SEATTLE — The contractors building the Seattle tunnel have asked the state for an extra $12 million.
KIRO-TV reported that Seattle Tunnel Partners filed a request for the funds in November. The change-order letter, obtained by KIRO through a public records request, alleges that when the contractors started digging a rescue pit to reach the broken-down tunnel machine called Bertha, they found conditions that were different than the state led them to expect.
Those conditions led to extra work.
The request is the first one related to the construction of the rescue pit.
The Washington State Department of Transportation says the request is under review.
Last month, state officials told lawmakers they denied 77 percent of the $210 million in change orders the contractors have requested.
