□ In a rapidly changing environment, such as that characterised by infrastructure PPPs worldwide, new practices develop quickly making existing ones obsolete. In preparing the Guide, an effort has been made to review and recommend the most up to date PPP guidelines and documentation currently available.
□ The Guide is written in English. Most of the PPP guidance currently available comes from countries such as Australia or the United Kingdom, for example - which have an extensive PPP experience - or from
□ international organisations, such as the World Bank, whose institutional mandate includes the gathering of best practice worldwide. In the case of the latter, although the language of the guidance is English, the content draws on experience from non-English speaking countries and therefore such sources are applicable to a wider audience.
□ The Guide also includes references to available PPP guidance material in non-English speaking European countries such as France, Germany, and Greece, for example. This Guide, however, only references the original language guidance source.
□ This Guide does not replace, to any extent or measure, the need for a public contracting authority to take professional advice from its legal, technical, financial, environmental and other advisers. The Guide should, however, assist users in having a more productive dialogue with their advisers.
