Wet Works & Land Reclamation - What Could Go Wrong?
โ
On March 18, 2025, the Wet Works & Land Reclamation Seminar by The Singapore College Of Insurance brought together industry experts, insurance professionals discussing the complex risks, challenges, and mitigation strategies shaping marine and coastal construction. As land reclamation continues to drive urban expansion, addressing ground stability, material shortages, environmental concerns, and regulatory challenges is more important than ever.

Singapore has expanded its land area by over 25% through reclamation, with similar large-scale projects underway in Dubai, Malaysia, Indonesia, and Macau. However, rising material costs, environmental regulations, and logistical challenges call for more sustainable and resilient solutions

Ground instability remains a major risk, as placing heavy fill on soft marine clay can lead to rotational slope failures, lateral sliding, and excessive settlement. The Kansai International Airport case highlighted how miscalculations in settlement projections resulted in uneven subsidence, structural damage, and costly reinforcements. Additionally, sand shortages, export bans, and international disputes are forcing engineers to explore alternative materials like dredged sediment and engineered infill solutions.

To enhance long-term stability, projects are using vacuum preloading, vertical drains, and staged backfilling. Alternative reclamation methods like polder development, requiring less sand and active water pumping, are gaining traction, as seen in Tuas Mega Port. Proactive risk management, including early regulatory engagement, stakeholder consultation, and well-structured contracts, is essential for avoiding legal and financial risks.

Sustainable solutions and technology-driven planning will define the future of land reclamation. The reuse of dredged materials, AI-powered risk modeling, and digital twin simulations is improving project predictability, cost efficiency, and environmental sustainability. Large-scale projects like Singaporeโs Long Island (~800 hectares) and Manila Bay reclamation (~5,000 hectares) highlight continued investment in reclamation, despite increasing regulatory scrutiny and environmental challenges.
