ECHA/2020/666  Annex 1 to Tender Specifications  Technical Specifications Restricted  62 (77) handover, ECHA is entitled to receive 10 to 20 person-days of work at no charge.  Such replacement will bear no additional cost to the Agency. The agreement will  be formalised by exchange of e-mails or another means of electronic exchange.  In any case, the contractor shall propose one or more suitable candidates at equivalent  qualifications and experience as the replaced resource. If the contractor cannot propose  suitable replacement in a timeframe that does not have a negative impact on the  performance of the specific contract, ECHA may seek compensation, exercise contractual  remedies, as provided for in the FWC666.  ECHA will request that resources be categorised into core and extended team members.  The contractor shall then provide such lists in their offer. ECHA reserves the right to  review, approve and/or reject the proposal for resources allocated in the core team. The core team shall typically comprise contractor ’s staff who have acquired specific  knowledge of ECHA IT projects and/or IT services.  All contractor’s sta ff categorised as core  team members will be considered as pool of core team members at FWC666 level for any  subsequent assignment. In this sense, ECHA expects deployment of core team members  in relation to the expert knowledge for the related assignment. In addition, the contractor  shall ensure the availability of a specific core team member when directly identified and  requested by ECHA for a specific assignment.  ECHA can ask for additional proof of competence in the form of diplomas, certificates and  references of studies, training, technical competence and work experience alleged in the  CV of candidates proposed for a specific contract. ECHA may take into account only the studies, training, technical competence and work  experience, for which sufficient evidence is actually provided.  The contractor shall submit CVs only in Europass format. The CV must clearly demonstrate  that the candidate fulfils the profile requirements of the FWC666, including where relevant  the years of experience with specific technologies and/or methods. The contractor shall  ensure that all information indicated in the CV is up-to-date, known to and validated by  the candidate.  Unless otherwise agreed with ECHA, the contractor shall ensure the retention of staff  categorised as core team members. For any replacement of core staff, ECHA shall be  notified in due time and with sufficient notice to ensure that adequate knowledge ramp- up arrangements can be put in place (at no extra costs for ECHA), including adequate  handover activities from the staff being replaced in order to minimise the disruption to  service delivery and in general to ensure that adequate level of expertise and knowledge  is maintained for the execution of the services. In this respect, ECHA reserves the right to  reject a replacement and request a new replacement (the Contractor being informed on  the reason for the rejection). A notice period of at least 15 working days shall be observed for any replacement of core  team members. P.O.
