Free Engineering Firm Org Chart Template
An engineering firm typically organizes by discipline: Structural, MEP (Mechanical, Electrical, Plumbing), and Civil each have their own Principal Engineer and team. A Managing Principal sits above the discipline leads. Project Engineers run individual projects across disciplines.

Frequently asked questions
How is an engineering firm structured?
Most firms organize by discipline: Structural, MEP, and Civil each have a Principal Engineer leading the team. A Managing Principal sits above. Project Engineers run individual projects and pull resources from any discipline as needed.
What is the difference between a principal and a project engineer?
Principal Engineers own a discipline (Structural, MEP, Civil) firm-wide and the team that delivers it. Project Engineers own one project at a time and pull discipline expertise from the Principals' teams.
Should small engineering firms have separate disciplines?
Below 10 engineers, most firms specialize in one discipline (often Structural or MEP) and partner with peer firms for the others. Above 10, breaking out internal MEP usually starts to pencil.
