Tunnel Construction Engineering Services

Working under pressure

Tunnel construction is a complex process involving multiple disciplines. At Stiver Engineering, our structural design services cover the bases from end to end.

Our professionals are veterans in tunnel design—you name it, we’ve tackled it. We’ve engineered tunnels in major cities and major universities. The work examples in our portfolio illustrate the breadth of our experience in structural design, including with tunnels.

In addition, Stiver’s construction engineers are adept at designing access shafts for your underground facility or workspace. It’s critical that access shafts be designed safely and built to last, and our structural design professionals know how to get it done. We analyze all the conditions to design the ideal access shaft for your project.
