Delays and disruptions are among the challenges faced in the course of executing construction projects in Nigeria. Delays as well as disruptions are sources of potential risks that current studies are looking into ways to manage such as technical, social, economic, legal, financial, resource, construction and commercial. The purpose of this research is to assess causes and effects of delays and disruptions in the Nigerian construction industry. This study is descriptive, designed to obtain views from clients, consulting firms, regulatory boards and construction firms in regard to causes and effects of delays in construction projects. Two sampling techniques were used to select respondents namely: purposive and random sampling. Literature review, questionnaires techniques were used to collect data for the study. Findings reveal that the main causes of delays and disruptions are: design changes, delays in payment to contractors, information delays, funding problems, poor project management, compensation issues and disagreement on the valuation of work done. On the other hand, time overrun, cost overrun, negative social impact, idling resources and disputes are the main effects of delays and disruptions. The study concludes that there still exist a number of causes of delays and disruptions and their effects put construction projects at great risk that have an effect on their performance. It is therefore recommended that adequate construction budget, timely issuing of information, finalization of design and project management skills should be the main focus of the parties in project procurement process.

Purpose The purpose of this study is to contribute to the theory and practice of project management in the construction industry by identifying the primary causes and extracting the underlying causes of construction delays and providing recommendations on delay mitigation measures. Design/methodology/approach AA survey was used to identify the importance of 47 causes of delays. The relative importance index was used to rank them, factor analysis was applied to extract the underlying causes and focus group interviews were used for discussion and development of mitigation measures. Findings Six of the ten most important causes are in the top ten universal delays in construction projects. Factor analysis revealed six underlying causes: improper planning, poor consultant performance, inefficient site management, owner influence, bureaucracy and sub-standard contracts. Practical implications The owner/sponsor/client must have adequate engineering and project management skills to be able to evaluate proposals and contractors more accurately, economically and technically. The bidding and contract award process should focus on the most economically advantageous proposal and contracts should provide for mechanisms for managing risks while executing projects. Contractors should select reliable, high-quality subcontractors and suppliers and should have competent site managers. Originality/value This work expands and improves the understanding of the causes of delays in construction projects by providing an empirical study of the causes of delays and respective mitigation measures in Portugal.

Cost overrun in construction projects is a common issue affecting project performance, and Gas-Oil con­struction projects in Iran are no exception. This paper presents the results of a questionnaire conducted to identify and evaluate the relative importance of the significant factors contributing to the Gas-Oil construction industry of Iran as a case study for developing countries. The survey respondents included project owners, contractors and consultants in­volved in Iranian Gas-Oil construction projects. The results of the survey revealed that the main causes of cost overrun in this industry include inaccurate cost estimations, improper planning, frequent design changes, inadequate labour/skill availability, inflation of costs of machinery, labour, raw material and transportation prices. The first three factors are the project consultants’ responsibility and the appointment of qualified consultants and personnel training are strongly recommended to alleviate cost overrun. The paper also reviews and compares findings of a set of similar researches in a number of developing countries.

Causes Of Delays

the planned cost and duration of the project are two criteria for a successful project and successful project management. In Iraq, construction projects regularly faced delays and cost increases. The purpose of this study is to identify and rank the causes of delays and cost increases, in terms of their degree of occurrence, severity and importance. Objectives of the study: the study of the reasons leading to excess cost and duration Research technique: a questionnaire was used to identify the causes of this situation. The questionnaire was compiled through a survey of 57 Iraqi construction experts. Twenty reasons for delays and cost increases corresponding to the construction and industrial construction projects were identified and ranked in terms of importance. Statistical analysis was performed using SPSS packages. Conclusions: The results showed that the main factors affecting the cost and duration of the project are: financial difficulties of the owner (77.61%), poor site management (77.1%), financial difficulties of the contractor (70.0%), poor assistance in project management (76.9%), design changes (76.7%). Spearman's correlation tests showed that there were no differences in views between the three main participants in the project. These results may encourage practitioners to focus on the problem of delay and the increase in value that may exist in their current or future projects.

As amount of information in construction industry is growing, the role of information system in project management is becoming increasingly important. With the emerging IT application to the advancing construction industry, construction project management system with advanced technology has been progressed vigorously to improve construction productivity and management efficiency. Recently, a web-based Project Management Information System (PMIS) is developed to support decision-making process by efficiently managing project related information generated from various discipline. Many firms are in the process of developing the PMIS system or already have been applied the system to various projects. However, PMIS is still in its early stage of development to be applied at industrial plant construction projects. With the complexity of the industrial plant projects, the industry practitioners need to be able to visualize the construction schedule information to manage the project efficiently. This study suggests methodologies for improving PMIS specialized for industrial plant piping construction projects to estimate the baseline schedule and performance measurement more accurately by developing a framework for the piping construction projects. By using this developed system, the researchers expect that piping construction projects will be more efficiently managed on a real-time basis through measuring progress of piping at each and every state of progress milestone and provide management with opportunities to forecast the level of efforts required to execute the remaining work scope in a timely manner.

Construction practitioners recognise that rework is undesirable due to the detrimental effects. While rework literature has examined rework causation factors in construction projects, the problem continues to plague the industry resulting in poor delivery performance. To better understand this phenomenon and given the scarcity of Malaysian-based rework study, a questionnaire survey involving 130 Malaysian construction practitioners (consultants, contractors and clients) were undertaken to obtain feedback about nature, implications, causes and solutions for rework. Data were analysed using descriptive statistical techniques to prioritise the variables studied. From the analyses, rework is a causal factor for delays and cost overruns, higher wastage and productivity inhibitor. The findings revealed the leading causes of rework are poor quality management, improper planning, lack of communication, design changes and poor subcontractor management. Some practical rework minimisation approaches are also suggested to better manage and prevent rework towards enhanced project performance.

Construction industry is considered to be one of the most important industries in Vietnam's economy. But many construction industry sectors have been experienced chronic problem as cost overrun. Therefore, a conceptual model of factors influencing construction cost was developed to determine the key factors that cause difference between budget cost and actual cost and some solutions are recommended to be applied to achieve the best outcome of cost. The result of analyzing 216 construction projects completed from 2002 to 2007 by companies located in Ho Chi Minh City indicated 6 main factors varying construction cost: project planners, project executives, economics, political, natural environment, fraudulent and lost. The results of multiple linear regression model confirmed the relationship between these above 6 factors and construction cost with the theories are supported at the statistically significant level of 0.05.
