Safe & Secure Services
Pursuit of Safety and Security
Thorough Process Inspections
To provide housing where people can live for a long time with peace of mind, MIRARTH HOLDINGS Group conducts stringent checks at the construction stage. We put great effort into ensuring thorough quality management, with our staff regularly visiting construction sites to inspect building structures and conduct checks within the construction process of hidden areas, foundations, and finishing.
Obtaining Housing Performance Evaluation Reports
Takara Leben obtains housing performance evaluation reports from third parties designated by the Minister of Land, Infrastructure, Transport, and Tourism to provide customers with greater peace of mind regarding their residences. To obtain these reports, we acquire performance evaluations at each stage of design on topics including earthquake- and fire-resistance, degradation resistance, energy consumption, and ease of maintenance. Five or more on-site inspections are carried out during construction, and a rigorous performance evaluation must be passed at the time of completion.
Earthquake- and Fire-Resistant Structures
Earthquake-resistant construction
In the construction of condominiums, we improve earthquake resistance by adopting the most appropriate construction method for the characteristics of the subsoil and its capacity to support the foundation. This includes the use of pile foundations, where strong piles are directly driven into the ground to the supporting layer, spread footing foundations, which provide support directly using firm subsoil, and seismic isolators, which disperse earthquake energy and dampen extreme, long-period building swaying.
In the construction of detached housing, we adopt wood-frame construction, which affords a high degree of design freedom and flexibility when adding to or renovating a structure in the future, together with a panel construction method that offers high durability and safety as well as good earthquake and fire resistance. We also employ as a standard feature a mat foundation method whereby a steel-reinforced concrete slab is laid underneath the entire wood floor to support the building, establishing a strong foundation using a high-earthquake-resistance and high-durability construction method.
Exceptional Fire-Resistant Structures and Soundproofing Performance
We use highly disaster-resistant materials in the construction of condominiums. Standards for fire resistance and sound insulation performance are set by law, and the concrete thickness of the unit boundary walls (walls separating dwelling units from each other), for which fire resistance and sound insulation performance are strongly required, is secured at approximately 180mm. In addition, fire and sound insulation measures are adopted for the piping in the pipe space facing the living room.
Selection of optimal structure and equipment
Not only the interior design, such as floors, doors, and plumbing, but also the interior structure of the building, such as ceilings and piping sections in pipe spaces, is customized for each property to suit the land and the customers who live there, combining the most suitable structure and equipment.
Accident Prevention Measures
Our Group is working to prevent occupational accidents at workplaces and construction sites.
Safety and Health Patrols
At Leben Home Build, which is responsible for condominium construction and related work, initiatives are taken to ensure safer construction sites through safety and health patrols conducted at least once a month. These patrols involve checking the implementation status of safety and health management measures, such as monthly and daily inspections and the assignment of qualified personnel, while also working to raise safety awareness through safety instructions and similar efforts.
In addition, a joint special patrol is carried out once every quarter, involving senior management and partner contractors. In December 2024, during the Year-End and New Year Accident Prevention Period in the Construction Industry,* representatives from six partner contractors joined in visiting three construction sites. The patrol focused on areas such as daily management, on-site organization, accident prevention, fall prevention, and machine-related hazard prevention. Actual site conditions and work practices were reviewed, and the implementation of appropriate countermeasures was encouraged.
- * Year-End and New Year Accident Prevention Period:
A safety initiative aimed at raising awareness during the busy fiscal year-end period, when multiple construction activities often overlap due to a rise in projects nearing completion. The campaign promotes accident- and injury-free worksites heading into the new fiscal year.
Safety Conventions
Our Group holds a "Safety Conventions" in order to further promote occupational health and safety management and raise awareness and knowledge regarding health and safety among those working at construction sites.
In June 2024, Leben Community hosted a conventions with the participation of 24 partner construction companies, during which lectures were given on daily safety measures. A representative from an insurance company also took the stage to introduce examples of claims related to damage restoration work and to exchange opinions on key points during construction.
