EUOSHA/2021/OP/F/SE/0142  level).  Other members of the team:  • qualified expert (senior profile), having received a high- level training in his or her profession, recruited for his or  her capacity for thought and creativity in his or her work;  • the expert must have at least five years’ professional  experience, in which at least 2 must be connected with the  professional sector concerned and the type of tasks to be  performed.  • a very good knowledge of written and spoken English (C1  level).  The  other members  of the team (junior profile) must have at  least 2 years of experience in carrying out the tasks referred to  in section 2.3 .  Basis for assessment  This criterion applies to the tenderer as a whole, i.e. the  combined capacities of all  involved entities .  Evidence  The following evidence must be provided to fulfil the above  criteria:  • the educational and professional qualifications of the  persons who will provide the service for this tender  (anonymised CVs), including the management staff; each  CV provided must indicate the intended function in the  delivery of the service.    If the contractor proposes changes in the core team during the life of the framework contract,  prior consent should be formally requested to EU-OSHA. The new member(s) of the team  should never have — at the time of joining EU-OSHA assignment — fewer years of experience  of the services required in this lot than the equivalent profile(s) defined in the tender (see table  below). The contractor will be entirely responsible for the necessary handover and know-how  transfer to, and induction of, the new member(s) as regards EU-OSHA’s projects and activities;  in no way should EU-OSHA and the quality of the services contracted be negatively impacted  by the change(s).  The tenderer is expected to assign the sufficient number of staff members and a balanced  proportion of senior and junior profiles to undertake all requested activities/services to the  highest quality standards and within the established deadlines.
