A five million gallon above ground concrete tank failed in the City of Westminster on September 21, 1998. Our client performed a forensic investigation to assess the causes of failure.  As a part of the forensic investigation, Group Delta Consultants (GDC) performed a geotechnical investigation at the location of the failed tank and a similar tank still in operation.

Project Highlights :

• Our conclusions were that the failure was not related to soil conditions.  The client determined that the failure was caused by structural failure of the ring beam due to the corrosion of rebar.
• GDC completed the geotechnical investigation and report in a record time to meet aggressive schedule of MW report on the failure in 35 days
