Diagnostech: The Only Remedial Consultants with an iCIRT Rating - and Why It Matters
At Diagnostech, restoring integrity is more than a tagline, it is the foundation of every decision we make and every project we deliver. As the insightful, honest, knowledgeable and authoritative voice of remedial building, our commitment to integrity, technical excellence and client advocacy has shaped our reputation since 2002.
That commitment has been independently recognised once again with a milestone achievement:
As it stands, Diagnostech are the only consultants specialising in the remedial building sector with an iCIRT star-rating. Our Gold 4.5 star-rating ranks us among some of the most trusted and respected building professionals in the industry.
Use of iCIRT star-rating is subject to Equifax’s terms, exclusions &/or disclaimers available
at www.buildrating.com or scan QR code for details of this particular iCIRT star-rating.
This rating matters is not just for us, but for every owner, strata manager, investor and asset manager seeking reliability and accountability in remedial building.
Why iCIRT Matters to Diagnostech
The iCIRT (Independent Construction Industry Rating Tool) star‑rating, developed by Equifax in consultation with government and industry, is designed to give the construction sector a transparent benchmark of trustworthiness, capability and compliance.
The rating evaluates thousands of public and private data points across six criteria:
- Capability
- Conduct
- Character
- Capacity
- Capital
- Counterparties
This rigorous assessment confirms whether a business has the systems, processes, stability and integrity required to consistently deliver safe, compliant and durable building outcomes.
For Diagnostech, achieving this rating is far more than a credential it is validation of the values that already define who we are.
This rating is ultimately a reflection of our people and our values in action. Their technical expertise, their care for clients, their refusal to compromise on quality, that’s what built Diagnostech’s reputation. I couldn’t be prouder of the team and the culture we’ve created together”

A Rating That Aligns with Our Values
Integrity‑Driven
Diagnostech leads with integrity and an unwavering independent stance to achieve the best outcomes for our clients. This value is explicitly embedded in our operating philosophy and project approach. The iCIRT rating independently confirms that commitment.
Knowledge First
As a firm recognised for its deep technical expertise — spanning diagnostics, building defect investigations, specifications, engineering and remedial design — knowledge is the backbone of every decision we make.
iCIRT’s rigorous analysis demonstrates that our systems, governance and technical foundations meet the highest industry standards.
Practical, Real‑World Outcomes
Our projects balance technical rigor with real‑world practicality to create solutions that work — and stand the test of time.
iCIRT confirms that our capability is supported by operational resilience and the capacity to deliver consistently.
Commitment Throughout
From initial evaluation through diagnostics, technical specification, DBPA compliance and project management, Diagnostech delivers end‑to‑end guidance with continuity and care.
The star rating reflects the strength of these complete‑lifecycle processes.
Why iCIRT matters to you
While obtaining an iCIRT rating is not mandatory, it offers clients a trusted way to verify the credibility of a consultant — critical in the remedial sector where risks, costs and compliance responsibilities are significant.
Working with an iCIRT‑rated business gives you assurance that the consultant has been independently evaluated for:
- financial stability
- legal and regulatory compliance
- strong governance
- proven, reliable industry performance
- capacity to deliver safe and compliant outcomes
This is why we encourage clients to always check for an iCIRT Build Star‑rating when engaging any consultant or contractor.
Our Ongoing Commitment
The introduction of the DBPA has raised expectations and increased complexity across the building industry. Despite these challenges, our stance remains clear and immovable.
Diagnostech is committed to transparent, compliant, and technically sound outcomes—every project, every time’’
– Tom Mackay, Director
Our role extends beyond delivering technical expertise — we empower clients to make informed decisions by helping them understand:
- what high‑quality remedial practice looks like
- how to identify consultants and contractors who prioritise compliance
- the red flags that indicate potential shortcuts or risk
By embedding integrity, knowledge and practical leadership into everything we do, we continue building confidence in the remedial industry — one project at a time.

What our clients say
"
Diagnostech were engaged by the owners corporation to investigate the cause of the water ingress affecting several apartments and provide recommendation for remedial repairs. David Chan has been an amazing engineer to work with, taking the time to explain in layman terms the cause of the fault, how the water enters the building and metholdology for repairs to comply with the legal requirements.
– Samantha Walker, Strata Assistant, Bright & Duggan
I have had the pleasure of working with Diagnostech on our current live project, and I can’t speak highly enough about the experience! From start to finish, their professionalism, expertise, and attention to detail were exceptional. Swahil Patil, Theriza and Raj took the time to thoroughly assess the complex issues and address them to ensure full compliance. Their wealth of knowledge is impeccable.
I highly recommend Diagnostech for any remedial engineering work. It’s rare to find someone so reliable and skilled, and I will definitely be reaching out for any future needs!
