Exterior Building Drainage
In 2008 Transport For London (TFL) proposed a project to provide step-free access to Green Park. Work commenced in May 2009, to install two lifts from the ticket hall to the Victoria Line platforms and an existing interchange passageway giving access to the Piccadilly and Jubilee lines from the lower lift lobby. Component Developments worked with public health engineers and contractors to ensure that all of the renovations had sufficient and sustainable drainage systems.
When designing the system, Component Developments had a number of challenges they had to overcome. Firstly, being a tube station the volume of people whom would be walking over the drainage channels every day was overwhelming. Component Developments needed to design a system that could not only withstand this weight, but also a durable and long-term solution.
The systems designed by Component Developments included a 58mm wide slot drain (3604), and a 200mm wide 3010 drainage channel solution to manage rainwater run-off from the surrounding pavements. The drains included a built-in fall to one of the largest trapped gully types Component Developments supply. The gully included a waste basket, odour trap, rodding port and in the appropriate places, a DPM clamp. The size allows the system to effectively manage the hydraulic demands, whilst also accommodating for a much larger waste basket; thus decreasing the regularity of maintenance. Both solutions included a Heelsafe locked down grating, suitable for constant pedestrian traffic, whilst also, due to the smooth mesh, being suitable for suitcases and other wheeled objects regularly used by people on commute.
The step-free access project was completed ahead of schedule in August 2011, in time for use during the London 2012 Olympic Games.
