Mr. Lasater has devoted his career to the study of how buildings and building components respond to people, weather events, earthquakes, fires and explosions, temperature and humidity, adverse soil conditions, and other natural and man-made forces. He has decades of comprehensive construction, architectural, structural, and civil engineering experience.   From 1982 to 1995, he designed and constructed buildings and other facilities with the U.S. Navy’s Civil Engineer Corps, and was first introduced to forensic engineering following the 1994 Northridge earthquake.  He has since conducted more than 4,200 forensic investigations to determine the cause and extent of damages to building superstructures, foundations, finishes, roof surfaces, cladding, and fenestrations which have been subjected to a wide variety of perils, for which he has also designed, detailed, and specified measures for remediation.
