What is the installation price of fire water and electricity?

General residential building installation labor price in 30 yuan/square. The commercial part is excluded, because there are many things involved in business, such as spraying and fire fighting linkage. General business can be built in 50 yuan/square. As for the price of contract and materials, residential buildings can be built between 140 and 150. Of course, it is not a resettlement house, and there are fewer resettlement houses. It is really impossible for the commercial part to quote like this. If this is the case, it is likely to be a loss, and it should be calculated according to the drawings. However, there should not be many things in the commercial building. The key is that he finished it once and renovated it twice, which depends on reality.
