Outline of Interim Report on the Future State of Maintenance and Renewal of Social Infrastructure

Aims

The report presents the findings of the Social Infrastructure Maintenance Strategy Subcommittee (established July2012) of the Technical Subgroup concerning appropriate basic approaches to strategic maintenance and renewalof social infrastructure and measures that should be taken by MLIT and other agencies given the current state ofmaintenance and renewal and related issues.

I.

Current state of maintenance/renewal and related issues





Socioeconomic situation and action to dateCurrent state of MLIT-controlled facilities and issues
Technological progress to date and challenges
Current state of maintenance and renewal by local public bodies and related issues
Issues concerning future cost projections for maintenance and renewal
Current state of systems and structures, and related issues

II. Basic approaches to maintenance and renewal in the future
9 basic approaches identified to ensure human benefits of social infrastructure are properly preserved for future
generations
 Institute standards, organize pace-setting initiatives involving central government-administered facilities, and support local
public bodies, etc.
 Activate provision of information to promote public understanding and cooperation
 Improve quality by taking advantage of renewal opportunities, etc. to enhance lifestyles and environment and build

III. Priority measures for strategic maintenance and renewal
Proposed specific priority measures for MLIT and other agencies to implement to surmount challenges presently faced

2. Measures to ensure systematic maintenance and renewal Adopt maintenance and renewal approaches that emphasize preventive maintenance,
improvement of performance and functions, consolidation and efficiency improvements, etc.
 Perform sequentially related processes (inspection/diagnosis – assessment – planning/design –repair, etc.) following PDCA cycle
 Plan from long-term perspective
 Secure funding for maintenance and renewal
 Enhance organizations/institutions and develop human resources

1. Measures to reliably and accurately monitor

soundness of facilities, etc.
 Establish mechanisms to reliably and accurately
monitor soundness of facilities, etc.
 Compile information and development of facility“health records”
 Disclosure information on soundness of facilities,etc. and response guidelines

3. Measures to raise maintenance and renewal levels
