Quality Management

Basic approach of quality management

Since the founding of the company,the mission of Takenaka, as per the management philosophy, has been to "leave great works in the world and contribute to society," through "giving shape to the desires" of the company's clients. Therefore, with the corporate motto as the basic approach, the company painstakingly crafts each and every project as a work of art.

The social environment changes with time, and there is no end to the changes required in the functions and value of architecture. However, there is no change in the desire of Takenaka to produce rich architecture and towns for the next generation where people can live with ease of mind.

Therefore, based on the "Corporate Philosophy" "as a company with the business attitude of emphasizing quality, and gaining the satisfaction of the clients and the trust of society at large through new environmental creation," Takenaka carries out business with this principle set as the "Basic Policy of Quality Management."

TQM activity

Total Quality Management (TQM) activity

The "quality" in "quality management" does not just refer to the quality of the building, but rather refers to the quality of the entire corporate activity, which results in the creation of a high-quality building.

As Takenaka is continuously aiming to improve the quality of the entire corporate activity, the company introduced the system of Total Quality Management (first implemented in 1976 as TQC, and changed to TQM in 1996).

With TQM, as well as the quality requirements specified by the client, the company makes proposals with the anticipated requirements of the client, with the aim of improving the satisfaction of the client with regard to the entire lifecycle of the building.

Therefore, at Takenaka, improving the quality of each process in the planning, design, construction and after-care stages, and quality assurance activity of buildings using the "Genchi Genbutsu" (go and see for yourself) principle are set at the core of TQM activity.

This way of thinking is based on the same "master builder" way of thinking which has been passed down since the foundation of the company, is reflected in the company's "the design-build contract method" which provides the full strength of the company, and is used the same in various project styles.

Quality process

The basic approach to the company's quality assurance activity is "to provide the quality of a product that can be orderedwith ease of mind by the client, and which will provide ease of mind, satisfaction, and pride to the client from the planning stage to a long period after construction is completed."

To realize this, quality assurance activity procedures are standardized in the "Quality Assurance System" through all the construction processes. TQC was implemented in 1976, and in order to meet the requirements of the times, and to promote the use of the system, modifications were made in 2009 in the pursuit of even better quality assurance activity and with the aim of streamlining the business

Also, seven main and branch offices acquired ISO9001 and ISO14001 certification, and so quality assurance is deployed with these ISO management systems in the day to day quality assurance activity.

The outline of the quality assurance activity processes with regard to the lifecycle of a building is shown below.

  • First, the company fully grasps the requirements of the client
  • These requirements are put together in the "quality being aimed for," and are reflected in the design drawings.
  • Honest effort is used to produce the "quality being aimed for" at the work sites, and is evaluated as the "quality in accordance."
  • Quality assurance activity continues after completion of construction, with after service dutifully carried out according to the operation conditions of the facility.

In these processes, the planning stage, the design stage and the construction stage are called "phases." There is a system of thorough process management and foolproof testing (phase gate) in each phase, and the project work is carried out after each step with the consent of the client.

Basic approach of quality management

Takenaka first implemented TQC is 1976, and changed the name to TQM in 1996, promoting the system with the aim of improving the quality of the overall corporate activities.

With the aim of TQM becoming firmly set as the corporate constitution, Takenaka is practicing TQM activity as one with the business.
