Summary
• To introduce electronic submission for building certificate
procedure including BIM technology are expected for
streamlining on confirmation of building technical
standards. And some countries already started electronic
submission with BIM technology now, e.g. Singapore.

• Building Research Institute executes the R&D project
which is aimed to clarify bottlenecks in conventional
building certificate procedure, subjects of introduction
electronic submission and application possibilities of BIM
on the procedure from FY2012 to FY2014. This topic
gives a progress report of our R&D.

BRI ‘s R&D Activities
The Building Research Institute (BRI) has been conducting various research and
development from the fair and neutral perspective of a public-sector research institute.
4 Targets of R&D shown by the MLIT
Realization of Sustainable Housing,
1) Buildings and Urban Communities by
Green Innovations
Realization of Secure and Safe
2) Housing, Buildings and Urban
Communities
Maintenance and Revitalization of
Existing Housing, Buildings and Urban
3)
Communities Coping with the
Declining and Aging Population
International Contributions by Building
4) and City Planning Technology and
Response to Informatization

conformity
Backgrounds 1/2
By the legal revision in 2007, a duty of preservation
of the application documents on building
confirmation for 15 years was imposed upon the
confirmation body.
Since the application is made on the basis of paper
medium, confirmation body is regarding as
problems the preservation place and its cost, or
documents lost.
Since CAD is generally used, is
submitting digitized application
documents and confirming possible?

Backgrounds 2/2
After the incident which camouflaged earthquake
resistance (called “Aneha” incident), the procedure
of the building confirmation tightened and change
of the contents in the procedure became difficult.
Therefore, the preliminary consultation before a
“formal reception” is prolonging the confirmation
period so that there may be no inconsistency in the
contents of application documents.
Is the BIM technology which can unify
building properties inapplicable?

The aim of this research
To develop the technology of the electronic
application of the building confirmation for achieving
the following aims;

(1) Digitize the document for application preserved
by the confirmation body.

(2) Improve the compatibility of the descriptive
content of documents for mitigating a labor
required for confirming work.
