wi l l f ur t h er ac c e l er at e t he ef f or t t o r ea l i ze t h e c o nc e pt of “ R e g io n a l l yAllied General Contractor”, aiming to solve issues in the local construction industry.
〔Issues in the local construction industry〕
While the government's “National Resilience Initiative” is expected to result in a larger
budget for local regions, the local construction industry, which will be responsible forthese projects, is facing a shortage of engineers and an imbalance in orders by region.
Although the Ministry of Land, Infrastructure, Transport and Tourism has started tocultivate the local construction industry as a “local guardian” to support the Initiative,these issues are not easy to be solved by a single constructor.
〔The concept of “Regional Allied General Contractor”〕

In response to the above issues, UNICON proposes the “Regional Allied GeneralContractor” business model, in which companies with a substantial presence form
partnership to aim a new collaboration framework across the regions* to achieve highprofitability and high growth as a group.
Solving these issues across the regions, we will share the orders and resources torealize leveling of peak and off-peak orders and optimize the engineer’s allocation.
In addition, UNICON will be promoting recruitment activities to expand access toyounger generations and other groups to which individual group companies could not
sufficiently access. This initiative should result in the creation of local jobs thus further
contributing to the regions.
