Guidance Note: The Participants' commitment to acting in good faith is the overriding commitment made by the Participants to each other when entering into the alliance contract. In a general sense, acting in good faith encompasses the Participants acting fairly, reasonably and with integrity, and openly and honestly with each other in everything they do under the alliance contract and doing all things necessary to give effect to the intent of the alliance contract. In respect of fairness and reasonableness, the Participants must make best-for-project (rather than best-for-self) decisions with the aim of producing outcomes where all Participants will win equally or lose equally, based on the objectives of the Project (e.g. the materials required for the Works must be purchased on a cost and quality basis only).

In respect of openness and honesty, the Participants must have a 'communication culture' and be transparent in all of their dealings with each other in respect of the Project, share all information and not hold back ideas (e.g. during the development of the TOC, if a Participant has a idea regarding innovation or cost reduction, this should be communicated to the other Participants prior to the TOC being settled, not later).

Finally, each of the Participants must formally commit to the spirit and intent of the alliance contract, do all things to deliver the Project and achieve its objectives and not use the words of the alliance contract to attempt to absolve itself of responsibility and in a manner which is best-for-self.

The Non-Owner Participants' commitment to acting in good faith is also demonstrated by ensuring that their nominated Non-Owner Participant team members are made available to the project, for the duration of the project, as per their bid offer.
