Safety diagnosis

SR identifies physical and functional defects in railway facilities and conducts investigations, measurements, and evaluations of structural safety and the causes of defects. We promptly and appropriately take measures and propose repair/reinforcement methods to ensure the functionality and safety maintenance of the facilities, thereby preventing accidents and disasters. SR strives to enhance the effectiveness of structures

  • Facilities/Bridges and Tunnels/Repair Field Performance Evaluation

Request and Project Progression

  • a. Client's Request: SR listens to the requests from the client, understanding their needs and requirements.
  • b. Understanding the Purpose of the Investigation: SR comprehends the purpose and objectives of the investigation.
  • c. Determining Investigation Level and Scope: SR determines the level of investigation and the specific items and scope to be covered.
  • d. Submission and Finalization of Cost Estimate: SR prepares and submits a cost estimate for the project, which is then finalized.
  • e. Writing the Contract and Contract Agreement: SR prepares the contract document and ensures the contract is officially established.

On-site Investigation (Building Inspection and Diagnosis)

SR visits the site directly to conduct measurements and inspections.

Preparation of Investigation Report

SR compiles and analyzes the data collected during the on-site investigation and prepares a comprehensive report.

Reporting of Inspection and Diagnosis Results

SR prepares an inspection report, which is then bound into a booklet and submitted to the client.

Total Facility Management Service

SR provides a comprehensive facility management service, including regular inspections and precise diagnostics, to identify safety management and disaster risks. From inspections to ongoing management, SR ensures the monitoring and assessment of various aspects related to facility maintenance and safety.
