Who We Are

DeMarr Engineering provides a level of service and insight that enhances traditional land surveying, arborist, and civil engineering practice. We take a hands‑on approach that bridges field experience, design expertise, and constructability from the start of every project.

With extensive experience navigating local jurisdictional requirements and the practical construction insight gained through our affiliation with DeMarr Construction, LLC, we offer a unique, integrated perspective on civil engineering and construction projects.

Our engineers and technicians actively participate in fieldwork, including the collection and interpretation of survey data. This direct involvement allows our design team to develop a first‑hand understanding of existing site conditions before design begins; ensuring smarter decisions and fewer surprises later in the process.

Each project is supported by an in‑house, multidisciplinary team of six professionals who integrate practical construction knowledge, engineering judgment, and internal peer review. This collaborative approach strengthens design quality and improves coordination across all phases of work.

The result is a design process that delivers technically sound, constructible solutions that perform as intended in real‑world conditions. This depth of expertise, reliability, and continuity is often unavailable through solo practitioners and ensures projects are designed efficiently, reviewed thoroughly, and supported from initial survey through construction.
