5 - The Tendering Phase: Preparation and Submission of an Offer
The Tenderers should carefully read the ITT/RFQ package and the related documents mentioned there, in order to be able to submit a tender that will be admitted for full evaluation, with the best possible chances of success.
With regard to the preparation of the tender, some general purpose information can be found on the page: How to prepare a good proposal: overall.
During the tendering phase, Tenderers may ask the Agency to clarify specific points in the ITT/RFQ, or request an extension to the closing date. Such requests must be made in writing and exclusively to the relevant Contract Officer indicated in the ITT/RFQ cover letter. After an internal review, the Agency shall alert all Tenderers to the request for clarification and the corresponding answer, and/or communicate an extension to the closing date for the ITT/RFQ.
The system does not accept the submission of tenders after the closing date and time indicated in the cover letter of the ITT/RFQ.
Tenderers are encouraged, prior to the closing date, to upload to the esa-star system (without "Releasing" to the Agency) a preliminary version of their tender in order to familiarise themselves with the system and identify any technical problems well in advance, so that these can be resolved before the closing date and time of the ITT/RFQ.
