How many tricks are there in the decoration quotation? Let's look at all the friends who clear, half and all packages.

Pussy 1: Project unit price package? At first glance, this quotation is nothing, everything is clearly written, and it is correct to multiply the quantity by the unit price. In fact, this is a very irregular quotation, because its unit price is too general. ? The standard practice is to refine the unit price, and the main materials, auxiliary materials and labor are quoted separately, as shown in the following table:? The project unit price package will bring many disadvantages:? In some projects, the main materials are lossy, such as tiles and floors. It is normal to have a proper loss, but the loss of the main material does not mean that there is a loss of auxiliary materials and labor. It is more reasonable to price the unit price separately, and it also protects the interests of Party A. For example, the kitchen needs to be tiled, with an area of 27 square meters and a loss of 5%. Unit price of main materials 130/ m2, unit price of auxiliary materials 10/ m2, and labor cost 15/ m2. ? Decoration companies can tamper with the grade of materials. Some owners have made clear the brand of the main material after the death of the price card. Decoration companies can't get any income from the main materials, and they don't want to give up their own profits, so they have to make a fuss about the auxiliary materials. For example, * * brand inkwood paint-free floor is installed with keel. The decoration company quoted 260 yuan /m2, and the owner also went to 250 yuan /m2. The decoration company also agreed. When the floor is installed, the brand, material, specification and grade of the floor are all right, and the keel for installing the floor is really poor. Looking for the theory of decoration company, the decoration company replied that this keel was used in the quotation, but it was in the quotation. ? If there is any change in material procurement, the settlement amount with the decoration company can be well documented. For example, it was originally agreed that the PVC gusset plate of kitchen and bathroom would be purchased and installed by the decoration company, and a package quotation was adopted. The gusset plate+keel+labor cost is RMB * */m2. Later, during the construction, the owner proposed to buy the gusset plate by himself, while the decoration company was still responsible for the keel and installation. This is much more annoying, because the original quotation did not specify how much the pinch plate was, so Party A and Party B should negotiate again to see how much money should be deducted from the project payment. If it is classified quotation, only the price of the main material of the pinch plate is deducted, which can save a lot of time and energy for the owner. ? It can only be said that the unit price is divided into three parts: main materials, auxiliary materials and labor, which is only beneficial to the owner. The reason why the decoration company adopts such a package quotation is nothing more than to earn more profits, because some materials and labor costs are more transparent now. If you quote separately, the decoration company has no profit at all, and can only use the trick of "fishing in troubled waters". ? To think that this kind of quotation is the behavior of some small companies, many large home improvement companies in Nantong adopt this quotation method, and Netsail has so many package quotations from Tongcheng brand home improvement companies. If my friends show me this quotation, I will definitely not read it any more, so I can only ask them to let the decoration company make another one! ! ! If Party A signs this budget, it will be difficult to explain the future, even if you find something that makes sense. ? Tricky 2: Unknown material name and specification? There are two situations here: the first is to simply write nothing, just write the project, and leave it there for you to fill in the blanks without specifying what materials to use. ? Second, it was written but vague. For example, only * * brand polyester paint and * * brand aluminum gusset plate were written, without further explanation. The materials of the same brand can be divided into many models and specifications. A paint brand with a complete product line should have high, medium and low series in polyester paint. There are three kinds of aluminum gusset plates of the same brand: spray coating, roll coating and film covering, and the prices vary greatly among the varieties. Be sure to specify the specific information of the material. If you have a brand or model, please indicate the specific model, such as "Anyang D300 Interior Door". Some materials that really can't indicate the brand and model should indicate the specific specifications, such as "3×4cm Chinese fir keel". ? In the second case, there is also a case of confusing concepts. For example, when making cabinets, the cabinet board does not specify a specific brand, but uses E 1. E 1 is only a standard of formaldehyde emission, how to represent it? A similar example is the use of AAA level to represent blockboard. ? Decoration companies do this for two purposes. One is to substitute inferior materials, and the other is for customers to ask for replacement once they find that the materials used are not what they think. At this time, the