As the design and construction risk was fully stepped down from the PPP contract to the construction contractor under the construction contract, claims for cost overruns and time delays were submitted in the first instance by the construction contractor to the Project Company. The Project Company would review and assess the validity of each claim made by the construction contractor and submit a corresponding claim to the Procuring Authority for its review and approval. No specific challenges have been identified by the stakeholders interviewed in relation to change management.
