Wetherill Park – The leaning fence
Special Considerations / Challenges
- With regards to the fence, safety was of primary importance.
- Although it was unlikely to fall, the fence needed to be propped whilst a suitable solution was determined.
- As is so often the problem with retaining walls, the key challenge was the drainage.
- Therefore, it needed to be demolished and rebuilt or a suitable alternative which needed to be both feasible and approved by Council.
The SIGA Solution
- Initial structural assessment and provision of report and details for propping.
- Suggested options for design solution.
- Preparing design solution for consideration by Council.

- Documentation of remedial repair details.
- Inspections during topping pour.

Parramatta - Repairs to Concrete Degradation
Special Considerations /Challenges
Concrete cancer had affected the underside of the walkway to the weir and Siga was contracted to provide instructions on the rectification works. Pedestrian access of the walkway during the repairs needed to be considered as was flooding to the weir when it rains!
The SIGA Solution
Determining suitable solutions and material with the builder to cater for the submerged environment that the repairs would be exposed to.

Bellevue Hill - Structural Opinion
Special Considerations / Challenges
Retaining wall failure
The SIGA Solution
Provided professional discussions and advice on site and a subsequent report detailing our view that the failure occurred as a result of excavations next to the wall, combined with poor initial design for the load conditions.
