Project Overview

United Contracting was engaged as part of the NSW Police Property Group’s infrastructure upgrade program to deliver a critical acoustic refurbishment at the Albury Police Station. The project involved the design and construction of two ERISP rooms and a Soft Interview Room to meet stringent acoustic performance and privacy standards as set out in the NSW Police Building Code and Australian Standards.

Given that the Albury Police Station operates 24 hours a day, the project required meticulous planning to ensure no interruption to daily police operations while delivering high-quality, compliant acoustic environments.

Project Goals and Challenges

The NSW Police identified the need to:

• Create acoustically rated rooms to ensure confidentiality in investigations and interviews.
• Upgrade existing facilities that did not meet Rw (Weighted Sound Reduction Index) performance requirements.
• Complete the works within an operational police facility without disrupting ongoing law enforcement duties.

Key challenges included:

• Maintaining one operational ERISP room throughout construction.
• Managing restricted site access, security vetting, and after-hours works.
• Ensuring all construction complied with Police Property Group (PPG) standards and Australian building codes.

Results

✅ Achieved Rw50–55 acoustic performance as verified by post-completion testing by JHA.

✅ Delivered zero operational downtime for the police station.

✅ Fully compliant with NSW Police Property Group standards, AS/NZS acoustic standards, and Downer’s Quality Policy.

✅ Provided durable, low-maintenance, and compliant facilities enhancing confidentiality and comfort during sensitive police operations.

The project involved the construction of a suspended ceiling system, bulkhead works, acoustic ceiling tile installation, fire protection system upgrades, and mechanical (A/C) reconfiguration, all in compliance with Australian Standards AS2118.1–1999.

United Contracting’s role was pivotal in ensuring that all works complied with building certification requirements — particularly through a BIC (Building Information Certificate) application, necessitated by prior unauthorized works already completed on site.

Project Goals and Challenges

Skyzer required assistance in:

• Bringing existing mezzanine works into compliance for certification approval.
• Upgrading fire protection systems and ensuring AS2118.1–1999 compliance.
• Coordinating complex mechanical and structural integrations within an existing operational facility.

The main challenges included:

• Rectifying unauthorized existing construction under a BIC application framework (where a new CDC could not be issued).
• Integrating multiple trades and compliance disciplines, including building, fire, and mechanical services.
• Delivering the works while maintaining full operational continuity for Skyzer’s production environment.

Construction and Services Upgrade

United Contracting delivered a full fitout and services integration, including:

• Suspended ceiling construction to specification.
• Bulkhead construction to stair area, seamlessly integrated with architectural finishes.
• Installation of ceiling tiles and aluminium angle detailing on all steel columns for a professional finish.
• Sprinkler system adaptation to connect with the existing K17 system for high-hazard occupancy — meeting a 7.5mm/m² over 260m² design criterion.
• Installation of below-ceiling (K11.5), in-ceiling (K5.6), and exposed (K11.5) sprinkler heads for precise fire coverage.
• Refit and ducting of four A/C systems, including system assessment, reconfiguration, sealing, insulation, and balancing.

Testing, Documentation, and Handover

• Conducted testing and commissioning of mechanical and fire systems to verify functionality.
• Provided as-built drawings, installation documentation, and full compliance reports for the certifier.
• Managed BIC documentation and liaison with the principal certifier to secure compliance certification for the client.

Conclusion

The Skyzer Network Mezzanine Fitout Project demonstrates United Contracting’s expertise in managing complex building compliance, fire safety integration, and construction delivery under challenging conditions.

By combining technical knowledge, regulatory understanding, and trade coordination, United Contracting successfully converted an unauthorized structure into a fully certifiable facility — reinforcing its reputation for reliability, quality, and precision in building compliance and infrastructure delivery.
