The Top-Down Construction Method offers a safe, efficient, and sustainable solution for complex underground and high-rise projects, particularly on geotechnically challenging or sensitive sites. Increasingly applied in Iran for tunnels, metro stations, and building, it requires integrated expertise across multiple engineering domains. Despite its technical depth, few comprehensive resources exist—this book fills that gap, combining theoretical foundations with practical guidance for engineers, consultants, and contractors.
