Speaker Bio

Dr. Hunt specializes in damage assessments and failure investigations of residential, commercial, and industrial structures. He has evaluated damage to steel, concrete, masonry, and wood-frame buildings as well as to other structures, including parking garages, bridges, retaining walls, tanks, and industrial facilities. Dr. Hunt has investigated structures damaged by earthquake, wind, fire, snow, blast loading, water intrusion, earth movement, and material degradation such as wood decay and steel
corrosion. He has also evaluated claims of construction defects, design errors and deficiencies, and building code compliance issues on structures under construction and in service. Prior to joining Exponent, Dr. Hunt was a researcher at the University of California, Berkeley, where he investigated the seismic response and repairability of precast concrete cladding systems. Dr. Hunt is active in the earthquake engineering research community. He currently serves on the Earthquake Engineering Research Institute's Board of Directors for the Southern California Chapter and on the Learning from Earthquakes Executive Committee.

Dr. Marquez specializes in the evaluation of buildings and other structures considering the effects of extreme loading such as earthquake and impact. He has investigated the performance of existing structures, including evaluation of the root cause of existing damage to concrete, steel, masonry and wood structures, and he has proposed retrofit design solutions to address strength and serviceability issues. Prior to joining Exponent, Dr. Marquez was a senior engineer at Saiful Bouquet Engineers where he worked on various projects involving reinforced concrete and steel design for various building design types (e.g., airports, offices, and retrofits). Dr.
Marquez was also an instructor and researcher at the University of California, San Diego, where he developed a robust numerical model capable of capturing the nonlinear behavior of seismic protective devices under extreme loading and studied the implications of this behavior on building performance.

Structural failures and disputes on construction projects often leave owners, engineers, contractors, and the general public questioning “How?”, “Why?”, and “What went wrong?” Answering these questions requires detective work, technical analyses, and engineering insight. In this talk, the presenters introduce the world of forensic engineering and consulting. Case studies of a couple of recent projects will be discussed, including those that involve claimed design errors/omissions, defects, and
construction sequencing issues.
