Core standards
- Defined scope: pages explain project-cost methods rather than pretending to provide universal prices.
- Traceable reasoning: formulas, assumptions and boundaries are shown where practical.
- Source quality: priority is given to official public guidance and primary sources.
- Separation of fact and example: sample numbers are labelled as examples.
- Uncertainty: estimates are not presented as guarantees.
- Conflicts: advertising does not determine conclusions or page topics.
- Corrections: material factual errors are reviewed and corrected.
Use of automated tools
Software and automated assistance may support drafting, consistency checking, link checking and calculations. Final published pages are reviewed for coherence, limitations, duplication and suitability for this site.
Updates
Evergreen concepts are reviewed periodically. External links and policy pages may be updated when source requirements change. A page may remain useful even when its review date is older, but readers should verify time-sensitive rates, laws, standards and organization-specific procedures.
Advertising boundary
Advertisements may appear automatically through third-party systems. An advertisement is not an endorsement, and advertisers do not review or approve the editorial content.
