Delivering quality projects is a real challenge for the construction sector in Libya. However, there is little information for developing quality improvement initiatives in construction companies. The aim is to present the main factors influencing the implementation of quality management systems in Libyan construction industry (LCI) through a review of relevant literature, and identify the most important factors based on a survey of managers working in construction companies in Tripoli. Of 200 hundred questionnaires distributed, 130 were fully completed giving a response rate of 65%. Among these respondents, 63% were government-related organisations, and the rest were from private sector. The data were subjected to principal component analysis (PCA), which helps interpretation of data. The analysis identified five reliable and valid quality management constructs namely top management commitment, communication, teamwork, employee empowerment and involvement, and work environment and culture. These will help to focus areas for improving quality in construction projects.

PurposeThe poor quality of construction work in war-affected regions is a significant issue. The large-scale destruction to the existing infrastructure from the war necessitates cost and time-efficient delivery of construction projects during and post-war to bring normalcy to affected lives and places. Consequently, there is always a tendency to finish construction projects in the shortest possible time on a limited budget without following the proper quality management processes. However, the poor quality of construction projects continues to affect the country's development, growth, credibility, reputation, and public safety for several years after the war. To this end, the present study was conducted to evaluate the significant attributes and factors contributing to the poor quality of construction projects in the war-affected Afghan construction sector.Design/methodology/approachA total of 31 attributes influencing construction project quality were ranked based on 110 completed survey responses collected from Afghan construction professionals. Moreover, independent samples t-test, Spearman's rank correlation test, and exploratory factor analysis were conducted.FindingsThe study found a moderate consensus between clients and contractors on attributes' rankings. In addition, the independent samples t-test showed statistically significant differences in means values of responses from clients and contractors for eight attributes. Based on factor analysis, 19 important attributes (median value greater than or equal to four) were classified into 4 latent factors – (1) poor-quality assurance and control, (2) unethical practices, (3) design and drawing errors, and (4) knowledge and skills gap.Originality/valueEvaluating the factors affecting the quality of construction projects will help clients, government departments, and construction practitioners improve the construction quality management practices. The findings will also inform the policies and procedures of international aid providers.

Road traffic accidents are a menace to a developing country such as Kenya. The National Transport and Safety Authority website records over 57,171 cases of road traffic accidents NTSA [15]. Adopting the root cause analysis technique, it is crucial to determine and to solve the cause of a problem in order to have a permanent solution for it. This study focuses on road construction projects which are the actual onset of road traffic accidents. Occurrences of road traffic accidents are dependent on various factors ranging from the ideology of road construction projects to the operation of a sound or unsound vehicle on the road. Numerous studies have been done to research on the factors influencing quality of road construction projects but little has been done to determine how contractors related factors affect quality of road construction projects. Due to the research gap in the pool of knowledge, this study is aimed at identifying and analyzing how contractor’s exposure to technology influences the quality of road construction projects. The study area that was analyzed in this project was Machakos sub-county situated in the Lower Eastern region of Kenya. The study was guided by the objective: to establish influence of contractor’s exposure to technology on quality of road construction projects. This study applied Systems theory approach. A descriptive survey research design and a cross-sectional approach was used to collect quantitative data by use of close-ended questionnaires. The total target population was 223and a calculative formula adopted from Kothari [8] was used to acquire a sample size of 141 respondents. Stratified random sampling technique was applied on the sample size of 141 respondents to classify them into homogenous groups. Questionnaires were used as the main data collection instruments and were issued to the respondents. The gathered data was analyzed using descriptive and inferential statistics with the data being presented descriptively using frequencies and percentages. Pearson’s product moment correlation procedure method was used to analyze the inferential statistic data and the results presented. In this study Spearman’s was used to measure the degree of association between the independent and dependent variables. On the influence of contractor’s exposure to technology, a composite mean of 3.74, standard deviation of 1.028 and a strong correlation value of 0.373 were achieved. The survey elicit conclusion was that quality of road construction projects in Machakos Sub-County was influenced by the independent variable.

Construction management (CM) consultant has an important role in construction project. It involves in many activities during the construction processes such as designing, tendering, consulting and managing the construction. Based on that sequence, it can be seen that CM consultant’s role starts from the beginning of the construction. Despite its important role, the service quality of CM consultant in Indonesia can still be improved. In addition, previous studies show lack of research in exploring service quality in context of CM consultant in construction projects. Therefore, the objectives of this research are to evaluate the importance level of CM consultant’s service quality items; to analyze factors of CM consultant’s service quality; and to describe the importance of CM consultant’s service quality based on owners’ perception in Indonesian building construction projects. This research is classified as quantitative and qualitative research approach. The quantitative research approach aims to evaluate the importance level of service quality items and explore factors that influence CM consultant’s service quality. The qualitative research approach aims to explain the importance of each service quality item based on owner’s perception. The survey questionnaire and interview techniques were used to gather data from project owners. There were 71 respondents who participated in this research. The collected data was analyzed by conducting relative importance index and factor analysis. The result shows the importance level of each CM consultant’s service quality item. Based on the relative importance index, the most important item is “The CM consultant is able to anticipate the problem before it happens in the project". The next most important item is “The CM consultant does a job according to the SOP that has already been agreed". In addition, the results show 10 factors influencing consultant’s service quality in Indonesian building construction projects. The examples of factors are “Understanding & providing individualized attention for the owner"; “Service oriented characteristic of the staff"; “Awareness of the project’s status and information"; etc. The findings can help CM consultant understand the service quality factors that should be provided.

