The sixth district of Beijing invested in a new five-star hotel with a height of less than 100m, 25 floors and a construction area of 50000m2. What is the investment cost per square meter of fire fighting project? The detector is about 100 yuan (between 35 and 400 yuan) × 4000 = 400,000 yuan; Hidden nozzle 15 yuan (10-35 yuan) ×6000 (about) = 90,000 yuan; Fire hydrant 4000 yuan (2000-6000 yuan) ×800 sets = 3.2 million yuan; Infrared pursuit automatic water cannon 30,000 yuan (6,543.8+0,000 yuan-6,543.8+0,000 yuan) ×2 seats (about) = 60,000 yuan; The heptafluoropropane gas fire extinguishing system is 654.38+00,000 yuan× 4 (about) = 40,000 yuan; Cable TV is about 200,000; Steel (bracket, etc. ) 654.38+ ten thousand yuan; Emergency light 30 yuan (20-50 yuan) ×500 (about) = 6.5438+0.5 million yuan; 30 yuan (20-50 yuan) ×500 evacuation signs (about) = 6,543,800 yuan; Fire alarm control system (including ventilation system) is 6,543,800 yuan. The material cost is estimated to be 5 1.2 million yuan. The labor cost is usually 15-25% of the material cost, and 5 12×20% = 1024000 yuan (about). The total cost is about 6 1.44 million yuan. 6 144000 yuan ÷ 50000m2 =122.88 yuan (cost per square meter). This price is only a rough reference. There will be other expenses, such as taxes and fees, qualification management fees of affiliated companies, and other materials fees, which are not included. After all, the information you gave is limited and you can only estimate it, but the total cost should not exceed 8 million.
