The cost of hydropower reform is higher than that of the decoration company, mostly because at the beginning of the quotation, the decoration company will say that the actual cost of hydropower reform is based on the actual amount. The quotation is only a rough estimate. It is for the decoration company to let the decoration owner choose them. Most of the pressure will be very low. The reason why the hydropower reform project cannot be included in the fixed contract is that the designers of the decoration company are very good at designing the appearance and function of the living room, but often lack expertise in water and electricity, and also the company’s technical standards for hydropower construction. Lack of understanding; designers from the drawing point of view, a straight line between two points on it, but in the construction process, to consider many situations, such as the structure of the wall, sometimes it must be winding, winding The costs incurred by the line will inevitably be higher than the straight line connection, and the amount will be less, and the actual construction cost will naturally be much higher than the designer's estimated cost. And the actual environment of the living room is more complicated. These cannot be reflected in the plan. Taking the pipeline needs to adapt to the situation on the ground. That is to say, the actual number of pipelines can not be determined by the plane paper, but it is necessary to go to the site to release the line. Measurements can only be made clear. Therefore, the hydropower project cannot write accurate construction quantities in the contract. In this regard, experts suggest that home improvement owners should pay attention to the following aspects when carrying out hydropower reforms at home: 1. Before the construction of new houses and hydropower, consumers can do the insulation test on the original wires first. If there is no problem with the test and the wire diameter meets the requirements, they can be replaced without replacement. Consumers should not rely on the words of some decoration company constructors that “all developers use poor quality electric wires and are prone to electric leakage†and still have to make their own judgments. 2. During the construction of hydropower reform, consumers should pay attention to observing whether the hydropower pipelines of the construction team follow the shortest distance. It is advisable to consult the national relevant hydropower project construction standards in advance. Before signing the contract, pay attention to the decoration company on hydropower. Some specifications of the construction are conducive to effective supervision of the construction team. 3. Investigators who seek knowledge during construction should supervise their hydropower renovation projects to avoid problems.
