Quantitative Analysis of Project Delays and Mitigation Strategies at an Engineering Organisation in the UAE

Abstract

Complex operational environments, tight deadlines, fast-tracked projects and high demands from multiple stakeholders (both internal and external) present significant challenges in the engineering sector, particularly Mechanical, Electrical and Plumbing (MEP) and energy retrofit fields in the UAE. These changes often lead to project delays, which result in increased budgets and stakeholder or customer dissatisfaction. Energy efficiency and sustainability are two of the primary motivators for the UAE construction and engineering industry, yet both are negatively affected by project delays. This research provides a quantitative analysis of project delays based on three comprehensive real-world case studies of MEP and energy retrofit projects executed by an engineering organisation in the UAE. A retrospective delay analysis of As-Built vs As-Planned schedules was applied to quantify delays, identify and categorise primary and secondary causes, and measure their time impact and critical contributions. Supporting tools such as Root Cause Analysis, Gantt Charts, Risk Assessment and Mitigation Strategies were employed. The findings highlight client-related delays as the major contributors, followed by insufficiencies in internal processes, procurement and supply chain management. This dissertation offers valuable insights into proactive delay management and proposes actionable strategies tailored to the unique characteristics of MEP and energy projects executed within an operational shopping mall facility in Sharjah, where numerous external and internal factors critically influence project performance. The study also outlines future recommendations and research limitations to enhance adaptability to evolving project and market requirements in the UAE.
