Our Projects

The Civil Engineering profession is more to us than just drafting plans and obtaining permits. We take pride in our work and in the projects we work on as they are our productive achievements and lasting legacy of our life's work. It's our passion and purpose to make society a better place by providing our civil engineering services. We blend new homes and additions in with their surrounding topography and help architect's create more livable space in an environmentally sustainable way.


Showcased below are just a few of the many projects we've worked on. In all of these cases, we contract directly with the property owner as the owner of the property has the most invested and needs to be protected with a direct contractual relationship. The one exception to this rule; we will contract under select architects if we have an ongoing working relationship.

Take a look at our past projects below and their corresponding pages in more detail. If you are thinking about a similar project on your property, feel free to contact us by phone or email to talk about your project goals. If we are a good fit, we will aim to provide a proposal within 24-hrs of your request for proposal (RFP). If not, we will be sure to recommend another firm that is better suited for your needs.

We designed the placement and elevations of this new home in McLean, VA along with storm water controls, erosion controls, utility and grading design.
