| Piling is noisy and can damage buildings Sheet piling, bulldozing and excavation have substantial impact on the environment. Installing piling for building stability creates sound at decibel levels that are unacceptable in most cases. Hammering down concrete piles with a five ton driver is very noticeable to everyone in the vicinity. If the piling job lasts for a month or more, it will mean significant problems. Vibration and noise are perhaps the most apparent disturbances from construction work. But there is also the substantial risk of movement in buildings adjacent to sensitive walls. Vibrations and frame sounds can be tangible in residential buildings as well. Vibration and movement increases the risk of subsidence, which also can result in unwanted economic consequences. Poor measurements can be misinterpreted and equal “rubbish” Construction companies and entrepreneurs are seldom willing to pay for monitored sound measurements over a period of several days. Instead, and because of cost aspects, unmanned sound measurements are carried out. But such stinginess can cause interpretation difficulties concerning, “what noise has appeared during and after the measurement period". With INFRA, unattended measurements are not only equally as good as manned measurements but also provide a high quality result which is objection free. One INFRA measurement setup can concurrently measure both static and dynamic effects. Data regarding vibration, noise, crevice movements and inclination changes can be promptly presented in one report.
