CASE STUDY: Point Resolution Bridge
A pedestrian bridge with flair!
CUSTOMER: Warren and Mahoney
PROJECT: Parnell Pedestrian Bridge
The designers of a new pedestrian crossing over Auckland’s busy Tamaki Drive didn’t want any old bridge – they wanted it to make a statement.
The bridge’s concrete beams were to be produced at Auckland company Wilson Precast. Incorporating the artist’s design into the formed face of the precast beams was a key challenge for the project.
It would also require Jackson to deploy the full extent of its comprehensive CNC machining capability to meet the scale of the required tooling. In fact, the unprecedented size of the project resulted in the largest flexible form-liner ever manufactured in New Zealand.
To construct the form-liner we created a master mould, made from our proprietary tooling board CaroC. The job required the use of a 3D model of the artwork and a computer-aided router to machine the design.
The final pattern was developed using a rubber form-liner we then fabricated from the master mould. This saw rubber poured into the master to create a flexible form-liner that could be added to the curved beam formwork, prior to the addition of reinforcing steel and concrete at Wilson Precast’s yard.
The bridge’s landmark features were recognised by three awards: NZIA Auckland Architecture Award – Public Architecture 2013; The Chicago Athenaeum and European Centre International Architecture Award 2014; and the SCNZ Award for Excellence in Steel Construction 2015.
This project had an incredibly short timeframe as there was only a short installation window available during the xmas period when the train lines had to be shut down for craning in of the three 90 tonne sections.
