Keller successfully completed the ground improvement works using a combination of RIC, DC, DR, and VR techniques, delivering significant cost and programme savings for the client.
Ground improvement was executed as close as 3 metres from existing utilities, demonstrating precise execution and effective risk management. The project was completed on schedule, with zero quality or safety issues and excellent client satisfaction.
The project
The KEZAD Gate Warehouses project is located in ICAD III, Industrial City, Abu Dhabi, UAE. The proposed development covers a total area of 350,000m².
Keller, as a specialist geotechnical contractor, was awarded the works to design and build a ground improvement solution for widely heterogeneous ground conditions.
The challenge
The primary challenge was to create zones where an appropriate solution could be applied to meet the specific foundation types and varying load/settlement criteria, and to mitigate the liquefaction risk. The selection of the right technique also needed a check for nearby underground utilities and services. All this needed to be completed within the challenging time frame.
The solution
Keller adopted the DC/DR techniques to improve larger areas in a shorter time. The Vibro-Replacement technique for stone column installation provides the solution to work closer to areas near underground utilities due to its smaller range of dynamic impact in the horizontal plane.
Shallower compaction requirements were met with the RIC technique. The works were completed on time with a high level of Safety and quality standards acknowledged by the Customer.
“Professional company, following high Safety & Quality standards and very cooperative as a team”.
