1. Official sources come before secondary summaries
For Ukrainian regulatory or legal statements, the preferred sources are official public records: legislation, Cabinet of Ministers decisions, the Unified State Electronic System in the Construction Sector, ministries and other competent public authorities.
For procurement evidence, ShelterMetric uses the public procedure, plan, contract and supporting documents where available. A secondary article may help identify a development, but it should not replace the primary source when the primary source is available.
2. Ukrainian regulatory categories remain the reference point
English terms such as “radiation shelter”, “dual-purpose structure” or “primary mobile shelter” are communication aids. Where a legal or technical distinction matters, the Ukrainian regulatory category and source document remain authoritative.
The commercial word “bunker” is not treated as a regulatory status by itself.
3. A planning tool is not an engineering conclusion
ShelterMetric calculators structure early project thinking: capacity, area, budget, logistics, funding, schedule, maintenance and procurement scope. They do not certify compliance, structural performance, protective properties, legal eligibility or the suitability of a specific site.
Project-specific conclusions may require design documentation, surveys, engineering calculations, expert review and the involvement of qualified specialists.
4. Unknown values stay unknown
We avoid pre-filling project fields with sample capacity, area, price or other values that could later be mistaken for real project data. If the user has not supplied a value and no verified source establishes it, the value remains unknown.
This principle is especially important when data moves between connected tools through the shared Project Passport.
5. No hidden market price, reserve or currency assumptions
- ShelterMetric does not insert an automatic “market price” for a shelter project.
- Budget-reserve tools start without a universal contingency percentage; the user defines the scenario.
- Logistics tools do not assume return mileage unless the user chooses it.
- UAH, USD and EUR inputs are not silently converted between currencies.
- Maintenance and lifecycle-cost tools use user-entered project assumptions rather than invented tariffs.
6. Base budget is kept separate from risk and lifecycle scenarios
The Project Passport budget field is intended for the project’s base budget. A reserve scenario, logistics scenario, supplier comparison, annual maintenance budget or total cost of ownership should not silently overwrite that base figure.
Where connected tools save those scenarios to the Project Passport, they are stored as notes or project context so the distinction remains visible.
7. Public procurement figures are labelled by what they actually represent
An expected procurement value is not automatically a final implementation price. A winner’s offer, contract value and actual payments are separate indicators. ShelterMetric keeps these distinctions visible when the source data allows it.
Supply of a prefabricated or mobile shelter is not compared directly with capital construction, reconstruction, repair or standalone engineering works as if they were the same commercial product.
8. Repeated and cancelled tenders are not counted as separate completed projects
Cancelled procedures remain part of the public history, but they are not presented as confirmed implementation prices. Where the same object is retendered, ShelterMetric can preserve each procurement ID while grouping related records into one unique project for project-count analytics.
Grouping is based on project evidence such as the object, address, buyer, scope and supporting documentation; it is not based only on similar titles.
9. Funding tools do not guess eligibility or co-financing rules
A funding programme does not automatically make a project eligible. Programme requirements, priorities, budget periods and co-financing rules must be checked against the current official conditions of the relevant mechanism.
The co-financing calculator therefore models only the amounts entered by the user and does not invent a mandatory percentage. Unconfirmed funding is not treated as secured funding.
10. Date and source status matter
Fast-changing regulatory, funding and procurement topics are checked against current source material before new claims are added. Historical examples keep their original dates and are presented as historical evidence rather than silently converted into current rules or current market prices.
