Unlike many firms of our size, Firma Design Group includes both landscape architects and civil engineers. We understand that these professions are interrelated on every project, and this holistic philosophy informs everything we do - from the initial client meeting to the last day of construction. Our team members connect and integrate the two disciplines and coordinate all other resources necessary.

A principal is intimately involved in each project - this one-on-one relationship enables us to fully understand each client's unique goals, and is integral to our successful design process. We place the highest value on excellent communication with our clients so that the final results exceed your expectations.

Tom Billeter was extremely helpful, straightforward, knowledgeable, and very trustworthy. Can't really say enough good about my interactions with the firm and particularly with Tom.

BC Engineering was involved in every step of the planning, permitting and construction of our engineered septic system. We have a relatively complex set of challenges, and it was a pleasure to work with them to arrive at a system that met our needs for capacity given the size of our house and also was permitted in a timely manner. I would highly recommend Jessica, Jonathan and their team.

The ADU firm I work for has hired BC Engineering for several projects throughout the Northbay and each time they provide us with prompt, professional service. We have come to depend on them and even made BC Engineering a preferred engineering vendor. More importantly, their staff treats our customers to the same high standards we expect of our own team members. **Highly Recommend**

Both my son and I have used BC Engineering Group for multi-million dollar residential projects. With all construction-related firms busy with fire rebuilds along with their normal workloads, it's refreshing to work with an organization that is responsive and communicative. They return calls and texts immediately, even after hours. I would place them at the top of the list of firms we've worked with in the past 5 years. They will approach your project as if they are a partner.

I used BC Engineering recently and am VERY pleased with their service. In applying for a grading permit with the county we ran into some points of disagreement with the fire department. BC Engineering's handling of the situation was both professional and effective. Their staff is both knowledgeable and responsive. I highly recommend them!

Great bunch of people, and always willing to help out! I have relied on Marcel Delagnes, on many occasions, to help answer questions from clients and fire victims regarding fire debris removal, septic system regulations, drainage, grading, and the list goes on. They offer many professional services for fire victims to help them start on rebuild projects

BC Engineering Group is THE septic company to use. As a Realtor, we only work with quality inspectors as that's what our clients expect. That's why we only use BC Engineering for our septic inspections. Easy choice.
