>>>>Teach you to read the decoration company quote
The budgetary quota for home interior decoration projects is an important part of home decoration. It is directly related to the economy's ability with the economy and the rational distribution of the economy. Generally speaking, the project budget quota is the standard and basis for settlement quotas in the later stages of the project. The difference between them is only between 3% and 5%. Therefore, the project budget occupies an important position in the interior decoration.
The budget for the interior decoration project is based on:
1, decoration engineering design. Including planning maps, that is, the plane sketches before the interior decoration and the plane sketches in the decoration; the local maps, such as the kitchen, living room, and bedroom in the room.
2, decorative effect map. Including the overall renderings, that is, the rendering of the entire room; local renderings, that is, renderings of each unit in the room.
3, decoration engineering construction program.
Interior decoration preparation methods and steps:
1. Collect data. Collect the information needed to prepare the budget, and find out where the required materials are located and the transportation routes in order to determine the required removal fee.
2, familiar with the contents of the drawings, master the design intent. The construction drawing is the main basis for calculating the engineering quantity and applying the budget quota. Therefore, the following contents must be carefully read: the elevation and section size of the wall cylinder, the decoration materials and practices, and the connection treatment between the decoration part and its components; the skeleton of the ceiling, the structure of the panel The types and materials of doors and windows; paints, coatings, pastes and other parts and requirements; interior decoration, lamps, mirrors, cabinets and other items size and practice requirements.
3, read the quota instructions, calculate the amount of work. On the basis of reading the drawings, first read the general description of the quota, and then read the description of the segment and the calculation rules of the quantity of the project in accordance with the relevant contents of the drawings in accordance with the arrangement order of the quota.
4. Apply the quota or unit valuation table to calculate the direct fee. Calculate the project quantity, according to the unit of measurement required by the quota item number, and multiply the labor fee, material fee, and mechanical fee in the quota one by one, and the total sum is the direct fee of the project. The specific calculations are made on the budget table.
The consumption of labor, materials, and machinery in the decoration budget is the main indicator in the budget quota, and its formula is as follows:
Fixed labor costs = fixed number of working days × daily wage standard fixed material costs = material quantity × material budget price + mechanical consumption (machine consumption is 1% - 2% of material costs)
In the actual decoration, the decoration budget cost = material fee + labor fee + loss fee + transportation fee + machine tool fee + management fee + tax. Due to the different materials prices in different regions, the decoration costs are not the same, but the calculation formula for the amount of decoration works is the same. During the decoration, the amount of materials can be calculated according to the calculation formula in the following example.
Floor tile usage:
The amount per hundred meters = 100 ÷ [(block length + mortar width) × (block width + mortar width)] × (1 + loss rate)
For example, the size of the retro floor tile is 0.5×0.5M, the seam width is 0.002M, the loss rate is 1%, and the required number of blocks is 100 square meters : 100 square meters usage=100÷[(0.5+0.002)×(0.5+ 0.002) × (1+0.01) = 401 ceiling usage:
Roof plate usage=(length-shield length)×(width-shield width)
For example, the amount of PVC plastic ceiling can be calculated from the net size area. The unit price of the PVC plastic plate is 50.81 yuan/M2, the length and width of the shielding are both 0.24M, the length of the ceiling is 3M, and the width is 4.5M. The dosage is as follows:
The amount of ceiling plate = (3-.0.24) × (4.5-0.24) = 11.76 M2
Package door dosage:
Package door material usage = door outer frame length × door frame width, for example (as shown in the figure) with composite wood package door, door outer frame length 2.7M, width 1.5M, then its material usage is as follows:
Package door material amount =2.7×1.5=4.05M2
Wallpaper usage:
Wallpaper Usage = (High - Shielded Length) × (Width - Shielded Width) × Number of Walls - Door Area - Window Area (For example) Wall Area is calculated as net size, shield is 24CM, wall height is 2.5M, width is 5M, The door area is 2.8M2 and the window area is 3.6M2. The dosage is as follows:
Wallpaper Usage = [(2.5-0.24) × (5-0.24)] × 4-2.8-3.6 = 36.6 M2
The above is the calculation of some of the amount of materials used, so that each part of the amount of decoration materials multiplied by their respective unit price accumulated, the total cost of materials for the decoration project.
It should be noted that housing renovation according to the project investment limits and construction materials standards are different, the budget cost spread is very large, so in the decoration should be carefully analyzed from the scientific and artistic point of view, select the right material, and make it a reasonable match, come Do a good job of budgeting in advance.
