The three official layers
- BASE.gov.pt — central record of procedures and executed contracts under the Código dos Contratos Públicos.
- Diário da República — official gazette announcements, including certain works and concession procedures.
- TED — mandatory for procedures above the EU thresholds.
The layer people miss
Direct awards and simplified procedures are recorded on BASE but are easy to overlook, and for many small suppliers they are the realistic entry point. Reading the award history of a nearby authority tells you what it buys, from whom, and at what price — which is a better prospecting tool than any open notice list.
