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.

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.

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 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 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.

Lack of strict compliance to the principles of total quality management (TQM) by construction organizations has brought about poor quality of the finished building projects. This has been blamed for the incessant structural failure reported in Nigeria. This study appraised TQM implementation in the Nigerian construction industry, with a view to mitigating structural failure rate of construction projects. To achieve this aim, the study aims to assess the practice level of TQM and the factors hindering TQM implementation on construction projects.

The study utilized a well-structured questionnaire and convenient sampling method in the gathering and sampling of data among construction professionals in Imo state, Nigeria. Data analyses were done using, frequency, percentage, mean analytics and Pareto analysis.

The study revealed that major practice of TQM principles with respect to structural failure rate are purchasing: ensuring the procurement of materials of the specified quality standard, ensuring the use of a quality improvement construction process of the organization, site management responsibility: this entails ensuring quality supervision by the project management leadership and monitoring and control of quality during the construction to guarantee firm observance quality standards. Also, the major factors hindering TQM implementation on construction projects are: inadequacy of the necessary machineries, equipment, tools and facilities for the effective execution of work on construction site; breakdown in communication and information exchange between the management and supervisory teams on site; poor attitudes and strategies toward maintenance of equipment, tools and machines; and absence of prompt salary and incentive payment. It was recommended that construction firms must require the suppliers of construction materials to strictly comply with quality specification evidence in quality certification of delivered materials to mitigate structural failure.

This study appraised TQM implementation in the construction industry of Nigeria, with emphasis on Imo state. The study underscores the practice level of TQM and the key factors hindering TQM implementation on construction projects. Following the localized geographical limitation of the study area, a similar research in other part/states of Nigeria or even in other developing countries of African is necessary.

The practices level of TQM and the factors hindering TQM implementation were identified. This will be useful in guiding construction firms, other industry's key stakeholders and regulatory agencies in bringing about a sustainable quality management system for improve profit and value maximization and avoiding incessant structural failure.

This is one of the few studies that have assessed the practice level of TQM and the factors hindering TQM implementation on construction projects in Nigeria. This study took place in Imo state with records of periodic structural failure and building collapse.
