*TAISEI QUALITY® :
Our Group's activities for quality promotion are summarized into TAISEI QUALITY®. The Taisei Group employees are proud to dedicate to quality, and strive to earn the trust of customers and society.
Quality Policy of each Division
Building Construction Division
We established the “Construction Quality Management Standards” in April 1984 to realize quality assurance in the construction business and have promoted quality management according to a consistent assurance system encompassing the entire process from receiving order, construction to after-sales services.
Later, we obtained ISO9001 certification by 1997, and have realized quality management conforming to the certification. Upon transitioning to ISO9001: 2015, we positioned the “Construction Work Standards” established in 2008 as an equivalent to a quality management manual, and have ensured quality management by implementing workflow according to the Standards. Based on the current Medium-term Business Plan (FY2018-FY2020), the Building Construction Division has laid down a Quality Policy declaring that it will satisfy and win the confidence of customers by continuously providing high-quality construction products and related services to meet the needs of customers and society.
Civil Engineering Division
In order to provide high-quality civil engineering structures based on customer needs, we bring together our collective wisdom and organizational capabilities as a general construction company and pursue the quality and service that will satisfy our customers by faithful and prompt cooperation of all parties involved in the construction project.
To further improve customer satisfaction, we continuously improve the effectiveness of our quality management system for more effective operation.
The Engineering Division was established in 1968 as the first engineering division among general construction companies in Japan and has the longest history and a proven track record spanning more than 50 years. For more than 20 years since it obtained ISO9001 certification in 1996, the first among all divisions in Taisei Corporation, it has engaged in quality management activities, realizing customer needs and building the trust of many customers.
In 2020, the Engineering Division switched to the same certification body as the Building Construction Division and Design Division, and further continues to take great strides as a division capable of satisfying requirements consistently from project planning to design and construction.
In order to achieve customer satisfaction, the Engineering Division upholds “continuously providing high-quality facilities and services that satisfy customer needs” as its own quality policy under the corporate Quality Policy and engages in activities to improve quality by establishing specific principles of conduct as follows:
- Precisely understanding customer needs and providing the right solution
- Fostering human resources who can offer advanced services
- Ensuring compliance with laws, ordinances and regulations
- Appropriate operation, continued maintenance and management of the quality management system
The Design Division obtained ISO9001 certification in March 1997 for both the corporate Design Division and design departments in eight branch offices combined, allowing us to establish a mechanism to ensure design quality in all departments across the country. Since then, we have built a mature quality management system by continuously following the PDCA cycle.
Every year, we continuously review the project processes in cooperation with the sales departments and the Building Construction Division and reflect the results in the Construction Work Standards and the quality system of the Design Division.
While implementing integrated quality management together with the Building Construction Division from upstream to downstream, we established the Taisei Corporation First Class Architect Office for Construction Supervision in 2016, and are supervising construction work with an independent authority.
With the rapid adoption of information and communication technologies and associated changes in the way we work, new risks are emerging and system review is becoming ever more necessary.
The Design Division obtained BS7799 (now ISO27001) in June 2002 as the world's first construction industry player to obtain a certification for information security management systems. It promotes comprehensive risk management through ISO activities in the areas of quality, environment and information security.
Nuclear Facilities Division
The quality policy of the Nuclear Facilities Division under the corporate Quality Policy is “to improve customer satisfaction through the provision of design, investigation, research and development services, verification tests and technical support for nuclear-related facilities and to contribute to the safety, reliability and environmental preservation of nuclear-related facilities.”
The Division is capable of meeting quality assurance needs of individual customers including power companies by conforming to the “Rules of Quality Assurance for Safety of Nuclear Power Plants: JEAC4111” (The Japan Electric Association), “Guidelines for Quality Improvement of Analysis Related to Application for Permits and Approvals for Nuclear Facilities” (Japan Nuclear Safety Institute), and “Quality Assurance Requirements for Nuclear Facility Applications (NQA-1)” (The American Society of Mechanical Engineers: ASME), etc., as necessary.

Productivity Improvement Initiatives
KPIs JPY 83 million productivity (net sales/number of employees)
Taisei Corporation utilizes T-CIM® and BIM to manage the information obtained through planning, design, construction and operation. We also established the DX Promotion Committee in fiscal 2020, and build a structure to work on DX on a company-wide basis. We provide the best service and solution to each customer, while reviewing our business processes by visualizing performance with productivity per person (sales/number of employees) as an indicator to raise each employee's awareness on productivity. In this way, we are working together as one group to improve productivity.
T-CIM® is our proprietary system that integrates a construction system utilizing Information and Communications Technology CIM (Construction Information Modeling) proposed by the Ministry of Land, Infrastructure, Transport and Tourism, with attribute information associated with a 3D model of each construction project.
BIM, an abbreviation for Building Information Modeling, is a construction information database which links a 3D building model created with a computer and attribute information including the specification, layout and cost of building components and equipment.
Leveraging ICT to Realize Immediately Effective Productivity Improvements
Since FY2017, Taisei Corporation has been pursuing an initiative aimed at productivity improvement and technological innovation based on ICT. We are striving to implement this initiative company-wide, with approximately 80 employees responsible for its promotion assigned to the Head Office and branches. Apart from utilizing T-CIM® and BIM for managing information obtained through planning, design, construction and operation, we make most of ICT as a measure to raise production capacity at construction worksites in the most efficient and immediate manner.
