Regulation to promote Seismic Retrofit ofBuildings along the Emergency
Transportation Roads in TMG

Building Planning Section
Urban Building Division
Urban Development Bureau1. Objective
Urgency of Earthquake Directly underneath Tokyo
Distribution of seismic centers of earthquake of more than 5.0
Magnitude occurred during 1994-2003

Earthquake probability within 30 years is 70% (as of 2007).
The recent damage prediction expects wider affected area under anearthquake with seismic intensity of 6 upper (Japanese Scale).

Buildings along theEmergency
Transportation Roads Special Issues
in TMG
Huge damages in wide
areas (wideness/publicness)
Urgent implementation of
all the target buildings
along the road is needed(unity/ immediacy).

2. Regulation to promote Seismic Retrofit
Emergency Transportation Roads• It works as major arterial road for various persons andvehicles in daily.
• In case of emergency, it functions as lifeline/vital arteryfor evacuation, emergency rescue and fire fighting,transportation of emergency goods, and supporting
rehabilitation and reconstruction

WhatisSpecificTransportation Roads?

Emergency

It means the roads which are specially required to promote seismic
retrofit of the buildings along the road.

Total Length: apx.1,000 km

Outline of the Regulation Established byTMG
Specific Building along SETR includes;
1) Buildings of which their lot is attached to
the Specific Emergency Transportation
Roads (SETR).
2) Buildings build before new quakeresistance standards (come into force on
Shaded part is subjectJune 1, 1980).

3) Buildings of which their height is bigger
Road Center
than a half of the road width.

Obligations of the Owners of the Specific Building along
SETR are;
1) Report of the progress of seismic retrofit procedure (Obligation)2) Implementation and report of seismic diagnosis (Obligation)3) Implementation of seismic retrofit (by Effort) and Report (Obligation)

Q. Who is responsible for Seismic Diagnosis?
A. Registered Architects under Architects Law who isapproved to design the buildings such as First-classarchitect, Second-class architect, and Wooden buildingarchitect.
TMG is implementing the seismic retrofit projects
coordinating with the following three organizations.
• Tokyo Association of Architectural Firms (TAAF)• Japan Structural Consultants Association (JSCA)• Japan Aseismic Safety Organization (JASO)