Construction managers perspective on quality improvement is important, but there is no framework to expedite it in South African construction. Employing a quantitative survey approach, the survey explored construction managers’ comprehension of quality and engagement with quality management. The objective of this study is to identify the factors that have an influence on project quality, offering insight into the perception of construction managers towards these factors, in order to develop a quality improvement framework for construction managers in South Africa. The analysis, facilitated by SPSS v27, incorporates descriptive and reliability statistics, as well as KMO and Bartlett’s test. The results show that construction managers’ emphasis on quality is pivotal to project success. The research found that construction managers exercise meticulous control over quality by overseeing deliverables for accuracy and flawlessness. This vigilance is achieved through constructability reviews, meticulous planning, seamless organisation, and coordinated teamwork. These results are used to propose a quality improvement framework comprising five categories, namely the construction manager’s understanding of quality; the construction manager’s perspective on quality; the implementation of a QMS; internal and external factors that affect quality, and the benefits of having a skilled construction manager on board. The integration of these five factors within a comprehensive framework empowers construction managers to effectively manage and improve the quality of construction projects. This approach ensures that projects are executed with precision, adhere to industry standards, and meet or exceed client expectations, thereby enhancing the overall success and reputation of the construction management firm.

Following decades of quality management featuring in higher education settings, questions regarding its implementation, impact and outcomes remain. Indeed, leaving aside anecdotal case studies and value-laden documentaries of best practice, current research still knows very little about the implementation of quality management in teaching and learning within higher education institutions. Referring to data collected from German higher education institutions in which a quality management department or functional equivalent was present, this article theorises and provides evidence for the supposition that the implementation of quality management follows two implicit logics. Specifically, it tends either towards the logic of appropriateness or, contrastingly, towards the logic of consequentialism. This study’s results also suggest that quality managers’ socialisation is related to these logics and that it influences their views on quality management in teaching and learning.

Purpose: The purpose of the study was to assess the impact of risk management on the successful completion of construction projects in public primary schools in Dodoma Urban District, Tanzania. Methodology: Explanatory research design were used. Structured questionnaires were used for data collection from 320 respondents who were selected using simple random sampling technique. The collected data were analysed using descriptive statistics and multiple linear regression analysis. Findings: The study concluded that effective risk management through identification, analysis and regular monitoring is key to successful construction projects. These elements work together to address challenges, ensure timely completion, control costs, improve quality, and promote accountability and transparency in project management. Unique Contribution to Theory, Policy and Practice: The study concluded that effective risk identification, risk analysis and regular risk monitoring enhance timely completion and improve the overall quality of construction projects. The findings contribute to theory by empirically strengthening Risk Management Theory and demonstrating its applicability in public primary school construction projects. They further inform policy by highlighting the need for institutionalized risk assessment guidelines, capacity-building and consistent monitoring frameworks within local government construction procedures. In practice, the study provides actionable insights for project managers and contractors to adopt structured, proactive risk management approaches that minimize delays, cost overruns and quality shortcomings.

Quality in construction projects is important in terms of providing safe, durable end products at an economical cost, but evaluation of the efficiency of Quality Management Systems (QMS) is a long-standing incongruent issue due to haphazard measures and various implementation processes. The present paper will explore QMS effectiveness in the construction sector by conducting a literature and industry review to determine the outcomes of performance and identifying factors that lead or contribute to success or failure. The goals of the study include assessing the average QMS elements, such as ISO 9001 guidelines and TQM operations, gauging performance through metrics, including defect elimination, cost reduction, and conformity rates, and proposing the strategies to improve the performance of the system. The paper takes a statistical approach to designing the research findings using data aggregated in peer-reviewed journals and reports in the industry. Findings indicate QMS results in 15-25 percent defect eliminated and 10-15 percent cost savings and leadership and training are the main facilitators albeit obstacles remain such as resource insufficiency. The work will also provide construction professionals with a useful reference point in terms of assessing the effectiveness of QMS, facilitate the compatibility when applied together with information technology such as BIM, and facilitate a more sustainable activity by avoiding unnecessary pieces of work on rework.
