Interface Consulting Testifies in $667M Win for Energy Transfer

Chris Sullivan Acts as Expert Witness in Dakota Access Pipeline Case

Interface Consulting International Inc., a B. Riley company, announced that Chris Sullivan's expert testimony supported Energy Transfer's claims that the company incurred additional unplanned construction costs due to the violent protests and vandalism against the Dakota Access Pipeline.

Interface Consulting was engaged to review the various change orders agreed to between Energy Transfer and their pipeline construction contractors as well as quantify the additional construction costs due to the Dakota Access Pipeline protests. In the end, Interface Consulting's team was able to identify $14.6 million in additional construction costs.

It was concluded that damages stemmed from the cost to repair vandalized construction equipment and pipeline components, contractor standby charges, contractor move around costs, the cost for additional fencing, and the cost of hiring additional security personnel.

"I'm proud that our efforts helped achieve a favorable result, ensuring our client was fairly compensated for the significant impact these challenges had on their project," said Chris Sullivan. "Our thorough analysis and testimony enabled us to present a clear and compelling case to the court that supported our client's claims."

"This case underscores the critical role of meticulous analysis in complex construction disputes," said Ian Ratner, CEO of B. Riley Advisory Services. "Our team's detailed review of change orders and quantification of additional costs allowed us to clearly demonstrate the financial impact of delays and disruptions."
