1. 1．Development Background

   These days, in the construction industry, labor shortages due to aging skilled engineers and architects and the decrease in the number of construction workers have become urgent issues. Even for measurements, which are indispensable for construction sites, there are many tasks that require refined skills and abundant experience, and it takes a lot of personnel and time at the construction site. In addition, in the supervision work, it is difficult to give instructions in real time with conventional measurement methods, and it takes a lot of time because instructions are given after confirming the measurement results.

   For these reasons, we have developed this system to improve these issues and improve productivity in construction works. (Figure 1)

2. 2．System Overview

   This system uses Wi-Fi (wireless LAN) to display the accurate information in real time on the mobile device used by the construction worker. On the mobile device, the position information (horizontal and vertical) of the steel frame is displayed in figures and numerical values using the function developed independently (Figure 2).

   Moreover, in the conventional measurement method, two devices are needed to transmit the position information of the steel frame to the construction worker by radio; however, with the TATEKATA KING System, measurements can be performed by one person and just one measuring device, so the need for radio communication is eliminated.

   The measured information can be shared not only by the measurer and the construction worker, but also by the construction supervisor at the same time. Therefore, it is possible to construct the high-precision erection with no time lag.

3. 3．Advantages of TATEKATA KING

   ①Easy and reliable construction accuracy

   The measurement data is displayed on the monitor in real time. The operator can adjust the construction position while checking the monitor and as a consequence, the construction accuracy can be secured more easily and reliably than before.

   ②Reduction of labor force and improvement of construction supervision

   The visualized information can be shared not only by the measurer and the construction worker, but also by the construction supervisor. Therefore, the construction supervisor can check the accuracy in real time while anywhere at any time.

   ③Improvement of productivity

   With the conventional method, two devices and two operators are needed; however, just one device and one operator are needed with the TATEKATA KING System, and in addition, radio communication is eliminated, so as a result, work efficiency is significantly improved.
   

   • *The conventional method takes around 40 minutes to adjust the erection of eight columns. The same job can be done in just 16 minutes by using the TATEKATA KING System, an approximate time reduction of 40%.

   ④Cost reduction

   Since just one operator is required, it is expected that the cost can be reduced by about 30%.

4. 4．Further Development

   We actively engage in the leasing business of TATEKATA KING as well as provide measuring services on a contractual basis. Moreover, we will add additional functions aimed at further productivity improvement to upgrade our products.
