Expertise

Engineering relies on shared knowledge and experience, particularly in underground construction. That’s why we’re so active in publishing and speaking, sharing what we’ve learned from our latest projects.

This is one way we help keep the industry growing—by sharing our experience so that others can build on it. Our best work, we believe, makes meaningful contributions to the industry.

The case studies offered here provide only a sample of the important projects we have worked on. We’ve pulled from decades of experience and have highlighted a few of our specialties, including contract provisions, cost estimating and scheduling, and design methodologies.

You’ll find many articles on complex underground projects, from contingency planning for microtunneling to the use of pressure face tunnel boring machines (TBMs). We’ve also included an exploration of the Napa Valley wine caves, a history of San Francisco tunnels, and a discussion of the need for fair contracts, as evidence of our evolving expertise and pride in our work.

We appreciate your interest in what we’ve shared here. Your thoughts and comments are always welcome.
