This project involved like-for-like roof replacement on the ancillary toilet block at the National Art School (former Darlinghurst Gaol), 156 Forbes Street, Darlinghurst NSW 2010—a State Heritage Register item. Works included new tin roofing sheets, treated pine framing, insulation, Gyprock ceiling linings, repainting of internal ceiling and walls with compatible paints, new lighting and temporary removal/reinstallation of windows with resealing.

The toilet block and its roof, linings, finishes, and windows are non-significant fabric; the site’s heritage significance stems from its 19th-century gaol structures, sandstone elements, and cultural history, none of which were affected.

In the live educational environment (ongoing classes, students, and foot traffic), challenges were managed through enhanced supervision, phasing around the timetable, temporary alternative toilet facilities, dust/noise controls, barriers, daily inspections, work-zone demarcation, and coordination with campus management—ensuring minimal disruption and zero interaction with significant heritage elements.

Protective measures included debris containment, protective coverings, trade briefings on heritage boundaries, and strict limitation to the toilet block area. The works preserved the structure’s appearance and function without physical, visual, or associative impact on the item’s overall significance. Supporting records (photos, compliance details) were maintained for the exemption form.

Volmac Group is proud to have collaborated closely with Schools Infrastructure NSW to successfully deliver a modern, freestanding classroom at Chifley College Shalvey Campus — creating an inspiring, future-ready learning environment for Year 7–10 students in Western Sydney.

As the full design-and-construct head contractor, Volmac took complete ownership from concept to handover. Our in-house multi-disciplinary team managed every stage with precision: bulk and detailed excavation, comprehensive civil works, structural engineering for a solid foundation, high-quality concrete slab pouring, robust metal framing erection, plus full installation of new electrical sub-mains, power distribution networks, contemporary LED lighting, fresh plumbing services, and energy-efficient air conditioning systems.

By leveraging our integrated civil, structural, electrical, mechanical, and hydraulic expertise — all under one roof — we delivered a seamless, turnkey solution that minimised disruption to daily school operations, ensured the highest standards of quality, safety, and finish, and met strict government compliance.

Completed on time and within budget, this durable, sustainable classroom stands as a testament to Volmac’s commitment to building educational spaces where students can learn, grow, and thrive — aligning with NSW public education goals and our zero-emission service delivery ethos.

Volmac Group was thrilled to secure the full design and construct contract from Schools Infrastructure NSW for a free-standing shed — a complete turnkey project delivered 100% in-house with no subcontractors.

We managed every phase end-to-end: concept development and engineering design, site civil works and foundations, full electrical fit-outs power distribution, lighting, and compliance, plumbing installations, and building construction including structural steel, cladding, roofing, and fit-for-purpose finishes.

This project highlights Volmac’s competitive edge in the education infrastructure sector: we win bids through intelligent, value-engineered pricing, then leverage our fully licensed, in-house building division alongside dedicated electrical and plumbing teams to deliver exceptional quality, strict timeline adherence, tight cost control, and seamless coordination — all while maintaining our commitment to sustainable, zero-emission site practices via our electric fleet.

The result is a durable, functional shed built to withstand heavy use in a school environment, providing reliable storage or operational space that supports NSW public education goals.

Volmac Group proudly delivered a comprehensive new fire services system for Create NSW as part of the landmark refurbishment of the historic Darlinghurst Police Station – now transformed into Qtopia Sydney Australia’s first dedicated LGB+ museum and cultural centre.

This high-profile heritage project involved installing a fully addressable fire detection network (smoke and thermal detectors), new fire hose reels throughout the building, a motorised roller shutter with integrated UPS backup power, and multiple fire trip interfaces to ensure seamless integration with the building’s overall safety systems.

Working within a sensitive, heritage-listed site during active refurbishment phases, our team coordinated meticulously to meet strict conservation requirements, minimise disruption, and deliver compliant, reliable fire protection that safeguards both people and priceless cultural exhibits.

The upgraded system provides state-of-the-art early warning and response capability, supporting Qtopia Sydney’s mission as a vibrant, inclusive space for history, art, and community.

This project highlights Volmac’s expertise in complex fire services installations within heritage and public cultural buildings – delivering precision, compliance,
