Business Entity Certificate for Engineering & Design • 30 Sub-classification & KBLI Codes
The Sertifikat Badan Usaha (SBU) Konsultan Konstruksi is the mandatory operational credential required for engineering consulting, architectural planning, project supervision (MK), and technical testing firms in Indonesia. Issued through accredited LSBU certification bodies and officially recorded on LPJK and OSS-RBA under Government Regulation PP No. 5/2021.
Every consultant SBU sub-classification requires verified matching KBLI codes (primarily 71101, 71109, 74191, and 71209). Below is the complete catalog of all 30 official sub-classifications across Architectural (AR), Engineering (RK), Integrated Engineering (RT), Spatial Planning (AL), Scientific & Technical Consulting (IT), and Technical Testing (AT).
Minimum financial net worth, project limits, and certified expert personnel (SKK) per firm scale:
| Scale (Kualifikasi) | Min. Financial Equity | Max. Consulting Value | PJT (Technical Lead) | PJSK (Sub-field Lead) |
|---|---|---|---|---|
| Small (Kecil) | IDR 100,000,000 | Up to IDR 1 Billion | SKK Level 7 (Ahli Muda) | SKK Level 6 |
| Medium (Menengah) | IDR 500,000,000 | Up to IDR 2.5 Billion | SKK Level 8 (Ahli Madya) | SKK Level 7 |
| Large (Besar / BUMN) | IDR 2,000,000,000 | Unlimited (> IDR 2.5 Billion) | SKK Level 9 (Ahli Utama) | SKK Level 8 |
