Exemplar Engineering Expert Reports

We produce both verbal and written engineering reports for various purposes such as engineering studies, machinery design audits and legal investigations for either defense or plaintiff.

We provide a verbal preliminary report shortly after our initial file review is completed. Should you require a formal written report, the two exemplar reports below illustrate our comprehensive written report format and two types of content.

Proper names and other identifying particulars have been removed to preserve the privacy of the persons and companies involved.

Exemplar Report 1: Auto / Tanker Truck Collision Accident Reconstruction

Exemplar Report 2: Runaway Work Truck Brake Failure Analysis



Auto / Tanker Truck Collision Accident Reconstruction

Reports are set in the context of a specific situation and varying theories. We produced this report for an automobile / tanker truck collision death case that went to trial. We and other witnesses testified and the jury ruled for our client.

We were brought into this case late. Police investigations had been completed, depositions had been taken and other engineering firms had investigated the accident and made or attempted to make computer reconstructions of the accident. The testimony of the only eye witness to come forward was being heavily attacked. Another issue was whether or not the truck driver had made a legal turn across a painted median in the roadway.

The damage to the striking automobile was extensive. The adverse party had presented a computer reconstruction and offered an opinion as to a very low vehicle speed for their client. Other engineering firms' computer reconstructions of the accident were questionable. We analyzed all the computer reconstructions made. The police accident reconstructionist had declined to make a computer reconstruction due to the extensive damage to the automobile.

After examining the evidence, we too declined to make a computer reconstruction. Computer reconstructions lose accuracy as vehicle damage becomes more extensive. Our presentation of our investigation focused rather on what accident scenarios were reasonable and believable, with vehicle dynamics examined for each of the different scenarios.

This exemplar engineering expert report illustrates these methods.



Runaway Work Truck Brake Failure Analysis

Industrial Exemplar Report - Runaway Work Truck

Here is a second exemplar engineering report, describing a fatal industrial accident involving a runaway truck.

This report uses mathematical calculations to demonstrate that only a very small quantity of brake fluid need be lost in order to completely lose brake pressure. The bulk modulus of the brake fluid was derived in order to allow calculation of fluid loss at the various pressures. This report demonstrates the sort of work we do to meet Daubert challenges.

Mr. Jeffers' testimony based on this report was instrumental to our client's winning at trial.
