Lime Street Tower Block – BMU Access Door

With a challenging set of dimensions to work with brought on by the particularly dramatic design of 52 Lime Street’s roof, a brand new approach was required to design and deliver the optimal arrangement of multiple integrated hydraulic doors.

The challenge

In the heart of London among some of the city’s most recognisable buildings sits 52 Lime Street, known colloquially as ‘The Scalpel’. The distinctive architecture with an offset main core and asymmetric facets give the building a truly unique look.

The strikingly shaped exterior demanded a bespoke solution to deploy access equipment from the top of the building. This solution needs to work within the unorthodox dimensions, withstand the force of the prevailing winds, and provide decades of safe and reliable operation.

The solution

To accommodate The Scalpel’s unique dimensions and features while delivering the necessary functionality and safety, a truly innovative approach to engineering design was required. The result is a multi-disciplinary marriage of machinery, engineering, control and moving structures.

To achieve this, the solution that SCX Special Projects designed, built, and installed went through a rigorous optioneering process where numerous, contrasting designs were analysed before arriving at the optimal arrangement of multiple, integrated hydraulic doors.

Extensive concept analysis

  • SCX undertook an array of technical feasibility studies on several proposed concepts to identify, analyse and resolve functional demands and potential hazards
  • Potential options were scrutinised against key factors including safety, structural compatibility, mechanical compatibility, weight, and risk of wind damage
  • A balance of internal and external motion was chosen, with the east and west doors opening at precise angles to the building

 

Built and tested by experts

  • A simple, modular design enabled off-site assembly, for time and cost-efficient commissioning
  • Extensive Factory Acceptance Testing (FAT) at SCX’s Sheffield facilities was undertaken to fully review both functionality and safety before installation
  • Upon reassembly at the top of The Scalpel, further Site Acceptance Testing (SAT) took place to ensure a completely safe and reliable operation before handing over to the client

 

Versatile design

  • The complete door comprises of five modules that can be operated sequentially or individually
  • The doors are of a hinged design and each is powered by two hydraulic cylinders, sized appropriately for the task
  • The frame is made up of several bolted fabrications that are designed to leave a seamless facade when the doors are closed
