Integrated Garrison, Aluminium Picket And Perforated Safety Fencing Upgrade

This multi-stage project transformed the fencing and security infrastructure of Birralee Childcare Centre in Willetton across four separate projects delivered during 2025 and 2026.

FencrGatr® worked closely with the client throughout, developing different fencing solutions for different areas while maintaining a coordinated black architectural palette and a strong focus on child safety, visibility, access control and long-term durability.

Stage 1 upgraded the front alfresco area with approximately 8 metres of custom welded vertical aluminium picket fencing at 1200mm high, together with a matching pedestrian gate. The replacement fencing improved the presentation of the entry and created a more secure and cohesive frontage.

Stage 2 addressed part of the external boundary, replacing old climbable chain-mesh fencing with industrial garrison fencing. Because the ground levels changed significantly, the panels needed to be stepped. Black Allywall retaining was installed beneath the garrison panels to close the resulting gaps and maintain a secure lower boundary.

Stage 3 focused on internal separation between children’s activity areas. FencrGatr worked through several options with the client, including extending the aluminium picket style used at the front. He also proposed a perforated fencing solution, allowing secure separation while preserving airflow, supervision and visibility across the centre. The client selected the perforated option, including decorative palm gates to soften the appearance within the childcare environment.

Stage 4 was the major perimeter-security upgrade. Approximately 117 metres of 2100mm-high black industrial garrison fencing was installed around the west, north and east boundaries to replace the remaining chain-link perimeter. This involved extensive removal works, extra-long posts, substantial concrete footings, changing ground conditions, mature vegetation and careful installation around an operating childcare centre.

FencrGatr® also coordinated the approvals process for the major works, including preparation and administration of council approval documentation and coordination of the required BA3 and Certificate of Design Compliance documentation with third-party professionals.

The completed project created a cohesive, site-wide security solution that balanced safety, visibility, controlled access, durability and presentation.

Client Expectations and Feedback 

The client’s requirements evolved from individual fencing upgrades into a complete security strategy for the childcare centre.

Safety was the central priority. Existing chain-mesh fencing presented climbability concerns, while internal fencing needed to securely separate children’s activity areas without obstructing educator supervision, airflow or visibility. External fencing was also needed to manage changing ground levels, eliminate low-level gaps and provide controlled access around the centre.

FencrGatr® worked collaboratively with the client throughout the project at every stage. Discussing alternative materials and design options, rather than applying one fencing style across the entire site. This resulted in aluminium picket fencing at the entry, stepped garrison and Allywall where terrain required it, perforated decorative fencing internally, and a substantial 2100mm garrison system around the external perimeter.

We also supported the client through the approvals process, coordinating council documentation, BA3 requirements and the Certificate of Design Compliance process with relevant third-party professionals.

The strength of the client relationship is reflected in the fact that Birralee repeatedly invited FencrGatr® back, commissioning four separate stages across 2025–2026.

When the final perimeter works were completed, the client and centre staff were relieved and delighted to see the long-running project finished. They thanked the team warmly and even joked that we should go home and celebrate with champagne – a memorable conclusion to a complex project that had become important to everyone on site.
