2. Outcomes of BRI R&D Project

20

Outcomes of BRI Research Project

• The 1st achievement of BIM building certification• Building certification by accepting BIM model file has kicked off!

• “Jyutaku seino hyouka center,” the designated confirmation and

inspection body executed building certification by accepting BIM

model as the 1st achievement in Japan.

• bSJapan Regulatory WG• Regulatory WG under the Architectural & Cross Domain Group is

settled by buildingSMART Japan.

21

The 1st achievement of BIM building certification

FREEDOM ARCHITECTS DESIGNApplicant:

Confirmation body:

BIM software/solution bender:

Freedom Architects design, the applicant and Jyutaku seino hyouka center, the

designated confirmation and inspection body developed a “Revit based” BIM

building certification solution in collaboration with Otsuka Corp. and Autodesk.

In Aug. 2016, 2 building certification was issued using by this solution, These 4

companies jointly issued a press release announcing the outline at Sep. 1st, and

Freedom Architects design made the speech at Autodesk University Japan 2016

about the detail at Set. 6th.

bSJapan Regulatory WG

• bSJ Reg. WG has three missions as follows;

• Inspection of MVD certification for BCC IFC inspection

• Study on BIM use technology in a Building confirmation and

inspection in practical affair

• Corresponding to bSI RR’s projects in bSJ

• Convener and Participants• Convener:

Masaki MUTO / Building Research Institute

• Constitution of participants:

confirmation body, architectural design office, general contractor,

home builder, software solution vendor and interested individuals

Representation of procedure and information delivery

to develop common understanding

Classification of information delivery could be classified from the kind

of information format as legal requirement and its treatment during

the procedure of BCC.

Proposal for the questionnaire for international

comparison of information deliveryThe questionnaire is to clear the facts about;

• Which approval is needed in each country?

• After which design process is it applied for the approval?

• What documents or drawings are needed legally on paper based,

paperless and BIM based submission?

• What expressive elements are specified for each document or

drawing?

• Which building code does each expressive element correspond

to?

• What type is the criterion for adaptation of building code?

(e.g. existence, text, numbers, numerical value or

spatial/geometrical relation of targets, or results of calculation,

simulation or analysis)
