Abstract

Purpose

This paper aims to present the result of a scientometric analysis conducted using studies on high-performance computing in computational modelling. This was done with a view to showcasing the need for high-performance computers (HPC) within the architecture, engineering and construction (AEC) industry in developing countries, particularly in Africa, where the use of HPC in developing computational models (CMs) for effective problem solving is still low.

Design/methodology/approach

An interpretivism philosophical stance was adopted for the study which informed a scientometric review of existing studies gathered from the Scopus database. Keywords such as high-performance computing, and computational modelling were used to extract papers from the database. Visualisation of Similarities viewer (VOSviewer) was used to prepare co-occurrence maps based on the bibliographic data gathered.

Findings

Findings revealed the scarcity of research emanating from Africa in this area of study. Furthermore, past studies had placed focus on high-performance computing in the development of computational modelling and theory, parallel computing and improved visualisation, large-scale application software, computer simulations and computational mathematical modelling. Future studies can also explore areas such as cloud computing, optimisation, high-level programming language, natural science computing, computer graphics equipment and Graphics Processing Units as they relate to the AEC industry.

Research limitations/implications

The study assessed a single database for the search of related studies.

Originality/value

The findings of this study serve as an excellent theoretical background for AEC researchers seeking to explore the use of HPC for CMs development in the quest for solving complex problems in the industry.

Abstract

Purpose

This paper aims to present the result of an assessment of the challenges of sustainable construction (SC) in two developing countries (Nigeria and South Africa). This was done with a view to improving sustainable project delivery, which is a problem among most developing countries.

Design/methodology/approach

The study adopted a quantitative survey approach with questionnaire used as the instrument for data collection from quantity surveyors, construction and project managers from both countries. Data analysis was done using a four-step analysis approach and relevant descriptive and inferential statistics were adopted.

Findings

The study revealed a considerable level of awareness of SC and involvement in the use of the same among the assessed professionals. Also, it was discovered that SC materials are mostly used in the aspect of surface finishing and masonry construction. Further findings revealed that resistance to change, client’s preference, fear of the increased cost of investment and inadequate knowledge and understanding of the concept of sustainability are some of the major challenges of SC in these countries.

Originality/value

The strength of this study lies in the assessment of happenings from two developing countries and its recommendation can to a large extent promote improved SC in developing countries particularly in Africa were construction activities are similar.

Abstract

Purpose

The economic downturn in Nigeria calls for the need to appraise the survival strategies being adopted by organisations within the built environment, as it plays a major role in the development of every nation. The purpose of this paper is, therefore, to appraise the survival strategies of organisations within the built environment, with a view to showcasing these strategies to ensure continuous survival of organisations within the industry.

Design/methodology/approach

The study adopted a survey approach, and construction professionals across the six geo-political zones of the country were sampled using structured questionnaire. Data gathered were analysed using percentage, Kruskal–Wallis H-test and factor analysis.

Findings

The study revealed that organisation- and workforce management-related strategies are the most adopted survival strategies in the country, as they have the highest factor loading and accounts for about 37 per cent of the total extracted factors. This is followed by the adoption of strategies relating to organisation’s innovation, diversification, financial management and organisation’s networking, the combination of which accounts for 27.5 per cent of all extracted factors.

Research limitations/implications

Findings of this study imply that although organisations within the built environment see the need for effective management of their organisation and workforce in a bid to survive in the harsh economic situation of the country, more need to be done as regards the other identified survival strategies, as they can help ensure the survival of these organisations.

Originality/value

This study contributes to the body of knowledge as it showcases the survival strategies being adopted by the different organisations within the built environment in the challenging Nigerian economy, as against the usual common practice of studying specific organisations within the industry.

Abstract

Purpose

This study presents a fuzzy synthetic evaluation of the challenges of smart city realisation in developing countries, using Nigeria as a case study. By defining and delineating the problems faced by the country, more viable directions to attaining smart city development can be achieved.

Design/methodology/approach

The study adopted a post-positivist philosophical stance with a deductive approach. A structured questionnaire was used to gather data from built environment professionals involved in the delivery of Nigerian public infrastructures. Six dimensions of the challenges of smart cities were identified from literature and explored. They are governance, economic, social, technological, environmental and legal issues. Data gathered were analysed using Cronbach alpha test for reliability, Shapiro-Wilks test for normality, Kruskal-Wallis H-test for consistency and fuzzy synthetic evaluation test for the synthetic evaluation of the challenges of smart city attainment.

Findings

The findings revealed that all six assessed dimensions have a significant impact on the attainment of smart cities in Nigeria. More specifically, issues relating to environmental, technological, social and legal challenges are more prominent.

Originality/value

The fuzzy synthetic approach adopted provides a clear, practical insight on the issues that need to be addressed before the smart city development can be attained within developing countries.

Abstract

Purpose

This paper aims to determine the responses of construction organisations to the Coronavirus (COVID-19) pandemic and its associated lockdown and the impact on the South African construction industry (SACI).

Design/methodology/approach

The study adopted a quantitative survey with responses sought from 825 contracting organisation’s representatives drawn from the database of the construction industry development board. The data gathered were analysed using percentage, mean item score and one-sample t-test. The reliability of the research instrument was also tested using the Cronbach alpha test.

Findings

Findings revealed that most construction organisations implemented a complete travel ban and halting all business operations on sites and offices in a bid to curb the spread of the virus. Furthermore, whilst most construction organisations envisage significant disruption in their project delivery, the problem of job losses was regarded as a short, medium and long-term impact of the pandemic. Loss of revenue, a decline in the economy and business interruption are also some of the potential impacts of the COVID-19 pandemic on the SACI.

