Time overrun is a major issue in construction projects. Its causes vary, depending upon the nature and size of the project. Developing countries are more susceptible to this problem due to limited resources and lack of managerial skills. This paper focuses on the identification and classification of time overrun factors in public sector projects in Pakistan. Data was collected by the use of a questionnaire given to different professionals in the construction field. Average index (AI) was used to determine each factor’s relative importance. Results indicate that financial difficulties faced by constructor, inadequate planning and scheduling, financial difficulties faced by client, delays in payment by the client, delays in decision making by the client, design mistakes, frequent design changes, material shortage, incompetent sub-constructor assigned by the constructor, poor site management and supervision and inadequate constructor’s experience are the most significant factors of time overrun in public sector construction projects in Pakistan. This study aims to be useful in addressing the issue of time overrun in the construction industry.

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.

Construction project delays caused by contractors and suppliers are the top problems in Thailand's oil and gas industries. Recognizing this importance and their relationships between factors can help reduce the risk of delays in construction projects. Therefore, this study set out to confirm factors and inspect relationships between delay factors of contractors and suppliers. A 16 item questionnaire survey was distributed to 134 managers, engineers, and supervisors in oil and gas platform construction projects in Thailand. A confirmatory factor analysis (CFA) was performed by the use of Amos Version 20 software program. The analysis results showed that delays caused by the contractors and suppliers had high relationships, due to high regression weighs. The delays caused by the contractors included seven factors which included poor site management and supervision (17%), lack of safety rules and regulations (16%), poor communication and coordination with others (15%), poor procurement system management (15%), defective components and mistakes during construction (14%), supplier payments lateness (13%), and poor planning and scheduling (10%). The delays caused by the suppliers included six factors which included the supply of unqualified and unskilled personnel (22%), supply of low efficiency equipment (20%), late delivery of materials and equipment (20%), supply of low quality materials (16%), late supply of workers (16%), and price escalation (5%).


This research investigates the factors, which cause delay in construction projects in Afghanistan. Delay is one of the major challenges during the implementation of the construction projects, and it is the late completion of the activities or works of a project compared to the planned. A large number of construction projects in Afghanistan are facing delay during the implementation. Project delay negatively affects the prestige and dignity of the government organizations and in general, failures and weaknesses of the projects created distance between the people and the government and shows incapacity of the Government in the implementation of the projects all around the country in Afghanistan. Several similar studies from developing countries have been reviewed and a survey has been conducted for data collection from the different public organizations of Afghanistan. The analysis of the collected data points out the significant causes of delay in construction project in Afghanistan as; ineffective planning and scheduling of a project by contractor, delay in progress payments by client, poor site management and supervision of contractors by consultant and client, financial difficulties by contractor, insufficient controlling and monitoring by consultant and client, non-availability of experienced technical staff of contractor, late in reviewing and approving design documents by client, lack of communication and coordination between the parties, delay in delivery of materials to site, inadequate contractor experience, political influences and warlords intervention. Finally, this thesis provides applicable recommendations to minimize or eliminate the causes of delay in construction projects in Afghanistan.

AbstractDelays on construction projects constitute a major source of concern due to its associated cost increases and loss of revenue. The Gulf Cooperation Council (GCC), of which Oman is a member, faces huge delays on their projects. Such delays in the GCC were among factors fingered in the collapse of the UK’s Carillion. Despite cultural similarities, substantial variability exists within the GCC construction sector which requires country-specific studies. The quest to understand delay causes results from the need to curtail wastes and adjust to the new regime of low commodity prices. There is a dearth of studies specific to the governorate of Muscat exploring the causes of delays and this study seeks to fill that gap. A structured survey questionnaire was administered at two independent events organized by the RICS and ICE in Muscat. The top causes of delays ranked using the Relative Importance Index (RII) include variation and changes in design, Poor site management and supervision, ineffective planning and scheduling, unclear and inadequate details in drawing, poor qualification of the contractors and technical staff, delay in material delivery, and shortage of labor. Contractors were found to be most likely to cause delays among the 6 categories of sources.

Purpose Projects often face delays and unnecessary use of time due to various factors and reasons, and hence suffer from unfavourable consequences. The purpose of this paper is to identify the universal delay factors from an intensive literature review, complemented by delay factors in major Norwegian construction projects based on empirical data. Design/methodology/approach The study in which this paper is based includes an intensive literature review, and semi-quantitative open survey questionnaires. This paper addresses frequency and type of delay factors in construction projects, in Norway based on the survey, and worldwide based on the previous studies. Findings From the study, the causes of delays facing the Norwegian construction industry are: poor planning and scheduling; slow/poor decision-making process; internal administrative procedures and bureaucracy within project organisations; resources shortage (human resources, machinery, equipment); poor communication and coordination between parties; slow quality inspection process of the completed work; design changes during construction/change orders; sponsor/owner/client lack of commitment and/or clear demands (goals and objectives); late/slow/incomplete/improper design; office issues; and users’ issues. And the top 10 universal delay factors are: design changes during construction/change orders; delays in payment of contractor(s); poor planning and scheduling; poor site management and supervision; incomplete or improper design; inadequate contractor experience/building methods and approaches; contractor’s financial difficulties; sponsor/owner/client’s financial difficulties; resources shortage (human resources, machinery, equipment); and poor labour productivity and shortage of skills. Research limitations/implications When it comes to the identification of delay factors in major Norwegian projects, the research is based on a sample of 202 respondents from an open survey questionnaire. It should be noted that analysing a large population of respondents that have been asked open questions can be challenging due to the vague findings it might lead to. Also, when it comes to the identification of the universal delay factors, there were different methods used by different authors, within different context. Similar future studies in Norway based on qualitative and quantitative methods will give better verification for the findings. Practical implications This paper has documented the critical delay factors/causes in Norway. The results of this study will help project managers, in Norway and elsewhere, to be aware and know about the potential causes of delay in their construction projects, which will help to identify the possible risks in the early phases of the project. Another practical implication is to make project managers and policy makers conscious that delays are quite universal, making it necessary to identify them as a first step. Social implications The identification of delays factors and causes can permit projects to implement mitigation actions to avoid delays, thus allowing delivering schools, hospitals and other necessary infrastructure on schedule or ahead of schedule to society. Originality/value This paper highlights most (almost all) of the studies in the literature, including to the study done in Norway, concerning the delay factors in construction projects and large construction projects in general. This wide review of relevant literature will save time other academicians from having to conduct similar studies. This study will assist both academic and professional experts providing more insight about the delay causes in large-scale construction projects.

