In identifying trends, survey responses were particularly revealing. Trends for infrastructure PPPs included:
• Increasing popularity
• Public sector clients welcoming the possibilities of PPPs
• Financing moving to center stage
Not all trends were positive, however, with respondents noting the lack of consistent enabling legislation, conflicting public sentiment regarding tolls and taxes, and a lack of understanding of PPPs by the general public. These factors are detrimental to adoption of public-private partnerships as a mainstream method of procuring infrastructure.
