What an engineering expert does in a property case

Property disputes often turn on technical questions: what caused the damage, when it happened, how far it extends, and whether a condition existed before the event in question. An engineering expert’s role is to answer those questions from the physical evidence and accepted engineering principles, and then to explain the answers clearly to counsel, to the parties and, if a matter goes that far, to a judge or jury.

Expert witness services at Elemental Forensic Services cover the whole of that role: an independent engineering opinion formed after examining the property and the evidence; a written report prepared for use in litigation when the matter calls for one; testimony at deposition and at trial; and litigation support for counsel along the way, from early technical consultation to an independent review of reports prepared by other engineers or experts in the matter, assessing whether their conclusions are supported by the physical evidence and accepted engineering methods.

Matters within scope involve residential properties and include wind, hurricane, tornado and hail damage; storm surge and flooding; water intrusion and moisture-related deterioration; roof and structural damage; fire damage to building components; and cracking, settlement, foundation movement or suspected sinkhole activity. When an opinion builds on an investigation Anna has already performed, the testimony rests on the findings and documentation developed during that investigation. When she is retained later in a case, the work starts with her own examination of whatever evidence remains available, and the opinion is limited to what that evidence can support.

How the work is done

Every engagement begins with a conflict-of-interest check, completed before any case materials are sent or reviewed. To run it, Anna needs only the names of the parties, the property address, the date of loss and the general nature of the dispute. The reason is practical: materials an expert receives or considers may later have to be disclosed to the other parties, and an engineer who has already reviewed one side’s materials on the same matter may face a conflict that affects both engagements. Clearing conflicts first protects your case and the integrity of the opinion.

Once the engagement is confirmed in writing, the work follows the same method as every investigation: Observe, Investigate, Document, Explain. The property and the physical evidence are examined as found. The circumstances of the loss are evaluated against the available records, weather data and construction information. Observations are documented with photographs, measurements and field notes. The opinions are then explained to counsel and, when the matter calls for one, set out in a written report that states the basis for each conclusion. Site inspections are coordinated with counsel, with notice to the other parties where appropriate.

Attorneys can expect a clearly stated methodology, a documented basis for every opinion, and candor about the limits of the analysis: what the evidence supports, what it does not, and what additional information could change a conclusion. Florida’s expert-testimony statute, section 90.702, Florida Statutes (the reliability standard often referred to as Daubert), asks whether testimony is based on sufficient facts or data, is the product of reliable principles and methods, and applies those methods reliably to the facts of the case. The file is organized so each of those questions can be answered from the record; whether an opinion is admitted is for the court to decide.

What you receive

  • A conflict-of-interest check completed before any case materials are exchanged.
  • Early technical consultation with counsel to define the engineering questions and the scope of the assignment.
  • Review of the documents, photographs and records produced in the case, including engineering reports prepared by other experts, with an independent assessment of whether their conclusions are supported by the physical evidence and accepted engineering methods.
  • A site inspection and documentation of the property, coordinated with counsel and with notice to the other parties where appropriate.
  • When the matter calls for one, a written engineering report prepared for litigation (scope, documents reviewed, observations, methodology, analysis, opinions and their basis, and limitations), signed, dated and sealed by a Florida-licensed Professional Engineer.
  • Preparation for and testimony at deposition and trial, as the matter requires, explaining the findings in plain language and staying within the engineering evidence.

Who this is for

  • Property owners already in a dispute over the cause or extent of damage, usually working through their attorney, who need an independent engineering opinion grounded in the physical evidence.
  • Insurance carriers and adjusters whose file has moved into litigation or a formal dispute and now needs an independent engineering opinion on causation.
  • Public adjusters whose clients' disputed claims may proceed to litigation, where engineering findings must hold up under examination from the start.
  • Attorneys handling property damage and insurance disputes who need an independent engineering opinion, an independent review of another expert’s report, or a witness who can explain technical findings to a judge or jury.

About expert opinions

Independent engineering opinions, deposition and trial testimony, and litigation support in property loss matters. Opinions are formed only after examination of the available physical evidence and are stated to a reasonable degree of engineering certainty. Anna Zimmerman, P.E. is retained for her independent professional analysis, not for a predetermined conclusion. Availability, scope and qualification to testify are determined case by case. Elemental Forensic Services does not provide legal advice, and no outcome of any claim or case is promised or implied.

Discuss a matter

Send the names of the parties, the property location, the date of loss and your deadlines, but no case documents yet. Once the conflict check is complete, Anna will let you know whether she can take on the matter and what the engineering scope would involve. Anna’s Statement of Qualifications (CV) is available to counsel on request.
