Use this material to examine your own work. Confirm current requirements, forms and dates with IStructE before applying.
The minimum standard is Experience for both Incorporated-Member and Chartered Member.
What strong and weak evidence look like
Look for
- A design change you made because of how it would be built.
- A temporary condition you identified that governed the permanent design.
- A site problem you were called to and resolved, with what you decided.
- A construction sequence you thought through, including the stage that was most vulnerable.
- Evidence of tolerance, setting out or fit being designed for rather than discovered.
Watch for
- Site visits with photographs, and no decision attached.
- "I attended site meetings."
- A design with no evidence that anyone considered how it would be erected.
- Treating buildability as the contractor's problem.
Portfolio items that tend to work here
Suggestions, not a required list. What matters is that the item is yours, that it is annotated, and that it demonstrates the standard rather than the subject.
Questions to ask yourself
- What is the worst stage during construction?
The temporary condition governs far more often than candidates expect.
- What did I change because of how it would be built?
That change is the evidence. Awareness of buildability is not.
- Have I been on site for my own design?
Engineers working mainly in a design office may need further opportunities to demonstrate construction experience.
The same objective, in different kinds of work
| Setting | What the evidence tends to look like |
|---|---|
| Designer | Changing a detail so it could be built without working at height, and recording what remained. |
| Site engineer | Sequencing a pour or a lift, and holding the line when the programme pushed back. |
| Temporary works | Designing or checking a propping scheme, and setting what had to be verified before load was applied. |
Illustrative. The objectives are written to be met in a range of ways by anyone practising as a structural engineer.
How reviewers tend to approach this objective
- Asking how your structure was erected, stage by stage.
- Asking what the crane could and could not reach.
- Asking what went wrong on site and what you did.
- Asking about tolerances and what happens when they accumulate.
There is a bank of original practice questions in the interview question bank, filterable by objective and by grade.
