Use this material to examine your own work. Confirm current requirements, forms and dates with ICE before applying.
Read ICE's requirement on the attribute page, then use the examples and self-assessment to examine evidence from your own work.
Questions for checking your evidence
Use these prompts to review commercial responsibility in your own work. They are preparation advice; the official attribute statements define the requirements.
- What budget did you control?
- How did the contract affect your decisions?
- Which commercial choice did you make, and what did it cost?
- What effect did your engineering decisions have on cost?
- How did you comply with statutory and procurement requirements?
Discuss any point you cannot yet explain with your mentor and identify the experience or record needed.
Participation, contribution, responsibility
| Situation | How it reads in this area |
|---|---|
| Participation | “I attended monthly cost meetings and reviewed valuations prepared by our quantity surveyor.” |
| Contribution | “I flagged that a subcontractor's drainage rates looked low compared with the others.” |
| Responsibility | “I compared the rates line by line, found the diversion item 40% below everyone else against a method statement that assumed the main was redundant, raised a formal tender clarification, and set the bid aside on a documented ground that would survive a challenge.” |
Illustrative and fictional. The most useful thing you can do with your own draft is read it paragraph by paragraph and decide which of the three each one evidences. Participation is worth very little on its own.
Describing activity, and demonstrating competence
Fictional: commercial
I was responsible for managing the budget for the scheme and ensuring works were delivered within the allocated funding.
The contractor claimed £42k for the extra dewatering. I read the ground investigation against their tender assumptions and concluded about half was genuinely a changed condition and half was their own sequencing. I offered £19k and set out which items I was accepting and why. They took it without going to adjudication.
The first is a duty. The second is a commercial judgement with a number, a basis for splitting it, and an outcome, and it shows the candidate reading the technical evidence to reach a commercial answer, which is the thing this area is really about.
What changes with the grade
At Incorporated level. Manage, prepare and control costs or budgets within your own area of responsibility, and use sound knowledge of the statutory and commercial frameworks that apply to it.
At Chartered level. The same statements, but evidenced at a scale and independence matching a Chartered role, and with an appreciation of commercial arrangements beyond your own. Understanding why your organisation chose that form of contract is worth more than describing what it says.
How evidence in this area usually fails to land
The job-description answer
Duties listed as responsibilities. It reads like a role specification, in the present tense of a permanent state rather than the past tense of things that happened.
How it sounds out loud. Recognisable by its tense and rhythm: 'I was responsible for managing the site team, liaising with the client, and ensuring compliance with…'. It sounds like a CV read aloud.
The repair. Convert each duty into one occasion where you discharged it and something turned on it.
Does this describe what you were employed to do, or what you did?
No outcome
The account stops at the action and omits the result. Add what happened, using a relevant measure such as programme, cost, risk, carbon, defects or service performance.
Does the account stop at the decision, or at the drawing being issued?
Everything rests on one project
One project (usually the largest or most recent) asked to evidence all seven areas, so several areas are covered by whatever that project happened to contain.
How it sounds out loud. Every answer returns to the same scheme. Reviewers eventually ask for something else, and the candidate who has prepared only one project has nothing in reserve.
The repair. Map examples against areas and find the ones resting on a single instance.
How many of the seven areas are evidenced from the same job?
An answer that fits several attributes and proves none
A broad account touching engineering, management, commercial and safety aspects at once, at a level of detail too shallow for any of them to be evidenced.
How it sounds out loud. The answer wanders. It sounds comprehensive and leaves the reviewer unsure what was just demonstrated, so they ask a narrowing question the candidate has not prepared.
The repair. Decide what each example is primarily for, and write it for that.
If you had to file this example under exactly one area, could you?
Questions to ask yourself
- You have described the design. What part of it was yours?
Am I reading about this candidate, or about their project?
- Who would have made that decision if you had been on leave that week?
Am I reading about this candidate, or about their project?
- What could you approve without asking anyone?
Was this person accountable for something, or near something?
- What was the largest decision you took alone?
Was this person accountable for something, or near something?
- 'Involved in': tell me what you did.
Did they take part, add something, or decide?
- What did you contribute that nobody else did?
Did they take part, add something, or decide?
- What made that difficult?
Did this require professional judgement, or just care and effort?
- Why could you not simply follow the standard detail?
Did this require professional judgement, or just care and effort?
- Why that value?
Do they know why that was done, or only that it was?
- What is that clause protecting against?
Do they know why that was done, or only that it was?
- What else did you consider?
Was there a real choice, and did they make it?
- Why did you reject that?
Was there a real choice, and did they make it?
- What happened in the end?
What happened, and did it matter?
- How do you know it saved that much?
What happened, and did it matter?
- What was the actual figure?
Could I check any of this?
- Which drawing was that?
Could I check any of this?
- Give me another example of that, from a different project.
Is this how they work, or the one time it happened?
- Is that how you normally approach it, or was that occasion unusual?
Is this how they work, or the one time it happened?
- How long had you been qualified when you did that?
Does this add up?
- That is a large saving on a scheme that size. How was it calculated?
Does this add up?
- Tell me about a time you had to raise something uncomfortable.
Is this understood, or recited?
- What did that cost you?

Where honest improvement stops
Alternatives and rejected options
Describe the alternatives you considered and why you rejected them. If there was no choice, say so and demonstrate judgement through another part of the work.
Was the problem demanding enough?
Describe the difficulty accurately. If the example gives little evidence of the required competence, choose another or seek further experience before applying.
Ethics, safety, sustainability and the public interest
Use an ethical example from your own experience. Ordinary actions such as checking, declining, escalating or correcting can demonstrate professional conduct without a dramatic dilemma.
Outcome, and why it mattered
Never invent or inflate a figure. An unsupported number is the easiest thing in a submission to test and the hardest to recover from, because it puts every other number you have written in doubt. If you no longer have the data, say what you can substantiate.
Participation, contribution, or decision
Describe participation accurately. If you did not make the decision, explain your contribution and what you learned, or choose another example to demonstrate responsibility.
Meaningful personal responsibility
State your authority accurately. Where your responsibility was narrow, explain the depth of the work within it. Sponsors countersign the account, and reviewers can question it.
A self-assessment you can fail
These are not things to tick because they sound right. Answer each one out loud. Anything you cannot answer is either a writing problem or a development gap, and those need completely different responses.
