Teach you to read through the decoration project budget book
In home decoration, the decoration company often provides the user with a design proposal and a budget book before signing the contract. This budget book is a basis for users and decoration companies to negotiate, if the user can "eat through" the budget, and based on this and the decoration company bargaining, not only can save decoration budget, but also in the signing of the renovation contract, prevent many construction Problems.
The detailed budget corresponds to the drawings. Each project that will be drawn on the drawing sheet will be reflected in the budget book. The brand, model and type of the main material will also be identified on the drawings and budget book. As long as the user is based on the actual area, as well as the variety and price of the decorative materials, it is easy to understand whether the decoration company “overstated the risk of fraudâ€. However, it should be pointed out that according to the general engineering losses, 5% to 10% of the decorative materials are normal.
In addition, some projects that did not appear on the drawings, such as the transformation of the circuit, the dismantlement of Lighting fixtures and sanitary ware, will also be reflected in the budget book. The user can approve the budget according to the specific size on the drawing. It should be noted that the unit price in the budget book is generally the price after the fee plus the user, and the user can ask the decoration company about the pricing process.
A decorative budget statement contains at least four parts:
(1) The construction project and the location of the project. Such as "paving bricks", to indicate where the shop is located.
(2) The scale of the construction project. Such as "paving bricks," a total number of areas to shop.
(3) Production standards for materials and processes used in construction projects. Including major materials and auxiliary materials. For example, what brand is used for paving bricks, what bricks are used, whether it is tiles or marbles, what materials are used to fill the joints, whether the tiling process is dry or wet, and what are the process standards?
(4) The artificial unit price and material unit price of the construction project. Such as "paving bricks", artificial guidance price per square meter is 30 yuan, the price per square meter of brick depends on the selected materials and brands.
However, users should not think that everything is included in the budget statement. In fact, this is only a budget framework, and its content is the key. The following are the issues that users should pay special attention to when reviewing budget books:
(1) Whether the project is complete or not <br> When some designers are doing budgets, they intend to omit some of the projects, giving the user a feeling that this decoration company is inexpensive. The user wants to verify whether all the projects in the budget are complete. Is it right to list all the things to be done on the budget list? Are there any reports of missing a door or missing the kitchen wall tiles and the kicks in the bedroom? Lines and other phenomena, these missing items to the site construction, certainly still have to do, users will inevitably have to do additional procedures, to increase unexpected expenses.
(2) Units of measurement affect budget results <br> Users should take note of the unit of measurement in the budget book. In the production of furniture, the difference between the decoration companies is relatively large, such as a large wardrobe or bookcase, some companies use "Yanmi", and some use "square meters." At this time, we must pay attention to it, because the furniture calculated in “square meters†is often calculated by multiplying the unit price by the unit price regardless of how high the width is. The furniture calculated by “Yanmi†is highly limited.
(3) The drawings and budget should be the same size. <br> Users should refer to the drawings to check the specific number of each project in the budget book. For example, the floor tile calculated from the dimensions on the drawing is 50 square meters, then the budget book should be about 50 square meters, and the data calculation should be quite rigorous and accurate. Graph paper is 50 square meters, while the budget book is 55 square meters. This is an obvious error. It should be noted that the first step is to ensure that the drawings are accurate, that the drawings are inaccurate, and that the budget is certainly not accurate.
(4) Material and process specification should be specific <br><br> The easiest way to prevent moisture from being quoted is to check whether the quotation has only price description and there is no “standard for material structure and production and installation process technology†that should be specified. Take the most common wardrobe production project in decoration as an example. Currently, the price difference between the highest price and the lowest price in the market quotation is a few hundred dollars. The reason why the price difference is so great is that the manufacturing process differs from the materials used. There are joint venture boards and import boards. The import boards are divided into Taiwan, Malaysia and Indonesia. In addition, there are sandwich panels and large core panels in the splint, and the two have larger price differences. If you ignore the manufacturing process technology standards, how can you ascertain the moisture level of the price without clarifying that the closet is made of PCT, 12%, 15% PCT board structure, what brand of paint is used, brushed paint several times, etc.? There is a lot of uncertainties in the budget book that does not include technological practices. It will cause many problems for the future construction and acceptance, and it will also give a few irregular decoration companies to cut corners and cut corners, and create a “convenience doorâ€.
(5) Area Estimation <br> Some decoration companies deliberately overstate the construction area in the budget to obtain higher profits. Especially on the wall, a small number of decoration companies will report more brushing area. Generally, the ratio of the floor to the wall of a space is 1:2.4 to 1:2.7, and some decoration companies even report 1:3.8! In addition, according to previous practice, the area of ​​doors and windows was calculated as 50% of the area covered by the painting. In fact, many families now pack doors and windows, and there is no need to brush around the doors and windows, but some decoration companies still account for 50% or even 100% of the wall painting area.
(6) Price Factors <br> There are many users who choose a decoration company and only compare the prices on the budget book. Which one has the lowest price, let which one do it. In fact, the price on the budget book is inseparable from the choice of materials and process. Simply choosing the decoration company with the lowest price will often bring irreparable losses to the user. When a user reviews the price quoted in the budget book, he must take into consideration the brand, model, and construction process of the material in order to arrive at a more objective assessment.
(7) Related expenses <br> At the end of some budget books, there will be items such as "mechanical wear and tear," "site management fees," "taxes," and "profits." These items are in fact unreasonable charges. . “Mechanical wear and tear†is inevitable in the decoration. “On-site management†is what the decoration company should do. Both of these expenses have actually been allocated to each project and should not be requested from the user. The principle of “who manages and who pays taxes†should not be paid by the user. The “profit†is calculated separately, which is the calculation method of the public building renovation quotation. Currently, the decoration company has put the profit into each construction. Therefore, it should not be repeated.
(8)Special circumstances special budget <br> Wall cracks: Large area cracks treatment is to be charged separately. In particular, full-filled gypsum board, usually more than 30 yuan per square meter, this fee is often not reflected in the budget, and to the site construction according to the actual situation was proposed separately.
Tile mosaic: Some families prefer to use different colors to create a certain pattern in the paving tile. The cost of this spell is usually presented at the time of settlement. Waterway and Circuit Construction: In the budget, the cost of renovating waterways and circuits is usually a small portion of the advance payment, and when the project is completed, it will be settled according to the actual amount.
