Quality management system

Framework to promote quality management system at Haseko Corporation

※Quality Management System

Background to obtaining ISO certi cation

Haseko Corporation obtained ISO quality management system certi cation in Tokyo and Kansai regions in March 1997 and July 1997, respectively. In March 2018, we integrated the quality management systems in Tokyo and Kansai regions and have since been operating the integrated system.
Going forward, we will continue to engage in quality management activities.

Initiatives and ongoing improvement

Upon conducting quality management activities, we formulate a quality policy, in response to which each division sets quality goals and numerical targets and carries out the activities accordingly. The quality management system is checked by internal audit and external examination as to whether or not it complies with Haseko’s determinations including speci cation requirements, and whether or not it is implemented and maintained properly. Based on the results, the quality management system is reviewed and improved on an ongoing basis.
The days on which external examination was conducted and the number of matters pointed out in scal 2020 were as follows.

Construction of “resilient” condominiums considering the prevention and reduction of disaster

As Japan continues to be hit by large-scale typhoons and earthquakes, the call is growing for disaster-resilient housing.
This section traces Haseko Group’s measures against disaster through the years and highlights the activities of Disaster Resilient Technology Working Group aimed at promoting the “construction of disaster-resilient condominiums.”

Providing services under the Proposal of Hazard-resistant Condominium

In 2018, many residential homes were significantly affected by natural disasters including the Earthquake in Northern Osaka Prefecture and Typhoon Jebi (No. 21) which crossed the Kinki region. The Disaster Resilient Technology Working Group, which was established by the Haseko Group in the wake of increasingly severe natural disasters, has prepared and has been providing services based on the Proposal of Hazard-resistant Condominium covering exclusive and communal areas, essential services, as well as operation and management.
The Proposal will be actively made to properties inside and outside the Group for adoption to support residents both from the tangible and intangible aspects of the Haseko Group’s safe, secure and comfortable condominiums leveraging the advantages of collective living.

Development and introduction of the Smart Water Tank that utilizes rainwater efficiently

Haseko Corporation and Haseko Property Management Holdings Inc. have developed the Smart Water Tank as a disaster prevention and environmentally-friendly initiative and introduced it to RENAI Ichihara Yawatajuku (developer: Sohgoh Real Estate Co., Ltd.) and Branchera Yotsukaido-ekimae (developer: Haseko Real Estate Development, Inc.). This facility stores rainwater taken from the condominium roof and makes efficient use of the stored rainwater for watering plants during normal times to help preserve water resources, and in emergency situations, it can supply drinking water to residents for six days (three liters per person per day) by using the WELLUP emergency water purification system. In the future, we plan to install the Smart Water Tank as a standard specification for projects of over 200 units designed and built by Haseko Corporation.

Smart Water Tank concept

Adopting specifications and facilities suitable to a unique local environment

BRANCHERA NAHA AKEBONO PREMIST has adopted particular specifications and facilities that suit the climate of Okinawa. In Okinawa, where there is much rain coupled with strong winds, high watertightness is required of openings of buildings. For residential buildings such as apartments in particular, sash windows need to deliver a high level of watertightness to give residents a sense of security. BRANCHERA NAHA AKEBONO PREMIST uses high watertightness sash windows, which have achieved a watertightness of 1,500Pa, exceeding the level of JIS W-5 (equivalent to 500pa), so that the property can weather long hours of rainstorms such as typhoons.

"Three-piece set disaster prevention equipment" to secure post-disaster living necessities

The Haseko Group has long believed that it is important to not only ensure the basic performance of condominiums per se, but also develop the framework to secure the basic necessities of life for residents after a disaster has occurred. From such perspective, we became the first in Japan to adopt an emergency potable water generation system in a for-sale condominium in 2003, and have since been putting efforts into adopting and proposing the "three-piece set disaster prevention equipment"—which consists of an emergency potable water generation system, emergency manhole toilets and benches that convert into cooking stoves as disaster prevention facilities to secure post-disaster living necessities, i.e., water, toilets and fire—in for-sale condominiums designed and constructed by us.

