Disruption caused by coronavirus disease 2019 (COVID-19) to the ways and manners businesses are conducted worldwide is phenomenon. The study therefore examined the survival strategies adopted by quantity surveying firms (QSFs) in Lagos State, Nigeria, with the intention of improving their performance.

This study used a systematic sampling method to select three QSFs from 20 local government areas in the state. Of the 60 QSFs contacted for interview, only 42 agreed to participate. A questionnaire was designed to collect the required qualitative information, which was then analyzed using content analysis.

The results revealed that the main survival strategies adopted by QSFs in Lagos State, Nigeria, during the COVID-19 disruptions were downsizing, contract staffing, salary cuts, work from home and service negotiation strategies.

Due to the chosen research approach, the research results may not be generalizable. The incidence of the pandemic and the socio-economic situation of the study area have to be considered.

The survival strategies employed by QSFs in Lagos Nigeria in the middle of COVID-19 are palliative (unsustainable) as the impact of the disruptions is biting hard on QSFs in Lagos Nigeria as such a more robust and sustainable method to enhance the performance of QSFs in the study area.

This study attempted to unearth the survival strategies of QSFs amidst COVID-19 in Lagos State, Nigeria, with the aim of improving the performance of such firms.

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.

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).

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.

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.

The study empirically examined methods used for SI and correlated them to project performance.

The study assessed the stakeholders prioritization of key performance indicators (KPIs) on public and private tertiary educational projects in Osun State, Nigeria intending to enhance their performance.

The study used a total enumeration survey to purposively select built environment professionals working in the Physical Planning and Development Unit (PPDU) and procurement units of 17 tertiary educational institutions (7public and 10 private) in Osun State Nigeria for data collection. A quantitative research approach was adopted for the study using a questionnaire. A total of 102 questionnaires were retrieved from the respondents and used for analysis. Analysis of data was done using frequency, percentile, mean score (MS), Cronbach's Alpha coefficient, t-test, and Analysis of variance (ANOVA).

The study found that in the overall opinion of the respondents the most prioritized KPIs for tertiary educational projects are for the project to meet specifications (MS = 4.17), the project must be on time (MS = 4.01), and efficient use of resources (MS = 3.96). The important KPIs for the public tertiary educational projects is that the project should meet specifications (MS = 4.08), deliver the projects on time (MS = 3.96), and be under cost (MS = 3.84). While, the most prioritized KPIs for private tertiary educational projects are for the project to meet specifications (MS = 4.25), efficient use of resources (MS = 4.14), on time, and doing the right thing (effectiveness) (MS = 4.06) each. More findings indicated that there is no significant difference in the manner built environment professionals prioritized KPIs. However, there is only a 7% significant difference in the manner professionals working in the public and private tertiary educational institutions in Nigeria ranked KPIs.

There is a significant difference in the ways and manner built environment professionals working with the public and private tertiary educational institutions in Nigeria view resource utilization on their projects. As such, working environment either as public or private has a significant impact on resource utilization for tertiary educational construction projects.

The study compared opinions of professionals working with public and private tertiary educational institutions on KPIs to enhance project performance.

Advocates of structured stakeholder management (SM) processes have emphasized the use of the appropriate strategies as the most important process in SM. Yet, research effort in this regard in developing countries has been inadequate. The purpose of the study was to examine the SM strategies used on building projects procured by private corporate organisations in south-western Nigeria to enhance project performance.

The study used a census survey to select 30 projects managers who indicated (from 106 who responded to a first stage questionnaire) that they have participated in structured SM in the study area between 2008 and 2017. A second-stage questionnaire was designed to elicit information from the respondents. Data analysis was done with the use of frequency, percentile and mean score (MS) and analysis of variance (ANOVA).

