"WJE has investigated virtually every major structural collapse in the United States over the past five decades."
— Michael Koob, Senior Principal
WJE has participated in the engineering or architectural investigation of many of the United States’ most significant major failures and natural disasters since 1970 and has assisted in many investigations globally. Thousands of clients have relied on us to accurately determine the cause and extent of damage and repairs needed to restore their facilities to operation. Our experienced structural engineers, architects, and materials scientists have earned a reputation for quickly responding to catastrophic events, frequently arriving on-site the same day as a disaster.
WJE offers a full range of investigative, analytical, and laboratory techniques to determine the cause and extent of damage. Our extensive in-house laboratories and diagnostic field capabilities include a wide range of equipment and services for structural, architectural component, and materials testing. These resources enable our engineers and architects to better understand how structures and architectural systems respond to extreme events and to develop repairs and replacement systems that meet future performance expectations. We can also assist clients with recovery by providing temporary solutions that quickly return damaged structures to service.
