Lindapter fixings provide high-integrity solution for 'adventure walk' addition to Brisbane's iconic Story Bridge

Lindapter steelwork fixings provided the ideal solution for safely attaching much of the flooring and walkway structures required to create the new 'Story Bridge Adventure Climb' — a recent addition to Brisbane's tourist attractions.

The climb takes tourists to the top of the 80 metre high Story Bridge, providing spectacular 360 degree views of the city from a vantage point over the River Brisbane.

Project engineers Dare Sutton Clarke chose to make extensive use of fixing clamps as the technology minimises any weakening effect on the primary steelwork and damage to the protective coatings that drilling and welding would otherwise cause.

Lindapter's fixings were preferred because of the company's quality manufacturing systems and its field-proven pedigree on many similar projects including the well known tourist climb way across the Sydney Harbour Bridge.

Various types of fixing are used on the structure. These include Lindapter floor fixings, which are highly resistant to vibration and avoid all need for drilling and welding, and Lindapter cavity fixings, which provide a safe means of connecting to the bridge's RHS (rectangular hollow steel) sections. In both cases, attachment could be made with access from one side only, in many cases eliminating expensive scaffolding and saving considerable installation time.

The new Story Bridge Adventure Climb is one of only three bridge climbs in the world - the others being Sydney and Auckland. The new walkway takes tourists up and over the first main pier to the centre of the cantilever bridge where they then cross over above the 6-lane road before returning back over the summit.

"The Story Bridge Adventure Climb really exemplifies the virtues of fixings in secondary steelwork," says Scott Brook of Lindapter's Australian support centre in Mount Druitt.

"The technology has minimised the effects on the existing primary steelwork and eliminated much of the on-site drilling and welding required, in many cases avoiding the need for scaffolding and platforms required for the operations as well. We're very proud to be associated with this prestigious project."

The Story Bridge was designed by Queenslander Dr John Bradfield. It took five years and 12,000 tonnes of structural steel and 1,650 tonnes of reinforcing steel to build and opened in 1940. It is 1,072 metres long from the southern to northern anchor piers, and the span across the River Brisbane is 282 metres.
