The Agile transformation of 132/11 kV Capital Substation Projects has significantly improved efficiency, cost-effectiveness, and sustainability in infrastructure development. By leveraging Lean and Agile methodologies, including Scrum frameworks, process streamlining, and extensive workforce training, project delivery timelines were reduced by 30%, cutting construction duration from 30 to 21 months. This transformation resulted in AED 1.8M in cost savings per substation, amounting to AED 27M annually, alongside an 84% improvement in first-time drawing approvals. Additionally, the integration of precast construction methods reduced 3,165 tons of CO₂ emissions across 15 substations, reinforcing Agile’s role in sustainable project management. The benchmarking of these innovations against other government authority CFR process further highlights Agile’s scalability and industry relevance. These findings demonstrate that Agile is not only a project management methodology but a transformative approach that enhances speed, cost-efficiency, governance, and sustainability in capital infrastructure projects.
