Proven Construction Experts

Our safe, prompt, efficient, and fair construction practices have made us a valued partner, contractor, and employer.

Stacy and Witbeck is established in San Francisco. Our first signature project was the rehabilitation of the historic cable car lines in San Francisco.

We expand to Portland. In the years since, we’ve constructed the city’s entire streetcar system and multiple light rail and commuter rail lines.

The blue Portland Street car passes through a Portland street.

We start work in Salt Lake City and we’re still there! Since then, we’ve constructed over 135 miles of track in the region.

We expand to Washington! We have maintained our presence in the Evergreen State constructing and maintaining streetcar, light rail, and commuter rail systems.

We broaden our reach to the southwest, picking up our first job in Phoenix. We’re still actively building light rail, streetcar, and maintenance facilities in the area.

We won our first of many jobs in Denver, Dallas, and Houston, expanding our alternative delivery resume with these major CM/GC and design-build projects.

Modern Railway Systems joins the team as a wholly owned subsidiary specializing in signaling and communications.

We continue expanding with project wins in midwestern cities like Kansas City and Detroit. In the years since, the corridors in these two cities have experienced $9 billion in economic development.

We are awarded the $1.5 billion Mid-Coast Corridor Project in San Diego, our largest to date, and SANDAG’s first CM/GC procurement. Project completion reached in November 2021.

We continue our success in streetcar construction with a starter system in Oklahoma City.

We are contracted to rehabilitate the historic Pikes Peak and Manitou Springs Cog Railway, one of only two cog railways in the country!

Stacy and Witbeck celebrates 40 years. We are grateful to everyone who has contributed to our culture, growth, and success over the years.
