Media City Swing Bridge

Media City Swing bridge is a pedestrian footbridge with an unusual structure. The deck is supported using a series of cable stays, that are supported on masts. The mast structures have a spherical knuckle bearing at their base to allow any rotation if required. These bearings are critical to the mast structures functioning correctly. Eadon Consulting Ltd were employed to carry out an independent check of the mast bearings for this unusual application.

The category 3 check of the bearings involved a review of the overall design to ensure it was suitable, and then completing an independent check of the bearings producing a set of design calculations. The bearings are a combination of stainless steel and a Lubron low friction material. Eadon Consulting used previous experience of bespoke structural bearing design to ensure a thorough check was completed in a timely manner for the project team.

The structural consultant for the bridge design was Gifford & Partners LLP and the architect Wilkinson Eyre. Various options and designs were investigated and presented to the client. From this a design was selected for development to tender stage.

The exemplar mechanical, electrical, control and hydraulic design and specification of the Media City Swing bridge was carried out by M G Bennett and Associates Ltd. Whilst employed by Bennetts, Michael Thorogood was responsible for the detailed exemplar design and specification of the mechanical, electrical, control and hydraulic elements.

The final design is a 83m long bridge consisting of a nose span of 65m with a tail span of 18m. In order to allow the passage of vessels, the bridge rotates about a vertical axis through 71 degrees.
