Geotechnical risk management in soft soil construction projects is critical due to the challenges posed by weak ground conditions. This study presents three case studies that demonstrate different approaches to addressing these challenges. In Case 1, at the Hospital Tengku Ampuan Rahimah Integration Quarters in Klang, improved design measures and enhanced preconstruction practices were applied to reduce settlement risks and ensure structural stability. In Case 2, at the Core Facilities Building of Polytechnic Kota Kinabalu, both immediate and long-term countermeasures were implemented, where short-term monitoring recorded differential settlement of up to 130 mm and long-term predictions ranged between 243–384 mm over 9–14 years. In Case 3, at Batu Kawan, dynamic consolidation combined with prefabricated vertical drains accelerated ground improvement, allowing the treated soil to achieve the required bearing capacity within 126 days. A comparative assessment of the three projects highlights the importance of proactive design, monitoring, and treatment in managing geotechnical risks, providing practical guidance for foundation construction on soft soils.
