With a long history of successful projects extending throughout Northern and Central California, Siegfried understands the unique needs facing our clients. We work closely with architects, design-build firms, and both private and public entities to produce the most appropriate solutions to any civil engineering challenge.

When you need sound structures built on solid design, Siegfried delivers. Our expertise in structural design and coordination is based on over 60 years of engineering buildings and related structures. Our clients rely on our ability to balance deadlines and budgets with the design insight required for structural work.

When the stakes are high, both private developers and public agencies turn to us for reliable results the first time. At Siegfried, technology drives these results, whether we’re linking to systems by satellite, to clients across the country, or to team members in the field.

Starting from the ground up is where the Siegfried Geotechnical Engineering team is at its best. From field explorations, lab testing of soils, and geotechnical engineering analysis, to construction services and investigation reports – we have the depth to service a multitude of public and private projects.

At Siegfried, we combine the art and science of landscape architecture to create memorable and enduring outdoor spaces. Our designs seamlessly blend softscape and hardscape elements by responding to natural land features that are ultimately user-focused and fulfill our client’s vision.

Different projects have different needs, and Siegfried provides Partnering services for our clients to close the gap on your build. What are Partnering services? Public outreach, meetings with the community, and grant writing are a few ways our team can not only build your project, but tell the story too.
