Forensics Exhibit Illustrations

  1. 1. Engineering Forensics Illustrations<br />For the following selected exhibit illustrations I created a variety of CAD generated 3D and 2D images. These images assisted the engineering forensics consultant in clearly illustrating his conclusions to non-technical members of the court and legal teams.<br />Case ‘A’ - $500M fire and explosion in a semiconductor manufacturing Plant<br />Case ‘B’ - Class action lawsuit alleging health issues from expose to hazardous chemicals due to improper industrial ventilation and local exhaust systems. This lawsuit involved several semiconductor manufacturing facilities at multiple locations. I’ve included 3 of the buildings as examples.<br />
  2. 2. Case ‘A’<br />These selected exhibit illustrations were created from insurance photographs, engineering drawings, and the forensics consultant’s sketches. The use of 3D & 2D CAD allowed for the accurate recreation of this facility prior to the incident and to clearly illustrate the complete exhaust systems with the fire source and extent of system damage<br />Software utilized: <br />AutoCAD Architectural & Building Systems<br />
  3. 3. Composite Exhaust System 3D IllustrationShows the routing of all process exhaust systems from the cleanroom to the scrubbers/fans on the roof.<br />Acorn Consulting Services, LLC<br />Client:<br />
  4. 4. Acid/Toxic Exhaust System IllustrationShows the routing of acid/toxic exhaust system from the cleanroom to the scrubbers on the roof. The source of the fire was in this system and is outlined on the illustration.<br />Acorn Consulting Services, LLC<br />Client:<br />
  5. 5. Acid/Toxic Exhaust System Damage IllustrationShows the routing of acid/toxic exhaust system from the cleanroom to the scrubbers on the roof. All equipment and exhaust duct damage shown in light gray.<br />Acorn Consulting Services, LLC<br />Client:<br />
  6. 6. Return Air Building Level - Exhaust System Damage IllustrationShows the relation of the exhaust systems and the structure at the level the fire started. All equipment and exhaust duct damage shown in light gray.<br />Acorn Consulting Services, LLC<br />Client:<br />
  7. 7. Return Air Building Level - Photo Location IllustrationShows the location and direction for each insurance company photo used to created all illustrations.<br />Acorn Consulting Services, LLC<br />Client:<br />
  8. 8. Composite Exhibit Of Multiple Illustration Styles<br />The 3D & 2D illustrations from the source of the fires were shown with a photograph as an example of the clarity the CAD illustrations offered.<br />Acorn Consulting Services, LLC<br />Client:<br />
  9. 9. Enlarged 3D IllustrationShows more detail for the location of the fire source. This view places all interconnected process/support equipment and exhaust ducts associated with the fire. Both wire frame and solids modeling were used for this illustration.<br />Acorn Consulting Services, LLC<br />Client:<br />
  10. 10. Alternate Enlarged 3D illustrationThis illustration is a simplified example of the prior one. The exhaust systems and process equipment have been shaded in color for additional clarity.<br />Acorn Consulting Services, LLC<br />Client:<br />
  11. 11. Case ‘B’ - Building 1<br />The following selected exhibit Illustrations were created from engineering drawings from the time period of the case and the forensics consultant’s sketches. <br />The plaintiff worked in two rooms within this building. Their legal team claimed the HVAC systems were simple and inadequate. The 2D plans clearly show that each of the suspect tools in these areas were exhausted and that each area had separate and sufficient HEPA filtered air supply. The sections show the interrelationship of the systems, work areas, and equipment. The 3D images allowed for a clearer illustration of the complex HVAC systems in a more familiar context for a non-technical audience.<br />Acorn Consulting Services, LLC<br />Client:<br />Created with AutoCAD Architectural/Building Systems<br />
  12. 12. Composite HVAC Systems 3D Illustration Shows all HVAC equipment and ducts for both rooms.<br />Acorn Consulting Services, LLC<br />Client:<br />

  22. 22. Case ‘B’ - Building 2<br />The following selected exhibit Illustration examples were created from engineering drawings from the time period of the case, and forensics consultant’s sketches. <br />The plaintiff in this building worked in multiple process bays adjacent to each other. These were illustrated together to show their relationship with the HVAC systems for each. The 2D plans clearly show the systems of each level. The sections show the interrelationship of the systems, work areas, and equipment.
