Any material changes to the PPP contract have to abide by applicable procurement regulations. However, for smaller changes, the parties have found a way to smooth the process. It starts by one party submitting an informal notice of change, which explains the nature of the change and the reasons behind it. Keeping in mind that the change should be within regulations and the remits of the PPP contract, the informal notice is issued one month before the formal notice is issued. This is done to give each party the opportunity to review the notice, suggest amendments, and adapt to its implementation before it is formalised.
