Vertical Transportation Solution

Dunbar & Boardman supported the design and delivery of a comprehensive vertical transportation strategy incorporating:

• Passenger Elevators
• Service Elevators
• Firefighting Elevators
• Hotel Lift Systems
• Residential Lift Systems

The final installation comprised:

26 Elevators

Serving hotel, residential, service and operational functions across both towers.

The project required several non-standard solutions, including the integration of side machine-room arrangements for high-speed service lifts due to structural and architectural constraints within the building design.

Façade Access & BMU Strategy

The architectural form of the towers created significant façade access challenges, including:

• Sloping roof profiles
• Curved façades
• Projecting balconies
• Recessed glazing zones
• Restricted roof space

Dunbar & Boardman developed and evaluated multiple façade access strategies before supporting the implementation of a static Building Maintenance Unit (BMU) solution integrated with additional maintenance access systems.

The final solution incorporated:

• Permanently Installed BMUs
• Rope Access Provisions
• Monorail Systems
• Maintenance Access Equipment
• Cleaning Cycle Optimisation

The strategy ensured safe and efficient access to all façade areas while maintaining architectural integrity and operational practicality.

Key Project Challenges

Vertical Transportation

• Integration of high-speed lifts within constrained structural arrangements
• Side machine-room configurations
• Coordination between hotel and residential operations

Façade Access

• Sloping tower crowns
• Curved building geometry
• Balcony projections
• BMU parking and storage constraints
• Complex maintenance access requirements

Through detailed design reviews and close coordination with the wider project team, these challenges were successfully resolved.
