Within the EPC/Turnkey Based projects FIDIC Silver Book will be your guide.
As my last two projects were EPC based and the last one is PPP (Public-Private Partnership) Infrastructure-Highway project within a multinational joint venture private partnership side on the other hand and if you have in the same kind of project (These days most of the Gulf projects based on PPP) you will see that your project is differentiated between sides of the projects like as below.
PPP —> PVT – Authority —> PVT – EPC Contractor –> EPC Contractor – Subcontractors ( Design & Execution)
That kind of structures could be really tough as a result of different needs of the parties in the different phases of the project and for this kind of situations New FIDIC DBO (aka FIDIC Gold Book) could be your solution.
