A forensic case involved an allegation of defective minivan brake repairs. On a wet two-lane road, the minivan left the road while stopping, and impacted a telephone pole. The plaintiff driver’s complaints implied a dragging brake, and the plaintiff ’s expert reported a bent lower caliper bolt. This forensic investigation involved instrumented exemplar analysis of the effects on caliper drag that could be caused by a bent caliper bolt. The investigation methodology was chosen (in part) based on significant evidence spoliation on the part of the plaintiff ’s expert. This paper will also discuss the effects of the spoliation and resulting limitations on the scope of the analysis.

The Approach To Forensic Investigation Of A Medical Device Related Accident Differs From That For Consumer Products, Industrial Equipment, And Vehicles. Techniques For Investigating And Providing Case Assistance Related To Suspected Medical Device Incidents Are Presented, Including Essential Elements Of The Investigation, Investigative Techniques, And Information Resources On Device Failures And Standards. User Error Versus Design Defect Is Discussed, Along With The Causes Of Medical Device-Related Incident And The Mechanisms By Which They Cause Injury And Death. Since A Patient Is A Variable Biological System, It Must Also Be Considered That The Alleged Cause Of The Incident Was Not Attributable To The Medical Device.

The Influence Of Construction And Pile Driving Vibrations On Surrounding Buildings, Including Hospitals And Eye Examination Facilities, Sensitive Devices Such As Computers And Surgical Microscopes Or Electronic Machines, And People In The Urban Environment Is A Significant Consideration In Obtaining Project Approvals From Appropriate Agencies And Authorities. Implementation Of Construction Projects In Areas Adjacent To Existing Buildings (Aged, Historical, Residential, Commercial, Industrial, Medical Services, Or Electronic Services) Creates Additional Difficulties. Specialized Case History Is Presented Where Damage To Sensitive Structures From A Variety Of Vibratory Construction Methods Ranging From Pile Driving, Highway Construction, Rock Excavation And/Or Blasting, Was Considered. Twenty Homeowners From A Residential Subdivision In The Florida Panhandle, Claimed Damage Including Cracking To Their Properties During Construction Of Various Portions Of City Storm Water Treatment/Enhancement Project. It Was Also Alleged That During Excavation And Construction Of Drainage Structures, Especially Four Subsurface Treatment Vaults That Required Installation And Extraction Of Sheet Piles Using Vibratory Hammer, Stability Of The Nearby Residential Structures Was Endangered And Resulted In Movement/Cracking. Forensic Engineering Analysis Was Effectively Utilized To Identify, Investigate, And Remediate The Concerns As Well As Assist In Litigation And In Some Cases Avoidance. This Technical Paper Presents Some Legal Issues Related To Litigation, Mediation, And Resolution Involving Jurisprudence System And Introduces A Case History That Includes All Elements Of Forensic Engineering.

Lightning Is A Powerful And Dangerous Natural Force. It Is Capable Of Inflicting Significant Damage To Our Environment And Causing Injury Or Death In Living Organisms. Electrical And Electronic Circuits Are Particularly Susceptible To Lightning, Both From Direct Strikes And From Lightning Induced Electrical Surges. Fires Often Result From Lightning Strikes. Injury And Death Can Result From Both Direct Strikes, Lightning Induced Electrical Surges, And Indirectly From Structure Damage And Fires. The Insurance In-Dustry Offers Coverage For Lighting Related Losses And A Forensic Engineer Is Often Consulted To Assist In Adjusting The Claim.

The Impact

This paper examines the effect of a pedestrian inadvertently impacting a glass panel adjacent to a glass exit door. The glass panel was full length and unmarked, violating the local building code and building commissioner directives. The defense argued that the old building code, to which the college building was constructed, was “grandfathered” and there was no violation. Initial witness and plaintiff statements indicated that the plaintiff was running when he struck the panel, which shattered and caused the plaintiff to incur injuries. The plaintiff testified later, in deposition, that he was walking when he struck the glass. The court needed to establish liability percentage, which is common in civil cases, and it was necessary to determine at what pedestrian impact speed the glass panel would break. The analysis used Timoshenko’s theory of vibration plates, Roark’s stress strain formulas, ergonomics, and human factors to estimate the impact load and stresses on the glass panel that caused failure.
