Inclusivity breeds bold, creative solutions.

About Us

Founded in 1954 and incorporated in 1956 as Jacobs Associates, Delve Underground is strongly tied to its roots in practical, cost-effective, and innovative construction engineering.

We are solutions-oriented consultants, with a culture that emphasizes quality and responsiveness. We like to “get our boots dirty” meaning we know that practical and constructable solutions come from experience with the construction process.

Our staff are experts in one or more disciplines that are needed to execute heavy civil project design and construction: structural engineering, geotechnical engineering, site civil engineering, architecture, mechanical engineering, engineering geology, hydrogeology, construction management, and construction claims consulting.


We solve our clients’ infrastructure challenges with our collective expertise and legacy of underground excellence.


To provide fulfilling opportunities in a collaborative and inclusive workplace that inspires bold, responsive infrastructure solutions.


We help build thriving communities by delivering state-of-the-art, sustainable heavy civil infrastructure.