Stakeholders with high power and high interest were managed with the use of “collaborate/partner” strategy (MS = 3.86), stakeholders with high power and low interest were “kept satisfied” (MS = 4.09), stakeholders with low power and high interest were managed by using “keep them informed regularly” strategy (MS = 4.10) and stakeholders with low power and low interest were managed using “monitor and respond when necessary” strategy (M = 3.94). Further results show that static stakeholders with high power were managed by using the “monitor constantly” strategy (MS = 4.11), stakeholders with high power, high legitimacy and high urgency were managed by adopting the “keep satisfied” strategy (MS = 4.26), to manage non-supportive stakeholders, project managers adopted the “keep satisfied” strategy (MS = 4.18) and supportive stakeholders were managed by using “involved” strategy (MS = 4.02). More results showed that there is no significant difference in the opinion of project managers on SM strategies employed irrespective of procurement method.

The study provided a guide to project managers on the appropriate SM strategies to use for future projects.

The study was an attempt to appraise the SM strategies in relation to the procurement methods and their relationship with project performance.

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.

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.

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.

The study examines the status quo regarding SM practice in the study area in order to devise a means of refinement.

The study is an attempt to evaluate the premium placed on different components of SM practices by differing categories of project managers.

The purpose of this study is to examine the impact of coronavirus disease 2019 (COVID-19) on indigenous contractors in a developing economy with a view to enhancing their performance.

The study used a purposive sampling technique to select 37 indigenous contractors with ongoing construction contracts in Osun State, Nigeria who provided data for the study. A structured interview protocol was used to elicit the required information from the interviewees and frequency, percentage and content analysis were used for data analysis.

The results showed that the critical impact of COVID-19 on indigenous contractors in a developing economy is: time overrun, loss of profit and creation of dispute. Further results showed that other impacts are a disruption in supply of labour, locally sourced materials are with additional cost, the additional cost of implementing COVID-19 protocols, difficulty in sourcing imported materials and absence of new jobs with the corresponding retrenchment of workers.

The study recommended special palliatives for the indigenous contractors from the government so as to cushion the impact of the pandemic on them, thereby enhance their survival and performance. A special arbitration panel is set up in each state of the federation to look at disputes arising from the aftermath of the pandemic, this is with a view to adequately compensate indigenous contractors with genuine and properly compiled claims. inferring from the findings of the study, it suffices to say that the severity of the impact of the pandemic is very high on indigenous contractors in developing economies, as such a better preparedness strategy could lessen the impact of such pandemic in the future.

The study is an attempt to unearth the impact of COVID-19 on indigenous contractors with ongoing construction contracts in a developing economy. The study will be of value to construction stakeholders in providing the information needed to devise strategies to minimise the impact of a pandemic on indigenous contractors in future projects thereby enhance their performance.

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.

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.

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).

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.

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.

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 compare the cost and time performance of construction projects in public and private universities in Osun State, Nigeria.

Purposive sampling technique was adopted to select four universities (two public and two private) used for the study. Archival data on 40 completed construction projects (ten from each university) was used in the study. Data were analysed with percentile and t-test.

The study showed that only 35 per cent of the construction projects in public and 10 per cent of those in private universities were completed at the estimated cost. There were no construction projects completed within the planned time in public universities, but 20 per cent were completed within the planned time in private universities. The t-test showed there is no significant difference in performance of construction projects in public and private universities in Nigeria. The study concluded that time performance of public and private universities in Nigeria was still below acceptable international best practices.

The findings of this study are limited to universities’ construction projects and may be of little application to other construction projects outside university settings.

It is recommended that construction stakeholders be more proactive in ensuring that significant improvement is achieved in cost and time performance of construction projects both in public and private universities; the clients need to be more detailed in their briefs and requirements, the designers (architects and engineers) need to be more precise and avoid varying their designs, the quantity surveyors should use their professional competency in cost engineering adequately and the contractor should avoid spurious claims that result in increase in construction cost and time so that performance of construction projects can be improved.

The study is an attempt to compare cost and time performance of construction projects in public and private universities in Osun State, Nigeria.
