Questions
What is a contrato menor in Spain?
A minor contract: under €40,000 for works or €15,000 for supplies and services, excluding VAT. The buyer can award it directly to any capable company, for up to one year with no extension; minor contracts are published quarterly after the event.
What are the pliegos?
The tender documents: the pliego de cláusulas administrativas particulares (PCAP) sets the legal and administrative conditions, award criteria and documents required; the pliego de prescripciones técnicas (PPT) sets the technical specifications.
What is a baja temeraria?
The informal term for an abnormally low bid (oferta anormalmente baja). The tender documents set the parameters; a bidder flagged as abnormally low must justify its price, and its bid can be rejected if the justification fails.
