See II.2.4).

The market will be split into 1 firm and 3 conditional tranches:

- firm tranche: preliminary draft,

- conditional phase 1: final project,

- conditional phase 2: "contract award" project,

- conditional phase 3: execution project.

The objective is for the adjudicator to be given the opportunity not to award conditional installments in case of non-compliance with his expectations.

The conclusion of the contract is for the entire contract, but only for the firm tranche. The execution of each conditional phase is subject to a decision by the contracting authority, which is brought to the attention of the successful tenderer.

The adjudicator therefore reserves the right not to order the conditional installments and the purchaser can not claim any compensation for this fact.

The tenderer offers and agrees for the firm tranche and the conditional tranches, so he is committed to the entire market.
