Abstract

The present paper presents the major causes of delays in the construction industry in Lebanon and the relative importance of these postponements. A survey of a randomly selected sample of 11 owners, 15 contractors and 10 architectural/engineering (A/E) firms from Lebanon was undertaken. The survey included 64 causes of delay, grouped into 10 major groups, in which the participants were asked to indicate their level of importance of each delay. The level of importance of the causes and the groups were measured and ranked by the importance index for owners, contractors and A/E firms. It was found that all three parties generally agreed on the ranking of the major categories of delay factors. Owners had more concerns with regard to financial issues, while contractors ranked contractual relationships highest, and finally, A/E firms ranked project management highest.

Abstract

Purpose

Successful implementation of construction projects is one of the crucial factors for the economic development of every country. The main part of the countries’ capital is allocated to civil and infrastructure projects annually, most of which are accomplished with delay. Construction projects are often criticized for overrunning time and budgets. Analyzing the factors causing delay is essential for omitting them and timely implementation of these projects. Due to the importance of oil projects, this study aims to investigate and analyze the factors causing a delay in Iran’s oil construction projects.

Design/methodology/approach

In this research, after a broad literature review, using the fuzzy Delphi method, a total of 75 delay factors were identified under 11 major categories of owner, contractor, consultant, equipment, labor, materials, design, contract and contractual relations, laws and regulations, environmental factors, and managerial factors. Then, by using the best-worst method, the factors were prioritized.

Findings

The results showed that sanction, governmental management systems, weak project management by the contractor, technical and managerial weaknesses of the consultant, financial problems and delay in payment by the owner, low efficiency of the equipment, low productivity of the workforce, changes in laws and regulations, inappropriate organizational structure linking to the project, changes in the design, and changes in the price of materials are the most crucial factors causing a delay in Iran’s oil construction projects.

Research limitations/implications

These findings are expected to have significant contributions to Iran’s oil construction industry in controlling the time overruns in construction contracts.

Originality/value

The main contribution of this study is to develop a comprehensive framework in which, causes of delay in Iran’s oil construction projects are addressed and prioritized.

Abstract

Purpose

The purpose of this paper is to investigate the main causes of delay in public construction projects. This is motivated by feedback from public construction experts concerning substantive delays during the last decade. The study thus seeks to help decision makers in Jordan and elsewhere identify problems and develop mitigating strategies.

Design/methodology/approach

Causes of delay were identified from previous related studies and then augmented after consultation with experts. This resulted in 56 delay factors classified into eight groups. The sampling frame for the study was defined in terms of public construction projects (mostly related to roads) owned by the Ministry of Public Works and Housing in Jordan. A survey was conducted with engineers working as representatives of the owner, contractors or consultants to elicit and evaluate the importance of the 56 delay factors.

Findings

Overall, 113 completed questionnaire responses were returned and analyzed to rank the causes of delay using the relative importance index method. Owners and consultants showed more interest in factors related to themselves, while contractors showed highest interest in an external factor related to the owner of services. Four recommendations are put forward for decision makers to mitigate against delays.

Originality/value

This research investigates a relatively large number of delay factors compared to other studies and these are categorized into groups to facilitate thematic understanding. Further, compared to previous related research, this research fills a gap by exploring the opinions of different contract parties.

Abstract

Purpose

Construction delays are a common problem in the Egyptian construction industry. Frequent delays in a project can lead to disputes and litigation. This paper aims to study and analyze the causes of construction delays.

Design/methodology/approach

This research identifies delay causes in residential projects in Egypt and analyzes these causes with the relative importance index method. The feedback of construction experts was obtained through interviews. Subsequently, a questionnaire survey was prepared. Fifty-six different delay causes were identified and categorized into eight categories based on a literature review and interviews with 36 experts from the construction industry who represent owners, consultants and contractors.

Findings

According to the highest values of the relative importance index, the top ten delay causes of residential projects in Egypt are determined. Statistical analysis is carried out using the analysis of variance method to test delay causes obtained from the survey, which revealed a good correlation between residential projects parties with respect to most of the delay causes. A fuzzy logic model using MATLAB is developed for determining the probability of delay of residential projects, and the model was tested in a real case study and was found to be satisfactory.

Originality/value

Delay causes in residential projects in Egypt were identified, and these causes were analyzed using the relative importance index method and fuzzy logic.

