Purpose Construction 4.0 technology is a novel innovative technology that has been proved to enhance project performance. However, information on the concept's awareness, adoption readiness and challenges in developing economies is still scanty. The purpose of the study is to appraise awareness, adoption readiness and challenges of Construction 4.0 technologies in Nigeria to bring to the fore the state of art of these innovative technologies in the study area. Design/methodology/approach The study used a convenient sampling technique to select 129 construction professionals (architects, engineers and quantity surveyors) in Osun State, Nigeria, who provided data for the study through a closed-ended structure questionnaire survey. The quantitative data supplied were analysed using frequency, percentile, Cronbach's alpha, mean score (MS) analysis and analysis of variance (ANOVA). Findings The overall awareness level of construction professionals in the study area about Construction 4.0 technologies is at a moderate level (MS = 3.03). The analysis of each component of the Construction 4.0 technologies shows that BIM (MS = 3.69) has the highest level of awareness, while augmented reality (MS = 2.51) has the least awareness level. More results show a significant difference in the opinion of the respondents, a significant difference in the respondents on 36% of the components of Construction 4.0 technologies. The adoption readiness of the Nigerian construction industry (NCI) to Construction 4.0 technologies is at an initial level (MS = 2.86). However, the 3D printing (MS = 3.36) and augmented reality (MS = 2.49) have the highest and lowest adoption readiness ratings, respectively. There is no significant difference in how respondents ranked the NCI adoption readiness on 73% of the components of Construction 4.0 technologies. The main challenges of Construction 4.0 technologies in the study area are lack of standardisation (MS = 4.02), lack of investment in research and development and cost of implementation (MS = 3.87) each. The result shows that there is perfect unanimity in the way respondents ranked the challenges of Construction 4.0. Practical implications The study provided information on the status quo of Construction 4.0 technologies in the NCI to enhance improvement in practice and the attendant project delivery. Originality/value The study attempted to bring to the fore the state of the art on awareness, adoption readiness and challenges of Construction 4.0 technologies in Nigeria. The study's information will be valuable to improve project delivery.

The purpose of this paper is to examine the effect of team members’ composition on cost and time of completion of construction projects in selected higher institutions with a view to improving construction project delivery in Nigeria. The study used the purposive sampling technique to select two higher institutions out of six in the study area, and census survey was used in selecting 35 completed construction projects executed by the institutions within the time frame 2000 to 2013. A total of 191 questionnaires were distributed to obtain information from construction team members (quantity surveyors, architects, structural/civil engineers, services engineers, contractors and clients) who participated in the selected construction projects. Mean item score and Kendall’s test were used in examining team members’ composition, while the relationship between team members’ composition and construction cost and time was tested using t-test and eta-squared. The results revealed that construction team members’ composition has a significant impact on the completion time of construction projects, though with small magnitude, while the impact of construction team members’ composition on construction cost is not significant. Also, it was revealed that some team members did not play any team role due to the fact that the main criterion for team members’ composition was knowledge, skill and abilities (KSA). The study finally recommended that a deliberate effort should be made in studying and ascertaining the team role every construction team member will play before appointing them to be member of a team, as improper team members’ composition could hamper effective construction project delivery in terms of completion time. The study is an attempt to discourage the traditional construction team members’ selection system which was based on KSAs, which is deficient under team environment.

Purpose: Studies on stakeholder management (SM) in developing countries have largely focused on public projects. However, projects of private organisations also need much improvement. The purpose of the study was to examine the extent of SM practices in building projects procured by private corporate organisations.Design/methodology/approach: Purposive sampling technique was used to select project managers (PMs) and client representatives (CRs) who have been involved in projects procured by private corporate organisations between 2008 and 2017 in Southwestern Nigeria. The PMs are comprised of executive and non-executive PMs as well as contract administrators. Both the PMs and CRs were requested to provide information on one building project in which they were involved within the period under consideration. The data collected were analysed using mean score (MS) analysis, t-test, and analysis of variance.Findings: The results showed that structured SM processes were followed in only 30.65% of building projects procured by private corporate organisations in the study area. Results further showed on a five-point scale 5-max scale that SM practice was highest with an MS of 3.92 on projects where executive PMs were appointed and lowest (MS = 2.85) on projects where PMs were appointed as contract administrators. Furthermore, it was found that respondents placed the highest premium (MS = 3.73) on stakeholder identification while they placed the lowest premium (MS = 3.45) on developing implementation strategies and stakeholder classification.Practical implications: The study examines the status quo regarding SM practice in the study area in order to devise a means of refinement.Originality/value: The study is an attempt to evaluate the premium placed on different components of SM practices by differing categories of project managers.