Safety Instruction for Subcontractors
Leben Community, which handles repair work on condominiums, works with partner contractors to carry out work safely and with minimal impact on residents’ lives. When a large-scale repair project is approved at a condominium management association meeting, the company’s repair planning staff, construction supervisors, and members of a managers’ committee consisting of key construction workers gather at the site to check and review in detail the scaffolding, placement of temporary facilities (offices, restrooms, security doors, etc.), and safety measures before work begins.
Disaster Response
Crisis Management Structures in Leben Community
Leben Community has established solid crisis management structures to protect the safety and peace of mind of condominium residents.
Safety Management
Remote monitoring systems promptly alert a security company via telephone lines in the event of any abnormality in condominium facilities. If necessary, security personnel respond immediately. Through its inspections and staff training, Leben Community has established a system for responding appropriately in the event of an issue with elevators, firefighting equipment, or other emergency.
Responses to a Large-Scale Disaster
Following the occurrence of the Great East Japan Earthquake in March 2011, an emergency earthquake countermeasures headquarters was immediately established, and initial measures were promptly taken. During disaster recovery construction, we provided support from the perspectives of a management association, led by our commitment to speed, dependability, and sincerity and based on the expertise and skills we have developed through our equipment and repair experience. Following the Noto Peninsula Earthquake that occurred in January 2024, we conducted temporary inspections of common areas and responded to residents' inquiries at our managed properties in the affected areas.
Disaster Response
Disaster Preparedness Drills
Leben Community supports the safety and security of the community of residents in condominiums. It is not easy for residents, including the elderly and children, to properly use fire-fighting equipment in their condominiums or to evacuate quickly through the correct evacuation route in case of emergency. The company conducts disaster drills in cooperation with the management association as part of its safety measures.
The disaster drill held in December 2023 included evacuation drills along actual evacuation routes, hands-on instruction by an AED rental company, and on-site guidance by automatic fire alarm system maintenance and inspection company, confirmation of disaster toilet storage locations and distribution methods, and fire extinguishing drills using fire extinguishers by all participants.
HOTEL THE LEBEN OSAKA "Disaster Prevention Experience Mission Plan"
Since the Great Hanshin-Awaji Earthquake, the Great East Japan Earthquake, and other major disasters, awareness of disaster prevention has continued to increase each time. At HOTEL THE LEBEN OSAKA (opened March 2022), the Group's first hotel brand, Takara Leben is developing the "Disaster Prevention Experience Mission Plan" to provide an opportunity for families to learn about and discuss disaster prevention together. The plan provides guests with a simulated experience of a disaster by having them spend a day in an inconvenient guest room with no lighting, use disaster prevention goods, and eat preserved food. In the guest rooms, a booklet entitled "Disaster Prevention Mission 7: Let's Make Disaster Prevention Rules for Our Home" is available, and by completing the seven missions, such as "Decide on an evacuation site to meet" and "Think about disaster prevention goods for the family,” their own disaster prevention rule book will be completed, which you can take home and use. We plan to actively contribute to local disaster prevention and disaster education for children by distributing the booklet and inviting students to participate in the Disaster Prevention Experience Mission Plan at public institutions and schools in the neighborhood.
Dispatch of Registered Non-Life Insurance Appraisers to Disaster Areas
In cooperation with major insurance companies, Leben Community dispatched of our own appraisers from the Company to conduct a total of 24 damage appraisals for a one-month period starting from February 2024 in the Ishikawa and Toyama prefecture damaged by the 2024 Noto Peninsula Earthquake.
No other condominium management company has an appraiser on staff to perform damage appraisal and damage restoration work at the request of insurance companies, making this the first such initiative in the industry. A letter of appreciation was presented by a major insurance company in recognition of the company's significant contribution to the prompt payment of insurance claims to disaster victims.
The company will continue to expand its business domain beyond condominium management by providing damage appraisal and damage restoration work at the request of insurance companies.
