3. Future plans
In 2011, a standards revision system was operated
centered on responses to earthquake disaster damage,but in the future, the revision of technical standards
will also be studied in response to the progress ofsurvey research.
In February 2012, the National Institute for Landand Infrastructure Management conducted large-scale
fire tests in a wooden three-story school building, andin the future it will establish a committee concerning
fire prevention and evacuation in order to study therevision of technical standards related to fire
prevention based on the tests.

窓口 コ(ンタクトポイント )2. Building Structure Standards Committee
To achieve the above goals, the Building StructureStandards Committee (Chairman: Professor Kubo
Tetsuo, University of Tokyo) was established at theNILIM as an organization to reflect the view ofoutside experts in technical standards proposals
prepared by the Building Department.
Since the Great East Japan Earthquake of March 11,
the building structure field has had to respond quickly
to its damage, so this committee was established onApril 12, and carried out field surveys of the disasterregion on April 21 and 22. Based on this, thecommittee met for the first time on June 8 to confirm
the early reports on surveys of the damage and discuss
immediate challenges. It met for the second time inAugust, when it energetically carried out a study, thenat its third meeting in October, it presented andapproved the proposal, Provisional Guideline toStructural Conditions Essential for Tsunami

Evacuation Buildings Etc. in Response to the Great
East Japan Earthquake. Later a notification (KokujushiNo. 2570 of November 17, 2011) was issued by theHousing Bureau, and its contents were reflected intechnical standards under the Tsunami DisasterProtection Region Establishment Law.
The committee found extensive damage such as
fallen ceilings in large spaces, so it is studying related
technical standards.

1. Background
The Building Standard Law stipulates minimum
standards to ensure the safety of buildings andprescribes many technical standards concerning allbuilding construction related fields such as structures
or fire protection. And in addition to the BuildingStandard Law, there are other laws such as theTsunami Disaster Protection Region Establishment
Law enacted last year which also stipulate building
construction related technical standards.
These building construction related technicalstandards must be revised as necessary according toprogress in survey research and technology
development and to disasters trends. BuildingStandard Provision Promotion Projects have been
conducted as projects subsidized by the Ministry ofLand, Infrastructure, Transport and Tourism as a way
to promote related survey research, and as a system tocarry out standardization based on its achievements,
the National Institute for Land and InfrastructureManagement (below, “NILIM”) has operated a system
including outside experts since 2011.
