K&M was engaged by the Government of Thailand to prepare a manual for conducting project appraisals and market sounding of infrastructure projects with private sector participation. The manual describes key principles and techniques for project appraisal, summarizes relevant international best practices, and provides examples and short case studies to illustrate key concepts of Public-Private Partnerships (PPP). The manual is designed as a guide to PPP procurement practices for Government staff, and it covers a full range of PPP concepts, including project structuring, risk allocation, Value for Money (VfM) analysis, financial viability analysis, and the identification and valuation of fiscal commitments.
