Value engineering studies
Compare design alternatives on function, cost and weighted criteria — with an audit trail.
Live demo
A simplified, self-contained version of the core idea. Everything runs in your browser with sample data.
| Alternative | Cost £ | Value | V/C |
|---|---|---|---|
| Baseline: blockwork wall scores 6 / 8 / 5 / 4 | 5.95 | 1.24 | |
| Option A: steel-frame + board scores 7 / 6 / 9 / 6 | 7.10 | 1.80 | |
| Option B: CLT panel scores 8 / 7 / 8 / 9 | 7.90 | 1.50 |
Recommendation: Option A: steel-frame + board. Δ vs baseline: value +1.15, cost −£8,500.
V/C = weighted value per £10,000. Every weight change is stored as a new version.
The problem
Value-engineering workshops end in spreadsheets that nobody can re-check. Weightings change and the reasoning behind a decision is lost.
Our solution
A Django and Next.js app for value studies: requirements that are challenged, function and cost capture, versioned criteria weightings, baseline-versus-alternative comparison, value-to-cost ratios and economic formulas, and a report export with traceability.
- Versioned weight sets
- Weighted value and value-to-cost ratio
- Recommendations with baseline deltas
- Optimistic locking and audit trail
Result
First-release scope implemented, including the portfolio dashboard and study prioritisation.
