Abstract

Purpose - As a result of the increasing challenges of time overrun, several companies regularly set up delay assessment procedures for performance improvement and profit maximization. In the construction industry, projects are enormously complicated and involve significant budgets, and therefore optimizing project performance through the root cause analysis should be imperative for every project manager. Typically issues of delays in projects are generally discussed and problematized separately, yet a comprehensive framework for systematic analysis and grouping of delays is rarely contended. In this article, the 4P concept (Project Related, Practices, Participants and Procurement) has been introduced for identifying, analyzing and classifying delays in the internal environment of the project development process. Design/Method/Approach - The 4P conceptual framework was validated through the synthesis of the existing literature. Findings – Interestingly despite the increasing concerns about delays in the construction industry, most research on delays are project and/or country specific, thus no consensus about the sources of delays. The application of the proposed concept as a theoretical framework would provide an understanding of the available delay sources, their risks and use for project delay assessment and classification. Research limitations/implications – This study grouped delays based on shared characteristics and four main sources were identified and analyzed. There may be other sources or factors, yet would be dependent or aspect of the 4P. Practical Implications – Informs project teams to reduce delays in the construction industry. Originality/value – Application of risk assessment tool to conceptualized delays in the internal project environment.

Conclusion

In this paper, the 4P concept was validated through literature review for the identification, categorization, and analysis of delay sources in the internal construction project environment. First, the review indicated that the body of literature related delays assessment lacks cohesion and integrated focus, and the need to systematically assess, locate and develop comprehensive delay assessment framework within the internal project environment is not adequately addressed. To validate the concept, the study identified the sources of the delays and then further identified the individual risks associated with the sources. First, data from medium to large projects was gathered from peer-reviewed journals, conferences, books and other databases within the civil engineering, construction management, project management, technology management, architectural management, built environment, etc. To ensure the comprehensiveness of the concept, this study examined the references made by the authors to determine if those articles have relevant contributions or impacts. Finally, the study identified the sources of the delays and then further identified the individual risks associated with the sources. The risks or delay factors were then categorized under main sources based on shared characteristics.
