Advisory for PPP Structures, Approvals & Compliance
Public–Private Partnership (PPP) projects play a central role in Thailand’s long-term development strategy. These projects enable the government to collaborate with private investors to deliver infrastructure, utilities, and public services more efficiently. While PPPs offer strong commercial opportunities, they also require strict compliance with the Public–Private Partnership Act and its subordinate regulations.
BASE Law Firm assists clients in navigating these regulatory demands, structuring PPP engagements, and managing the approval process with clarity and efficiency.
PPP arrangements involve cooperation between a state agency and a private entity to finance, construct, manage, or deliver public-service assets. These undertakings are governed primarily by the Public–Private Partnership Act B.E. 2562 (2019), which sets out procedures, required studies, and necessary approvals before any project is launched.
A PPP project typically includes:
Foreign investors may participate, provided they follow Thai investment, land-use, and sector-specific laws.
Under the Act, the following types of undertakings generally require PPP review and approval:
Any project falling within these categories must comply with mandatory feasibility studies, financial assessments, and state-agency submissions
PPP projects must undergo a structured evaluation and approval framework before implementation. The process typically includes:
Government agencies must assess whether the project qualifies as a PPP and whether it aligns with national and sector development plans.
A detailed study is required, covering legal, financial, economic, social, and environmental aspects. This assessment is crucial to determining whether a PPP structure is appropriate.
The responsible agency must submit the feasibility study to the PPP Committee for review. Approval is mandatory before further steps can be taken.
Projects with significant budgetary impact or national importance may require approval from the Council of Ministers.
Following approval, the procuring agency must follow transparent, competitive selection procedures, ensuring fairness and compliance with procurement regulations.
Once a private partner is selected, the contract must reflect obligations, risk allocation, performance indicators, payment mechanisms, and enforcement rights.
The supervising agency must track compliance throughout the project lifecycle, including construction milestones, service levels, operational benchmarks, and financial reporting.
Thailand recognizes several PPP models, including but not limited to:
The choice of model depends on the project’s infrastructure requirements, risk profile, financing structure, and long-term operational objectives.
