Risk management

Taking a PDCA cycle approach to risk management

Risk management structure

Each fiscal year, the Risk Management Committee (Chair: CEO) makes decisions on key risk management items for the entire company and takes appropriate steps to ensure each section incorporates these decisions into its business plans. Alongside these efforts, the Committee monitors the status of risk management by function at all head office and business divisions as well as at Group member companies; issues instructions for appropriate corrections and improvements; and addresses emerging risks. In this way, through the companywide deployment of key risk management topics, the Committee seeks to promote risk management. Our commitment to risk management based on the Plan-Do-Check-Act (PDCA) cycle is thorough and ongoing.

Information Security Initiatives

Based on the established Information Security Guideline and the accompanying information security management structure, Shimizu has taken a range of initiatives to improve security levels. This has included security enhancement around the company’s IT infrastructure, provision of educational contents regarding information security, and raising awareness about policy/guideline revisions.

Shimizu aims to raise awareness of information security amongst each and every one of its employees through initiatives such as the targeted threat prevention activities we started in FY2013. Furthermore, Shimizu continuously works with specialty contractors whom we collaborate with on construction projects to strengthen information security management.

Business Continuity Plan (BCP)

Basic Policy

In cases of natural disasters such as major earthquakes or other crises that may pose major damage, our mission is to secure the safety of citizens residing in areas affected by disaster and to preserve the foundation for living and the foundation of society. In our Business Continuity Plan, we focus on promptly preserving our workplace and facilities, supporting the recovery and restoration of the affected areas and supporting our customers to restart their businesses as quickly as possible.

In order to act promptly under such circumstances, our individual employees must understand their roles and act independently and responsibly. Additionally, we must prepare to be able adapt to new situations and quickly reform our corporate structure. In accordance to the points above, our BCP policy is established as below:

BCP Policy

  • Prioritize ensuring and confirming the safety of our workers and their family
  • Share the conscience of social and local contribution throughout the company
  • Preserve affected facilities, workplaces and facilities that are used by the company
  • Create a structure that allows workers that are involved in preservation activities to act independently and responsibly

Identifying disasters and estimating potential damages

In consideration of the studies by the Central Disaster Management Council’s “Specialized research committee to counter earthquakes that occur directly under capital Tokyo”, we are estimating major damages that will be done by the worst case scenario which will be the “Northern Tokyo Bay Earthquake”. The conditions and estimated possible damages of this specific earthquake are as below.

(The days within the parenthesis are the number of days that will be needed for complete restoration of the written situation)

Improving disaster prevention activities in partnership with communities

In the event of a major earthquake, forecasts indicate roughly 300,000 people will be unable to return home from Tokyo’s Chuo Ward, where the Shimizu head office building is located. Under these conditions, at Chuo Ward’s request, the head office building would serve as a regional disaster center and provide space and temporary accommodations for those unable to return home. Shimizu regards these regional disaster center functions as central contributions to local communities and is currently working on a system to deploy these functions effectively in the event of an emergency. In cooperation with Chuo Ward and other companies, we plan to help develop an area-wide disaster prevention system based on mutual support and mutual aid.