Introduction: This study investigates the role of Quantity Surveyors (QS) in promoting the adoption of sustainable construction (SC) practices in Nigeria, to improve construction project performance in developing economies. Despite increasing awareness of the benefits of SC, its adoption remains low in Nigeria. Thus, this study advocates for a more active role of QS professionals in enhancing SC adoption and integration in construction activities.Methods: The study employs a mixed-methods approach to data collection. In the first stage, a questionnaire was administered to 82 randomly selected professional registered Quantity Surveyors from Ekiti and Osun States, Nigeria, to gather quantitative data. In the second stage, structured interviews were conducted with 12 respondents from the initial survey, chosen for their high knowledge of SC, to gain in-depth insights and personal experience on the subject matter having obtained the participants’ written informed consent to participate in this study. Data were analyzed using descriptive statistics (frequency, percentage, mean item score) and inferential statistics (t-test), as well as content analysis for the qualitative data.Results: The findings reveal that while Quantity Surveyors possess significant knowledge of sustainable construction, their roles in facilitating the adoption of SC materials is low. The study identifies several key roles that QS professionals can play in enhancing SC adoption, including: driving stakeholder awareness, promoting life cycle costing, advising on alternative materials and their cost implications, contributing to policy formulation, advancing research and development initiatives, and conducting feasibility studies for sustainable development.Discussion: The study is limited to data collected from Quantity Surveyors in two Southwestern Nigerian states, which may not fully represent the broader national context. The sampling method might introduce a level of limitation as regards the sample size and true representation of the target population. Future research could expand the sample size and geographic scope to gain a more comprehensive understanding of the role of QS in SC adoption across Nigeria and other developing countries. This research contributes to the literature on sustainable construction by highlighting the critical, yet under-explored, role of Quantity Surveyors in improving SC adoption in developing economies. The study emphasizes the potential for QS professionals to drive significant improvements in the sustainability of the construction sector, offering valuable insights for policymakers, practitioners, and the construction industry at large.

Purpose The purpose of the study is to examine the stakeholder identification (SI) methods used in building projects procured by private corporate organisations in Southwestern Nigeria to draw a correlation between methods used for SI and project performance in the study area, thereby enhancing project performance. Design/methodology/approach The study used a census survey to purposively select 30 projects managers (who indicated from a first-stage questionnaire) that they have participated in structured stakeholder management (SM) from a list of 106 project managers and client representatives who have been involved in SM of building projects procured by private corporate organisations between 2008 and 2017 in the study area. A second-stage questionnaire was designed to elicit information from the respondents. The quantitative data that were collected were analysed using mean score (MS) analysis and Analysis of variance (ANOVA). Findings The study found that brainstorming in group meetings (MS = 4.33), interviews with the expert (MS = 3.20) and identification by other stakeholders (MS = 3.00) are the most frequently used SI methods in the study area. It was also found that the use of a questionnaire (MS = 0.87), Delphi method (MS = 0.80) and public hearing (MS = 0.57) was rare for SI in the study area. A further result showed that there was no significant difference in the opinion of project managers on 85% of methods used for SI in the study area irrespective of the procurement method employed. Practical implications The study examined the methods project managers used for SI on building projects procured by private corporate organisations to advocate for more robust and all-inclusive SI methods. Originality/value The study empirically examined methods used for SI and correlated them to project performance.
