News: Eadon Consulting celebrate bridge opening

By

Innovative work by design engineers at Eadon Consulting in Rotherham is being showcased on the other side of the world as a new bridge opens in New Zealand.

The Hatea River Crossing, which is locally known as Te Matau a Pohe (the Fishhook of Pohe), is a pioneering bascule bridge which opened to both cars and pedestrians last month with the aim of easing traffic congestion around the city of Whangarei.

The 265 metre long bridge has a 25 metre long central lifting span to allow yachts to pass. The opening mechanism is based on a traditional rolling bascule bridge type, with the structural steel deck supports shaped to provide a distinctive elevation which speaks both of its rolling movement and also its cultural context - the curved "J" shape is an interpretation of the fish hook motif that is widely used in Maori culture.

Eadon Consulting, along with a group of specialised contractors, have been instrumental in the design of operating equipment and mechanical elements featured in the project.

Although the bridge has been fully functional for the last month, this official opening celebration, which includes a parade and flotilla, has helped showcase the bridge and generate worldwide recognition and interest.

Michael Thorogood, founder and company director at Eadon, said: "The project has allowed the complete team to showcase their combined skills in both the design and construction of the bridge and has delivered a project that the Whangarei region can be proud of."

Simon Weston, infrastructure services manager at Whangarei District Council added that "the bridge is a piece of international-quality architecture and engineering."

Based on the Advanced Manufacturing Park, Eadon staff are good at finding a solution to a highly complex or unusual challenge. Their design work spans across a number of sectors, with expertise in mechanical, structural, control and hydraulic design. They have worked on a wide range of projects including moving bridges, water control structures such as timber and steel lock gates, analysis of high integrity nuclear cranes as well as design of bespoke machinery and lifting equipment.

The firm has also recently secured the contract to design new moveable gantries for the Great Belt suspension bridge in Denmark with The Spencer Group.

The Hull-based engineering specialist has been appointed to carry out the largest retro-fitted bridge dehumidification project ever undertaken in the world. It follows on from similar projects with Eadon on the Humber Bridge and at Älvsborgsbron in Gothenburg.

The innovative "Cable Crawler" traversing system provides high-level access to main cables on suspension bridges and enables the negotiation of hand strand posts, hand wires and cable clamps without the need to return the gantry to the bridge deck. It eliminates traffic management after installation and has been designed to provide 100 per cent containment of personnel and tools.
