Civil Engineering
Developing Strategic Technologies to Provide High Added Value

Hiroyuki Kimura

Hiroyuki Kimura

Executive Vice-President and Representative Director;
Chief of Civil Engineering Division and Deputy Chief of Corporate Planning Office

In the Civil Engineering Division, we construct various infrastructure facilities in accordance with the changes in the times and business environment. To respond to these diverse needs, we pour our efforts into developing strategic technologies. To further strengthen this business infrastructure, we promote technologies for constructing underground structures, technologies for high-speed construction of dams, maintenance and renewal technologies such as replacement of bridges, information sharing technologies using iPads, and CIM* initiatives, etc.
As a result, in 2013 we completed construction of the Metropolitan Expressway Central Circular Route Shinagawa Line in a speed with long distance excavation that was unprecedented in the world with a sole shield machine, the Aokigawa Bridge on the New Tomei Expressway which was awarded as a design and construct contract, etc. We overcame various problems based on our extensive construction experience and reliable technologies, receiving high evaluation from customers.
We are also expanding our business field in the world. In the Bosphorus Straits Crossing Railway Tunnel project which was completed in 2013, we succeeded in directly connecting different types of tunnel, which was the first in the world. Our overall accomplishments in providing good construction processes and quality by utilizing advanced technology and undertaking difficult construction was highly evaluated, and we received many awards such as the Japan Industry and Technology Award-Prime Minister's Award, and the Japan Society of Civil Engineers' Technology Award.
Using this technology and know-how we contributed to the maximum extent to the recovery and restoration from the Great East Japan Earthquake in 2011. As a part of the works, we are engaged in many social infrastructure restoration projects, such as radioactive decontamination work ordered by the Ministry of the Environment and local governments, related works to Fukushima No. 1 Nuclear Power Plant, group relocation for disaster mitigation for UR Higashi Matsushima and Kesennuma, etc.
In the future we intend to continue to enhance our design capability, pass experience to the next generations, and develop our technologies.

Building Construction
Bringing Together our Building-related Technologies to Exhibit our Total Capability

Yoshiyuki Murata

Yoshiyuki Murata

Managing Executive Officer, Chief of Architecture & Engineering Division (Integrated);
Chief of Building Construction Division;
Deputy Chief of Corporate Planning Office

In the Building Construction Division, we undertake the construction of various types of facilities, such as offices, housing complexes, as well as accommodation, commercial, medical and welfare, nuclear power, production, traffic, education, sports, theaters and other facilities.
The strength of the company's Building Construction Division is its total capability. We place great store on bringing together the various departments such as design, procurement, environment, engineering, etc., and organically combining our advanced technologies and extensive know how to realize innovative ideas as buildings having quality and functionality. Also, based on the results, we develop new technologies that will be useful for the future.
Development of the company's unique advanced technologies is proceeding, and some of the construction technologies that we are proud of include the group of ultra high strength concrete technologies “T-RC+”, the vibration control system “TASMO” for high rise RC buildings, seismic isolation technologies such as urban-style small displacement seismic isolation, etc. Precast concrete is produced by the company's PC factory at Namegawa, Chiba, providing a system that enables a stable supply of products produced with advanced quality control. In addition, great freedom of design and shorter construction time can be achieved by applying precast concrete to various projects, utilizing the characteristics of the PC members. In overseas projects also, we have been expanding mainly through large projects in which we can exhibit our total capability, as represented by the Noi Bai International Airport Terminal Building in Vietnam.
With the prospect of continuing demand for building due to restoration from the earthquake disaster, strengthening the national land, holding the Tokyo Olympics and Paralympics in 2020, etc., we are actively working to solve the shortage of engineers, which is a nationwide problem. Employees are encouraged to improve their skills through education and training for young staff members and acquiring qualifications, etc. Also, measures such as formulation of a rational work flow on construction sites, promotion of a system of appropriate wages for skilled construction labor and registration in social insurance, etc., are being implemented with the cooperation of our partner companies (cooperating companies), in particular Souyukai, to speed up the establishment of a production system appropriate for modern times.

Real Estate Development
We Undertake Everything from Project Support to Urban Renaissance with our Accumulated Know How and the Group's Power

Katsuyuki Kanai

Katsuyuki Kanai

Managing Executive Officer;
Chief of Urban Development Division

In the Development Division, we provide solid support for our customers' projects from the project planning stage by using our urban development know-how such as offering profitable development plans, support for discussions with authorities on urban planning and obtaining development permits, and coordination with stakeholders. In redevelopment, which is the company's strongest field, we are involved in about 20% of shopping street redevelopment projects throughout Japan, and our achievements in PFI are also top class. Also in recent years, the demand is increasing for refurbishment of aging buildings that were constructed during an earlier period of high economic growth, for which we propose to customers more efficient facility development, by obtaining a higher floor area ratio or relaxation of building regulations, etc.
Besides these development business activities using our development know-how, we undertake development projects of our own as project promoter. We undertake a wide range of development projects ranging from office buildings such as Ochanomizu Sola City and Otemachi Tower, to Taisei-branded condominiums in collaboration with our subsidiary Taisei-Yuraku Real Estate Co., Ltd. The greatest strength of the Development Division is that we have a company-wide support system for operation and management after completion, as well as the construction, and not only for our own development projects.
It is considered that there will be a step up in urban and infrastructure development for the 2020 Tokyo Olympics and Paralympics, so we need to deal with the problems of the city, such as supporting disaster resistance.
