Building lives vary greatly. They are long; lasting from several decades to over a hundred years. The work of Kumagai Gumi is not just to construct buildings. We are involved from building plan creation through the design, construction, operation, maintenance, and remodeling phases up to and including management utilizing our extensive experience in solutions technology. We continue working together with clients before construction, during construction, after construction, and into the future.


Renewal
Renewal work faces many restrictive conditions and thus requires more advanced comprehensive technical ability and broad consideration than does new construction.


Solutions
The ability to solve a variety of problems related to the construction business. Kumagai Gumi has the experience and know-how nurtured over many years as a general contractor.


Maintenance
Much social infrastructure is approaching the time when renewal and large-scale repairs are required due to deterioration over time. The development of technology for safely, accurately, and efficiently inspecting social infrastructure is a top priority.


Management
Kumagai Gumi was the first company in Japan to begin working on overseas BOT projects (build, operate, and transfer) and the extensive experience gained overseas doing this is being utilized for private finance initiatives (PFI) in Japan.
