Construction Materials Intelligence
A monthly material-risk system using Stats SA CMPI/CPAP/CIPI data to detect unusual movement, volatility and divergence across road, concrete, steel and other civil-engineering inputs.
- Decision
- Prioritise which input risks need procurement, contingency or commercial attention without exposing project monetary values.

What I did in this project
Defined the question.
Prepared the data.
Built the analysis.
Validated and documented the result.
Prioritise which input risks need procurement, contingency or commercial attention without exposing project monetary values.
Construction inputs do not move together. A project team needs to know which material groups are creating unusual escalation pressure now, how abnormal that movement is relative to history, and which exposure deserves attention first.

What I changed before calculating anything
Worked calculations — not black-box KPIs
What the drill-down adds
The headline chart gives the decision signal. These additional views show whether the same conclusion survives when the data is sliced another way.
The question and method are documented, but unfinished results are not presented as completed analysis.
What I would say in the management meeting
What I would do next
An index is a market signal, not a supplier quotation. Exposure scenarios are illustrative percentages, not confidential project data.
