Civil vs. Structural Engineer: Who Do You Need?

When planning a construction or development project, knowing which engineer to hire can make or break your timeline and budget. While civil engineers and structural engineers often collaborate, they serve distinct roles that impact different phases of a project.

So—civil vs. structural engineer: who do you need?
Let’s break down the difference so you can hire the right expert for your project.

What Does a Civil Engineer Do?

Civil engineers focus on site development and infrastructure. They design the physical layout of land, roads, drainage, utilities, and grading. If your project requires site planning, permits, stormwater systems, or utility connections, a civil engineering company like RSP Engineers is essential.

A civil engineer typically handles:

  • Site layout & grading

  • Stormwater management plans

  • Drainage design

  • Roadways & driveways

  • Water & sewer utilities

  • ADA compliance

  • Permitting coordination

What Does a Structural Engineer Do?

Structural engineers ensure buildings and infrastructure are safe and stable. They analyze and design load-bearing components such as foundations, beams, columns, and framing systems.

A structural engineer typically handles:

  • Foundation design

  • Beam and column sizing

  • Structural framing (steel, wood, concrete)

  • Load calculations

  • Reinforcement specs

  • Structural inspections

If your project includes multi-story buildings, retaining walls, or custom foundations, you likely need a structural engineer in addition to civil services.

When Do You Need Both?

Many projects—especially residential, commercial, or mixed-use developments—require both types of engineers.

For example:

  • A civil engineer designs your stormwater plan, site grading, and utility layout.

  • A structural engineer designs the foundation and framing for the building itself.

Hiring a team that understands how these services overlap can streamline your project and avoid costly conflicts between site and building design.