Originality/value

The study’s findings give practical insights on the potential impact of the pandemic on the construction industry and the possible approach needed to help cushion the effect on the industry.

Abstract

Purpose

The adoption of robotics and automation (R&A) within the construction industry has been adjudged as slow, despite the possibility of it reducing the high risk posed on health and safety of humans by the activities of the industry. The call for research and development in this area of technology to improve its adoption in the delivery of construction projects is evident in past studies. Thus, this paper aims to conduct a review of R&A in construction-related fields with a view to revealing the area of focus of past studies.

Design/methodology/approach

A bibliometric approach was adopted for this study, and data used were gathered from the Scopus database. Keywords such as “robotics”, “automation” and “construction” were used to extract papers from the database. VOSviewer was used to prepare a co-authorship and co-occurrence map based on the bibliographic data gathered.

Findings

The findings revealed that focus is placed on construction automation, industrial robots and application, robots’ systems and designs, robotics in earthworks, and robots’ control and information system. Furthermore, currently, research focus in this area is tending towards a more digitalised application of R&A especially in the areas of 3D manufacturing.

Research limitations/implications

The findings of this study are limited due to the use of a single database.

Practical implications

Despite its limitations, the findings open a knowledge gap that can be explored in developing countries particularly in Africa to improve construction delivery in the continent through R&A.

Originality/value

The study adopted the bibliometric approach in mapping out research focus in R&A – an aspect of digital technology that has not been given considerable attention in recent bibliometric and scientometric studies.

Abstract

Purpose

The construction organisations in developing countries are lagging in digital technology usage; hence, they are still characterised by poor project delivery and technological backwardness. To checkmate this problem, partnering with other organisations was proposed, while critical factors needed for successful digital partnering of construction organisations were assessed.

Design/methodology/approach

The study adopted a qualitative research approach. Delphi method was used to get experts' opinion on some identified factors necessary for successful digital partnering. The experts for the study were selected using defined criteria, and a combination of interquartile deviation, Kendall's coefficient of concordance and chi-square was used to achieve robust consensus among respondents. Mann–Whitney U test was also used to ascertain the difference in perception of experts.

Findings

The findings revealed trust in digital partners, top management support and digital partner selection as the three key success factors for partnering. Other factors that can be considered alongside these main factors are the creation of a common goal, a long-term commitment, effective communication, proper conflict resolution and structured as well as continuous digital training, workshops and meetings.

Practical implications

Instead of going through the digitalisation journey alone, construction organisations, particularly in a developing country like South Africa, stand a better chance of surviving the dynamic construction and digital environment by partnering with other organisations within and outside the industry. Carefully selecting the right partner, trusting in their capability and ensuring constant commitment is necessary for the success of the process.

Originality/value

The value of this study lies in its ability to showcase the critical success factors needed for effective digital partnering, an aspect that lacks adequate consideration in the digitalisation of construction industry discourse.

Abstract

Purpose

Due to its cost savings nature and ability to ensure constant jobs for contractors, this study aims to assess the capability of the labour-only procurement system to serve as a surviving strategy for construction contractors in a challenging economy.

Design/methodology/approach

The study adopted a mixed-methods design. An interview and questionnaire were used to harness information from 98 construction participants who have been involved in labour-only procured projects. These respondents were identified through snowballing. Frequency, percentage, mean item score, Mann–Whitney u-test and content analysis were used in analysing the data gathered.

Findings

Result revealed that participants are willing to execute more projects through this system because it gives considerable cost savings for clients and provides reduction in contractor’s risk and allows them to maintain healthy cash flow. The main factors influencing its usage are the client’s decision to procure materials, need for job at hand for contractors and the need for referrals from clients for subsequent jobs.

Practical implications

Findings of this study will assist contractors to understand the potential of this procurement system as a surviving option in a harsh economy. Small and medium contractors can make use of this available opportunity of having projects at hand at reduced risk to ensure continuous cash flow to keep their organisations afloat.

Originality/value

The contribution of this study to the body of knowledge lies in its provision of a reasonable insight on the inherent nature of a procurement system as a surviving strategy for contractors unlike the usual assessment of the generic survival strategies adopted in other studies.

Abstract

Purpose

The purpose of this paper is to determine the barriers to the adoption of value management (VM) in the construction industry of developing countries with a view to providing possible measures in avoiding these barriers and increasing the usage of the system within the construction industry.

Design/methodology/approach

The level of knowledge and adoption of VM practices, as well as the barriers to its adoption in the construction industry were assessed through a survey design. Construction professionals were sampled from the six geo-political zones in Nigeria through the use of a structured questionnaire. Factor analysis was conducted on data gathered on the barriers of VM.

Findings

The study revealed a moderate level of knowledge of VM among construction professionals. This implies that the problem of VM is not that of awareness, but readiness to adopt the system. The study also reveals that the barriers to the adoption of VM can be categorised under the general stakeholder’s barriers, training and education barriers, client barriers and government/top management barriers.

Practical implications

This study was conducted across the six geo-political zones of the country as against common practice of selecting a particular region or states to represent the entire country. The findings therefore show a true reflection of the barriers to VM adoption in the country and its recommendations can to a large extent promote the adoption of VM in the country and also other developing countries where construction projects are executed through similar method, style and approach.

Originality/value

This paper highlights the possible barriers to the adoption of VM in Nigeria construction industry and provides ways to avoiding these barriers in order to achieve better quality construction and value for money.

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.
