A “Measurement” in Time


Since 1961, the engineers and field crew at DJS Associates, Inc. have utilized the most state-of-the-art technology in our investigations. Our commitment to our clients to stay up-to-date on the latest technology for collecting, analyzing and demonstrating data continues with the purchase of two (2) Leica RTC 360 scanners and the BLK 360 scanner. The recent investments have led to a trip down memory lane, where we looked back at how the methods of collecting data have changed over the years. Stories were shared of equipment breaking, inspection bloopers, and most importantly the monumental projects taken on by our team. To commemorate the newest purchases, and the exceptional work that has been done to date, we have created a timeline of our technology over the years. Enjoy!

3D Animation: Difficulties in Transport

Hugh Borbidge, BSME, Director of Engineering Animations ::::

At the request of our client, DJS Associates was asked to demonstrate the spatial relationships between a worker and a vehicle. Specifically, DJS Associates was asked to show, to-scale and in 3D, how a telehandler (vehicle) came into contact with a tagline worker who was part of a two-man crew helping to transport a 40-foot steel column.

In this case, the telehandler vehicle had to stop quickly which resulted in added forward motion to the 40-foot column being transported. As a result of the added forward motion to the transported column, the rear tagline worker was pulled forward into the path of the telehandler vehicle. The to-scale, 3D demonstrative exhibit demonstrated that as the telehandler vehicle resumed its forward motion, the front right tire contacted the tagline worker before he had a chance to clear the hazard area.

Two Collision Contributors, One Code Violator

Robert T. Lynch, PE, Senior Collision Reconstruction Engineer ::::

A motorcycle traveled across the double yellow centerline into the opposite travel lane on a rural, two-lane roadway in order to pass a farm tractor. When the tractor turned left at the intersection a collision occurred. DJS Associates was retained to evaluate the matter to determine the contributing factors that led to the subject incident. The incident would have clearly been avoided if the tractor operator hadn’t turned left or if the motorcyclist decided not to pass the tractor at the intersection. So, in general, the actions of both operators could be considered as contributory. However, a review of the (Pennsylvania) state statutes indicated that the actions of the motorcyclist were in violation of the vehicle code while the tractor operator’s actions were in compliance with the vehicle code

The vehicle code requires that a left-hand turn be completed from the left-most lane available, and that the driver of a vehicle intending to turn left at an intersection yield the right-of-way to any vehicle approaching from the opposite direction which is so close as to constitute a hazard. From an engineering perspective, the actions of the tractor operator to turn left at the intersection from the travel lane were in compliance with the vehicle code.

Average Grades, Exaggerated Life-time Losses

Mark L. Heckman, MEd, CRC, LPC, Vocational Employment Consultant ::::

Brandon, a young man, was injured in the hospital examining room during the course of being treated for a concussion that he had sustained while playing basketball as a senior in high school. Two days after the basketball game he was treated at West View and fell face forward while being examined, sustaining a traumatic brain injury, facial fractures, and damaged teeth. Brandon alleged that he would potentially lose the income difference between a Physician (about $220,000/yr.), his pre-accident goal, and a Physical Therapist (about $90,000/yr.), his current major.

Initial review of hundreds of pages of medical, neuropsychological testing, school, and legal documents and records was completed. Records were thoroughly summarized and contained in the initial section of the expert report. Brandon’s pre-accident medical history, which included 4 previous sports-related concussions, fatigue symptoms, a prescription for Percocet, and several orthopedic injuries was also documented in the expert report. Also documented were the differing opinions of the treating Neuropsychologist and Independent Evaluator that the hospital retained. While the treater felt that Brandon had a neurocognitive disorder related to the fall in the hospital examining room (the basis of the lawsuit), the latter opined that Brandon did not give full effort on the tests he administered now, 4 years after the incident, and that his scores were worse than severe TBI patients and those with dementia, mental retardation, and did not fit the circumstances of the accident.
