How this track was built
This track was generated from DE_BERLIN by
0_Workflow and Pipelines CWICR/python/11-country-track-builder/add_country_track.py.
- Norms (labour hours, machine hours, resource quantities) are identical to the source track — Resource-Based Costing methodology treats norms as country-agnostic physical first principles.
- Prices are derived via the cascade
type_factors → location_factor → optional national overrides. Type factors come from OECD wage indexes (labour), construction PPP (material), and ECB FX (equipment). FX snapshot date is recorded in the per-resource columns. - Language columns are translated where target language differs from source. Existing tracks are used as parallel-text seeds.
