Concrete Coring for Deep Soil Mixing (DSM) Works – VVIP Airport Development: Airside Facilities, Physical Construction Package

The Concrete Coring for Deep Soil Mixing (DSM) Works at the VVIP Airport Development – Airside Facilities: Physical Construction Package were conducted to verify the quality and performance of ground improvement works using the Deep Soil Mixing method for airside infrastructure. The scope of work included coring of DSM columns, collection of treated-soil samples, evaluation of DSM material quality and strength, and interpretation of test results to support quality control of the ground improvement works. Key challenges included verifying DSM performance against design requirements, soft ground conditions within the airport area, and the need to ensure adequate soil and pavement stability for airside operations. The technical approach involved controlled coring and material testing, assessment of the quality and performance of the treated ground, and development of technical recommendations to support the safety, stability, and reliability of the airport infrastructure.
