Frequently Asked Questions
Why should we engage a Class 2 Registered Building Practitioner instead of a general builder?
For regulated Class 2 works, engaging a registered building practitioner ensures the project is delivered in accordance with declared design, the NSW Design & Building Practitioners Act, and all relevant statutory obligations.
This protects your owners corporation by ensuring:
• The works are executed exactly as designed
• Compliance responsibilities are clearly defined
• Required inspections and documentation are properly managed
• The risk of defects, disputes, or regulatory issues is reduced
Using a registered practitioner provides clarity, accountability and protection — particularly where structural, waterproofing or façade works are involved.
How do we know whether our project actually triggers DBP obligations?
Many Class 2 remedial and upgrade projects trigger DBP requirements without owners realising it.
Works that commonly require a registered practitioner include:
• Structural concrete repairs
• Slab remediation or strengthening
• Waterproofing affecting building elements
• Façade or cladding remediation
• Balcony, podium or rooftop upgrades
During a Project Desktop Review, we assess your scope, engineering documentation and building type to confirm whether DBP obligations apply — before construction begins.
This prevents compliance exposure and mid-project delays.
How do you ensure the works are delivered strictly in accordance with declared design?
We execute construction strictly in line with the engineer’s declared design and coordinate required hold points, inspections and sequencing controls.
This includes:
• Pre-construction review of drawings and documentation
• Identification of investigation requirements prior to commitment
• Structured inspection records• Compliance-aligned supervision on site
• Clear documentation confirming delivery in accordance with design
This approach protects both the engineer’s intent and the owners corporation’s compliance position.
What documentation and protection does the owners corporation receive at completion?
At completion, the owners corporation receives documentation confirming the works were delivered in accordance with declared design and applicable regulatory requirements.
This provides:
• Clear evidence of compliant execution
• Reduced risk of future disputes
• Protection for committee members
• Stronger records for future asset management
We operate with structured documentation and traceability to ensure there are no grey areas once the project is complete.
Can you safely deliver works in occupied residential buildings?
Yes. Most of our Class 2 projects are delivered in live, occupied buildings.
We manage this through:
• Controlled staging and access planning
• Resident communication protocols
• Risk-managed sequencing
• Dedicated site supervision
• Safety controls aligned with high-density environments
Our objective is to protect residents, maintain programme control, and deliver the works responsibly without creating unnecessary disruption.
What size projects do you undertake?
We deliver projects from $20,000 repairs through to $2–5 million multi-stage upgrades.
Project size is less important than scope complexity because we apply the same structured controls, supervision standards and documentation regardless of project size.
