# Hot beverage vending machines at AdDP and SIMDOURO facilities

The canonical acinGov snapshot identifies an open public tender by Águas do Douro e Paiva, S.A. for supplying hot beverages through automatic vending or dispensing machines at the AdDP and SIMDOURO premises. It says the exact publication date, deadline, CPV, value and award criterion are in a public procedure ZIP. The exact procedure-number search returned HTTP 403, so those details and any original notice body could not be retrieved. The notice gives no deadline in the available snapshot; value, classifications and award criteria are also unverified. No procurement files were accessed.
