Marina Bay Sands IR2 – Foundation & Site Investigation Works

This project highlights Geolutions’ extensive involvement in the Marina Bay Sands IR2 development, where our team delivered a full suite of accredited foundation testing, site investigation, and monitoring solutions. Using advanced Hanjin drilling rigs imported from South Korea, we executed bi‑directional static load tests on 9,000 kN barrette piles, foundation base grouting, and a range of integrity and dynamic tests including PDA, PIT, Sonic Logging, and Sonic Coring. Our scope also covered pile instrumentation, CAPWAP analysis, and comprehensive laboratory support, ensuring reliable data and performance validation for one of Singapore’s most iconic infrastructure projects.

ABOUT THE PROJECT

Geolutions is proud to support the development of Marina Bay Sands’ new ultra-luxury resort expansion, IR2, as a sub-contractor to LT Sambo and consultant ARUP Singapore. With a projected cost of US$8 billion, this landmark project will enhance the existing resort and redefine Singapore’s skyline. IR2 will feature a 570-suite luxury hotel with a signature rooftop experience, alongside destination dining, nightlife, and public attractions. Key facilities include 200,000 square feet of premium MICE space and a 15,000-seat arena set to become Asia’s leading live entertainment venue.

Construction is scheduled to begin in June 2025 and complete by June 2030, with the official opening expected in January 2031, subject to government approval. Geolutions brings proven expertise in comprehensive geotechnical specialist works to this prestigious development.

WHAT WE DID

Geolutions conducted the Site Investigation (SI) works using our Hanjin drilling rigs imported from South Korea. Based on our SI report, we utilized the factual soil data to develop the Ultimate Load Test proposal submitted to Arup, aiming to validate the initial design parameters of the project's overall foundation scheme.

The proposed testing method was a bi-directional static load test for a 90,000 kN test barrette pile. Geolutions was responsible for the complete design, assembly, installation, and testing of the bi-directional jack system, ensuring continuous supervision throughout the process to maintain high-quality standards.

Additionally, we provided support for the Foundation Base Grouting works, enhancing quality assurance by improving the toe contact between the foundation and the competent stratum. To further verify the integrity of the working bored piles and diaphragm walls, a comprehensive series of foundation tests were conducted, including PDA (Pile Driving Analyzer), PIT (Pile Integrity Test), Sonic Logging, and Sonic Coring.

All tests were conducted exclusively by Geolutions' personnel, utilizing our own machinery, equipment, and tools. The geotechnical specialist works were carried out in full compliance with the relevant reference standards under our SAC-SINGLAS accredited Laboratories and Inspection Bodies Scheme.
