Issue Date: | 2024 | Publisher: | [Kalhat, Lebanon] : [University of Balamand], 2024 | Abstract: | The construction landscape is incredibly vulnerable to risks that can affect the successful implementation of projects. Particularly, the preconstruction stage sets the foundation for the project, with the design process accounting for more than 75% of the overall project cost. As such, it is imperative to effectively and efficiently assess, manage, and mitigate risks during this stage to ensure the timely completion of the project. In this paper, a Lebanese architectural firm based in Beirut, Tony Haddad + Partners - THP Architect, was used as a case study in order to investigate the major risk factors that lead to time overruns of international architectural design projects. Intrinsically, eighteen risk factors have been identified and categorized as: (1) external risks, (2) design process risks, and (3) client-related risks. The likelihood, impact, and weight of each risk on the schedule of projects was assessed based on the analysis of historical and past data from the firm. This was complemented by professional opinion and brainstorming sessions. The time risk index (TRI) for each factor, which provides a systematic indication of its impact on project timeframes, was determined by applying analytical methods, including regression analysis and principles of the analytical hierarchy process (AHP). Results showed that the main factors for time overruns of design projects are essentially client-related, including excessive modifications in the scope of work and delayed approvals. Furthermore, poor communication among project parties, increasing size and complexity of designs, as well as external and economic variables such as the COVID-19 pandemic and inflation further cause projet delays and impede its implementation. The risk “early contract termination (ECT)” could not be quantified in spite of its importance and frequency of occurrence, thus needing additional future research because of its special characteristics and measurement difficulty. Finally, a customized time risk analysis model was developed with the aim to prioritize risks, increase workflow efficiency, and improve client involvement in the project. Essentially, this model focuses on the development of effective risk stragegies for architectural design projects by providing practical insights for preventing project delays and building resilience |
