The PPP project must be clearly specified, including the allocation of risk and a clear statement of the service output requirements. The long-term nature of PPP contracts requires greater consideration and specification of contingencies in advance. Transaction advisors and other consultants would need to be appointed to assist the public entity to handle the challenges involved in project structuring and procurement process. On the other hand, the public entity finds it less complex to carry out conventional procurement because it is accustomed to this arrangement where a well-established procedure has been in place for a long time.