decoration company turned against him. They can say that according to the original quotation, materials of this grade are used. If you want to replace more advanced materials, you can, but you have to pay more. Because the original budget table has no basis to follow, even looking for a decoration company theory will not have any effect. ? Formal decoration companies will clearly indicate the name, model and size of the materials used, and some will even add the grade and origin of the materials, such as "Kneyford waterproof paper gypsum board in Wuhu, Anhui, with a thickness of 9.5mm". ? With the diversification of information channels, the price of home improvement materials is becoming more and more transparent. If the materials in the quotation of the home improvement company are more specific, its profit rate will be lower. Only by taking this secret way can they get more income. This decoration is actually afraid of the word "serious"? Dorri's advice to the decoration company is "serious". Every project depends on whether the decoration company is specific enough, and it must be signed after all the product names are clear. ? Trick 3: The unit price is too high? There are only two situations here, one is that the material cost is too high, and the other is that the labor cost is too high. ? Regarding the price of materials, you can go to the market more and understand the market situation. Net sail is also mentioned in related topics. Recently, Netsail wants to hold a "shopping guide of forum mall" area, where you can also learn the latest prices of some decorative materials. ? Because the owners pay attention to the commonly used main materials such as floors and tiles, decoration companies often quote almost no water on these main materials, but raise prices on some uncommon materials and auxiliary materials. For example, a bucket of 20KG polyurethane (similar to asphalt) waterproof material is in its early 200 s, which can scrape 15 square meters, and the cost of main material is also 13. ? It is not a brand-name product with a very clear price, but an unknown product, which makes it inconvenient for consumers to compare prices. For example, the quality of Baidie PPR water pipe is very good, and its price has been very transparent in the market. The decoration company does not use white butterfly, but uses another unknown water pipe instead. ? Regarding the labor price, I have consulted the Municipal Price Bureau and the Decoration Association, but there is no reference price to provide. At present, we can only refer to the Shanghai labor cost standard. Hehe, we collected more information at hand, and combined with the quotations of many decoration companies, we compiled a "labor cost standard" in Nantong. ? Tricky 4: Is the loss high? The loss of materials is objective. It is necessary to find out where there are losses and where there should be no losses. If there is a loss, it is fraud. For example, materials such as floors, tiles and gusset edges are lossy. Latex paint is actually lossy, but this loss has been included in the unit price, so we won't report the loss separately. When decorating, it is already a finished product, and there is no loss of materials that can be installed without cutting and polishing. ? Losses are limited, generally not exceeding 5%. If it exceeds this number, it is suspected that there is water in it. ? Incidentally, the main materials of decoration projects such as tiles and floors are lossy, while the auxiliary materials and labor are not. Formal decoration companies will only add 5% to the main material price when quoting, without increasing the area and losing auxiliary materials and labor. Cunning companies will increase the area by 5%, so that the main materials, auxiliary materials and labor will increase by 5%. ? Tricky 5: unpacking items? When a project is divided into several projects, the unit price of each project comes down, but in the end, when the unit prices are added up, the total price goes up. ? For example, the latex paint on the wall will go through several processes. The quotation of decoration companies is generally a quotation for latex paint, including all the processes, but some companies need to refine it to several projects and report it separately. I have seen a decoration company quote like this on the road of workers and peasants. They divided the construction of latex paint into several items: putty, polishing and brushing. Moreover, several quotations are not written together, but written separately. You need to look carefully to find all the processes. They use Dulux Phantom Home Emulsion Paint, ordinary semi-finished putty, without primer, and all the quotations add up to 27.5/ m2, while the formal quotation of this grade of materials is about 18/m2. ? A similar example is the door cover, which generally includes painting. Some companies reported door cover processing and door cover painting. ? Tricky 6: Repeated charges? Item is to divide a project into several reports, and repeated pricing is to divide a project into multiple reports. ? For example, it is still an example of a door cover. Generally, the door cover is quoted at 70/ m, which already includes the painting fee, but a door cover painting project is added later, so the door cover painting will be charged twice. ? Tricky 7: Out of thin air? Construction projects or charging items