2- at least three (3) staff currently work for the tenderer in fields related to the lot(s)  tendered.  3) Technical capacity  (based on items 5 and 6 of the tender form for supply contracts). The  reference period which will be taken into account will be the last three years from  submission deadline.  1- the tenderer has provided supplies under at least two (2) contracts with a budget of  at least 50% of the amount offered for the tendered lot, in the field relevant for the  tendered lot, which were implemented at any moment during the reference period:  last three years.  Criteria for legal and natural persons: This means that the contract the tenderer refers to could have been started or  completed at any time during the indicated period but it does not necessarily have  to be started and completed during that period, nor implemented during the entire  period. Tenderers are allowed to refer either to projects completed within the  reference period (although started earlier) or to projects not yet completed. In the  first case the project will be considered in its whole if proper evidence of  performance is provided (statement or certificate from the entity which awarded  the contract, final acceptance). In case of projects still on-going only the portion  satisfactorily  completed  during  the  reference  period  will  be  taken  into  consideration. This portion will have to be supported by documentary evidence  (similarly to projects completed) also detailing its value. If a candidate has  implemented the project in a consortium, the percentage that the candidate has  successfully completed must be clear from the documentary evidence, together  with a description of the nature of the services provided if the selection criteria  relating to the pertinence of the experience have been used.  The relevant fields of expertise for this purpose are as follows:  Lot 1: I nland surface and groundwater monitoring  Lot 2 and 3: Groundwater monitoring  Lot 4: IT Equipment  Lot 5 and 6: I nland and marine water monitoring  Lot 7, 8, 9, 10, 11, 12, 13, 14 and 15: Marine Water Monitoring  Previous experience which caused breach of contract and termination by a contracting  authority shall not be used as reference. An economic operator may, where appropriate and for a particular contract, rely on the  capacities of other entities, regardless of the legal nature of the links which it has with them.  If the economic operator relies on other entities it must in that case prove to the contracting  authority that it will have at its disposal the resources necessary for performance of the  contract by producing a commitment by those entities to place those resources at its disposal.  Such entities, for instance the parent company of the economic operator, must respect the  same rules of eligibility and notably that of nationality as the economic operator relying on  them and must comply with the selection criteria for which the economic operator relies on  them. Furthermore, the data for this third entity for the relevant selection criterion should be  included in a separate document. Proof of the capacity will also have to be provided when  requested by the contracting authority.  With regard to technical and professional criteria, an economic operator may only rely on the  Capacity-providing entities  Page 4 of 6  August 2020  a5f_additional_information_contract_notice_en 1
