In this regard it appears from preparatory legislative works that the rationale behind a gradual opening of the market was to ensure that the Public Road Administration could continue to adequately control and ensure that road standards and safety would be kept at a satisfactory level [101].The Norwegian authorities have further explained that this is also the motivation behind tendering out the most risky and demanding contracts at the end of the process while the simplest and smallest were tendered out first [102]. By leaving the most challenging contracts to the end, the Public Road Administration would already have obtained a fair amount of experience from having supervised and monitored several service providers after the first tender rounds.
A este respecto, de los trabajos legislativos preparatorios se deduce que las razones para una apertura gradual del mercado eran asegurarse de que la Administración de Carreteras pudiera continuar controlando y asegurando adecuadamente la observancia del estado de las carreteras y de la seguridad vial [101].Además, las autoridades noruegas añadieron que esta es también la razón de licitar contratos más arriesgados y difíciles al final del proceso, mientras los más simples y pequeños lo fueron al principio [102].
