With devolved government system in Kenya, there has been a rapid increment in public construction projects. Nevertheless, performance of these projects is questionable in most counties. In Makueni County, several construction projects have had their performance compromised as evidenced by their delayed completion. The inherent risk involved in the projects is among the major reasons that lead to projects performing poorly. However, none of the existing studies have assessed how risk governance influence project performance in construction projects in Makueni County. This has resulted to lack of adequate empirical insights to guide in developing strategies for enhancing performance of construction projects in Makueni County as far as risk governance is concerned. Therefore, this study investigated the interplay between risk governance and performance of construction projects in Makueni county, Kenya. The primary objectives were to investigate the influence of resource risk management, budget control risk management and litigation risk management on performance of construction projects in Makueni County, Kenya. The research applied the descriptive research design whereby 24 projects in construction industry in Makueni County completed in year 2018/2019 were studied. The project manager, project supervisor and contractor handling each of the projects constituted the respondents. A census approach was used and thus a total of 72 respondents were targeted. To collect data, a questionnaire was administered to the respondents. Data analysis was based on descriptive and inferential statistics. The findings indicate that resource risk management in construction projects in Makueni County is good. However, inadequacy of financial resources for the project activities is a major issue. Budget control risk management and litigation risk management were also good. It was found that resource risk management, budget control risk management and litigation risk management had a positive influence on the performance of construction projects in Makueni County. The study concluded that performance of construction projects in Makueni County is significantly affected by budget control risk management while resource risk management and litigation risk management have no significant effect. The study recommends that the county government of Makueni should set aside adequate financial resources for the various construction projects to be implemented.

Project management help ensure the efficient and effective performance of projects. Consequently, in the last five years, Nairobi City County has witnessed numerous residential buildings collapsing due to poor project performance. Besides, limited studies have studied the project management practices that residential construction project managers should adopt to boost project performance as far as Nairobi city county is concerned. Therefore, the proposed study aims to investigate how project management practices affect the performance of construction projects in study area, especially in residential spaces. In realizing this aim, the study focused on realizing the objective of project stakeholder management on the performance of construction projects. The stakeholder theory informed the study’s variable. The variables examined were project stakeholder management (independent variable) and project performance (dependent variable). The descriptive research design guided the data collection and analysis processes. Data was collected from the targeted 50 residential construction projects completed within the last five years across Nairobi City County. The respondents comprised the targeted projects’ contractors, project managers and NCA employees. Semi-structured questionnaires were the primary data collection instruments, where the researcher administered questionnaires to the selected respondents to ensure the gathering of qualitative and quantitative data. 282 respondents participated in the study, who completed and returned the instruments after administration. A pilot test and the Cronbach alpha values for all the study variables met the recommended 0.70 threshold, guaranteeing reliability. The proposed study aimed to ensure that the questionnaires maintained great extents of sampling, construct, and face validity. The obtained data was analyzed using thematic analysis for the qualitative data and descriptive and inferential statistical analyses. Findings indicated that stakeholder management positively affect project performance, with project resources scheduling having the greatest influence. The study emphasized the importance of effective resource allocation, timely regulatory compliance, and strong stakeholder engagement in achieving project success. Recommendations included adopting digital tools for resource management, appointing a regulatory liaison, implementing continuous quality improvement frameworks, and using digital platforms for stakeholder engagement. Future research could explore the influence of leadership styles and external economic factors on project performance.

This paper aims to examine the effect of selected factors that link to completion of NSSF construction projects and how they are influenced by the various critical factors. The main objective was to establish the critical success factors and their effects on performance of construction projects. Four theories namely Game theory, Principal-Agent theory, Construction Management, and Soft Value Management (SVM) theory served as the foundation for this research. Descriptive research design was employed for data collection, analysis, presentation and interpretation.The target population was 512 stakeholders from six complete commercial and residential projects. Purposive sampling was used to select 84 participants for the study. Semi-structured questionnaires were used in the study to collect data. The data was analyzed using SPSS whereby descriptive and inferential statistics were used. The results show that the R-square value was 0.282 and R was 0.531. An analysis of variance (ANOVA) was significant at p=0.001 with an F statistic of 9.961 indicating that the model used was fit for the data. The data also revealed that client variations (p= 0.05), financial availability (p = 0.047), and construction disputes (p = 0.001) are statistically significant determinants affecting the performance of NSSF construction projects. The main findings of the study demonstrate that the key critical success factors used in this study affected the performance of NSSF-completed construction projects either positively or negatively. The study recommends that companies should adhere to the principles that safeguard project management to adequately manage the critical factors and ultimately minimize project delays.

