Jim has thirty-three years of experience in highway engineering and land development design and construction. His design experience includes: roadway, hydrology and hydraulics, and utilities.
Jim has performed design, field engineering and inspection for road, light rail and bridge projects. Most recently, he was responsible for the preparation of Highway Occupancy Permits (HOPs) for submission to PennDOT for land development projects. He performed geometric calculations, designed roadway and stormwater facilities, and developed traffic control and erosion and sedimentation (E&S) plans. He coordinated roadway design with traffic signal design, and prepared right-of-way plans and legal documentation for right-of-way acquisition and HOP permitting.
Jim has specialized expertise in horizontal and vertical roadway geometry; traffic signing and pavement marking; storm drainage design and stormwater management; PennDOT design, specification and construction procedures; and sanitary sewer collection and water distribution systems. His highway designs range from $23,000 local road improvements to $35 million Interstate Highway mainline and interchange design and rehabilitation projects.
Jim is a licensed Professional Engineer in Pennsylvania.

- Highway Construction – Expert Investigates Collision with Construction Vehicle
A driver was injured when her car collided with a construction vehicle on a state highway. The construction vehicle exited a work zone from a median crossover between the northbound and southbound travel lanes and entered directly into the passing lane in the southbound direction. The injured driver crashed into the back of the construction vehicle. Robson Forensic experts were retained to determine the cause(s) of the incident.
This case settled favorably for our client before trial.

- Construction Signage - Expert Investigates Single-Vehicle Crash in Work Zone
This single-vehicle construction work zone collision resulted in serious injury to a passenger. Liability was established against both the construction contractor and the construction inspection firm.
We determined that: the collision occurred due to the car traveling at high speed and the road surface changing from paved to dirt/gravel as a result of construction activity; the crash occurred within a long-term construction work site; the only construction sign encountered by the driver in his approach to the work site was a Road Work Ahead sign; the street where the work was underway was used as a “cut through” by non-local traffic; the persistent high-speed non-local traffic through the construction site was dangerous to both the construction workers and the traffic; the contractor and the construction inspection firm were aware of, or should have been aware of, the speeding through-traffic prior to the collision, but made no change to the traffic control plan. Based on the facts and in accordance with standards for work zone traffic control, our expert opined that the contractor and the construction inspection firm: should have taken effective steps to detour the non-local traffic; and that the failure of the contractor and the construction inspection firm to employ reasonable and established measures to effectively close the street under construction to through traffic was improper and a substantial cause of the collision and resulting injury. The case settled during mediation.

- In 2007 Motor Vehicle Collisions Resulted in Excess of 40,000 Fatalities
In 2007 motor vehicle collisions resulted in excess of 40,000 fatalities
and almost 2,500,000 injuries, according to the National Highway
Traffic Safety Administration’s website. It is often important to
determine both how a crash occurred and the underlying causes
of both the crash and resultant injury.