Specifically, mainly at worksites, we steadily introduced a network called “Worksite Net,” which facilitates information sharing between personnel involved in projects, both internal and external, as well as Field Pad®, which helps improve the efficiency of operations such as viewing and recording construction management information.
Field Pad® is used for overall construction management operation including the storing and reporting of construction progress photos at worksites, contributing to shortening work time, and increasing productivity.
Innovation of construction production system with T-CIM®
(Civil Engineering Division)
Since 2014, the Civil Engineering Division has been developing the T-CIM system that aims to improve productivity and quality at construction sites. Construction Information Modeling/Management (CIM) promoted by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) since 2012 is a technology that links a 3D model with attribute information including construction member specifications. Our proprietary T-CIM system, however, is characterized by the fact that it does not require 3D modeling.
There are several types of T-CIM systems, including T-CIM /Concrete that supports general concrete works and T-CIM /Tunnel that supports specialized construction works, as well as other types of T-CIM systems specialized in different works related to earthmoving, dams, shields, bridges, railways, marine engineering, soil decontamination and others. All of these systems allow users to view the final as-built image, quality information and progress information from anywhere by utilizing cloud computing.
In particular, the T-CIM/Concrete system manages information ranging from mixing of fresh concrete* to concrete placing by cloud computing over the Internet. The system allows users to view the progress status on a real-time basis and is being deployed to not only civil engineering sites but also construction sites. The effectiveness of the system has been confirmed by the MLIT's Public/Private R&D Investment Strategic Expansion Program (PRISM) in FY2018/FY2019/FY2020 and received high acclaim.
* Fresh concrete refers to soft concrete mixture before solidification. Mixing is the process to blend the ingredients of concrete so that they are evenly mixed.
KPIs 100% customer satisfaction
Building Construction Division
In the Building Construction Division, each branch conducts a questionnaire survey on customer satisfaction. The survey questions are on a five-point scale, and include those on workmanship, usability, and worksite office management during construction. If there are any low scoring items, we analyze their causes, establish countermeasures and reflect them in post-construction review meetings and other opportunities for better understanding. In this way, we aim for greater customer satisfaction.
Civil Engineering Division
The Civil Engineering Division sets customers' evaluation scores on the construction work as an indicator of customer satisfaction. Adding to that, the division conducts customer satisfaction interviews.
Each branch reflects the research results in the postconstruction review for further improvement. Going forward, the Head Office and branches will continue working as one for better customer satisfaction.
Building Meister System / HQ Staff's Coaching System
(Building Construction Division)
The “meister system” and the “HQ staff's coaching system” were put into practice from 2009 as part of the “TAISEI QUALITY” activities to promote the acquisition of skills and expertise in order to securely pass along our technologies and know-how, with the aim of strengthening productivity and the construction management system.
The employee's appointed as meister and the executive staff of the Building Construction Division, with abundant on-site experience, make actual visits to the sites and provide education and guidance on the skills and quality/site management and other capabilities through OJT, in close contact with the young and middle-aged employee's.
Educational Supporter System
(Civil Engineering Division)
Under the “educational supporter system” introduced in 2009, educational supporters appointed from among employee's with experience as construction site managers check the progress of OJT education of young employee's and provide support and guidance. The Civil Engineering Division strengthens employee's management capability to reinforce productivity and the production system, in addition to “improvement of the working environment” and “securing of human resources.” Specifically, under the goal of “increasing the employee's capabilities at production sites,” the “On the Job Training (OJT) education” is introduced and operated to enhance the capabilities of process management, design, estimation, negotiation and action, among others.
Promoting Female Participation through Kensetsu Komachi
Taisei supports the “Kensetsu Komachi” project of the Japan Federation of Construction Contractors in order to boost the activities of female engineers as one part of its effort to promote an active role for women in construction workplaces. Since 2014, Taisei has provided opportunities for dialogue between executives and female engineers in its Civil Engineering and Building Construction Divisions in an effort to create a workplace environment in which women can thrive.
Through activities such as this, Taisei works to incorporate the perspective of women in its in-house operations in the belief that this will create new value. Taisei also participates as a member of the Kensetsu Komachi Committee established by the Japan Federation of Construction Contractors and works to collect data on construction companies that are engaged in progressive initiatives. We will continue to work to create a workplace environment in which the talents of female employees are recognized and manifested.
The Kensetsu Komachi Empowerment Award was established by Nikkenren with the objective of hiring and retaining workers, advancing diversity, and renewing the image of the construction industry for greater female participation in the industry.
Appropriate Information Management
Robust Customer Information Management
To manage information required by customers based on the Guidelines for Managing Customer Information, we set security levels according to the confidentiality level of each project, transmitting information to the relevant in-house departments, and implementing appropriate customer information management.
Improving Information Security Levels across the Construction Industry
We aim to improve information security levels across the whole construction industry, not only Taisei Corporation, by providing partners and other companies in the same industry with free access to a personal computer security diagnostic website jointly developed with a security vendor.
