Compare the vibration levels of areas without countermeasures and areas with WIB countermeasures! Confirmed a reduction of 6dB or more in both horizontal and vertical directions.
At Daiho Construction in Fukushima Prefecture, there were concerns about the impact of construction vibrations from the government office building on surrounding residences. In response, the "WIB method" was implemented around the government office building. After the measures were taken, vibration measurements were conducted to investigate the impact of construction work on the surrounding area. A comparison of vibration levels between untreated areas and those treated with the WIB method showed a reduction of over 6dB in both horizontal and vertical directions. The vibrations were halved. 【Case Summary】 ■ Location: Fukushima Prefecture ■ Client: Daiho Construction Co., Ltd. ■ Vibration Source: Construction work vibrations ■ Preservation Target: Residences around the government office building ■ Countermeasure: Wall-type WIB method (folding screen type) ■ Installation Position: Vibration propagation path *For more details, please refer to the PDF document or feel free to contact us.
