20, various taxes and fees paid to the state (the total cost of 3.3 ~ 3.5%): 33 ~ 70 Yuan / square meter, high-end may be as high as 100 yuan / square meter. -
not counted more than decoration, usually cost about 1000 ~ 2000 yuan / square meter, high-end residential up to 3,500 yuan. Above do not include some of the corruption caused by state-owned enterprises development costs. The decor is generally 500 to 1,500 yuan / square meter, depending on grade level, there are 300 yuan / square meter Jianzhuang Xiu, more 3,000 to 10,000 yuan / square meter ultra high-end renovation (bag check.) -
21, design fees (including fees during the initial design concept): 15 ~ 100 yuan / square meter; -

24, the land cost: general second-tier urban areas (the old rural areas) is 70 ~ 100 million / acre, floor area ratio is generally 1.0 to 2.0, so the conversion rate is: 525 ~ 1500 yuan / sq m, the urban center generally is 200 yuan / mu, conversion rates are: 1500 ~ 3000 yuan / sq m, the core region up to 300 yuan / mu, the land cost more unilateral; first-tier cities and even up to 20,000 yuan / square meter unilateral cost of the land above; third-tier cities, counties and other unilateral lower cost of land, usually 100 to 500 yuan / square meter, there are up to 2,000 yuan / square meters of the situation; -
25, land tax and pre-fee, generally about 15% of land costs, second-tier cities is generally 100 to 500 yuan / square meter, around the standard is different. -
Conclusion: The basic construction cost is fixed, even if we do not accept the relocation of the Housing section of land, construction of the national minimum standards, the cost is difficult to less than 1,000 yuan / square meter. In fact, the multi-ordinary housing, and Chien costs about 1,200 yuan / square meters, a small high-rise and high-level general commercial, and Chien cost about 1500 ~ 1800 yuan / square meters, the higher the grade, the higher the cost. Can be none other key is: the district level, the land to the government to pay part of the local government fees and taxes, advertising, sale of part of the cost of planning, renovation costs. In addition, the developer of the development of quality there is a certain relationship, If you always keep the prices down, quality is to be worse; private developers than the state / government developers indeed lower the cost, mainly two reasons, first, most of the private enterprises are mainly oriented to efficiency, cost control some better general, and second, the cost of private enterprise corruption is relatively lower. Whatever the reason, up and down with the quality of the district will not exceed the cost of 100 to 200 yuan / square meter. -
the basis of common sense
12 requires 64 square wall of a standard brick wall
18 a square requires 96 standard bricks
24 need 128 square wall of a standard brick wall of a square to be
37 to 192 standard bricks
49 wall must be a 256 a square brick
standard formula:
wall unit dosage of 240 cubic meters of 1 / (0.24 * 0.12 * 0.6 )
wall unit dosage of 370 cubic meters of 1 / (0.37 * 0.12 * 0.6)
hollow wall of a square requires 80 of 24 A multi-block standard brick
civil engineer should have the data (transfer)
an ordinary residential buildings of concrete and steel consumption volume:

7, Villa amount of concrete and steel consumption is between 11-12 high-level multi-layer masonry between residential and more data are
7 degree earthquake zone rules design
Second, ordinary multi-storey residential building construction budget economic indicators
1, outside doors and windows (not including the cell door, security door) area total building area of 0.20-0.24
2, total construction area of the template area of about 2.2
3, the outdoor area of the floor area of plaster around 0.4
4, interior plaster will occupy an area of 3.8
three buildings, the construction efficiency
1, a plaster plaster work in the 35 square meters a day
2, a red brick brickwork 1000-1800 block puzzle day
3, a brick 800-1000 hollow brick work block puzzle day
4, tile 15 square meters
5, 300 square meters of first pass scraping white / day 180 m second time / day, the third time calendar of 90 square meters / day
four basic data
1, concrete weight 2500KG/m3
; 2, the weight of steel per meter 0.00617 * d * d
3, dry sand weight 1500KG/m3, wet sand weight 1700KG/m3
4, stone weight 2200KG/m3
5, about one cubic meter of red brick 525 (min thickness of the wall)
6, one cubic meter of hollow brick 175 or so
7, screening 1.3 one side clean sand to be a little different point of view of ordinary sand
:
1, the ordinary multi-storey residential masonry: steel 25-30KG/m2, including affordable housing for the 16--18KG/m2.
2, ordinary multi-storey masonry houses, plastering the outdoor area of the floor area of 0.5 - 0.7.
3, ordinary multi-storey masonry residential area of the building area template 1.3 - 2.2, according to the number of cast panels, a large column density.
4, a brick wall brickwork 1000-1800 240 puzzle pieces a day, 370 or 500 Wall 2000 - 3000 block.
5, reinforced concrete weight 2200KG/m3, plain concrete weight 2100KG/m3.
6, project stone weight 1800KG/m3. )
0.617 is the weight per meter of reinforced round of 10. Steel weight and diameter (radius) proportional to the square.
G = 0.617 * D * D/100
weight per meter (Kg) = bar diameter (mm) × diameter steel bars (mm) × 0.00617
in fact remember the weight of steel commonly used in construction projects is also very simple
φ6 = 0.222 Kg; φ6.5 = 0.26kg; φ8 = 0.395kg; φ10 = 0.617kg; φ12 = 0.888kg; Φ14 = 1.21kg; Φ16 = 1.58kg; Φ18 = 2.0kg ; Φ24 = 2.47kg; Φ22 = 2.98kg; Φ25 = 3.85kg; Φ28 = 4.837kg 12) below and Φ28 (including 28) of the steel generally take three digits after the decimal point, Φ14 Φ25 reinforced to take two digits after the decimal point generally
Φ6 = 0.222Kg
Φ8 = 0.395Kg
Φ10 = 0.617Kg
Φ12 = 0.888Kg
Φ14 = 1.21Kg
; Φ16 = 1.58Kg
Φ18 = 2Kg
Φ20 = 2.47Kg
; Φ22 = 3Kg
Φ25 = 3.86Kg
formula I have the experience, your own Calculation of a table on it. Forms can also go to buy a book with them is also very convenient.
theoretical weight of steel material name
simplified theoretical weight W (kg / m)
; flat steel, steel sheet, strip W = 0.00785 × width × thickness
square steel W = 0.00785 × side length 2
round bar, wire rod, steel wire W = 0.00617 × diameter 2
steel wall thickness W = 0.02466 × (OD - Wall Thickness)
; other side edge angle W = 0.00785 × thickness (2 edge width - edge thickness)
unequal angle W = 0.00785 × edge thickness (L short side edge width + width - edge thickness)
beam waist W = 0.00785 × thickness [high + f (leg width - waist thick)]
channel W = 0.00785 × waist thick [high + e (leg width - waist thick)]
Notes
1 , angle steel, channel steel I-beam and the exact formula is complex, and the table used to calculate the approximate simplified.
2, f values: general models and with a, 3.34, 2.65 with b, with c, was 2.26.
3, e values: general models and with a, 3.26, 2.44 with b, with c, 2.24.
4, the length of the units are in millimeters
