Hepburn Springs Pedestrian Bridge
Teleo provided engineering and project expertise to design, source fabrication, and manage construction, delivery and on-site installation of a suspension bridge in Victoria.
Teleo Design was awarded the tender from Hepburn Shire Council to design and construct a 32 metre pedestrian bridge across spring creek for the 150th anniversary of Hepburn's Mineral Spring’s Reserve.
The bridge designed was modelled on a suspension bridge, consisting of two CHS and a series of equal angles to support the floor and rod bracing for controlling the natural frequency.
The floor consisted of 21 fibre glass grating panels with 8 x 8 mm square holes.
The bridge was constructed as a single piece as to reduce installation and manufacturing costs.
A splice joint was designed originally, but once transport was confirmed that a single piece bridge was possible, the splice joint was no longer necessary and discarded from the design.
Four base plates were welded onto the bridge with pre-drilled slotted bolt holes to increase the ease and speed of installation at site.
The bridge was manufactured by HF Hand in six weeks at their Port Macquarie warehouse and then transported to Hepburn Springs in three days.
The site at Hepburn Springs was also prepared at the same time. Trees were removed from the desired bridge path to allow the crane to manoeuvre the bridge into position.
A single 90 tonne crane was used to lift the bridge from the back of the truck on the road into place in a single motion. The pilings required some slight manoeuvring to align the bolt holes correctly.
Screw pilings were installed at the appropriate coordinates to line up with the bridge base plates.
After the bridge was secured to the pilings a 500 x 500 x 2800 concrete headstock was poured around the piling to establish a sturdier base for the bridge.
The Bridge was delivered on time and on budget, with minimal impact to surrounding residents. Installation was completed within a 3 hour period.
