The study objective was “An assessment of critical factors affecting quality performance of government financed construction projects in Tanzania”. The study was initiated as much of government financed construction projects are executed with variations on delivering time, cost and quality. The study identified factors if not considered can lead to poor quality performance of projects. Closed end questionnaire consisting of 20 performance factors were issued to 80 respondents dealing with construction related activities, they were required to rank them on a 5 point Likert scale. Data analysis was done using Statistical Package for Social Sciences version 16 (SPSS). The findings revealed that the critical factors that have direct impact on quality performance of government financed construction projects are; project financing processes, experience of contractors in construction industry, project technology, availability of plant and equipment, procurement system and processes as well as the project manager knowledge and skills. A multiple regression model developed showed a positive linear relationship between project quality performance and the critical quality performance factors. All the critical quality performance factors had positive coefficients with an acceptable level of significance. The study recommends further studies on the economic and social factors that hinder women participation in construction relation activities and how training and learning opportunities for continuous improvement will have positive impact on the performance of construction projects.

Failure Factors

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.

The Impact

Background: The construction industry in Nigeria, is pigeonholed by poor quality of construction products as a result of the inherent corruption in the country. Lack of purposeful leadership and inappropriate choice of leadership styles in the industry have been attributed to project failure. Abandoned and failed projects are more predominant in the public sector which litters every corner of the country. Objectives: The objective of this paper is to assess the impact of leadership styles on quality performance criteria of public projects in Nigeria. Methodology: A total of 43 questionnaires were distributed to 3 key groups of respondents (Quantity Surveyors, Builders, and Architects) who are project managers in Nigeria. Descriptive and Inferential statistics were used to analyse the data using the Statistical Package for Social Sciences (SPSS). Likert Scale was used to measure the independent variables (leadership style): facilitative, coaching, delegating and directing; and the level of achievement of projects based on the dependent variables (quality and function performance criteria) which are: achieving highest aesthetic quality; and functional building that fits its purpose. Findings: The study revealed that Directing is the major leadership style used by project managers in Nigeria. Amongst the leadership styles which has the most impact on quality performance indicators is also directing which has the most relative influence on achieving highest aesthetic quality and functional building that fits its purpose. Conclusion/Recommendation/Way forward: The underlying relationship between Directing leadership styles and the performance criteria of achieving highest aesthetic quality and functional building that fits its purpose will be beneficial to the Nigerian construction environment.

Level Of Significance

Poultry egg production is an economically viable investment among Agroforestry farmers in Southwestern Nigeria but paucity of funds and high cost of inputs are major problems in their business operations. This study focused on the effects of accessibility and non-accessibility of Agroforestry farmers to credit on poultry egg production. Data were randomly collected from 120 poultry farmers with a structured questionnaire which comprised of 60 credit beneficiaries (CB) and 60 non-credit beneficiaries (NCB) Agroforestry farmers. The data were analyzed with mean, percentages, frequency distribution, logit and multiple regression analyses. The results of the analyses indicated that the mean age of the CB and NCB Agroforestry farmers were ±46 and ±56 years respectively. Majority of the farmers were married CB (77.4%) and NCB (81.0%). The logit regression analysis revealed that the age of the respondents had a positive relationship with access to credit at 5% level of significance. Multiple regression model for credit accessed farmers indicated that age, family size, drug quantity are positively related to output and are significant at 10% and 1% levels. Multiple regression result for NCB farmers shows that the quantity of drug used is positively related to the egg output at 1% level. The hypotheses tested show that there was a significant relationship between socio-economic characteristics and the egg production in the study area and; between the output of farmers who are credit beneficiaries and non-credit beneficiaries. The major constraints to poultry production in Agroforestry system were limited finances, high cost of inputs and poor quality of day old chicks. Accessibility to formal credit facilities has a key role to play in Agroforestry poultry farming. Individuals, Governments and NGOs should therefore facilitate empowerment of youths in poultry egg production.

This paper assessed the occurrence and severity level of various factors causing time and cost overrun in construction projects of Pakistan. Investigation was carried out through questionnaire form prepared based on 55 common factors identified from literature. Survey was done amongst the representatives of the contractors involved in handling construction activities in Pakistan. A total of 46 responses gathered against 100 distributed forms were analysed statistically. The results obtained from the analyses based on Average Index values revealed that delay in obtaining permits from the governmental agencies, financial difficulties are common issue faced in construction works of Pakistan. The study also revealed that high cost of machinery & its maintenance, inadequate planning & scheduling and slow information flow between parties have significant effect on time overrun cost while critical factors affecting cost overrun are high cost of machinery & its maintenance, unsuitable construction methods and lack of experience of contractors in affecting project cost. The findings of this study will be helpful for the practitioner in planning for achieving timely completion of the projects and also within the estimated cost.

Purpose This paper aims to analyse the factors affecting the performance of large construction projects in Sri Lanka. The causes, impacts and mitigations in association with the critical factors are explored and discussed. Design/methodology/approach The research focuses on the evaluation and perspectives of clients and contractors of large projects in Sri Lanka. Combined quantitative and qualitative methods were applied in this research. Initially, a questionnaire survey was conducted with clients and contractors involved in large projects to evaluate the factors affecting the performance of projects and to identify the ten most critical factors. Interviews with the clients and contractors of three large projects were conducted to examine the causes and impacts of the critical factors and the approaches used to mitigate them. Findings Significant differences in the factors were observed for more than 40 per cent of the total factors under study, the contractors assigning more weight to most of the factors than the clients. The study identified nine internal factors and one external factor as the critical factors. Of these, seven were related to the contractors, which suggested that the contractors have greater roles in defining performance. Lack of management and technical skills of the parties involved, human capacity, lack of understanding and knowledge of the local context, changes in government policies and political interference were identified as significant causes of the critical factors. Originality/value The study analysed the factors affecting the performance of large projects in Sri Lanka, which, at the time of research, had just ended a 26-year-long civil war and was pushing the construction of large projects to be competitive. The challenges faced in this effort were explored as lessons learnt that might improve the efficiency and effectiveness of infrastructure development in Sri Lanka. The combined quantitative and qualitative methods applied in this study are expected to provide new insights in the project performance research, especially the interviews of the critical factors to gain an understanding on how the factors occurred and manifested themselves in real projects. The findings are, however, expected to be applicable to other developing countries that are currently aggressively developing their large infrastructure.

One of the critical decisions taken by contractors is whether or not to bid for a project. This is due to the complexity and uncertainty surrounding this decision, which is influenced by many factors. Given the above challenge, this study aimed to uncover the critical factors affecting the contractors’ bidding decisions in Saudi Arabia-based construction projects. A questionnaire survey, which consisted of 31 factors, was distributed to first-, second- and third-grade contractors. In total, 67 responses were obtained. Median and relative importance index (RII) techniques were adopted for ranking the most critical factors. Based on the received responses, the top six critical factors were “size of the job”, “type of the job”, “company’s strength in the industry”, “designer/design quality”, “rate of return”, and “project cash flow”. The least significant factors were “job start time” and “labor environment (union/nonunion/cooperative)”. The findings of this study show a level of agreement among all contractors about the critical factors. The findings would benefit contractors and subcontractors by increasing their understanding of the major factors affecting the bidding decision process. Contractors armed with such valuable information will be better able to enhance their bidding decision-making process in terms of efficiency and effectiveness.
