How to choose a structural engineer in Belfast
You need a structural engineer whenever load paths change: removing a wall, forming an opening, adding a loft floor, or building foundations near a neighbour. Building control will ask for their calculations.
- Check for chartered status with the IStructE or ICE.
- Ask whether site inspections and building control queries are included.
- Send the architect's drawings with your enquiry so the quote is for the real job.
- Ask how quickly calculations can be issued, as this often sets the start date.
- Confirm professional indemnity insurance cover.
