Calculation

Intratec's indexes and cost estimates are derived from underlying raw data using transparent, reproducible models.

Cost Indexes

Plant construction and labor cost indexes are calculated as weighted composites of component costs. Weights reflect the typical cost structure of industrial facilities in each economy.

Normalization

All monetary values are expressed in USD. Local currency values are converted using period-average exchange rates published by the IMF.

Historical Revisions

When source agencies revise historical data, Intratec propagates those revisions forward through the model. Revision notes are published alongside each affected dataset release.
