About Diact
Diact is a multidisciplinary partnership of senior engineering practitioners, combining deep expertise across structural, electrical, mechanical, HVAC, materials, and fire disciplines. We execute every phase of an investigation directly, ensuring that the expert who authors the final report is the same practitioner who directed the investigation, examined the evidence, and conducted the analysis.
How We Investigate
Our senior practitioners remain directly involved in the field and the lab, handling evidence preservation, analysis, and reconstruction firsthand. By maintaining this hands-on involvement on every file, we preserve the scientific integrity and technical precision of our findings.
Objective Technical Analysis
We test every hypothesis against the physical evidence, and guard against the bias of settling on an early theory. Clear technical facts and initial opinions, delivered early in the investigation, provide counsel and insurers the information required to evaluate liability, negotiate settlements, and resolve disputes.
Who We Serve
Our senior practitioners maintain strict confidentiality while delivering root-cause analysis and litigation support across three core sectors:
Property & Casualty Insurers
When the file demands more than a standard cause-and-origin report.
We manage high-value, complex files where the route to resolution is obscured by contested causations, voluminous records, or multi-faceted technical exposures. Our practitioners deliver the forensic engineering precision needed to clarify coverage and liability on major property losses.
National Legal Counsel
Technical findings built to withstand cross-examination.
We provide forensic analysis and litigation support for complex dispute resolution. From subrogation recovery and liability defense to multi-party conflicts arising from major infrastructure and Public-Private Partnerships (P3), we deliver clear, defensible technical findings that counsel can rely on.
Corporate & Industrial Operations
Protecting operational continuity in mission-critical environments.
We conduct failure analysis and operational risk mitigation for mission-critical facilities. Our team is trusted to protect continuity and investigate failures in high-profile and secure environments—ranging from uptime-sensitive data centers and financial hubs to pioneering technological platforms, highly secure public-sector installations, and sensitive investigations subject to the highest levels of scrutiny.
Our practitioners are regularly qualified as expert witnesses, with testimony accepted in provincial courts and arbitrations nationwide.
Our Disciplines
Our practitioners bring focused expertise across six core engineering disciplines:
- Civil/Structural — Collapses, structural and building envelope failures, fire, explosion, climatic and impact damage assessment
- Electrical — Rotating equipment, transformers, automation systems, power distribution
- Fire — Fire and explosion origin and cause investigation, electrical and mechanical ignition sources
- Mechanical — HVAC systems, piping, boilers, industrial process equipment
- HVAC — Air handling, ventilation design failures, energy system diagnostics
- Materials — Metallurgical failure analysis, corrosion assessment, product and material defects
Engaging Our Team
Every major loss presents unique technical and legal challenges. We begin every potential engagement with a candid, confidential discussion to understand the scope of the matter and determine if our multidisciplinary expertise is the right fit for your file.
