19.5 Any attempt by tenderers to influence the evaluation committee in the process of  examination, clarification, evaluation and comparison of tenders, to obtain information on  how the procedure is progressing or to influence the contracting authority in its decision  concerning the award of the contract will result in the immediate rejection of their tenders.  19.6 All tenders received after the deadline for submission specified in the contract notice or these  instructions will be kept by the contracting authority. The associated guarantees will be  returned to the tenderers. No liability can be accepted for late delivery of tenders. Late  tenders will be rejected and will not be evaluated.  20.1 Examination of the administrative conformity of tenders  20.2 Technical evaluation  20.3 In the interests of transparency and equal treatment and to facilitate the examination and  evaluation of tenders, the evaluation committee may ask each tenderer individually for  clarification of its tender including breakdowns of prices, within a reasonable time limit to be  fixed by the evaluation committee. The request for clarification and the response must be in  writing, but no change in the price or substance of the tender may be sought, offered or  permitted except as required to confirm the correction of arithmetical errors discovered  during the evaluation of tenders pursuant to Article 20.4. Any such request for clarification  must not distort competition. Decisions to the effect that a tender is not technically compliant  must be duly justified in the evaluation minutes.  20.4 Financial evaluation  a) Tenders found to be technically compliant will be checked for any arithmetical errors in  computation and summation. Errors will be corrected by the evaluation committee as  follows:  -  where there is a discrepancy between amounts in figures and in words, the amount  in words will be the amount taken into account;  August 2020 c4b_itt_en.doc  Page 12 of 17  After analysing the tenders deemed to comply in administrative terms, the evaluation  committee will rule on the technical admissibility of each tender, classifying it as technically  compliant or non-compliant.  The minimum qualifications required (see selection criteria in the additional information  about the contract notice are to be evaluated at the start of this stage.  Where contracts include after-sales service and/or training, the technical quality of such  services will also be evaluated by using yes/no criteria as specified in the tender dossier.  If a tender does not comply with the tender dossier, it will be rejected immediately and may  not subsequently be made to comply by correcting it or withdrawing the departure or  restriction.  Substantial departures or restrictions are those which affect the scope, quality or execution of  the contract, differ widely from the terms of the tender dossier, limit the rights of the  contracting authority or the tenderer’s obligations under the contract or distort competition  for tenderers whose tenders do comply. Decisions to the effect that a tender is not  administratively compliant must be duly justified in the evaluation minutes.  The aim at this stage is to check that tenders comply with the essential requirements of the  tender dossier. A tender is deemed to comply if it satisfies all the conditions, procedures and  specifications in the tender dossier without substantially departing from or attaching  restrictions to them.  20.
