Pentominium ... to feature the deepest piles in the UAE.

Trident International Holdings (TIH) has awarded the enabling works contract for its 516-m-tall Pentominium to global major Swissboring Overseas Corporation (Swissboring).

The contract has been awarded based on Swissboring’s vast international and regional experience in executing some of the most challenging projects, according to the developer.
Commenting on the contract, Wazir Daredia, executive director and CEO, TIH, said: “At 516 m, the Pentominium is definitely one of the most challenging real estate projects undertaken in the world.
“Furthermore, its piling and shoring contract gains in significance and complexity as it includes work on laying Dubai’s deepest piles, at an estimated depth of 65 m to support approximately 3,500 sq m of footprint area. The most important element of any project is its foundation and given its challenging backdrop, it was imperative that we appoint the absolute best.
“Swissboring with its vast experience of over 7,500 ground engineering projects which includes piling, shoring, soil investigations, underpinning and grouting projects under its belt in the GCC alone, was a unanimous choice for the piling and shoring contract of the Pentominium,” Daredia added.
As per the arrangement, Swissboring will be responsible for shoring and temporary work (retaining walls), excavation and earth works, foundation piling work (supply and installation of approximately 250 piles) for the tower, pile testing and certification, dewatering work, site establishment and final clean-up.
The structural and geotechnical design for the Pentominium project is being carried out by international advisory and design consultancy Hyder Consulting, which boasts over 45 years of Middle East presence. Hyder Consulting will apply the extensive experience it has gained in the region’s high-rise projects to optimise the design.
For the foundation of the Pentominium, a full 3-D Finite Element (FE) model will be developed, incorporating detailed site investigation information, including specialist testing and preliminary pile test data. Hyder Consulting will carry out an assessment of the pile-soil-raft interaction within the FE model resulting in a design that requires minimal pile lengths.
Additionally, the range of pile loads from the FE model provides a good base to assess the possibility of pile-soil degradation, due to cyclic loading, which is a risk posed by the weakly cemented calcareous deposits commonly found in this area. Further to the appointment of Swissboring for the enabling works assignment, Hyder Consulting will also play a crucial role in the piling and shoring phase of the project. 
Strategically located at the exclusive Dubai Marina, the Pentominium will rise up to 120 floors. An individual unit will take up a complete floor of the tower providing more than  6,500 sq ft of private world class luxury. Each floor will have its own exclusive private foyer with each unit equipped with state-of-the-art biometric access control. Pentominium boasts entire floors which are uniquely suspended in mid-air, creating an illusion of floating penthouses in the sky.
