In order to tackle the challenges mentioned above, Zenitaka decided to build a system that could improve the safety of tunnel construction as well as reduce the amount of power consumed. If a worker forgets to flip his or her name label when entering or exiting from the tunnel, management cannot be performed effectively. The workers themselves then flip the name label to the appropriate side when entering or exiting from the work site to indicate whether or not they are working inside the tunnel at any given time. Specifically, red labels with white reverse sides that bear the workers' names on both sides are displayed at the tunnel work site entrance. Even now, tunnel construction sites often use a 'name label' system for managing entry into the work site. Safety, was also not being managed very rigorously. In other words, we needed to be able to visualize the amount of power being consumed. In order to tackle the issue of reducing power consumption, it was first necessary to obtain an accurate breakdown of how much power was being used in each particular area. However, even in these cases, the devices only allow the total volume of power consumption to be ascertained, or they may issue warnings to prevent the contracted volume of power from being exceeded. Sometimes, corporations install demand-monitoring equipment to help curb the maximum power demanded. In many cases, the exact amount of power consumption is only ascertained when the bill from the power company becomes available. Despite this, the amount of power consumption is generally not tightly managed. This is because there are many kinds of electrical equipment being used day and night, including construction machinery, construction lighting, and ventilating fan. Mountain tunnels construction requires a massive amount of electricity.

These issues are 'improving safety' and 'reducing energy consumption'. Within these areas, there presented two issues that have always persisted in regard to the construction of mountain tunnels. The Zenitaka Corporation ('Zenitaka') has two major business areas: its architectural business focuses on structures such as government buildings, office buildings, and commercial facilities, while its civil engineering business is targeted at structures such as tunnels, bridges and dams.
