Use this material to examine your own work. Confirm current requirements, forms and dates with IStructE before applying.
The minimum standard is Experience for Incorporated-Member and Ability for Chartered Member. Concept Creation and Design is the only objective where the grades require different standards.
What strong and weak evidence look like
Look for
- Two different arrangements you compared, with the reason one was chosen.
- A sketch showing the load path, drawn by you at the time rather than reconstructed afterwards.
- A stability strategy you set, and what would have happened without it.
- A concept that changed because of carbon, cost or buildability, with the before and after.
- A decision on a transfer, a movement joint or a grid that had consequences you can describe.
Watch for
- Describing the scheme that was built without saying who chose it.
- "The project used a reinforced-concrete frame": a fact about the project, not about you.
- Options that differ only in member size or material, which is not a real comparison.
- Concept work presented with no sketch of your own anywhere in the portfolio.
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
- Which arrangement did I choose, and what did I reject?
A concept with only one option in it is not a decision.
- Can I draw the load path for my own project, from roof to ground, without notes?
Reviewers ask for exactly this, and it is where thin concept evidence shows.
- What holds it up sideways?
Stability is the fastest way for a reviewer to find out whether you understood the scheme or inherited it.
The same objective, in different kinds of work
| Setting | What the evidence tends to look like |
|---|---|
| Buildings | Setting a grid around an awkward transfer, and choosing between flat slab and beam-and-slab on more than span alone. |
| Bridges | Selecting a deck form and articulation, and understanding what the bearings and the abutments are being asked to do. |
| Existing structures | Deciding what the existing frame can be asked to carry, and where new load must go around it. |
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 you to sketch the structure and its load path, live.
- Asking what the second scheme was, and why it lost.
- Asking what you would change if the grid moved, or a column had to go.
- Moving from your project to a fundamentals question about stability or robustness.
There is a bank of original practice questions in the interview question bank, filterable by objective and by grade.