that are obviously not available in the quotation. ? For example, when the second-hand house is renovated, the old floor tiles are knocked out, and the floor tiles are re-paved, it is necessary to level the ground with cement mortar. It is normal for the project of "ground leveling" to appear in the quotation, but this item can be omitted for the newly completed house decoration. The process of ground leveling appears in the quotation and belongs to the decoration company. ? The aluminum gusset ceiling includes labor costs, and the material supplier is responsible for the installation of the aluminum gusset. The installation fee has been included in the material fee, and the installation fee of aluminum gusset plate suddenly appeared in the quotation of the decoration company. The extra installation fee was hacked by the decoration company. ? There are countless examples of this trick, such as the cost of cutting tiles, the cost of mechanical wear and tear, and the cost of knocking on wall fittings. Tricky 8: Missing items? Deliberately underreporting the project, first sign a contract with the owner at a low price, and then ask for additional project funds on the grounds of ignoring the quotation in the early stage. ? Deliberately omitted some unremarkable engineering projects, such as skirting, waterproofing, wall drilling and so on. ? This is a relatively bad practice. Tricky 9: the number is inflated? When reviewing the quotation, the owner pays more attention to the unit price and less attention to the audit of the engineering quantity, so many companies make a fuss about the engineering quantity in order to obtain higher profits. ? When the project draws to a close, the owner will measure the dimensions of several major items, such as wardrobes, bookcases, walls and other key dimensions, and compare them with the quantities in the quotation sheet. ? What needs to be explained is how to calculate the engineering quantity of some projects, such as the area of latex paint, which needs to be communicated with the decoration company in advance. Some companies have removed all the doors and windows, while others have removed all the doors and windows. No matter which calculation method is adopted, it is necessary to communicate in advance to reach a * * * understanding of the calculation method of quantities, so as to avoid disputes between the two sides on this issue in the future. ? Tricky 10: packing items? You can often see such quotations in terms of "items" in the budget table? Personally, I think this quotation method is not desirable. Usually, the price of some projects with uncomplicated technology and few varieties of materials will rise a lot after quotation. In fact, these projects can be subdivided into small items, such as gypsum board modeling * * square meters, wallpaper * * square meters, ... The quotation of the decoration company is nothing more than trying to fish in troubled waters and earn more money. ? However, it does not mean that the construction project with item as the unit in the quotation is unreasonable. For example, the charges for installing sewer pipes and doors in toilets are all charged by item. These projects are all routine construction projects, and the materials and labor required to install each sewer pipe are roughly the same, so they do not need to be subdivided, so they are based on items. ? Pussy 1 1: the unit of change? Materials that should be sold in meters shall be quoted in square meters. Conversely, things measured in square meters should also be measured in meters. ? For example, 1.4m wide and 0.6m deep bay windows are paved with marble windowsills. The price of marble is 220/ m2, and the actually calculated price is 220×1.4× 0.6 =184.8. However, the decoration company takes "meter" as the pricing unit, and the unit price is still 220, that is, 220 × 1.4 = 308. The difference between them is 123.2 yuan. That's how a friend of Netsail Dongfang's new job fell for it. ? Mao Ni 12: The process is unclear? Many decoration companies offer consumers simple project names, material varieties, prices and quantities, and there are no key technological practices. You should ask the designer to add the technical practices in the budget book, or elaborate on the technical practices of each project in the budget. Because the specific construction technology and procedures are directly related to the construction quality and cost of home decoration. There are a lot of uncertainties in the budget book without technical practice, which will bring many troubles to the future construction and acceptance, and even open the "convenient door" for a few informal decoration companies to cut corners and shoddy. ? For example, the installation method of aluminum gusset plate is not specified. The normal installation method is suspender+light steel keel, but most aluminum gusset plates in Nantong market are installed with wooden keel+light steel keel. The installation of the former is more complicated than the latter, and the cost is slightly higher. Similar examples include the number of times of painting wood paint is not marked, and so on. ? The practice of these projects is not specific, which will bring many uncertain factors and bring many future troubles to the future construction acceptance. Everyone must ask the decoration company to indicate the specific construction technology. ?
