A well-functioning construction industry is a prerequisite for the development process to take place. In this regard, the aim of this study is to identify the most frequent, severe, and important causes of schedule delays affecting public constructions projects in Burkina Faso to enhance the managerial capability of project managers. This research was conducted by questionnaire survey to solicit the causes of schedule delays from 140 Burkinabe experts (clients, contractors, and consultants). After analyzing their frequency, severity, and importance index using a quantitative statistical method, the top five most important delay factors were ranked as follows: financial capability of the contractor, financial difficulties of the owner, equipment availability of the contractor, slow payments for completed work, and poor subcontractor performance by the contractor. A comparison of the causes of schedule delays in 11 countries to validate the results of the study showed that financial capability of th...

Empirical Study of Factors Influencing Schedule Delays of Public Construction Projects in Burkina Faso

The purpose of this paper is to present a systematic review of studies on CPD published between 1985 and 2018.,Before identifying common CPD, research trends were examined in terms of the number of publications in selected journals, as well as the contributions made by countries, institutions and researchers.,The findings reveal that researchers from developing countries have contributed the most to identifying the causes of CPD. A total of 149 causes of CPD were identified in a thorough review of 97 selected studies. Weather/climate conditions, poor communication, lack of coordination and conflicts between stakeholders, ineffective or improper planning, material shortages, financial problems, payment delays, equipment/plant shortage, lack of experience/qualification/competence among project stakeholders, labour shortages and poor site management were identified as the ten most common CPDs.,Being the first study of its type, this study provides insight into the research output related to this area and identifies a common set of CPDs, which may provide a better understanding of the key areas requiring attention where steps should be taken to minimise or control factors causing delays in construction projects.

Causes of delays on construction projects: a comprehensive list

Collaborative model: Managing design changes with reusable project experiences through project learning and effective communication

This study uncovered inhibiting factors to cost performance in large construction projects of Malaysia. Questionnaire survey was conducted among clients and consultants involved in large construction projects. In the questionnaire, a total of 35 inhibiting factors grouped in 7 categories were presented to the respondents for rating significant level of each factor. A total of 300 questionnaire forms were distributed. Only 144 completed sets were received and analysed using advanced multivariate statistical software of Structural Equation Modelling (SmartPLS v2). The analysis involved three iteration processes where several of the factors were deleted in order to make the model acceptable. The result of the analysis found that R(2) value of the model is 0.422 which indicates that the developed model has a substantial impact on cost performance. Based on the final form of the model, contractor's site management category is the most prominent in exhibiting effect on cost performance of large construction projects. This finding is validated using advanced techniques of power analysis. This vigorous multivariate analysis has explicitly found the significant category which consists of several causative factors to poor cost performance in large construction projects. This will benefit all parties involved in construction projects for controlling cost overrun.

SEM-PLS Analysis of Inhibiting Factors of Cost Performance for Large Construction Projects in Malaysia: Perspective of Clients and Consultants

Purpose




The purpose of this paper is twofold: first, to develop theoretical underpinnings using TCE, and second, to run the analysis using an advanced tool such as structural equation modeling (SEM).




Design/methodology/approach




This study was conducted in the construction industry in Tanzania. A questionnaire-based survey method was used. A total of 308 respondents participated in the study. The relationships between the cause and effect factors were analyzed using SEM.




Findings




The important findings are as follows:cost overrun can be explained by consultant-related and material-related factors; disputes can be explained by cost overrun; arbitration can be explained by consultant-related, cost overrun, and dispute factors; litigation can be explained by client-related, disputes, and arbitration factors; and abandonment can be explained by consultant-related, external-related, disputes, arbitration, and litigation factors.




Originality/value




The main contributions of this study are theoretical development and comprehensive analyses of “cause” and “effect” factors of delays in the construction industry.

Analysis of delays in Tanzanian construction industry

There is great concern in Uganda about delays and cost overruns in public sector construction projects because such projects are implemented using taxpayers' money. At the national and international levels, there is considerable debate regarding how to minimise project delays and cost overruns. The main objective of this study was to investigate the causes of construction project delays and cost overruns in Uganda's public sector. Specifically, this study was conducted to identify the causes of delays and overruns and to rank them according to their frequency, severity and importance. The Civil Aviation Authority (CAA) was selected as a case study as a means of validating the results of the survey. Frequency index, severity index and importance index values were computed and all 20 factors involved were ranked. The five most important causes of delays in construction projects were found to be the following: changes to the scope of work, delayed payments, poor monitoring and control, the high cost of capital and political insecurity and instability. The relationship between the factors that cause delays and those that cause cost overruns was found to be moderate. Recommendations are made for improved project management, a change from the traditional contract type to the design-build type and improved cash flow on the part of the client to reduce payment delays. The results of this research should help construction practitioners, policy makers and researchers in the field of construction management.
