Building Approval (PBG) is the legal basis before a building is planned, built, or used. For project owners, PBG is not only an administrative requirement, but a way to verify that the technical plan follows zoning, building function, and safety standards.

Why Should PBG Be Prepared Early?
PBG often takes longer when technical documents are only organized after the design is nearly complete. A better approach is to consider regulatory requirements from the concept stage, so architecture, structure, and MEP planning move in the same direction.
The earlier regulatory requirements enter the design process, the lower the risk of major revisions during submission.
Commonly Required Documents
- Owner data and land legality information.
- Architecture, structure, and utility drawings.
- Technical calculations based on building function and classification.
- Supporting documents required by the local authority.
Recommended Workflow
- Validate building function and zoning requirements.
- Review early design against technical requirements.
- Prepare drawings and calculation documents.
- Submit, coordinate, and revise documents when required.
With structured technical assistance, project owners can understand document status, revision risks, and next-step estimates more clearly.
