OIMAP buys goods and services for its operations: IT, printing, translation, event hosting, consulting services. Above a threshold of €40,000 (indicative), a purchase is subject to competitive tendering.

Notices are published online and accessible to all companies, whatever their country. This page complements the public documents and the oversight exercised by the audit.

The principles

The Organization's purchases rest on four principles: equal treatment of candidates, transparency of the procedure, sound use of public funds and prevention of conflicts of interest. No candidate receives information that is not communicated to all.

The Administration and Finance Directorate conducts the procedures. An evaluation committee separate from the requesting department examines the bids, to prevent the same staff member from both specifying and awarding.

Procedure thresholds

Below €10,000 (indicative), the purchase is made by direct agreement, with written justification. Between €10,000 and €40,000, at least three quotes are requested. Above €40,000, a call for tenders is published, with specifications and weighted criteria.

Urgent purchases, linked for example to a heritage protection operation, may follow an accelerated procedure. They are then reported in the annual audit report.

Submitting a bid

The procurement notice states the subject, the duration, the documents to be provided and the deadline. Candidates submit their questions in writing; the answers are communicated to all. The bid includes a presentation of the company, its references and its price.

Companies must certify that they are up to date with their tax and social obligations and that they are not in a situation of conflict of interest with staff of the Organization.

Award and monitoring

The award criteria combine price, technical quality, delivery times and, for some contracts, the ability to work in the three official languages. The result is notified to all candidates with the reasons for the choice.

Contract monitoring is entrusted to the requesting department and to the Administration and Finance Directorate. Amendments are limited and justified, and payments are made after verification that the service has been delivered.
