During each building, there should be planned deployment of various types of installation, without which the house would not work in such a way, as it should. The first installation is performed on the first stage of the work, that is precisely the creation of foundations. These include inter alia, sewer pipes, water supply and power cables. Additional installations are mounted at the wall. There you will also find the water pipes or the water supply. Then you can proceed to mount electrical installation. If you wish to have a floor heating, then after mounted the electrical installation you can take care of the localization of pipes for this kind of heat.
