Frame Group Ltd

Ever wondered how a Suspension or Swing Bridge is found to be safe for the public?
Here's a look at the process we follow at Frame Group to ensure that our suspension and swing bridges undergo rigorous safety measures before being opened to the public.

Load testing involves:
1. Setting up: Using a 2000L bladder and placing it in the middle of the deck of the newly completed bridge. As part of the setup Engineers inspect and collect important data and measurements.

2. Filling the bladder with water pumped from a nearby stream, river or Lake. In some remote locations water is flown in by helicopter. The filling of the bladder replicates the weight of multiple people standing on the bridge.

3. During the filling process Engineers monitor the bridge and watch closely for other signs of unwanted structural behaviour.

4. Once the Engineers have fully loaded the bladder with a pre-determined amount of water, the Engineer compares the original set-up data and measurements with the new fully loaded bridge data.

5. Finally, pulling the release valve (remotely) and enjoy the waterfall.
Next time you cross one of our bridges, we hope this gives you even more confidence in its safety!

Frame Group also works closely with our clients to regularly assess the safety of existing structures, ensuring they are fit for public use.

It's fantastic to see the Te Araroa Trust continually striving to enhance the trail, both in terms of the overall experience and safety. These efforts will provide walkers with the chance to explore more of Aotearoa New Zealand, all while minimizing exposure to highways whenever possible. Check out the link below to read more about one of the Trusts latest projects.

This project provided an excellent opportunity for Erick Quinto, one of Frame Group’s Senior Draughtspersons, to showcase his exceptional 3D modeling skills. His expertise in Revit modeling, detailing, and rendering brings a dynamic, third-dimensional quality to both concept and detailed designs, elevating the overall impact of Frame Group’s projects.

Have you heard the news? Aotearoa has a new Great Walk! 😊 Tuatapere’s Hump Ridge Track.

Situated approximately 30 km from Tuatapere the track provides varied landscapes such as rugged coastline, sandy beaches, native forests, historic viaducts, and spectacular sub-alpine views. This region is steeped in narratives of mana whenua/iwi and rich history such as the old Port Craig Sawmill and three historic viaducts (Edwin Burn Viaduct, Percy Burn Viaduct, and Sand Hill Viaduct).
Frame Group had the opportunity to work with the Department of Conservation on the track and structures upgrades.

This work includes:
Edwin Burn Bridge: 61.2m long×0.6m wide swing bridge.
Re-shaping the existing track, grade adjustment and forming new track segments with aggregate surfacing.
Installation of track drainage, including side drain, grade dips and culverts.
Installation of timber boxed steps with aggregate surfacing and edge boards.
Installation of pegged timber boardwalk with stepped segments.

Frame Group also designed, and construction monitored the additional structures along the South Coast Track:
Angus Burn Bridge: 33.5m long×0.3m wide swing bridge
Aan River Bridge: 36.5m long×0.3m wide swing bridge
Wairaurahiri River Bridge: 55m long×0.3m wide swing bridge
