"Finding the truth from their own words"

I specialise in examining expert reports to reveal what is supported, what is overstated, and what the evidence truly shows. Through structured technical and compliance review, I help the legal dispute process by revealing the truth based on the facts or lack thereof.

Common weaknesses Exredis uncovers in Expert Reports

Exredis reveals the following common issues with expert reports in building, construction and engineering disputes...

1. Lack of independence or objectivity

2. Poor methodology or unsupported conclusions

3. Failure to use the correct standard or understand the engineering behind it

4. Inadequate site inspection or insufficient evidence

5. Experts working outside their area of expertise

6. Non‑compliance with expert evidence rules

7. Overreaching or advocacy‑style writing

8. Poor structure, clarity, or technical communication

9. Inadequate cost estimates or unsupported rectification scopes

EXREDIS CORE SERVICES

1. Early Technical Case Assessment

Purpose: Early, simple identification of technical issues before committing to expert engagement or substantive casework.

What this includes:

  • Review of the client’s factual narrative, affidavit, or statement for technical accuracy, sequencing, and mechanism clarity

  • Identification of technical misunderstandings, contradictions, or gaps that may affect later expert engagement

  • Initial scan of technical issues which may relate to the HBA, SoPA, Contract, DBP Act, or ACL

  • Early procedural and evidentiary risks

  • Plain‑language explanation, to solicitor on record

Benefit: Helps solicitors and their clients save money, by deciding whether to proceed, settle, escalate, or continue and brief an expert.

2. Pre‑Expert Briefing Alignment

Purpose: Ensure the expert is briefed accurately, comprehensively, and in alignment with the technical issues in dispute.

What this includes:

• Identification of technical issues that may interact with the HBA, SoPA, Contract, DBP Act, or ACL

• Identification of applicable NCC and AS/NZS standards

• Examination of technical causation pathways

• Structured, standards‑aligned scope for expert engagement

Benefit: Prevents mis‑briefing, scope drift, and incomplete expert opinions; reduces expert costs; and ensures alignment between the solicitor’s legal theory and the technical evidence.

Compliance note: Any references to legislation are limited to identifying where technical issues may intersect with statutory frameworks. Legal advice, interpretation, and pleading decisions remain solely with the solicitor on record.

3. Forensic Dismantling of the Expert Report (Applicant or Respondent)

Purpose: Determine whether the expert report is technically sound, evidence‑based, procedurally compliant, and correct in its analysis of causation.

What this includes:

  • Revealing errors, unsupported assertions, contradictions, and inconsistencies

  • Assessing methodology and reasoning

  • Identifying the correct applicable building, construction, engineering, and procedural standards

  • Determining any departures, omissions, or failures to comply

  • Assessing whether the proper cause or causes were considered

Benefit: Identifies vulnerabilities before the other side does; avoids reliance on defective or non‑compliant expert evidence; informs whether a replacement expert is required.

NOTE: A severely deficient applicant’s expert report can remove the need for a respondant's expert report — the quickest win (and most satisfying) is showing their evidence has no weight, and cannot sustain the claim.

4. Technical Evidence Testing & Hearing Support

Purpose: Convert the technical findings from services 2 and 3 into structured, standards‑aligned material that supports counsel in preparing for mediation, directions hearings, and final hearing.

What this includes:

  • issue‑by‑issue analysis of the opposing expert’s technical reasoning

  • identification of gaps, unsupported assumptions, and standards inconsistencies

  • mapping of technical vulnerabilities in the expert’s methodology

  • raising technical questions that may assist counsel in testing the evidence

Benefit: Provides counsel with a clear understanding of the technical strengths and weaknesses in the expert evidence, supporting the development of case theory and hearing preparation.

All legal strategy, advocacy decisions, and cross‑examination remain solely the responsibility of the solicitor and counsel.

5. Residential Building - Legal Education

Purpose: Conduct CPD presentations for generalist solicitors, who want to better understand the legal framework around residential home building work in NSW.

Benefit: Solicitors can gain an understanding of the Home Building Act, Security of Payments Act and Design and Building Practitioners Act and how this legislation applies to protect their (homeowner) clients.

6. Technical Review – Insurance Repair Scopes

Purpose: Clear, independent review of an insurer’s repair scope to check whether it properly reflects the actual damage and the work reasonably needed to fix it.

What this includes:

  • Review of the insurer’s builder assessment or repair scope for accuracy, completeness, and whether the proposed work matches the real damage

  • Identification of missing items, unreasonable exclusions, or assumptions that don’t line up with how the damage actually occurred

  • Check of construction method, sequencing, and Building Code compliance issues that may affect the quality or safety of the repair

  • Correction of common misunderstandings (for example, when owners or builders believe they must provide three quotes, when the insurer’s scope limits repairs, settlement offers are very low)

  • Plain‑English explanation to the builder or homeowner about what is missing, what is reasonable, and what may need to be added before quoting or accepting an insurer decision

    Benefit: Helps builders and homeowners understand whether the insurer’s scope or settlement amount is enough to repair the property properly and in line with Building Code requirements. This reduces the risk of under‑scoping, ensures the work can actually be completed to standard, and supports fair settlement discussions.

7. Consumer Law - Engineering Analysis

Consumer Law Support with Practical Engineering Insight

Some consumer disputes can benefit from simple, clear engineering input. Because I work across civil/structural engineering, construction materials, and the law, I can explain

  • why something has gone wrong,

  • whether an occurrence is feasible or impossible

  • using established engineering principles, and

  • demonstrate this through transparent calculations and objective reasoning.

My approach combines:

• applying straightforward engineering principles

• clear, plain‑English explanations

• an understanding of statutory warranties and consumer rights

This helps consumers resolve issues efficiently, without unnecessary conflict or confusion.

About the Principal

About the Principal

About the Principal

My name is Nick Kastoumis, I grew up in and am based in Sydney.

I am a civil/structural engineer with more than 24 years’ experience in technical, compliance, materials innovation, and client‑facing/training roles, and in early 2024, I was admitted as a solicitor of the Supreme Court of NSW.

I have worked in building and construction for over 40 years.

In the early 2000's I received my NSW Building Contractors Licence and contracted for a couple of years, but did not renew it as contracting was not for me.

In 2002, I began a career in geosynthetics, which are geotechnical materials. These specialty materials, are used as critical components in the civil, road, rail, environmental and mining sectors.

In 2009, I set up my own geosynthetic consultancy, working with major overseas manufacturer's helping them deliver their products and systems into the Oceania infrastructure market.

With Tier 1 and 2 consulting engineers - I developed and provided design specifications, detailed designs, MQA and costings

With Tier 1 and 2 Civil contractors - I developed onsite installation methodology, SWMS and installation training as well as construction CQA for these materials and systems.

Exredis was founded on a lifelong, unrelenting passion to uncover the truth—to understand it, embrace it, and bring it to the surface. As John 8:32 reminds us, “the truth will set you free.”

By combining this commitment to truth with my experience across engineering, construction, and law, I aim to contribute to the efficient administration of justice in building and engineering disputes. My focus is on promoting fair and equitable outcomes grounded in real truth, honesty, accountability, and fairness.

Truth is not always convenient, but when we discover it and embrace it, we can move forward and become better for the experience.
