Tunnel Partners, which also includes Frank Coluccio Construction Co., Tukwila, Wash.; Mowat Construction Co., Kent, Wash.; HNTB Corp., Kansas City; and Spanish firm Intecsa, Madrid, submitted the favored best value proposal with a $1.09 billion bid plus technical credits that totaled 71,577,000, for a resulting best value score of 1,018,123,002, the Washington State Dept. of Transportation announced Dec. 9.
