of literature, a conceptual risk management framework suitable to elaborate risk assessment of building construction projects especially for developing countries was developed. A questionnaire survey using a nonprobability sampling technique was conducted to elicit information from construction professionals in Nigeria to assess their perception of 79 risk factors identified from literature review based on the likelihood of occurrence and impact on projects using a five point scale. Responses from 343 construction professionals were drawn from 305 contractors and subcontractors and 38 clients (private and public) within the Nigerian construction sector. Response data was subjected to descriptive statistics to depict the frequency distribution and central tendency of responses. Subsequently, the risk acceptability matrix (RAM) was adopted to categorise and prioritise risk factors. 27 critical risks that affect building construction projects were identified. A Bayesian Belief Network (BBN) model was developed by structural learning and used to examine the cause and effect relationship amongst the 27 critical risk factors. The developed BBN model was subjected to validation using a multiple case study of two building construction projects in Nigeria. The result showed the interrelation between the 27 risk factors and how they contributed to cost and time overruns as well as quality problems. The critical risks directly affecting the cost of building construction project were: fluctuation of material prices; health and safety issues; bribery and corruption; material wastage; poor site management and supervision; and time overruns. The critical factors identified to directly affect quality were: supply of defective materials; working under harsh conditions; improper construction methods; lack of protective equipment; ineffective time allocation; poor communication between involved stakeholders; and unsuitable leadership style. Time overruns on building construction projects was directly caused by: quality problems; low productivity; improper construction methods; poor communication between involved parties; delayed payments in contracts; and poor site management and supervision. As a consolidation of the findings of this research, a BBN model for identifying risk factors that directly affect time, cost and quality on building construction projects has been developed which has the potential for assisting construction stake holders to manage risks on their projects. In view of the findings, a best practice system for risk management in building construction projects in Nigeria has been developed with an implementation guide to help building construction practitioners to successfully implement risk management on their building construction projects. Suitable risk responses, also in the form of recommendations have been identified. The strategies include actions to be taken to respond to risks based on their perceived significance or acceptability as well as some positive risk responses, such as exploiting, sharing, enhancing and accepting, and other negative risk responses, such as avoidance, mitigation transfer and acceptance.

Full textAbstract:
The construction industry in Nigeria has continuously witnessed rapid development as a result of massive investments in infrastructural projects such as housing. The continuous growth of this industry and the conventional approach to construction practices in Nigeria have negatively affected the environment and the wellbeing of the populace. Therefore, the concept of green architecture, also known as sustainable architecture, is a new approach in Nigeria’s construction industry that strives to achieve environmental sustainability. However, various factors have hindered its adoption and utilisation. This study, therefore, examined the various factors hindering the use of green architecture through various literature reviewed and administered questionnaires to built environment professionals in Nigeria to ascertain their perception of those identified factors. Data gathered from the questionnaires were analysed using descriptive statistical tools and ranked according to each factor’s mean index score and relative importance index. The results of the study revealed the most prominent factors hindering the utilisation of green architecture in Nigeria. Hence, findings from this study suggest that more efforts such as public enlightenment and the provisions of incentives are needed to be done by the government, built environment professionals, and other stakeholders in Nigeria’s construction industry for the promotion of green architecture.

Full textAbstract:
Existing approaches to risk management in construction procurement primarily dwell on strategies designed for commonly identifiable risk factors in typical project environments. Commonly identifiable risk factors would include too early or late material delivery - a condition typically ameliorated by implementing a Just In Time (JIT) plan; inferior construction materials typically mitigated by employing trusted vendors; or ineffective contractors primarily avoided by the use of experienced contractors. The purpose of this paper is to present a coherent model for procurement risk management for construction and infrastructure development projects within the context of dynamic project environments - complex, or chaotic. For the purpose of this study, a critical risk path activity is one in which a delay of activity completion not only leads to project delay, but does so in a manner that may be fatal to project or at best, far greater than the actual delay. The study incorporates observations and theory with practical application for improving initiatives by emergency infrastructure development response organizations such as FEMA (Federal Emergency Management Agency) and USACE (US Army Corps of Engineers) in the United States, the NEMA (National Emergency Management Agency) in Nigeria, or ANDMA (Afghanistan National Disaster Management Authority) etc. This study presents risk response plans aimed at improving the potential occurrence of positive risk aspects while reducing, or eliminating the same for negative risk occurrences. This study explored material, equipment, and skilled labor procurement strategies related to project risk management from the perspectives of scheduling, cost, and quality - three factors often referred to as the triple project constraints. It identified gaps within specific national and multinational organizations' approaches, and provided detailed recommendations for process improvements from the procurement management perspective to ensure the potential for successful project outcomes in unstable project conditions.

Full textAbstract:
The continuous rise in population, urbanization and expansion of cities has triggered a corresponding increase in construction and demolition activity. The frequent collapse of buildings attributed to poor structural design, building decay, and/or use of substandard materials has generated a substantial increase in construction refuse, also referred to as Construction and Demolition (C&D) Waste. This waste stream originates from residential, commercial, agricultural, institutional and industrial building projects for new builds, reconstruction, expansion, and refurbishments/rehabilitation. Most studies in Nigeria have generally focused on solid waste management without considering the uniqueness of C&D and giving it the attention needed, in order to achieve sustainable urban spaces that are highly functional, safe, convenient, and livable. This study seeks to investigate the different approaches and processes of C&D waste management in the City of Jos, in the Plateau State of Nigeria. The mix method was adopted for this research whereby quantitative and qualitative data was collected through a structured questionnaire for construction enterprises, as well as face-to-face interviews with the agencies responsible for waste management in the city. A total of 21 construction companies (representing about 10%) were randomly selected for questionnaire administration while interviews were conducted with the Plateau Environmental Protection and Sanitation Agency (PEPSA) and the Jos Metropolitan Development Board (JMDB) who are responsible for waste management. Investigations revealed that C&D waste consists of heavy and non-degradable materials such as: sheet metal roofing, sand, gravel, concrete, masonry, metal, and wood to mention only a few. The construction companies are solely responsible for: the collection, storage, transportation and disposal of wastes generated from their activities. Approximately 60-70% of the C&D waste materials are either reused, recycled or resold, while the remaining residual waste is indiscriminately disposed. Although the PEPSA and JMDB are responsible for waste management, their focus has been on establishing solid non-hazardous waste infrastructure systems, policies and plans. The absence of records of the quantity of C&D waste generated, the lack of financial data, and the omission of policies and plans for the C&D waste stream has resulted in a missed opportunity for a comprehensive and sustainable waste management strategy for the City and the state. To protect public health, valuable resources, and natural ecosystems, it is recommended that the C&D waste stream be included as part of the state’s waste management program, in consideration of the growing construction and demolition activity, by including C&D policies and guidelines.
