Fast track procedure for adjusting the price

As we get closer to the bid submission deadline, it may prove to be more and more difficult to accommodate the normal tender file generation process even if technically speaking it can be done only within minutes.


This could indeed lead to block the whole price integration process. For this reason, a fast track procedure has been defined that allows the upper tier to make global changes to the prices of the sub-contractor's tender file. This procedure must however be used with parsimony since it leaves traces of unsettled negotiations.
