First of all, if the contractor provides the decoration service, the price of the raw materials used in the decoration project will not be used as the turnover. Construction contractor price template: 19-23 yuan / square meter (viscous ash surface); Handan: 38-41 yuan / leg; Reinforcement: 310-420 yuan / ton, or 10-13 yuan / m2; Laying: 55- 70 yuan / leg; Plastering: 7-15 yuan / square meter (not deduct the door and window openings, does not include scaffolding demolished); tile paste 18/m2; indoor floor tiles (600 * 600) 15 yuan / square meter; baseboard: 3 yuan/meter; indoor wall tiles: 25 yuan/square meter (including chamfers); stairway stone: 28 yuan/square meter; tread board edge: 10 yuan/meter.
Second, according to the square calculation, contractors need to look at specific projects: ordinary high-level, high-level, commercial office buildings, or factories. The amount of hydropower installation works in different projects is different. In fact, it is still based on the amount of workload measured. Multi-storey residential installation cost 73.47 yuan / square meter: 1. Electrical engineering 39.95 yuan / square meter 2. Intelligent project 15.87 yuan / square meter 3. Water supply and drainage project 21.6 yuan / square meter.
Third, the hydropower renovation project is a key renovation project, and this selection must be very professional. The clean-up water and electricity labor cost is about 35 yuan per metre. If material is added, the price is between 70 yuan and 85 yuan per metre. The price of hydropower reform varies greatly depending on the area. 80 square meters will cost 5,000 yuan to 6,000 yuan. If it is 120 square meters, it will cost 8,000 yuan to 9,000 yuan. The cost of hydropower projects will account for 18% of the total renovation cost. 20%.
How about the price of water and electricity contractors? Through this article, Xiaobian has already introduced it to everyone, hoping to help everyone when they choose. It is easy for the owners to find the largest initiative for the owners of clean water and energy, and all things are under their own supervision and control.
