Technical specifications

It is the responsibility of the contracting authority for the bus acquisition project to draft the technical specifications in accordance with the needs it will have identified (state of the fleet and the network, agglomeration and mobility development prospects, configuration and state of the roads, strategies of the public authorities with regard to the improvement of urban mobility and the modernisation of the transport offer, climatic context, etc.). Beforehand, it will also have taken note of the bus manufacturers’ offer, for an initial assessment of the vehicles whose structural and technical characteristics could fulfil its needs (the price level will also form part of this initial assessment).

The technical specifications will form the basis of the invitation to tender and the contractual commitment of the selected manufacturer.
