Building Construction

Continuing to develop technologies and exercise true craftsmanship

We provide all types of buildings such as offices, condominiums, commercial facilities, factories, hospitals and schools that meet diverse needs including reduced environmental load and energy conservation, comfort and convenience as well as seismic resistance and disaster readiness for securing business continuity.

We have completed many historically and culturally symbolic projects, such as Tokyo Central Station (currently Tokyo Station), Japan World Exposition (Theme Pavilion), Roppongi Hills, TOKYO SKYTREE®, and Toranomon Hills.

Business Strategies

We will work to expand orders in growth areas including the tourism, medicine, environment and renewable energy fields, as well as new industrial domains such as aerospace and marine. We will bolster our ability to make proposals and compete in sales, design, construction and maintenance and management according to building life cycles. Our focus will be on winning construction projects likely to deliver higher added value, such as engineering, smart city, and renewal work, as well as buildings requiring technological development capabilities including smart factories and next-generation data centers.

To improve productivity, we will promote open innovation, teaming up with venture companies, universities, research institutions, and other entities possessing cutting-edge technology. By organically linking innovative technology with our technologies and production expertise, we will work to develop new technologies that facilitate quality, safety, energy conservation, and efficiency. In addition, we will promote integrated use of BIM from planning and design to construction, maintenance and management throughout the Group, targeting even higher productivity. To secure production capacity, we will improve the work environment including by creating a climate conducive to taking vacations and introducing the health monitor system Envital™ . At the same time, we will support the development of multi-skilled workers and hold joint company introduction seminars with our suppliers.

We will remain committed to providing customers with safe, secure buildings incorporating the latest technology, while passing on the expertise we have gained through over 120 years of exercising true craftsmanship to the next generation.
