One of the two main contractors for the Highway 99 tunnel announced that it would appeal the Friday jury verdict, which rejected the company's $ 330 million charge against the state of Washington over the failure of the Bertha tunnel boring machine six years ago ,

Seattle Tunnel Partners (STP) has argued that a 110-foot steel pipe that hit Bertha on December 3, 2013 caused the collapse. This pipe was installed by the Washington State Department of Transportation during ground planning for the Alaskan Way Viaduct replacement project in 2002.

STP member Tutor Perini Corp., which has long had litigation, said in an announcement to investors that it "is disappointed with the jury's decision and will appeal the judgment in this case …"

The statement highlighted the finding of the 2015 project's three-tunneling dispute committee that the pipe was a "different site condition" for which the state was responsible for resolving or alerting the contractors. The board, whose views are non-binding, has not thought about how much damage the pipe has done.

During the trial at the Thurston County Supreme Court, WSDOT's attorney called the pipe "nothing more than a toothpick" for Bertha's massive knife head, while STP claimed the machine had made steady progress only three days after the pipe was opened.

In the run-up to the two-month trial, WSDOT lawyers uncovered documents showing that tunnel workers had found and logged the pipe prior to digging.

Tutor Perini submitted an official investor announcement earlier this fall, assuring him that his chances of winning on government or insurance funds were "both probable and reliably estimable" and that management had made its own confidential forecast of what the partners were saying about the Contract back of $ 1.44 billion will be paid back everything has been paid.

The four-lane tunnel was opened to traffic on February 4 and replaced the old Alaskan Way Viaduct. STP executives have not yet responded to Seattle Times comment requests.

The jury not only denied STP's claim, but granted the state $ 57.2 million from the contractors based on a 867 day delay while Bertha was exhumed and repaired from wet waterfront floors.

State Secretary of Transport Roger Millar said on Friday that he was awaiting an appeal so that he had not yet budgeted $ 57.2 million for other projects.