This paper presents a study conducted to identify, assess, rank, and compare the most influencing factors causing schedule delay during construction phase of petrochemical projects in Saudi Arabia. The methodology followed in this research to achieve the main aims is a combination of comprehensive review of the literature and interviewing number of local experts, which have resulted in identifying of 23 factors. Through a web-based questionnaire survey, the identified factors were ranked. Total of 90 completed responses were gathered from 106 received responses. The completed responses gathered from 38 contractors and 52 owners. Of 90 participants, there are 32 project managers, 22 project engineers, 7 construction supervisors and the other 31 having different positions in projects departments The study has found that the most influencing factors causing schedule delay during construction in petrochemical projects in Saudi Arabia are “Poor site management and supervision by contractors”; “Conflict between main contractor and subcontractor”; “poor planning and scheduling of projects by contractor”; “Delay of material or equipment delivery”; and followed by “Delay in Handing Over Construction Site to Contractor”. This paper is original in the sense that the areas of knowledge and practice covered in the identified factors were distributed and not available in one source. The factors are derived from personal interviews with selected project managers, project engineers, construction supervisors and the others from different positions in project department and from the relevant literature.

Purpose The purpose of this paper is to present a systematic review of studies on CPD published between 1985 and 2018. Design/methodology/approach 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. Findings 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. Originality/value 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.

Claims are considered to be one of the most serious disruptive forces to successful project delivery in the construction industry. In a small developing economy like Botswana, it is germane to identify the sources and the frequency of occurrence of claims so that the burden of project cost overrun, a hallmark of the country’s construction industry is substantially reduced. Detailed literature review and preliminary field investigations were used to identify causes of claims related to road construction projects. The study identified six major types of claim and twenty seven causes of claims. Using questionnaire as research instrument, respondents (construction industry major stakeholders i.e. clients, consultants and contractors) were asked to rank the frequency of occurrence of the types and causes of claims in road construction projects on a Likert-type scale. Relative importance index (RII) method was used to analyze the data collected from the questionnaire survey. The analysis was carried out for each group of respondents and on the overall results (all the parties combined). A total of 27 useful responses made up of nine clients, ten consultants and eight contractors) were analyzed. Findings indicated that the clients and consultants specified delay claims followed by extra work claims were the most frequent type of claims in the construction of roads in Botswana. Contractors perceived differing site conditions followed by delay claims as the most frequent type of claims. From the overall response, delay claims were ranked first followed by extra work claims. Acceleration claims were ranked least. The top five most frequent causes of claims based on overall ranking were: variation in quantities, design errors, poor site management and supervision by contractor, ineffective planning and scheduling of project by contractor, and low price of contract due to high competition. Construction industry research in Botswana has never looked into the issue of claims and yet it is one of the hidden sources of construction project failure in the country. It is perceived that hedging against the most adverse causes of claims will stem the tide of incessant cost overrun, litigation and project abandonment on road projects in Botswana.

Construction sites generate a large amount of material wastes and have become a common problem with associated risks in Ethiopia. However, the sources of such wastes are not well recognised. Therefore, the purpose of this research was to analyse the risk factors that contribute to material wastes in building construction projects. To achieve this goal, the factors that cause construction wastes were identified from literature and construction experts via focus group discussions and personal interviews. Following this, the factors were subjected to a questionnaire survey to identify the most critical factors of construction wastes. The questionnaire was distributed purposively to 85 construction experts representing contractors, consultants, and clients and 70 questionnaires were duly received for analysis. The data were analysed with a mean score and ranked to identify the most critical factors generating material wastes at construction sites. According to the results of the study frequent changes made to the design, poor strategies for waste minimisation, improper storage of material, poor site management, poor planning and supervision, and errors of contract document were the most critical factors causing construction wastes.

The purpose of this study was to identify factors that influence project cost overrun within public sector construction projects with specific reference to Gauteng Province of South Africa. The primary data was collected by means of structured questionnaires which were distributed to practicing construction professionals who are engaged in various dimension in public sector construction projects. The secondary data was derived through reviewed literature. Out of 120 questionnaires sent out, 119 were received, which represented 99% response rate. Data received from the questionnaires was analyzed using descriptive statistical procedures. Findings from questionnaire survey revealed that the most dominant factors of cost overruns in public sector project include: variation orders, change in scope of the project, cash flow and financial difficulties faced by contractors, delays in decision making by professional consultants representing the clients, inadequate planning, frequent design changes, lack of coordination between parties, amongst others. The study thus revealed that it is necessary to identify factors that influence construction cost overruns at the start of the project in order to minimize cost overruns and to improve the cost performance on public sector construction projects. This is because of the high level of accountability necessary required for the management of tax payers money.
