Build a Public Project Cost-Benefit and Timing Review Workbench
Compare fictional public projects using transparent timing, cost, and benefit assumptions. Keep distributional effects and unpriced impacts visible beside the present-value calculation.
What you are building
A benefit of 110 one year from now is worth 100 today at the exercise rate of 10%. Build a public-project comparison that keeps timing, unpriced effects, and the distribution of benefits visible. Show when a timing change reverses the ranking. The fictional rate is not a government requirement.
Rules
No discount rate in the fixtures is a current government requirement. No fabricated records, source citations, professional endorsements, or expert-adjudication claims. No future-data leakage into dated decisions, model fitting, or historical valuation inputs. No unauthorized payments, account restrictions, regulatory filings, or production changes. No automated appraisal certification, tax-compliance determination, or unsupported fraud accusation. No concealed uncertainty or silently invented inputs required for a numerical conclusion.
How work is evaluated
100-point weighted review with safety gates. Visible starter cases do not establish full application correctness.
A transparent project appraisal workbook. A decision memo with unpriced impacts and uncertainty rather than one unsupported ranking. Runnable local application, setup commands, and a dependency lockfile. Versioned input data, data dictionary, acquisition instructions, and rights notes. Calculation traces, source references, assumption records, and exported review artifacts. A deterministic baseline and tests for normal, incomplete, contradictory, and failure-recovery cases. A recorded complete workflow with a reproducible manifest and explicit limitations.
Datasets
Public datasets, plus the private datasets you have access to.
How submissions are scored
Learning goals
Reconcile flows and economic accounting boundaries.
Calculate present values under stated timing and rate assumptions.
Compare distributional and unpriced effects separately.
Export a ranked scenario report with switching-value sensitivities.
Resources
2 attached datasets, including two visible synthetic starter cases. The fixture ZIP supplies synthetic exercise inputs. It does not supply independently verified real-world records.
