Abstract

Purpose

Sustainable construction practices are strongly correlated with a profitable and competitive construction industry, improved client satisfaction and efficient use of resources. However, due consideration is not being given to sustainable construction practices in Nigeria. Therefore, this study aims to identify the unsustainable construction practices on construction sites, the barriers to sustainable construction and possible strategies to improve sustainable construction in Nigeria.

Design/methodology/approach

A questionnaire survey of 50 construction sites was conducted with construction professionals on the sites as the specific target, out of which only 43 construction sites have at least a construction professional present at the site. Forty-three filled questionnaires from the respondents were used for descriptive (mean score, standard deviation and charts) and inferential analysis (t-test and Kruskal–Wallis) in this study.

Findings

The study shows that a large percentage (75%) of construction professionals in Nigeria are aware of sustainable construction. The descriptive and inferential analysis showed a disparity in the ranking of the 12 unsustainable practices, 14 barriers and 11 strategies among the respondents. Five unsustainable practices (“negative externalities”, “excess energy”, “unsustainable technologies”, “non-management of health and safety of workers” and “material waste”), six barriers to sustainable construction (“absence of historical data and exemplary projects on which construction professionals can build and learn from”, “lack of professional to handle the task”, “poverty and low urban investment”, “lack of urban and construction policy”, “lack of awareness” and “lack of technical know-how”) and three strategies to improve sustainable construction practices in Nigeria (“cooperation, partnership and participation”, “protection of biodiversity and conservation of natural resources” and “sustainability assessment system”) were found to be significant.

Practical implications

The study offers significant insights into the construction industry unsustainable practices, barriers to sustainable construction, as well as strategies for improving sustainable construction practices. These insights can be applied to other developing countries with an emphasis on geographical differences.

Originality/value

To the best of the authors’ knowledge, this is one of the recent studies in Nigeria that explored the context of sustainable construction in the construction industry by providing insights into the unsustainable construction practices, barriers and strategies to improve sustainable construction in Nigeria.

Abstract

Purpose

The purpose of this paper is to investigate the applicability of cloud computing (CC) and the challenges that contribute to more successful projects with a major sustainable construction development.

Design/methodology/approach

The previous studies provided information on CC implementation barriers, which were then evaluated by 104 construction stakeholders through a questionnaire survey. As a result, the exploratory factor analysis (EFA) approach was used to investigate these barriers. Furthermore, a partial least square structural equation model was used to build a model of these barriers (PLS-SEM).

Findings

The EFA results revealed that the above-noted factors are in a close relation with three key components, i.e. social, economic and communication. In addition, the proposed model results found the social barrier a key challenge to the implementation of CC.

Research limitations/implications

The results from this study can help decision-makers to improve the approaches regarding data fragmentation that has great effects on the execution of all construction projects. The focus of the paper is to enhance the data fragmentation processes. In addition, the results would be useful to strengthen the sustainability of existing construction projects by enhancing the implementation of CC.

Originality/value

The novelty of this research work will provide a solid foundation for critically assessing and appreciating the different barriers affecting the adoption of CC.

The purpose of this paper is to assess the cloud computing (CC) methods and tools towards the achievement of construction project sustainability in Nigeria.

Abstract

Purpose

The purpose of this paper is to assess the cloud computing (CC) methods and tools towards the achievement of construction project sustainability in Nigeria.

Design/methodology/approach

Data were obtained from the literature, complemented by a quantitative method using a questionnaire distributed among 104 respondents comprising mainly construction professionals in Nigeria. Subsequently, data were analysed using the exploratory factor analysis (EFA) method. In addition, the partial least square structural modelling was used to generate a model for the adoption of CC tools for sustainable construction.

Findings

EFA results indicated that the CC implementation tools could be categorised into four significant constructs: platform, communication, software and data storage. Results obtained from the model showed that platform tools were the most crucial tools for implementing CC in the construction industry.

Practical implications

The findings from this study are essential to the pursuit of perception of methods and tools connected to the vagueness of CC for future employees. In addition, the identified CC tools are expected to enhance the success of construction projects.

Originality/value

The novelty of this research work will be a benchmark or board for decision-makers to quality by adopting CC methods and tools in Nigeria’s construction projects to achieve their sustainable projects.

Abstract

Purpose

The paper aims to determine the possible drivers of value management (VM) in the construction industry with a view of providing better-quality construction and achieving value for money through its usage.

Design/methodology/approach

The study adopts a survey design, and construction professionals from various strata in the six geopolitical zones in Nigeria are assessed using a convenience sample through the use of a structured questionnaire. Frequency, percentage, mean score and one-sample t-test are used for analysing the data gathered.

Findings

Result revealed that although knowledge regarding VM practices is high, its adoption in the industry is average and the involvement of construction professionals in VM workshops is low. Government involvement through the introduction of VM policy, client commitment and proper understanding of VM methodology aid the adoption of VM practices.

Practical implications

This research was conducted across six geopolitical zones of the country as against common practice of selecting a particular region or state to represent the entire country. The findings therefore show a true reflection of the VM drivers in the country. Its recommendations can, to a large extent, increase the use of VM in the country and also other developing countries where construction projects are executed through a similar method, style and approach.

