This document presents a techno-economic analysis comparing gabion retaining walls to conventional retaining walls. It analyzes rubble masonry gravity walls, RCC cantilever walls, RCC counterfort walls, and gabion walls. Design parameters like height, backfill, foundation, and loads are kept constant. The designs are then compared based on required cross-section and steel. The analysis finds that gabion walls prove more economical due to using locally available materials, which makes construction faster and cheaper compared to other wall types. Key advantages of gabion walls identified are easy drainage, flexibility to tolerate differential settlement, speed of construction, ability to use waste materials, and no hydrostatic pressure buildup.
