In most cases, when huge objects are built, with such a large number of building materials, a solid building company has a certificate that they meet the established requirements. When people receive a certificate, accordingly, the manufacturer of materials provides the highest quality material. If you have a large enough object, then in this case it is best to conduct an independent examination, that is, go to the house and take air sample, as well as send building materials for examination to the laboratory. And see if they correspond to their declared characteristics. Experts are already going to the place and assess the territory itself directly. If all grades pass positively, then they are already moving to the examination itself. Soil samples, water are taken, the noise level in the territory and electromagnetic radiation is estimated if there are some other objects nearby. A certificate and conclusion on all studies are issued. There are standards that regulate the release of harmful substances into the air, and there are special requirements for building materials that they should not allocate harmful substances. These are the so -called sanitary norms. If it turns out that some materials do not comply with sanitary standards, then in this case it is necessary to contact a lawyer and begin office work.
