In this article they mention Bechtel Group and Kiewit Group. I'm not familiar with the industry though so maybe some others will have better insight.
Ninja edit: Both of the aforementioned companies are private but I'm guessing there's some good public ones who stand to benefit, or manufacturers of tunneling equipment