Stakeholder management is a pivotal aspect of construction projects funded by county governments in Kenya. Effective stakeholder management is essential for aligning project objectives with the diverse needs of all the stakeholders involved. In Kenya, public infrastructure projects often face challenges such as delays and budget overruns. Therefore, robust stakeholder management practices are essential for ensuring successful project implementation. The specific objectives of this study were to determine the current state of stakeholder management performance in County government-funded construction projects, to establish the existing stakeholder management practices in County Government-funded construction projects, and to establish the influence of stakeholder management practices on stakeholder management performance in County Government-funded construction projects. The study adopted a survey research design. The data was collected using questionnaires and measured using a 5-point Likert scale. Simple stratified sampling was used to identify the 254 respondents. The respondents included contractors, project consultants, end users, ward development officers, PMC representatives, ward administrators, and village administrators. The collected data was coded and entered into Statistical Packages for Social Scientists (SPSS) and analysed using descriptive statistics. The multiple regression analysis method was used to determine if a relationship existed between the dependent and independent variables. The overall level of stakeholder management performance had a mean of 2.25. This research established that stakeholder management practices are statistically significant in explaining the stakeholder management performance in construction projects funded by the County in Machakos County. Additionally, this study concluded that the level of stakeholder management performance was low in Machakos County. Finally, the study recommended that counties should prioritise stakeholder management training through well-organised awareness campaigns.

PurposeThe construction sector plays a vital role in the economic progress of every nation, including Tanzania. Notwithstanding its significance, the industry experiences poor performance. This study aims to assess the impact of procurement contract risk management on the performance of force account (FA) construction projects, using a regulatory framework as a moderator.Design/methodology/approachThe cross-sectional research design was used, and data was collected by using a structured questionnaire. The study employed a sample size of 318 respondents to analyse data by using partial least square structural modelling (PLS-SEM).FindingsThe findings revealed that supply risk management, procurement internal control system and procurement contract administration influence the performance of FA construction projects. Additionally, the study confirms that the regulatory framework strengthens the relationship between the procurement internal control system and procurement contract administration with the performance of FA construction projects. Therefore, procurement contract risk management, as moderated by the regulatory framework, plays a significant role towards the performance of FA construction projects.Practical implicationsThese findings have significant implications for practitioners and policymakers involved in FA construction projects in the public sector, as they highlight the importance of procurement contract risk management in achieving the successful performance of FA construction projects.Originality/valueThis study contributes to the ongoing discussion about the performance of construction projects, especially those under the FA procurement. It also contributes to the literature on public construction projects in developing countries.

Sustainability is defined as meeting the demands of the present without compromising the ability of future generations to meet their own needs. This study focuses on the sustainable construction strategies used in the Kingdom of Bahrain in terms of sustainable construction technologies and management strategy linked to the environment and the significant relationship between the management strategy and construction technologies used for sustainable building construction. This study employed the descriptive-correlational method of research using a questionnaire for gathering data about the sustainable construction strategies used in Bahrain. The data gathered were analyzed using the weighted mean and Pearson’s correlation coefficient to determine the degree of correlation between construction technologies and management strategy. SPSS software was used in the calculation. Results show that management strategy linked to the environment is often practiced in around 75% of all projects delivered while general sustainable construction methods, energy and material-based techniques, and waste-based techniques are sometimes utilized in around 50% of all the building projects delivered. In addition, the utilization of these sustainable construction technologies is the result of a management strategy linked to the environment which the respondents rated as often practiced for all projects that were delivered. This implies that management strategy in protecting the environment in Bahrain is often practiced in construction for 75% of the projects. From the results of the study, a model of sustainable building construction in the Kingdom of Bahrain was derived to achieve sustainable building construction. This includes the management strategies needed by the different stakeholders like construction firms and government agencies to carry out the implementation of sustainable construction and sustainable construction techniques (e.g., waste management, insulating materials, building envelope with thermal properties, building management system, and efficient fixtures).

