(I) Several major factors affecting the decoration cost 1. The number of decoration items and quantities of work is a direct factor that affects the cost. Before decorating, you should first determine the content of the decoration (such as how many cabinets to use, whether to use paint or wallpaper, what kind of top should be lifted, what sanitary ware to choose, what kind of floor to spread, etc.), and then accurately calculate the amount of work based on the content. Contains labor and materials). 2. Difficulty and ease of decoration and precision requirements are the main factors affecting the cost. For example, it is a pipeline. It is cheaper to take the open line and it is more expensive to go to the dark line. Ordinary ceilings are cheaper, but more complex ceilings with high and low levels will be more expensive; the same floor, solid wood flooring and composite floor labor costs are not the same; In addition, the installation costs of different grades of sanitary ware will also be different. The installation of 3,000 yuan is not the same as 30,000 yuan. 3. Decoration grade is the key to affecting the cost. The same materials or equipment, the original imported products, joint venture products and domestic products in the price difference. If the same is a sanitary ware, domestically produced about 1 to 3,000 yuan, and joint ventures, generally about 5 to 8,000 yuan, then it is imported at least 10,000 yuan, and some even more than 30,000 yuan. For the average person, the selection is very particular. The important principle is that key parts should use some high-grade materials as their own economic capabilities, while other parts can use some common materials, so that the cost will drop. For example, when using latex paint, the wall paint can use high-grade elastic paint, while the top surface can use ordinary matte paint. 4. Market price fluctuations are also a factor. To keep abreast of the market conditions, when purchasing more than a "comparison of three" in quality and price, of course, it is best to find manufacturers of direct sales units or agents. In the process of contracting materials, it is also necessary to understand the market conditions and the amount of materials in order to avoid being “defectiveâ€. 5. The level of the construction unit is different, and the charging standards are also different - the higher the level, the more expensive the price. Apart from the construction quality, the scale of the decoration company alone is large, the office location is good, the site is large, and the administrative expenses incurred are also large. (B) determine the decorative items and decorative standards The decoration items and decoration standards should be comprehensively considered according to the conditions of the housing and the family's economic situation. They should not copy people's appearances (this will lose their own style), and they should not blindly compare them, because the level of decoration and requirements are not enough The same, the price will be very different. For example, take the average resident's mid-range decoration standard as an example (the type of house is as follows: two-bedroom, one-bedroom, one-bathroom and double-balcony residential house): toilets, kitchen floor tiles, and ceramic tiles; the top of the bathroom is made of PVC plastic gussets. Ceiling; Imitation porcelain paint for kitchen ceilings; Semi-gloss paint for indoor walls; Matt paint for ceilings; Living room (restaurant) made of one-meter-high wooden wall skirts, floor walkways covered in bricks; Cover, wood hanging mirror line or wood decoration line, long wooden curtain box, double wrap wooden door cover; Inner window plus aluminum alloy sliding window, balcony sealing aluminum alloy window, changing aluminum alloy door and window; Lighting ceiling with ring art lamp , change the cable switch, etc. The cost of such decoration projects and decoration standards is calculated at the current Shanghai market price of 20,000 yuan. Kitchen equipment, kitchen utensils update: use fire board to make cupboards, hanging cupboards, use marble or stainless steel to make countertops, use stainless steel wash basins and faucets, cabinet-type deep range hoods, gas stoves and water heaters, electrical switches, sockets, wiring, The lighting transformation, etc., is estimated to be 8,000 yuan more according to the current market price in Shanghai. Renovation of bathroom equipment: selection of medium-to-high-grade sanitary ware produced by Sino-foreign joint ventures, washbasins and marble countertops, commodes, bathtubs, soap jars, paper cylinders, stainless steel nozzles, faucets, towel rails, shower curtain rods and curtains, large mirrors or mirrors Boxes, wall lamps, exhaust fans, etc., are estimated to be 7,000 yuan more according to the current Shanghai market price. The above three items total about 35,000 yuan (excluding furniture and household appliances). (three) to master the method of cost estimation There are generally two ways to estimate home decoration costs: 1. Direct cost + (direct cost X comprehensive coefficient) = total cost The direct cost includes: materials, equipment accessories, freight and labor costs. The freight rate in the city is generally 1.5%, and the labor cost is generally 30 to 50 yuan for 1 working day. The comprehensive coefficient includes: profit, various construction charges, taxation fees, generally about 20%. The tax is about 3.8%, and the management fee is about 7-10%. If the direct cost is 20,000 yuan and the overall coefficient is 20%, the total cost = 20,000 + (20,000X20%) = 24,000 yuan. The above calculation methods belong to the "transparent quotation" commonly used by large companies, that is, the unit price of each material does not exceed the market guidance price. This is very important for those who demand high-end decoration. If the total cost of decorating 500,000 yuan, a difference of 1,2 percentage points is a spread of 10,000 yuan. However, the general decoration company adopts a relatively simple method, that is, the total cost = material fee + labor fee, therefore, in practice, it must be flexible and carefully calculated, and must not be applied mechanically. 2. The total sum of the cost of the single project contracting and the total cost = the total cost If the cost of artificial materials for latex paint is 15 yuan per square meter and the area to be painted is 150 square meters, the single project price for the wall project will be equal to 2,250 yuan, and the individual cost of each project will be calculated one by one. And then sum, the sum is the total cost. The total construction cost already includes clear construction waste and freight, and should not be double counted. If the user supplies materials or equipment by himself, the corresponding materials or equipment shall be deducted. Estimated cost of home decoration, the general use of package materials more methods, special decoration prices are negotiable. After the price has been negotiated by both parties, it is possible to sign a decoration contract. In the contract, it is necessary to indicate that the total cost will be packaged once. If there is a change, another increase or decrease will be made. The terms of the construction period, quality, payment method, and warranty period should also be stated in the contract. The contract will be effective immediately upon signature and stamping of the parties. At this time, it is necessary to pre-pay approximately 30-50% of the total cost of the project, and the balance can be paid in installments according to the specific circumstances, or it can be paid once after the final acceptance.
