Building Confirmation and Inspection Service

The owners that are about to start construction are obliged to acquire a certificate confirming that their architectural plans conform to the Building Standard Law and related regulations before construction begins. The owner is also obliged to acquire a certificate confirming that, after completion of the construction work, the building was subject to a final inspection before it was put into use and that it conforms to the relevant laws. We issue Confirmation Certificates and Inspection Certificates as a Designated Confirmation and Inspection Body.