Originality/value

This paper highlights the possible ways of increasing the use of VM in the construction industry with a view to achieve better-quality construction and value for money.

The purpose of this paper is to examine the relationship between overcoming the value management (VM) implementation barriers and VM implementation in the Egyptian building sector.

Abstract

Purpose

The purpose of this paper is to examine the relationship between overcoming the value management (VM) implementation barriers and VM implementation in the Egyptian building sector.

Design/methodology/approach

A critical review of the literature on VM was used to through bibliometric analysis has been conducted to highlight the studies’ gap and establish the VM barriers. These obstacles were then contextually transformed via a semi-structured interview and a pilot study, and subsequently organized in the form of a theoretical model. The primary data was collected from 335 building stakeholders in Egypt through the administration of questionnaire surveys. Consequently, structural equation models of partial least squares were applied to statistically assess the final model of VM barriers.

Findings

The bibliometric analysis shows that there is an inadequate study on VM implementation barriers in the Egyptian construction industry and insufficient studies on implementing VM in developing countries. Results obtained from the proposed model showed that overcoming the VM barriers has a major connection with successful VM implementation. This is indicated with the value of ß = 0.743, which is necessary when the firm is overcoming 1 unit of VM barriers.

Originality/value

This study fills the knowledge gap by identifying and emphasizing the critical obstacles to VM implementation.

Abstract

Purpose

Cloud computing is one of the digitalization principles used in some sectors like banking, health and construction industry. This paper aims to examine the benefits of applying cloud computing for construction sustainability in Nigeria.

Design/methodology/approach

The cloud computing benefits-related data were retrieved from previous studies and complemented with a questionnaire survey to obtain data from stakeholders involved in the execution of construction projects in Lagos State, Nigeria, through a convenient sampling technique. In addition, the relative importance index (RII) technique was used to investigate the acquired data. At the same time, analysis was accomplished using exploratory factor analysis (EFA). Findings indicated that numerous benefits could be derived by adopting cloud computing in the Nigerian construction industry.

Findings

The findings from RII analysis showed the significant benefits of data storage ubiquity (i.e. location independence), high situational awareness, team collaboration, compatibility with advanced production facilities and improved project planning. Furthermore, the analysis of these benefits was conducted using EFA for the four construction maxims: construction productivity, back-office activities, design management and billing.

Originality/value

This research illustrated the benefits of cloud computing in achieving a successful construction project. Besides, these findings are not only useful for achieving sustainable construction in Nigeria but also applicable to many developing countries.

Abstract

Purpose

The ability of construction contractors to engage in construction bond agreement with guarantors depends on capital, experience, capacity and continuity. Using these criteria, the purpose of this paper is to provide insights into the bonding capacity of Nigerian contractors.

Design/methodology/approach

Factors required for bonding were examined based on a set of questions addressed to managers of contracting firms and personnel involved in issuing bonds and guarantees in commercial banks and insurance companies. The scorecard approach was employed to determine the bonding capability of the contractors.

Findings

Contractors’ financial strength and past performance on previous projects are the two important factors considered by guarantors in granting bond to contractors. However, the condition surrounding the bond, the legal capacity of the guarantor to issue bond and the identity of the guarantor are mostly considered by contractors in approaching a potential guarantor. Using the scorecard approach, about one-third of contractors have the necessary requirements to engage in construction bond agreement with guarantors. This ability of contractors is affected by years of experience of the firm but not by their location nor years of experience of their manager.

Practical implications

It is necessary for contracting firms to increase their capital base through merging, borrowing, etc., and also engage experienced professionals and workers in the execution of construction projects, as this will eventually improve their bonding ability.

Social implications

The study is limited to construction contractors registered with Ondo and Lagos State Governments and guarantors that are banks and insurance companies in Nigeria.

Originality/value

The paper specified various areas of concerns for Nigerian contracting firms in their bid to enhance their bonding ability. This will help them in overcoming various challenges and bottlenecks that may arise in securing bonds and guarantees from guarantors.

Abstract

Smart cities over the years is fast growing on people. Citizens and stakeholders that were defiant to its adoption are beginning to see the reasons for it. Due to one reason or the other, many of the stakeholders and the citizens were reluctant in seeing the vision in the smart city system. Some of these factors are expressed in the drivers and challenges faced in enhancing from a city to smart city. Along with these, measures and benefits that relate with smart city has helped in social and general awareness of what it represents and what stands to be gained if fully adopted. And this has helped in overall information available on smart city. The concluding part of the chapter gives a summary of the importance in addressing these drivers.

Abstract

People will continue to migrate from rural to urban areas. This always results in congestion in the civilised part where there is contention for the resources available. Policies have to be made and implemented in order to counter scarcity and redundancy as most urban cities tend to halt in growth when population is beyond controllable size. Smart cities come into the frame by alleviating the present condition of the places to that which is convenient for everybody. Quality of life, meanings of smart cities, quality of life of smart cities citizens are the priorities when implementing smart city concepts into sustainable development.
