Response to disaster risk

Total Partner for Risk Measures

As the importance of building for a safe and secure society is debated again, attention is focusing on the concept of "resilience." Resilience is the capacity to rapidly return to the normal level after damage due to a disaster.
Taisei Corporation takes it one step further, and perceives that it is necessary for resilience to include "capacity for prevention" in addition to "capacity for recovery." It is considered important to prepare in advance to minimize disaster damage as much as possible, as well as to recover functions that have been reduced or stopped in a short period of time.
In order to maintain the function of a building or equipment when a disaster occurs, it is important to formulate a facility strategy in accordance with the customer's management vision, and to implement (PDCA) FM activities* that strongly reflect a specific plan.
As shown in the diagram below, operating the cycles of both the customer's management activities and the FM activities assists in deepening the risk communication of the two, and by developing and providing various risk measure technologies at the planning stage, the customer's resilience is increased.

The Resilience of Society is Raised by a Shared Recognition of Risks

Earthquake risk is an unavoidable major natural disaster risk in Japan. In order to increase resilience, it is necessary that society as a whole has a shared recognition of the risk. We operate the website "Taisinnet*" as an information platform for measures against earthquakes, as a place for sharing risks from this point of view, and we hold public seminars at various times throughout the year.

Optimizing the Ideas of both Facility Managers and Users

In order to use a facility for a long time, it is necessary to optimize both facility strategy and policy, which vary depending on the business environment, and the FM requirements based on the needs of the facility users. In order to realize this, we assist not only with risk management, but also venture into the field of BCM,* and assist in optimizing ideas from the management point of view and the ideas of the facility users.

* Business Continuity Management

Various solutions for achieving business continuity

Taisei Corporation has prepared various solutions to contribute to building a highly resilient society that can rapidly recover, by preventing disasters and minimizing damage, based on our wide-ranging experience and researches. Here, we introduce highly practical technologies and know-how corresponding to disaster risks, to match a customer's individual business strategy.

"T-Buffer" to Fend Off Tsunami Risk

The tsunami protection measure building "T-Buffer" has been developed based on tsunami simulation technology. The structural columns on the outer periphery of the building form a "buffer zone," which prevent damage to the life critical core structure by absorbing the wave pressure of the tsunami and the impact force of the debris, and by using waterproof doors, etc., in the wall openings of the core, the building can function as a tsunami shelter. In November 2012, a tsunami protection measure deep freeze cold storage facility (see MASKAR P17) that is capable of withstanding a level 1 tsunami (the level of tsunami that is postulated to occur at a frequency of once in 100 years) was completed in Onagawa Town, Miyagi Prefecture, partially realizing this concept.

"T-Respo Structural Method" Protects Against Long Period Seismic Motions

It is said that large scale predicted earthquakes such as the Tokai, Tonankai, and Nankai earthquakes, etc., will have long period seismic motions. There is a possibility of resonance between some ultra-high rise buildings and long period seismic motions, and there are concerns over the occurrence of damage to system equipment if large oscillations continue for a long period of time. Taisei Corporation has developed the "T-Respo Structural Method" as a measure against long period, long duration seismic motions. This reduces the oscillations during an earthquake without reinforcing the columns or beams by using displacement dependent type oil dampers, etc. This was introduced to the Shinjuku Center Building in 2009, and its vibration control effect was verified in the 2011 Great East Japan Earthquake.

Seismic Risk Management Taking the Order of Priority of Risk Measures into Consideration

It is necessary that measures against earthquakes apply a strategic order of priority. Taisei quantitatively evaluates the seismic risk of a building using the seismic risk method (SRM). The building under consideration is surveyed, damage to the building itself or to the system equipment is postulated, and the amount of the predicted damage is calculated as the seismic risk. A program has been developed that is capable of simply performing this calculation on a personal computer. In this way, material is produced for making decisions, such as where in a facility should be strengthened in priority, and what strengthening method should be adopted, which leads to seismic measures having a high investment affect.

"T-RESQ F" for Support of Emergency Response

"T-RESQ-F" (Taisei Real-time Earthquake Disaster Prevention System) is technology for shutting off equipment in an emergency within an industrial facility before the earthquake oscillations start, used in combination with the Japan Meteorological Agency's emergency earthquake warnings. Seismometers are installed within local sites such as factories, etc., and customization is carried out taking into account the ground of the site and the characteristics of the building, based on the accumulated seismic waves that have arrived and technology for analyzing the building structure. By predicting the size of the oscillations with high accuracy, it is possible to take rapid and immediate response to an emergency by automatically shutting down the equipment. This strengthens the response to inland earthquakes for which the emergency earthquake warning may not be on time.

"Rack Vibration Control" for Rapid Restoration of the Supply Chain

In the Great East Japan Earthquake, automated warehouses that are logistic center for distribution were subjected to damage. Even though the racks themselves did not suffer much damage, there were many cases of damage to parts of the rack transport systems resulting in the goods falling off the racks. The supply chain of products was also affected by the long term stoppage of automated warehouses. To solve this problem, in December 2012 a rack vibration control unit was developed to reduce the occurrence of goods falling off in automated warehouses. The unit is effective even in strong earthquakes of seismic intensity 6 (Japanese scale). The unit can be simply installed in existing automated warehouses at low cost and in a short period of time, and operations can continue immediately after an earthquake without stoppage.

Innovation in Logistics and Creating Highly Resilient Facilities

When Taisei plans a facility, the optimum measures are proposed from the aspect of business continuity, considering not only the building and the building equipment, but also the production system. Currently we are working on further strengthening our facility diagnosis method in conjunction with a university.
Also, we devise the most appropriate schemes for logistics, not only for productivity and economics, but also for a high capacity to recover operation after a disaster such as an earthquake, utilizing our capabilities derived from our extensive experience of logistics facility construction and logistics consulting, with an emphasis on the stable supply of products and materials in the supply chain. In addition we have entered the 3PL* business in which we take responsibility for logistics operation, achieving major efficiencies and cost reductions in transport through "joint logistics."
Logistics is a strategic task that is important for company management. Through diff erentiation of business con tinuity in the logistics area, a company gains competitive advantage, and produces a new aspect of management. We propose various innovations in logistics, to construct highly resilient facilities.
