The renovation of tens of thousands of yuan is a big event for every family . How should the home improvement be installed? How much does it cost? Of course, home improvement is based on the principle of suitable for living. The more you save, the better. Engaged in years of home improvement supervising the work of the experts told reporters, decorative items and quantities of the number of direct factors that affect the cost of building materials, technology and other is the key to cost impact, in addition, decoration company's qualifications, scale, management and other fees have also been different. Therefore, before the renovation must first go to the market to explore the field, after a detailed understanding of the various building materials, labor costs and other prices, you can roughly do a decoration budget, so that there is preparedness and battle. Typical Cases Budgeting is still overspending Ms. Xiao is a secondary homeowner and still has considerable experience in decoration. In doing budgets, large and small, to take her to do a very detailed, comprehensive, and strive to every little item is not missed, and every budget are playing a certain percentage of the cost overruns space, self-confidence "should only low cost It will not be high, but it will be overspending when it is loaded. The most unsuccessful experience was that when they bought ceramic tiles , they were catching up with the market. Because they were looking for cheap products, they chose ultra-low- quality products that were not as hard as quality . They eventually had to re-purchase new tiles and rework them. In addition to wasting materials, they also wasted more. More money and transportation. The insulation of the balcony , the equalization of the ground to find some of the additional money is really out of the original ... ... so unknowingly, farther away from the budget figures. Experience: The money spent must not be saved, so as not to regret, but also not to save too much money, if you buy a poor quality material, may affect the construction , resulting in rework, the money spent more, but also delayed the construction period, wasted time. Budget Details Accurate understanding of the indoor area can generally be negotiated with the decoration company in two ways: The decoration company provides the total decoration price according to the customer, helps the design and budget; the customer requests the decoration, the decoration company proposes the price, and then the customer approves. The first thing to do is to determine the exact size of the room and make the drawings because the prices are based on the specific dimensions, materials, and processes in the drawings. The requirements for living and use of each room are calibrated on the drawings, and a list of renovation items is listed. Then the market price is estimated based on the surveyed prices, and finally the decoration budget is obtained. The specific materials and processes must expressly understand what materials and crafts constitute the decoration company's quotation. Such as the quoted price of "wall paint 30 yuan / square meter", it is prone to disputes, because there are many series of wall paint products, the price of each paint are different, the proportion of latex paint water also has a difference. In addition, the specific process should also be clearly written, for example, the oil industry's general theory of "one end and ten sides" has many ambiguities. If "one end" refers to the primer rather than putty, the price of materials and workers will be expensive. some. If the wood base is not firmly treated, all of them become nail connections and the price will be different. Understanding different measurement methods Custom furniture , all decoration companies have differences, such as to do wooden cabinets, some companies use "Yanmi" as a unit, and some use "square meters", to understand the price when looking at the unit price calculation There is a difference in the price of the package door, and the price of the single-sided bag and the double-sided bag is different. It is also necessary to understand whether the calculation method of the wall paint is calculated in square meters and the calculation method of raw material price + construction fee is consistent. It is clear whether the floor cost includes Baseboard, buckles, installation fees and other items. For items that are missing due to unclear measurement methods, it is inevitable that on-site construction will require additional formalities, which will affect the budget and increase expenses. Basic budget two methods to estimate the cost of home improvement 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 usually 30 yuan to 50 yuan per worker 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%. For example: The direct cost is 50,000 yuan, the overall coefficient is 20%, then the total cost = 50000 +? Point 50000X20%? Snow = 60000 yuan. Explanation: The above calculation method belongs to the "transparent quotation" method commonly used by large companies, ie, the unit price of each material does not exceed the market guide price. For example, the total cost of decoration of 500,000 yuan, a difference of 1-2 percentage points is the spread of 10,000 yuan. However, the general decoration company adopts a relatively simple method, namely: total cost = material fee + labor fee. The total sum of the individual project costs plus the total sum of all material costs = total cost If the material cost of the paint plus labor costs is 15 yuan per square meter, the area to be painted is 200 square meters, and the single project price of the wall project is equal to 3,000 yuan. If the total floor price required is 4,000 yuan, the buckle is 50 yuan, the baseboard is 200 yuan, and the free installation, the total cost of the floor assembly is 4,250 yuan. Calculate the individual construction costs of each project one by one, and add them together. The sum is the total cost. Note: If the user supplies materials or equipment by himself, he shall deduct the corresponding materials or equipment. After the price has been negotiated by both parties, the decoration contract can be signed. In the contract, the total cost of the package should be marked as one death. If there is a change, another increase or decrease should be made. Design fees There are reference standards for design fees At present, many decoration companies begin to charge design fees. From this year onwards, designers need to hold certificates, design fees to implement the "Beijing family home decoration design service standards and charges reference standards." Any designer who holds the architectural decoration design rank title certificate issued by the Beijing Municipal Personnel Bureau and the designer qualification certificate issued by the Beijing Building Decoration Association may charge the design fee for designing the home improvement project. According to the complexity of the design content and the requirements of the customer, the design and drawing shall be carried out according to actual needs. The design fee shall be fluctuating and adjusted downward. The general design of the general apartment covers an area of ​​80 square meters or less, and the project cost of less than 30,000 yuan (including 30,000 yuan) will be charged according to the project. The cost for each project is 500 yuan. More than four floors of duplex apartment and single-family villas with high-end decoration design covers more than 80 square meters (excluding 80 square meters) of interior design, according to the set of interior decoration area and according to designer qualification level engaged in engineering design design fee. The design fee is from 20 yuan/m2 to 50 yuan/m2. In this area, it is up to the design unit to master it.
