The Procuring Authority needs to understand and prepare its team for the volume of data and documentation that it will be required to review and sign off during the transition from financial close to construction. It is common for the Procuring Authority to require oversight of detailed design and the quality of materials, and therefore it needs the team and processes in place to support this oversight and to ensure that it can respond within the timelines set in the PPP contract. PPP projects can involve greater discretion for the Project Company to design the project than what would typically be seen in a traditional design and construct contract. This will mean that the design sign-off procedures will be more complex than what they would be if the Procuring Authority had contracted directly with the construction contractor. This additional complexity should be taken into account to ensure that the Procuring Authority complies with its approval obligations in the time required in the PPP contract.
