In the Business Bay area of Dubai, Bayz 101 is a landmark residential tower development by Danube Properties. The project consists of over ninety five floors of luxury residential apartments and incorporates a long list of amenities for residents to enjoy – including retail outlets, swimming pools, a gym, basketball and tennis courts, a business centre, a library and a sky garden at level ninety one with spectacular panoramic views over the Dubai skyline.

BG&E’s role included

• Full structural concept and schematic design and documentation.
• Structural oversight and review for the detailed design.
• Support through the authority approval process.

The structure consists of six levels of underground basement parking with sixteen levels of additional over ground podium parking, on top of which the residential tower rises a further seventy five stories.

The building is supported at its foundation on a reinforced concrete raft slab, up to 6.5 metres thick, that in turn is supported by concrete piles of 1.5 metres to 1.8 metres in diameter.

Tower columns make use of composite action – using high-strength concrete with embedded structural steel sections to deal with the enormous vertical building loads.

Typical above-ground podium and tower floors are designed as post-tensioned concrete flat plates to simplify the concrete profile and decrease floor-to-floor construction cycle times for the builder, ensuring an efficient construction programme is achieved. Post-tensioned slabs also allow the thickness of the floors to be minimised, reducing overall building weight and the sizes of supporting structural elements such as walls, columns, raft slabs, and piles.

Lateral loads are resisted by the central reinforced concrete core walls in combination with concrete outrigger walls and belt walls at mechanical floors. These occur at five separate locations throughout the tower height and ensure sufficient stiffness to resist lateral wind and seismic loads and to ensure building movement remains within acceptable levels.

The top of the tower incorporates an indoor and outdoor sky garden as well as an open 15 metre high internal atrium space that allows a panoramic view of Dubai’s skyline. Structural steel framing is provided to minimise structural size and maximise the architectural impact of this incredible building feature.
