Cost analysis of underground mechanical parking system: Mechanical parking increases the cost.
Manufacturer's quotation: the manufacturers in different places are basically the same, and the basic quotation is 20,000 yuan/parking space.
(Consulting manufacturer: Shandong * * *, Beijing * *) After many consultations,
The lowest possible quotation is as follows: price composition: 1, equipment price: 15000 yuan/parking space. 2. Maintenance fee: 200 yuan/year 3. Electricity charge: 1 yuan/time.
According to the manufacturer, the most economical underground parking mode for vehicles is: 6-parking module, 1, equipment price 17500 yuan/parking space. Analysis: (two-story lifting and traversing) underground mechanical parking scheme
According to the most convenient 6-car parking module (maintenance and use fees are not considered, because these fees can be collected in the process of property management): Features:
This parking mode has a clear distance between walls of 7500mm and an actual column grid span of 8000mm, which basically meets the requirements of basement economic span and is relatively economical. So we use the 6- parking module as the calculation basis. Its placement schematic diagram is as follows:
1, 2 can pick up the car directly, 3, 4, 5 can pick up the car directly if it happens to be in the lower floor, otherwise it needs to be operated, and the system will automatically judge and choose the lifting and traversing mode to move to the lower floor. The price of a single parking space is 6 parking spaces: 8000 mm column? The calculated unit price of modular parking space is * * *: 15000x6 = 90000 yuan.
Because three cars can be parked in the same parking space without mechanical parking, now mechanical parking is used, and because one parking space must be reserved for vehicle translation and lifting, two parking spaces are actually added: the cost of adding a single parking space is 90,000 yuan/(6/2-1) = 45,000 yuan/parking space.
That is, under the condition that the original number of parking spaces in the basement remains unchanged, the cost of adding a parking space equipment is 45,000 yuan. Parking space size: Based on the floor area occupied by a parking space on the first floor: 35m2/parking space, the newly added parking space is equivalent to 35x3/2 = 52.5m2/parking space.
Theoretical value: construction area plus parking cost is 45,000/52.5 = 857,438+04 yuan/square meter.
Calculation standard of increased cost of civil engineering:
According to the data provided by consulting Metropark Architectural Design Office:
The single-story basement is 3800 mm high (refer to the basement data of Hefei Yijingyuan).
Equipment clearance requirements: 3650 mm beam, plate height and equipment pipeline spacing 1750 mm total 5400 mm height increase: 5400-3800= 1600 mm related increase costs:
The column section is increased from 500X500 to 600X600. Net area of column: 8 X 8 = 64 square meters
Increase column concrete quantity: 0.36x5.4-0.25x3.8 = 0.994m3.
The converted cost is 0.994x1700x1.5/64 = 39.60 yuan /m2, and 40 yuan /m2 (1700 is the single column cost; 1.5 is the coefficient of column folding area) Retaining wall 300 is increased to 350? 40 yuan /m2 is equivalent to the column parameter.
The anti-floating thickness of bottom plate is increased 100?
The reduced cost is 0.1x1200 =120 yuan /m2, and the anti-floating of the pile is increased by 3000mm.
Increase pile concrete quantity: 0.36x3 =1.08m3.
The converted cost is1.08x1800x1.5/64 = 45.56 yuan /m2, and 46 yuan /m2 (1800 is the cost of a single pile; 1.5 is the column folding area coefficient. ) Waterproofing of external wall of wall is increased:?
50 yuan/square meter x conversion coefficient 0. 1 X height conversion coefficient 0.5 =2.5 yuan/square meter, 3 yuan/square meter, total civil works: 40+40+ 120+46+3 = 249 yuan/square meter.
Considering the increase in the cost of digging, civil air defense, plastering and painting, the comprehensive cost is increased by 5 1 yuan/square meter: 255+45=300 yuan/square meter.
Therefore, when the building cost is 1600 storeys high, the installation cost of 300 yuan /m2 will be increased, and the comprehensive cost of 50 yuan /m2 will be increased.
Total increase cost of construction project 350 yuan /m2 (excluding construction measures such as basement dewatering and slope protection) Total increase cost.
According to the theoretical value of six parking spaces: parking space cost: 857. 14 yuan/m2; The height of basement is increased: 350 yuan/m2.
Total: 2100+857.14+350 = 3307.14 yuan/m2.
