Who Retains MarcorSEN

Forensic engineers are retained when a structural question becomes a legal one.

MarcorSEN is engaged by counsel, carriers, and owners — typically when a structural failure, defect, or weather event has crossed the line from a maintenance question into a claim, a dispute, or active litigation.

/01

Attorneys

Plaintiff and defense counsel in construction-defect, insurance-coverage, premises-liability, and CPUC proceedings. Marcor authors the report, sits for deposition, and testifies at trial — in federal court, state court, juries, arbitration panels, and regulatory commissions.

/02

Insurance Carriers

Property and casualty carriers needing causation analysis on first-party and third-party claims — wind, hail, hurricane, flood, fire, and construction-defect losses. Reports are written to survive bad-faith and coverage-counsel scrutiny.

/03

Building & Utility Owners

Owners, HOAs, public utilities, and asset managers needing an independent engineering opinion on structural adequacy, continued-use suitability, code compliance, or repair-versus-replacement decisions on damaged or aging infrastructure.

Focus

The three lenses applied to every investigation.

/01

Natural Disaster Building Impact

Marcor has studied the impact of hurricanes, tornadoes, vibrations, floods, hail, and high winds on roofing, framing, and foundation damages — across residential, commercial, and industrial buildings and other infrastructure.

/02

Failure Causation

Marcor provides insight into the causation of building failure — whether soil, moisture, lack of maintenance, or standards of construction — and the chain of events that led from precipitating cause to observed damage.

/03

Adherence to Building Codes

Marcor studies whether a building failure has resulted from a lack of adherence to building codes — applying the IBC, state amendments, and historical code editions to determine compliance at the time of construction.

Industry Press

Interviewed on forensic structural engineering and expert testimony.

In a podcast interview, Marcor discussed forensic structural engineering practice and the role of the expert witness in modern litigation — how investigations are scoped, how reports are written to survive cross-examination, and what attorneys should look for in a retainable engineer.

“Marcor Platt is always my first choice for a Forensic Engineer. I retained Marcor in an insurance bad faith case arising from a homeowners insurance claim plaintiffs made after a wind and rain storm. Marcor conducted a thorough site inspection, prepared an excellent (and easy-to-read) report, and was an outstanding expert witness at trial. The jury loved him! He explained difficult concepts to the jury in a humble, comprehensible way and held up exceptionally well under ri…”

“I worked with Mr. Platt as an expert witness in a case where we needed his review and testimony related to engineering issues, particularly with regard to the construction and repair of residential real property. I found his inspection to be extraordinarily thorough, and that was reflected in his well-written report and the numerous photos he provided. We were unable to resolve the case and had to go to trial. I found Mr. Platt's testimony to the jury to be extremely helpf…”

“I worked with Marcor Platt, when he was employed by Wright Engineering in Phoenix Arizona, on a project in one of our buildings in downtown Scottsdale. Around March of 2020, while in the process of completing a tenant improvement project for a new restaurant, we discovered that the subject building was constructed with deficient loads for public assembly/restaurant use; and would require a structural retrofit to address both flexural and punching shear issues. Marcor was t…”
