PRACTICE PROMPT
Use this fictional setting to practise clear reasoning. It is not an assessment or institution paper.
The setting
A structure of 900 tonnes with a mixture of steel frame, concrete cores and concrete slabs.
Your task
Estimate the A1–A3 embodied carbon by element.
What a useful response would show
Mass times factor, with factor sources stated and the total sanity-checked per square metre.
Reflect afterwards
- What assumption mattered most?
- What would you check before using this on a real project?
- Could another engineer follow your recommendation?
