04 / FAQ

Frequently asked questions

Common questions on structural engineering, ground conditions, and PBG/SLF permit approvals in Bali.

Why do I need a licensed structural engineer for building in Bali?

Bali is located in an active seismic zone with diverse soil conditions, from coastal sands and soft rice-field clays in Canggu to hard limestone cliffs in Uluwatu. A certified LPJK structural engineer ensures that columns, beams, and foundations are engineered to withstand earthquake loads while avoiding expensive over-design. Official structural calculations are also legally mandatory for PBG permit approval.

What is the difference between PBG and SLF in Bali?

Persetujuan Bangunan Gedung (PBG) is the official building permit required before construction begins (replacing the old IMB). Sertifikat Laik Fungsi (SLF) is the certificate confirming the building is safe and ready for occupancy, required after completion or for existing operational buildings. We prepare the complete engineering calculations and technical inspection reports required for both.

How do you design for Bali's cliffside slopes and challenging terrain?

We review site soil test data (SPT borehole and sondir) to understand bearing layers and slip planes. Using ETABS 3D modeling, we design integrated tiered foundations, bored piles, and reinforced concrete retaining walls that anchor safely into competent ground while preserving the architectural design intent.

Are your calculations signed by an LPJK Level 7 certified engineer?

Yes. All engineering calculations and permit reports are authored and signed by I Gede Alam Suryawan, S.T., an LPJK Level 7 certified expert (Ahli Muda Teknik Bangunan Gedung) registered with the Indonesian Ministry of Public Works and Public Housing (PUPR).

Which areas across Bali do you serve?

We serve projects throughout Bali, frequently working in Badung (Canggu, Pererenan, Seminyak, Uluwatu), Gianyar (Ubud), Tabanan, Denpasar, and Karangasem. We coordinate seamlessly with local and international architectural teams.