Analysis: underground mechanical parking scheme (three-story lifting and transverse pit type)
Calculated according to the most convenient 9-car parking module (maintenance and use fees are not considered, because these fees can be collected in the process of property management): Features:
This parking mode has a clear distance between walls of 7500mm and an actual column grid span of 8000mm, which basically meets the requirements of basement economic span and is relatively economical. Therefore, we take 9 parking modules as the calculation basis. Its placement schematic diagram is as follows:
The system can automatically judge and select the fastest moving mode. If the parking space is as shown in the above figure, the moving modes are: 4, 5, direct access to the car, 2, access to the car after descending, and 7, access to the car after ascending.
1 3 When getting into or out of the car, first move 4 or 5 horizontally, and then lower the parking space; When entering or leaving the car on 6 or 8, move 4 or 5 horizontally before raising the parking space. The price of a single parking space is 9 parking spaces: the column is 8000 mm? The calculated unit price of modular parking space is * * *:17500x9 =157500 yuan.
Because three cars can be parked in the same parking space without mechanical parking, now mechanical parking is adopted, and one parking space must be reserved for vehicle translation and lifting, so five parking spaces are actually added: the cost of a single parking space is157500/(9-3-1) = 31500 yuan/parking space.
That is, the cost of adding a parking space is 3 1.500 yuan under the condition that the original number of parking spaces in the basement remains unchanged. Parking space size: Based on the floor area occupied by a parking space on the first floor: 35 m2/parking space, the newly added parking space is equivalent to 35 x 3/5 = 2 1 m2/parking space.
Theoretical value: construction area plus parking cost: 31.500/21=1.500 yuan /m2. Calculation standard of civil engineering increase cost:
The single-story basement is 3800 mm high (refer to the basement data of Hefei Yijingyuan).

Height increase: 7400-3800= 3600 mm Related increase cost:
The cross section of the column is increased from 500X500 to 600X600, and the net area of the column is 8×8 = 64 square meters.
Increase the amount of column concrete: 0.36x7.4-0.25x3.8 =1.714m3.
The converted cost is1.714x 1700x1.5/64 = 68.29 yuan/m2, and 70 yuan/m2 (1700 is the single column cost; 1.5 is the coefficient of column folding area) Retaining wall 300 is increased to 400? 70 yuan /m2 is equivalent to column parameters? The anti-floating thickness of the bottom plate is increased by 200.
The converted cost is 0.2X 1200=240 yuan /m2 and 240 yuan /m2 (1200 is the cost of single board)? The anti-floating of piles is increased by 6000mm.
Increase pile concrete quantity: 0.36×6 = 2. 16 m3.
The converted cost is 2.16x1800x1.5/64 = 91.125 yuan /m2, and 95 yuan /m2 (1800 is the single pile cost; 1.5 is the column folding area coefficient. ) Waterproofing of external wall of wall is increased:?
50 yuan/square meter x conversion coefficient 0. 1 X height conversion coefficient 1 =5 yuan/square meter, 5 yuan/square meter, total civil works: 40+40+ 120+52+5 = 255 yuan/square meter? Increase of beam slab of the bottom elevated driveway: increase of concrete quantity: 0.4 m.
The converted cost is 0.4X 1200 X 20/35 =274 yuan/m2, and 275 yuan/m2 (1200 is the cost of single beam slab; 20/35 is the area coefficient of overhead folding building) The pit side wall is enlarged:? Increase the amount of wall concrete: 0.25m.
The converted cost is 0.25x1200x15/35 =128.57 yuan /m2, 130 yuan /m2 (1200 is the single wall cost; 15/35 refers to the construction area coefficient of the overhead side wall pit)
Total civil works: 70+70+240+95+255+275+130 =1135 yuan /m2.
Considering the increase in the cost of digging, civil air defense and painting, the comprehensive civil construction cost of 65 yuan /m2 is increased:1135+65 = 1200 yuan /m2, so the civil construction cost is increased1200 yuan /m2, and the installation cost is increased by 80 yuan /m2.
The total increased cost of the construction project is 1280 yuan /m2 (excluding the cost of construction measures such as basement dewatering and slope protection).
According to the theoretical value of 9 parking spaces: parking space cost: 1500 yuan/square meter; The height of the basement is increased: 1280 yuan/m2.