Sustainable buildings contribute significantly to achieving sustainable development and provide many benefits. However, sustainable building construction projects are riskier than traditional construction projects. Thus, this research aimed to identify and assess the risks in sustainable construction projects in Jordan based on their probabilities of occurrence and impacts on time and cost. For this purpose, a literature review and structured interviews were performed to identify the risks. Additionally, questionnaire surveys were conducted, and the relative relevance index and analytic hierarchy process were utilized to assess the probabilities and impacts of these risks on time and cost. After that, a focus group discussion was conducted. According to the the risks’ probability and impacts on time and cost, the top-scoring risks include changes to the original design, budgeting inaccuracies owing to a lack of experience with sustainable building projects, additional costs incurred as a result of the use of sustainable building construction materials and equipment, inadequate or inaccurate sustainable design information, insufficient funds from clients, inadequate project planning for a sustainable building project, a tight project schedule for a sustainable building project, and insufficient identification of sustainable construction’s scope. This research contributes to the body of knowledge and practice by providing a novel integrated method for assessing risks in sustainable building construction projects in Jordan.

Construction industry is crucial for the economy of any country. Learning from failure is important to reach effective quality performance in construction projects. This will, in turn, contribute to the development of the construction industry and the country as a whole. Although quality is an important criterion in the project management success, but it receives less attention than cost and time in project management literature. Moreover, critical success factors (CSFs) are identified more often than critical failure factors (CFFs) in construction literature. Hence, there is still a lack of attention on critical failure factors affecting quality performance in construction projects. Construction industry is full of uncertainties, especially in the current era of COVID-19 Pandemic. This adds to the necessity of studying critical failure factors in construction industry. This study aims to identify the critical factors that have adverse effect on quality performance in construction projects, address their relative importance, and suggest ways to attain good quality performance in construction projects. Based on literature review, an initial list of failure attributes of quality performance in construction projects was prepared. Then it was refined based on suggestions from experienced professionals in the construction industry in the Jordanian context. A questionnaire was distributed to experts in the construction industry. The responses were analyzed using Statistical Package for the Social Sciences (SPSS). The analyses used here are factor analysis and tests of its appropriateness. Using these analyses, the most critical factors that impede quality performance in construction were identified and ranked. The study revealed that the most influencing failure factors are the managerial factor, the culture and environment factor, and the contractor factor.

This study explores integrating Building Information Modeling (BIM) technology into risk management practices for construction projects, aiming to enhance project performance through improved risk identification, assessment, and mitigation. The research employs the Analytical Hierarchy Process (AHP) to prioritize BIM-based strategies across multiple risk management dimensions, including technical, financial, sustainability, and time management. The findings demonstrate that BIM-based financial strategies rank highest among BIM-driven risk management, followed by sustainability and time. In contrast, technical, operation, and maintenance capabilities have the lowest rank. Given the high priority of BIM financial strategies, they have been applied to conduct sensitivity analysis; the sensitivity analysis results demonstrate the dynamic nature of a BIM sub-criteria strategy in response to changes in the weight of financial considerations. As financial concerns diminish, the shift towards sustainability, health, safety, and time efficiency underscores the importance of a more balanced approach in BIM strategy prioritization. BIM-based risk management improves project outcomes by enabling real-time data-driven decision-making, enhancing stakeholder collaboration and optimizing resource use, cost control, and sustainability. This research contributes to theoretical and practical advancements in construction risk management, suggesting that BIM can be a transformative tool for optimizing project performance while addressing the complexities and uncertainties inherent in the construction industry.

PurposeThe objectives of this paper are to examine the impact of psychological contract on project performance in private construction projects and to investigate if the positive effect of psychological contract on project performance can be mediated by inter-organisational teamwork.Design/methodology/approachMultiple regression analysis and mediation analysis were applied in this study to conduct the proposed hypotheses. Data were collected via questionnaire surveys from the construction professionals working for contractor firms on private construction projects.FindingsThe result of the multiple regression analysis indicated that psychological contract between contractors and owners is significantly related with project performance in construction projects. This study examined five psychological contract components, but the most important element was found as trust which can influence every aspect of project performance. Fairness is another key factor that can improve project performance in terms of budget and quality. Further, the findings of the mediation analysis revealed that inter-organisational teamwork has a mediating effect on the relationship between psychological contract and project performance.Originality/valueThis paper presents the important role of psychological contract between contractor and owner organizations in construction projects that can affect project performance. The study also highlights the significance of inter-organisational teamwork as a mediator to the relationship between psychological contract and project performance.
