Confirmation and inspection procedures are required before and during the erection of a building, respectively. BCJ has rationalized this process and reduced the lead time by integrating these confirmation and inspection procedures with the performance evaluation and the approval processes under the Building Standards Act. BCJ has also been entrusted by Japan Housing Finance Agency to conduct assessments and inspections.
In addition, BCJ performs housing performance evaluations under the Housing Quality Assurance Act. (Started in autumn 2000)

As a designated body under the Building Standards Act, BCJ performs structural calculation conformity reviews for buildings of a certain size or larger, etc. at the request of building officials or designated confirmation and inspection bodies. All of the reviewers have highly specialized knowledge and skills. (Started in June 2007)
