GeoStruXer faced the challenge of rehabilitating a warehouse in Jazan, Saudi Arabia, suffering 170 mm of settlement due to salt dome creep in an active seismic zone, requiring continuous operation. Using Bentley PLAXIS 3D and RAM Concept, GeoStruXer created a combined micropiled post-tensioned (PT) raft system. The digital twin was calibrated with AI and InSAR satellite data to accurately model 20-year creep and seismic risk, a feat impossible with traditional tools. This resulted in a 70% reduction in micropiles (from 2,700 to 779), saving 1,200 tonnes of steel and cutting embodied carbon by 44% (over 2,000 tonnes of CO2. The project reduced construction costs by 2.1 million USD and shortened the design cycle by 35%. This blueprint for sustainable retrofit in challenging ground conditions directly supports Climate Action and protects Land and Water Resources by minimizing disruption to the sensitive Sabkha terrain.
