EUOSHA/2021/OP/F/SE/0142  • Expert conferences/seminars : every year, EU-OSHA organises one onsite full-day seminar  in Bilbao for around 120 participants, with two-way interpretation in five EU languages. In  addition, four to six online seminars or conferences for up to 200 participants, without  interpretation, are organised and held in Bilbao or Brussels every year. • Expert workshops : every year, EU-OSHA organises around two to three full-day expert  workshops for up to 20 participants in Bilbao and another two to three workshops in Brussels  or other EU locations. • Exhibition stands : EU-OSHA regularly participates as an exhibitor at congresses or fairs. In  the next 4 years (2022-2025), up to four of these events will take place in Bilbao, five within the  EU and two outside the EU. • Additional events : the contractor may be asked to deliver other ‘events’ in addition to those  mentioned above. Internal events, such as one staff event per year for up to 65 participants in  Bilbao or another location, and other team-building events are expected. These events include,  but are not limited to, two coaching/training events for up to 20 participants per year taking  place in Bilbao, cultural visits including lunches and transport, arranging catering services for  up to 65 participants for other events held in EU-OSHA premises (three times per year).  Depending on the complexity of the event, EU-OSHA shall strive to send the contractor a request for  services up to 45 calendar days prior to the event. For smaller meetings, notice of up to 21 calendar  days prior to the event should be considered sufficient. EU-OSHA will provide the contractor with the names of the key people and institutions to be invited to  and represented at the event, along with the draft programme for the event. Alternatively, EU-OSHA  could request the contractor to prepare a concept for the event, including a draft programme and  general set-up, and to propose other relevant participants to invite.  As described in the corresponding request for services, the contractor shall carry out all or only some  of the creative, advisory, logistical and technical activities related to the organisation and smooth  implementation of these events.  If required by the relevant legislation, the contractor must take out an insurance policy against risks  and damage or loss relating to the implementation of the framework contract. It must also take out  supplementary insurance as reasonably required by the standard policy of the industry. In addition, it  is the contractor’s responsibility to ensure that any economic operator involved at its request in an  event’s organisation is appropriately covered by civil responsibility insurance and any other  insurance required by EU, national and/or local regulations. Upon request, the contractor must  provide evidence of insurance coverage to EU-OSHA. The contractor is also responsible for ensuring compliance with safety and security rules at all times  and that all equipment needed for the event is appropriately covered against any risk of damage, loss  or theft (headsets, IT equipment, etc.).  At the request of EU-OSHA, depending on the type of event, the contractor shall be required to  undertake one or more of tasks outlined in  sections 2.3.1  to  2.3.14 . The tasks may include, but are  24
