4 Stages of Dam Construction Permitting in Indonesia (PUPR Reg. 27/2015)

Dam construction in Indonesia involves high-hazard infrastructure regulated strictly by the Ministry of PUPR under Ministerial Regulation No. 27/PRT/M/2015.

4 Stages of Dam Permitting in Indonesia

Dam construction licenses are granted in four distinct phases approved by the Minister of PUPR based on Dam Safety Commission (KKB) evaluations:

1. Dam Design Safety Certification

Before construction begins, the engineering design must undergo evaluation by the Dam Safety Commission. Requirements include:

• Dam Break Analysis & Inundation Mapping
• Seismic Hazard & Geotechnical Foundation Studies
• Physical Hydraulic Model Testing for Spillways

2. Construction Execution Authorization

Following design certification, proponents apply for a Construction Permit supported by Quality Management Plans, Cofferdam DED, and Dam Safety Plans.

3. Initial Reservoir Impounding Permit

Prior to filling the reservoir, KKB experts perform field inspections of piezometer instrumentation, seepage behavior, and Emergency Action Plans (EAP).

4. Long-Term Dam Operation Permit

Granted after successful initial impounding evaluation and confirmed structural stability.
