Rooted in Community

At Bedrock Engineering, community is at our core. Serving both public and private sector clients in the San Joaquin Valley area and beyond, we strive to serve the community we call home. From topographic and boundary surveying, to construction staking, the preparation of maps, legal descriptions, and specifications; to underground utility locating/mapping, site planning, grading, street, and underground utility design, Bedrock Engineering is the Central Valley’s go-to engineering company.

Bedrock Engineering, Inc. is a state-certified small business, owned and operated by its founders: Corporate President Michael S.

With over ninety years of combined, local experience, Bedrock’s founders have been working together since 1990. Bedrock Engineering, Inc. is an active member of the San Joaquin Valley Chapter of ACEC, the American Council of Engineering Companies.

At Bedrock Engineering, we believe in hiring educated and highly talented individuals right from within our local community. Bedrock also believes firmly in giving back to the community by participating in local events and fundraisers, sponsoring local youth sports teams, being active in local clubs and professional organizations, and through donations, scholarships, and pro-bono work. The Central Valley is not just where we work – it is where we live, play, and raise our families.