Abstract

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.

The purpose of this paper is to perform a quantitative analysis of the literature in order to determine the main causes of delay in construction projects.

Abstract

Purpose

The purpose of this paper is to perform a quantitative analysis of the literature in order to determine the main causes of delay in construction projects.

Design/methodology/approach

A set of 47 articles from the literature were analyzed, yielding 1,057 different causes of delay. In order to analyze and compare the main causes of delay, their degree of impact was studied statistically. Next, a mention count method was used to determine the primary causes of construction project delays and through the use of Pareto diagrams, the main causes of delays in construction projects were determined.

Findings

It was determined that the three main causes of construction project delay are problems that occur during execution, administrative problems and labor conflicts; together they account for almost 80 percent of the causes found in the literature. Moreover, it was deduced that problems during execution are based on unpredictable events, while administrative problems are rooted in poor cash flow management. In addition, seven sub-groups of delay causes were identified as being major due to the number of mentions detected. These were “Changes during construction,” “Poor construction management,” “Construction errors,” “Economic/Financial,” “Conflict/Relationship” and “Lack of experience.”

Practical implications

This study provides a unique classification method, which was successfully validated, for the causes of construction project delay. Thanks to the classification, designers may use this information as a starting point for designing future construction projects, thereby minimizing the appearance of unforeseen events during construction. Moreover, the results of this study will help project managers be aware of the possible causes of delay that may affect their construction projects. This understanding can help them identify potential risks in the initial phases of the project and allow decisions to be made early before problems arise or the consequences of the deviations become irreparable. The results can also serve as input for the development of future management improvement methodologies that are aimed at reducing costs and ensuring that deadlines are met.

Social implications

Identifying the factors and causes of the delays will allow mitigation actions to be taken in order to avoid delays, which will ultimately allow homes, schools, hospitals and other necessary infrastructure to be delivered on time or even before the planned date.

Originality/value

This study provides a unique classification method that was successfully validated. Thanks to the classification, designers may use this information as a starting point for designing future construction projects, thereby minimizing unforeseen events during construction.

Abstract

Purpose

The purpose of this paper is to reveal the main causes of delays in the projects are from the client (relative importance index (RII)=0.716), labor and equipment (RII=0.701) and contractor (RII=0.698). Hence determining the contractual responsibility of delay is the most likely source of dispute in construction projects and many techniques have been used in the courts to demonstrate the criticalities of a delay event on the project schedule. Therefore, authors try to investigate all process-based techniques of delay claims and evaluated and conformed them with principles by Society of Construction Law (SCL) protocol and Association for the Advancement of Cost Engineering International (AACEI) in order to choose the best techniques based on the specific circumstances of each project.

Design/methodology/approach

This section is divided into two distinct parts: refers to the methods used to assess the perceptions of clients, consultants, and contractors on the relative importance of causes of delay in construction industry; and refers to advantages and disadvantages of various techniques used to analyze delays and their conform with SCL protocol. A questionnaire was developed to assess the perceptions of clients, consultants, and contractors on the relative importance of causes of delay in Iranian construction industry. The respondents were asked to indicate their response category on 78 well-recognized construction delay factors identified by authors.

Findings

In total, 78 causes of delay were identified through research. The identified causes are combined into seven groups. The field survey included 58 contractors, 55 consultants, and 62 client. Data collected were analyzed by RII and Statistical Package for Social Sciences (SPSS). The authors identified main causes of delay and ten most important causes, according to Table AII, from the perspective of three major groups of participants (clients, consultants and contractors). The ranking of categories of causes of delay, according to Table I, were: client-related causes (RII=0.716); labor and equipment category causes (RII=0.701); contractor-related causes (RII=0.698); material-related causes (RII=0.690); design-related causes (RII=0.666); external causes (RII=0.662); and consultant-related causes (RII=0.662). But according to the discussions and given that determining the contractual responsibility of delay is the most likely source of dispute in construction industry and many techniques have been used in the courts to demonstrate the criticalities of a delay event on the project schedule.

Originality/value

All process-based techniques of delay analysis have been present in this paper and categorized in 11 groups. In order to understand the advantages and disadvantages of them by clients, contractor and consultant, a thorough review conducted to reveal the nature of techniques. In the next step, given that selecting the most appropriate technique based on constraints and specific conditions of each project is one of the most important steps to carry out a successful delay analysis. The authors conformed, all process-based techniques of delay analysis, by SCL protocol and AACEI principles. Finally, the result of this match was brought in order to choose the best technique based on the specific circumstances of each project.

