Abstract/Summary
Wildfires in California have increasingly been linked to failures in electrical infrastructure, particularly overhead power transmission, and distribution systems. As wildfire frequency and severity continue to escalate, utility providers, regulatory agencies, and construction professionals are evaluating undergrounding power lines as a long-term mitigation strategy. This research examines the construction management implications of undergrounding power lines compared to conventional overhead systems, focusing on cost, scheduling, constructability, risk allocation, and lifecycle performance. A mixed-methods approach is utilized, incorporating quantitative cost and lifecycle data alongside qualitative analysis of industry reports and case studies. The results indicate that although underground systems require significantly higher upfront construction costs, they provide long-term value through reduced wildfire risk, lower maintenance requirements, and decreased liability exposure. Critically, the implications of widespread undergrounding extend across all sectors of the construction industry; from residential and commercial development to heavy civil infrastructure and industrial facilities; each facing distinct challenges and opportunities as underground utility systems become more prevalent. The study contributes to construction management knowledge by integrating financial, operational, and risk considerations into infrastructure decision-making processes in wildfire-prone regions.
