Transportation Forensic Engineering

When the design, operation or maintenance of transportation infrastructure is central to a claim or legal dispute, technical clarity is essential.

CIMA+ provides independent forensic engineering and expert opinion services in the field of transportation safety. Our work is grounded in current industry practice, regulatory standards and transportation engineering experience.

We assess how transportation facilities were designed, constructed, operated and maintained, and whether those conditions were consistent with applicable standards and accepted practice.

Our opinions are objective, evidence-based and ready to use in litigation, mediation, arbitration and claims resolution. They are grounded in real-world transportation engineering practice and are developed to be clear, defensible and ready for scrutiny in litigation and claim environments.

Engineering insight that supports informed decisions

We apply rigorous analysis to physical evidence, applicable standards and site conditions to determine:

• What occurred
• How standards and accepted practice apply
• Whether statutory duty-of-care obligations were met
• The implications for risk, liability and resolution strategy

Unlike general collision reconstruction firms, our focus is the transportation facility itself, its design, construction, operations and maintenance and how those factors influence safety and legal outcomes.

What we do: Clear, defensible engineering opinions

CIMA+ provides expert assessment and reporting that is:

• Objective and evidence-based – grounded in recognized standards and engineering practices
• Clear and actionable – prepared for legal counsel, insurers and adjusters
• Defensible – structured to withstand scrutiny in discovery, mediation and trial

Our opinion addresses questions such as:

• Were roadway design features, sightlines or signage consistent with industry standards?
• Did maintenance practices meet Minimum Maintenance Standards (MMS) or statutory obligations?
• Were winter maintenance or surface maintenance operations reasonable and consistent with contractual requirements, MMS (where applicable) and accepted practice?
• Did temporary traffic control measures or construction staging align with applicable standards and operational best practice?
• Were pedestrian, cycling or multimodal facilities reasonably designed and maintained?

How we support you through the legal process

We provide endtoend support aligned with litigation timelines and decision points:

1. Site documentation and initial assessment
   Early identification of what matters: what evidence is available, what may be missing and what should be preserved
2. Technical analysis and standards review
   Evaluation of site conditions, design elements, maintenance practices, traffic control, environmental factors and applicable standards or guidance
3. Clear reporting for decisionmaking
   Preparation of clear, structured reports setting out factual findings, technical analysis and independent engineering opinions for use in mediation, arbitration or litigation
4. Discovery and mediation preparation
   Technical preparation and consultation in advance of examinations for discovery, mediation and settlement discussions
5. Expert testimony
   When required, qualified experts provide testimony before courts and tribunals.
