representative of such an entity, and the supporting evidence that those other entities have the  respective resources.  If the contract is awarded to a tenderer intending to rely on another entity to meet the  minimum levels of economic and financial capacity, the  Contracting authority may require  the entity to sign the contract or, alternatively, to provide a joint and several first-call financial  guarantee for the performance of the contract.  With regard to technical and professional selection criteria, a candidate may only rely on the  capacities of other entities where the latter will perform the works or services for which these  capacities are required.   Relying on the capacities of other entities is only necessary when the capacity of the  tenderer is not sufficient to fulfil the required minimum levels of capacity. Abstract  commitments that other entities will put resources at the disposal of the tenderer will be  disregarded.
