Decoration cost calculation 1. Labor, materials and machinery consumption (the main indicators in the budget quota)
Fixed labor cost = fixed working days * daily wage standard
Quota material fee = material quantity * material budget price+loss fee+transportation fee+equipment fee+management fee+tax.
Due to the different prices of materials in different places, the decoration cost is different, but the calculation formula of decoration engineering quantity is the same. When decorating, you can calculate the material consumption according to the calculation formula in the following example.
Calculation of decoration cost. Amount of floor tiles: (Note: Generally, the loss rate of different rooms is about 1-5%)
Dosage per 100 m = 100/ (block length+mortar joint width) * (block width+mortar joint width) *( 1+ loss rate)
Example: The size of the selected retro brick is 0.5*0.5M, the flat-fell seam width is 0.002M, the loss rate is 1%, and the number of blocks required for 100 m2 is: 100 m2 consumption =100/(0.5+0.002).
Total price = number of tiles * unit price of tiles
Decoration cost calculation. Maximum consumption
Ceiling consumption = (length-shielding length) * (width-shielding width)
For example, the amount of plastic ceiling calculated by net inch area, the unit price of PVC plastic board is 50.8 1 yuan /m2, the shielding length and width is 0.24M, the ceiling length is 3M, and the width is 4.5M.
The dosage of ceiling board = (3-0.24) * (4.5-0.24) is approximately equal to 1 1.76/ m2.
Decoration cost calculation. Door consumption
Number of door covering materials = door frame length * door frame width
For example, the door is covered with wooden boards, the outer frame of the door is 2.7M long and 1.5M wide, and the material consumption is as follows.
Amount of door covering material = 2.7 *1.5 = 4.05m2.
Decoration cost calculation. dosage
Usage of wallpaper = (height-shielding length) * (width-shielding width) * number of walls-door area-window area
For example, if the wall surface is calculated according to the net size area, the shielding is 24CM, the wall height is 2.5M, the width is 5M, the door area is 2.8 square meters, and the window area is 3.6 square meters, then the dosage is as follows:
The amount of wallpaper = (2.5-0.24 * (5-0.24)) * 4-2.8-3.6 is about 36.6 square meters.
Decoration cost calculation. Consumption (solid wood)
Longitudinal dosage = room length/floor tile length
Horizontal dosage = room width/floor tile width
In case of unreasonable division, rounding method should be adopted, but in the vertical direction, less than half a block is counted as half a block, and more than half a block is counted as one.
Total floor price = total consumption * unit price
Floor loss = floor area-house area
Floor loss rate = floor loss/housing area
Note: The general floor loss rate does not exceed 5%.
Decoration cost calculation. The amount of wall materials.
After determining the design and variety of the wall-sticking material, the material size can be reasonably calculated according to the size of the living room. Considering the possible loss in the construction process, you can buy about 5% more than the actual consumption. There are two methods to calculate the wall-attached material.
Calculated by the formula, the area of the room is multiplied by 2.5, and the product is the number of materials attached to the wall. For example, the material of a 20-square-meter room is 20*2.5=50m, and there is a more accurate formula:
S=(L/M+ 1)(H+h)+C/M
Where s refers to the length (m) of the required wall adhesive material.
L—— Total length of four walls after deducting equidistant lines (m)
M—— the width (m) of the wall-sticking material plus 1 as the allowance of the mosaic pattern.
H—— the height (m) of the required wall sticking material.
H—— the distance (m) between two identical patterns on the wall sticking material.
C—— the area (square meters) where the doors and windows are pasted up and down.
Field measurement shows that this method has high accuracy. First, we need to know the width of the material to be pasted on the wall, and then measure the perimeter of the room wall (excluding doors and windows) in turn. There are several widths of the material to be pasted on the wall in the perimeter, that is, we need to paste several pieces, and then measure the height of the material to be pasted on the wall, multiplied by the number of pieces, which is the length (m) of the material to be pasted on the wall outside the doors and windows. Finally, this method is still used to measure the length of the required material under the window, irregular corners and so on. , and add it to the calculated length, which is the total length. This method is more suitable for subdivided patterns, and there is no need for specially aligned wall materials when splicing.
Calculation of decoration cost. Estimation method of consumption
Introduce a simple calculation method:
Room area (square meters) divided by 4. The height (decimeter) of the wall to be painted is divided by 4, and the sum of the two figures is the number of kilograms to be painted.
For example, a room with an area of 20 square meters and a wall height of 16 decimeter (excluding the dado of 12 decimeter) is (20÷4)+( 16÷4)=9, that is, 9 kilograms of paint can be used to paint the wall twice.
The above is the introduction of the decoration cost calculation we brought to you, hoping to bring you some help. I wonder if you are satisfied with the introduction of Bian Xiao?
