Comprehensive investigation into the causes of the failure that led to the collapse of a concrete side panel
As chief technical expert for the Commission, SIMCO led a team of experts on the technical causes of the collapse of de la Concorde overpass
Comprehensive investigation and forensic analysis of the causes leading to major structural collapse
Concrete structures fail to survive their expected service lives because of the lack of the proper application of durability engineering by practitioners. Durability in its broadest sense depends on the nature of the concrete and the aggressiveness of the in-service environment.
Why do concrete structures fail? Why do they crack, delaminate, spall, or even worse, collapse?
SIMCO can help you to determine why these failures have occurred, assess the level of damage and analyze the impact of degradation mechanisms on the global performance of the structure under investigation.
SIMCO’s team of concrete experts is comprised of credentialed and experienced concrete engineering professionals who have provided superior consultancy and expert witness services to owners, engineers, architects, contractors, attorneys, manufacturers, and insurance companies for over 25 years.
Our team provides expert guidance and support in evaluating concrete deterioration problems, design issues, and construction defects.
SIMCO’s concrete and materials specialists have extensive experience and knowledge about materials science and they are highly-recognized experts around the world. SIMCO’s expert advisors provide professional and independent technical advice relating to all aspects of the material or the structure.
Our programs are designed to ensure a thorough investigation is conducted in the field and in laboratory in order to provide quality reports that are credible and that are supported with hard facts.
In the past few years, Dr. Marchand’s expertise was called upon by the offices of the Auditor General of Quebec, Ontario, Alberta and Canada. In 2003, Dr. Marchand acted as an expert in the coroner’s investigation into the collapse of the “Du Souvenir” overpass in Laval, Quebec. In 2006 and 2007, Dr. Marchand chaired the committee of experts appointed by the Public Inquiry on the partial collapse of the Concorde overpass.
Over the past ten years, Dr. Marchand has also been involved in projects in the United States. On behalf of the Deutsche Bank, he led the survey to determine the level of damage and the remaining life of the concrete foundations of the Bankers Trust Building, damaged by the collapse of the South Tower, of the World Trade Center, in New York City. His expert services were also used by the Department of Defense of the United States, including the Naval Engineering Services Center of the U.S. Navy.