Abstract

Purpose

Construction project delays are described as a universal problem, which has led to many empirical studies. However, most of these studies were based on the rankings by respondents, and they were rarely verified. Therefore, the purpose of this paper is to explore professional perspectives on the causes of delay in the construction industry, where there has been little explicit consideration on this subject in recent decades.

Design/methodology/approach

A critical literature review and a qualitative approach was considered for a deeper and fresh understanding of the causes of delays, rather than recycling the existing themes and the risk of a statistically biased approach. A total of 41 interviews were undertaken which included the London Olympic 2012 project team.

Findings

In all, 32 themes were identified, which were categorised into 15 categories of causes of delay in the construction projects. Almost two-thirds of the main themes are not ranked top 15 causes of delay. These include knowledge and competence shortage, poor commercial decisions, unnecessary health and safety restrictions, poor risk management and poor space and logistics management.

Research limitations/implications

Due to the qualitative nature of the study, the findings might not be considered as representative.

Practical implications

The findings provide consideration of the causes of delay in the construction industry as seen by practitioners, which should provide guidance to enhance performance.

Originality/value

The study contributes to the better understanding of the causes of delays by using qualitative research strategy which is limited in the construction management literature. This study is an empirical investigation into the causes of delay in the twenty-first century and it represents an important edition to the body of knowledge within the subject area.

Abstract

Purpose

Project delay is becoming a problem in the Sultanate of Oman as evidenced by many delayed projects across the country. The purpose of this study is to examine causes and effects of delays in megaprojects in the Sultanate of Oman with recommendations to mitigate same.

Design/methodology/approach

A systematic review of literature identifies through main stakeholders the numerous causes, impacts and methods of mitigating delay from previous studies. A questionnaire survey on Oman was carried out to sample opinions from the practitioners; 53 questionnaires were received and analysed using the relative importance index (RII) method.

Findings

The five most frequent causes of delay in the Sultanate of Oman, in rank order, are: selection of the lowest bid, instead of best bid for the client (RII: 0.698); the financial condition of the main contractor (RII: 0.664); delay in decision-making by the client (RII: 0.656); and poor construction planning by the main contractor (RII: 0.649). Also, the findings indicate that extra cost (RII: 0.754) and project time overrun (RII: 0.724) are the most significant effects of the delay in the Oman megaprojects. The use of experienced contractors and consultant (RII 0.675), efficient construction planning by the main contractor and effective site management and supervision (RII: 0.667) are essential mitigation methods of construction delay in Oman megaprojects.

Originality/value

The study recommends three-part novel solutions to mitigate delay in the Oman construction industry.

The purpose of this paper is to investigate the causes of road construction delays in Ghana and identify appropriate mitigation measures.

Abstract

Purpose

The purpose of this paper is to investigate the causes of road construction delays in Ghana and identify appropriate mitigation measures.

Design/methodology/approach

The initial approach involved an empirical analysis of 48 road projects to quantify the extent of time. This was followed by a survey of the perception of road agency and donor partner officials of the critical causes of road project delays.

Findings

About 70 per cent of road projects experience delays and 52 per cent experience cost overruns. The average time overrun and cost overruns of road projects in Ghana was 17 months and US$1.15m (or 22.5 per cent), respectively. The five most critical causes of road construction delays were delay in finance and payment of completed work by owner (client-related); inadequate contractor experience (contractor-related); changes in scope by the owner during construction (client-related); delay to furnish and deliver the site to the contractor (client-related); and inflexible funding allocation for project items (donor-related).

Research limitations/implications

The most critical constraint of this study is the fact that findings are based on only the views of industry professional experts. It may be assumed that despite using broadly used terminology to refer to the causes of project delays, the interpretations by respondents may have differed from those intended. Further research could look at the correlation between time overrun and cost overrun using principle component analysis.

Practical implications

The identified delay factors are not unique to the road sector. From both academic and practical perspectives, the results emphasizes on the need for a holistic and integrated risk management model for the entire construction industry in Ghana.

Originality/value

The paper examined the causes of road project delays in the Ghanaian context and recommended remedial measures.