Creation of New Values by Means of Condominium Renewals

It is said there are approximately 1,040,000 aged condominiums constructed under the former earthquake resistance standards (those of 1981 or before). Lack of aseismic capacity, aging buildings and facilities, aging residents as well as the question of how to renew condominiums have become social issues. The Haseko Group has established a framework to provide one-stop support for a variety of phases (including grasping of actual conditions through the evaluation of aseismic capacity, building diagnosis, and/or equipment diagnosis, deliberation of policies for rebuilding or life elongation considering the results of said evaluation and/or diagnosis, building of consensus between residents, design, and construction work) to cope with condominium renewals. The Group will create new values by coping with condominium renewals, making the most of its experiences in condominium construction, thereby contributing to the resolution of social issues.

The total number of condominiums repaired/renovated: 680,000
(Renovation work of over 10.00 million yen in and after 2000; as of the end of March 2021)
The total number of condominium buildings rebuilt: 37
(As of the end of March 2021; completed constructions)

Example of longer service life: Seismic reinforcement of condominiums currently housing residents
Development of Haseko Non-brace Reinforcement Frame Method

Existing condominiums with concerns over anti-seismic performance often have difficulty in obtaining seismic diagnosis and reinforcement work due to reasons such as “no budget for reinforcement work,” “no budget for diagnosis fees,” “lack of interest in seismic diagnosis,” and “lack of interest due to increasingly aging residents” (source: “Survey Results of Current Condition of Condominiums,” by the Bureau of Urban Development, Tokyo Metropolitan Government, March 2013). As efforts toward seismic reinforcement, the Haseko Group has been developing technologies to furnish anti-seismic functions on condominiums while continuing to house residents, in addition to seismic diagnosis and seismic repair designs and works. Recently we succeeded in developing the Haseko Non-brace Reinforcement Frame Method, a new unique seismic reinforcement method which allows works on a condominium while residents continue to live there, without compromising the view.
This seismic reinforcing method does not use diagonal braces that may obstruct the view but instead uses reinforcing puncheons, which allows reinforcing effects to be adjusted. Also, installing reinforcing frames consisting of wide flat beams, reinforcement columns, and reinforcing puncheons increases seismic capacity. Furthermore, although conditions apply, the reinforcement frames can be installed in middle floors, foregoing ground installations of newly installed frames as required in existing methods.
In the future, we will make the Haseko Non-brace Reinforcement Frame Method widely known as an option for existing condominiums which need to be reinforced for earthquake resistance and proactively make proposals combining other seismic reinforcement methods that are optimal for individual situations and requests.

Benefits of the Haseko Non-brace Reinforcement Frame Method

  • The view from the balcony is less compromised
  • Work is possible while residents continue to live there as in-unit work is not required
  • Lower cost than other existing reinforcement methods
  • Environmentally-friendly method as demolition and removal of existing buildings are kept to a minimum

Haseko's "renovation business"

Distribution of existing housing accounts for a lower percentage of the total housing distribution volume in Japan than in Western countries. The increase in vacant houses has become a social problem due to a mix of various factors, and one of its causes is the number of houses in stock exceeding the number of households due to the aging and shrinking population combined with the declining birth rate. Haseko Real Estate, Inc. is promoting the "renovation business," which involves purchasing a unit in a condominium subject to unit ownership and selling the unit again after renovating it. We will contribute toward the distribution of existing housing by increasing the asset value of homes through the business.

"Haseko's Premium After-sales Service"
After-sales service for perpetual and comfortable residency

Haseko Corporation has treated after-sales service as an important quality of condominiums. In 2008, we thus introduced Haseko's Premium After-sales Service (PAS) to get a grasp of the status of condominiums more accurately and take optimal action in a speedy manner by listening to our customers' opinions directly. In fiscal 2020, PAS handled 4,727 cases in the Tokyo region and 3,386 cases in the Kansai region, totaling 8,113 cases.

Back in the day, the common procedure was to receive a call via a condominium management company. With the introduction of PAS, customers' opinions are communicated directly to Haseko (i.e., the builder), allowing first-class registered architects and other staff with expert knowledge of condominiums to respond and thereby facilitate technicians' actions.

PAS not only serves as a call center, but also provides support from all angles so that the home can be used for a longer period of time, including the extension of the after-sales service period, the enhancement of periodic services, and the distribution of "Maintenance Handbook for Housing" and "Tool Kit for Maintenance." Furthermore, comments received at the call center and results of periodic inspections by the inspection team are shared at feedback meetings attended by the design, construction, and technological promotion divisions as well as the management companies. They are also reflected in properties undergoing design and construction. We hope to contribute to the safe and secure living of residents by adopting PAS in more properties in the future.

Haseko Community Owl 24 Center:
