The crash scene can be a complex mixture of physical evidence and conflicting witness statements. Lives are forever changed by the forces of a crash, and most of the time questions regarding key issues remain unanswered. That's why we believe that the work we do as crash reconstructionists is so vitally important. Learning the inherent truths about transportation crashes is a major step in the process of determining how the crash occured and who or what may have been at fault. 
WHAT'S IN A NAME? The Company name Introtech is comprised of the two key elements that describe our approach to an issue; Introspective approach using the vast experience and training of a large and dedicated staff. Technology utilizing our instruments, tools, technology and computers to compliment our experience and training. It is through our introspective and technological approach to a question or issue that we develop our opinions to the best of our ability and as accurately as possible.
An accurate opinion about a crash must be based upon a correct and proper analysis of the physical evidence, additional research, accurate calculations and experimentation. Introtech strives to completely analyze and investigate all of the available facts about the vehicles, crash scene, witness statements, photographs and other data. This evidence provides key information about how the crash took place. Proper interpretation of the collected data is important to develop a clear understanding of the facts, finding undetected variables and to understand what they mean. We use state of the art technology to assist in our investigation process including:
- Total Station Forensic Mapping instruments (including profile and topography capability)
- Accelerometers
- Lasers
- RADAR
- Computer simulation programs
- Software to download electronic data from vehicle electronic control modules and crash data retrieval data from air bag sensors
- Computer Assisted Drafting
- Crash reconstruction software for advanced mathematical calculations
- Digital photography and video
- Microscopy
- Gas Chromatography for chemical analysis
We pride ourselves on investigating the facts, properly interpreting them and correctly applying them to the analysis. Introtech has provided services in Florida, New York, Michigan, Illinois, Missouri, Kentucky, Indiana as well as Ohio for a wide variety of clients.
Working as a team, more than one investigator or reconstructionist are involved in a case. This team approach maximimizes the training and experience brought to any case and provides our own internal review of any opinion. As an added benefit of working as a team, if you call the office and the primary investigator is unavailble, the assisting investigators can usually answer any question or assist you.
Ultimate opinions expressed to a reasonable degree of certainty! Using techniques developed from years of experience, Introtech Crash Reconstruction provides highly accurate and honest answers. Founded in 1989, Introtech’s team of investigators, scientists and reconstructionists have over 200 years of combined on-scene experience in investigating all manner of transportation casualties. Introtech's capabilities encompasses many types of crash reconstruction categories such as:
(select category to view gallery)
By far the most common type of crash involves two or more vehicles were standard issues regarding speed, time, distance and avoidability need to be resolved. After a review of all documents and photographs, we usually visit the crash scene to document latent physical evidence and roadway geometry. If they are available, damaged vehicles are inspected to measure crush patterns and post-crash dimensions. We maintain a current listing of motor vehicle specifications and specifications to compare pre and post-crash differences. We conduct extensive research on the capabilities, specifications, technology and dimensions of each vehicle involved.
If necessary, within budgetary considerations, we often conduct experiments, test skids or reenactments to answer specific questions about the crash environment. We utilize advanced computer programs to perform simulations, assist in sophisticated calculations, and computer assisted drafting programs (CAD). Along with police measurements, we often conduct total station forensic mapping of the crash scene in order to draw detailed scale drawings of the after crash situation. Most crash reconstructions require an accurate scale drawing of the crash scene, roadway topography and geometry. Without an accurate scale drawing to evaluate the after crash situation, it is often not possible to properly conduct a crash reconstruction. The data collected along with the scale drawings are then analyzed to arrive at opinions that have proper foundation.
Watercraft and marine accidents pose a special challenge to an investigator. Usually there is very little evidence on the water itself and most of the evidence is contained in the damaged boats, objects struck and people's recollections. This category of crash requires highly spcialized understanding of vessels and the environment they operate in. Introtech is fortunate to have two retired U.S. Coast Guard officers (a Captain and Lieutenant), both of whom have vast experience and training in the field. In addition to experience such as officer of the deck, boarding officer, marine engineer, search and rescue controller, aircraft commander and small boat coxswain their training includes: 
- National Boating Safety School
- National Search and Rescue School
- Underwriters Laboratory Advanced Boat Accident
- Motor Surfboat School
- Emergency Medical Technician
- Marine engineering schools
- U.S. Coast Guard Academy
- Shipboard and aircraft fire fighting
- Damage control
- Marine propulsion training
In addition to the two retired Coast Guard officers, we are augmented by part-time watercraft investigators with experience in general marine investigations and law enforcement.
Introtech will determine the crash sequence of events and evaluate operator actions with respect to the rules of the road. We have conducted a number of both daylight and night time visibility experiments in the marine environment. Watercraft services have been performed in Ohio, New York, Indiana, Kentucky, Florida and Canada. In addition Introtech conducts training in watercraft accident investigation and reconstruction at various locations throughout the United States and Canada.
Commercial vehicle crashes tend to be unique and complex. We are able to thoroughly investigate these crashes by analyzing truck braking systems, engines, suspension systems, log books and more. Our staff is qualified and routinely conducts full Title 49 inspection of commercial vehicles. We are current on all laws pertaining to trucks including ICC, Federal and various state laws. Introtech has performed a number of 3D video animations to depict our opinions regarding truck cases. An ASE certified truck mechanic is on call when we need more in-depth mechanical analysis.
We have the hardware and software to download a wide variety if electronic data from diesel engine control modules (ECM). This valuable electronic data is then used to add to our knowledge of the crash sequence that is obtained through the usual evidence. Each year specific members of our staff attend advanced training in technology such as truck braking systems, modern trucking, Global Positioning Systems and electronic control modules.
Introtech has performed scores of on-site reenactments to determine vehicle dynamics and visibility factors including pedestrian visibility, acceleration/maneuvering ability, trailer underride issues and test skids. If necessary and appropraite, the results are then assembled in video or DVD format to document the experimentation or depict the results to a jury. Over the years, Introtech has performed many 3D animations to complement the data obtained through reenactments. The list of our animations has included heavy trucks, pedestrians, motor vehicle crash, boating accidents, industrial casualties and motorcycles. A fully documented experiment or 3D animation may be the most effective way to demonstrate an opinion.
Please contact us directly for a CD sampler of animations or experiments that have been sucessfully used in trial.
The final test of an expert's opinion is in the courtroom. Introtech takes great pride in our ability to present opinions in court. The jury must understand how an opinion is formed and how it relates to the causative factors in the crash. We have testified in courts throughout Ohio, Florida, Kentucky, Indiana, New York, Illinois, Pennsylvania and Michigan.
Today's juries have high expectations for technical application and sophisticated methods of presenting data. Television shows and movies have set very high expectations for forensic presentations. Our expert testimony is often complimented by 3-D animations, exhibit boards, power point presentations, modeling and other audi-visual aids. As a company, we have testified in over 250 trials with a very high success rate for our clients.
Depositions are a vital part of the litigation process. Part of the reconstructionists job is to assist you obtain as much valid information from the deponents as possible, whether they are witnesses, police officers or other experts. Introtech often provides drawings and vehicle cutouts for deposition purposes that are drawn to a size and scale necessary in addressing the pertinent issues. We focus on including enough detail from the scene so that the drawing is truly a representation of what is on the roadway. In some cases the deponent might look and see something in the drawing that triggers his memory. Notations, markings and identifications made on a scale drawing are of much better use to a reconstruction analysis than hand drawings that are not to scale on a sheet of legal paper. Once the deponent has made notations on a scale drawing, that data is of much better value to a forensic analysis than simply words or drawings that are not to scale.
Since 1988, Introtech has investigated and reconstructed over 4,000 accidents accurately and honestly. We pride ourselves on presenting an honest and thorough opinion with every accident reconstruction.
