KfW’s Environmental and Social Experts (formerly KCUS and regional E&S experts) provides services in the field of environmental and social sustainability for KfW Development Bank, KfW IPEX-Bank and other business units of KfW. The objective of this tender is to establish a framework agreement with three environmental and social consultancy firms (Consultants) to provide expert services required by the E&S Experts as the case may be. The Consultants will perform the tendered services on the basis of single assignments. E&S will either allocate them on the basis of a cascade-system if the services to be executed are standard tasks or by awarding them on grounds of a mini-competition between the three Consultants if the services to be performed are non-standard tasks. Both procedures are described in detail in the Framework Agreement. KfW has planned that the required max. number of person-days required during the entire term of the framework agreement is estimated to amount to 1710.
