[To the construction DX promotion personnel of the main contractor] An introduction to "Key Points for Choosing an App for Successful Implementation" from the perspective of a construction management app provider used by 100,000 companies.

We will introduce selection points to find "the one that fits your company" among many options. "Collection of successful implementation case studies - available now."

Compared to a few years ago, the term "Construction DX" has permeated the entire industry, and many construction management apps and systems have emerged. For those wondering, "How should I choose among the various apps and systems that look similar?" we present the "Key Points for Selecting Construction Management Apps"! ■ Three Checkpoints for Successfully Implementing Construction Management Apps 1) Confirm how the construction management app can be utilized to address your company's specific challenges. → For example, if you want to "be able to understand the situation without going to the site," it is recommended to clarify your ideal image and then research the features and strengths of each app. 2) Check if it is user-friendly for partner companies and craftsmen. → This is often overlooked! We have supported the implementation for various companies, but we have never seen a successful implementation without the cooperation of the "partner companies working on-site." 3) Confirm the follow-up support system after implementation. → Be sure to check for the presence and quality of support. Even if the tool is good, if it is used incorrectly, you may find that time passes without realizing its effectiveness... This is also a possibility.

The seismic sensor device "HK-2" detects strong tremors equivalent to a seismic intensity of 5 or higher, transmits a signal to the control room, and emergency stops the facility equipment. 【Installation Location】 Automotive parts factory 【Challenges】 Due to the maintenance and replacement of the factory equipment control devices, we considered updating the existing seismic sensors as well, but since production had already ended, we were looking for alternatives. 【Effects After Installation】 The HK-2 has the function to emergency stop equipment during an earthquake, and since its functionality is the same as the existing device, it was introduced as a replacement. Its compact size also allowed it to fit within the existing control panel being used. ★See more examples of the seismic sensor device "HK-2" https://www.hotron.co.jp/recommend/HK-2_lp.html#anchor_a04 ◎For more details, please download the materials or contact us.
