When you need a structural engineer

Practical triggers for hiring structural engineering — openings, additions, foundations, and safety concerns.

Start your projectBrowse professionals

Structural engineers design how buildings stand. If loads change or the ground is unreliable, architectural intent alone is not enough.

Common triggers

  • Removing load-bearing walls
  • Adding floors or heavy roof loads
  • Foundation settlement or underpinning
  • Large openings in exterior walls
  • Decks, balconies, and retaining structures needing stamps

How they work with architects

Often as consultants. On narrow scopes you may hire structural directly. Clarify who coordinates and who submits to the city.

What to request in a structural quote

Deliverables (calcs, drawings, stamps), number of site visits, revision policy, and assumptions about existing conditions.

Do not wait for a failure

If you see sudden cracks, doors jamming, or movement, seek qualified assessment promptly.

FAQ

Is a contractor’s beam size enough?
For permitted structural changes, jurisdictions often require licensed engineering. Rules vary — verify locally.
Can one firm do architecture and structure?
Some multi-discipline firms do; others partner. Either can work with clear roles.
