In order to improve the success rate and speed up the signing, decoration companies usually make full use of the most sensitive part of the price. There are a lot of omissions, insufficient calculation of the quantities, and no material selection, which lead to the difference between the budget price and the final price. Due to the loopholes in the traditional quotation method, in order to gain greater benefits, the later construction personnel maliciously increase the quantities of hydropower projects. Even if the company includes the budgeters, they can not control the increase of the later quantities.

Many customers feel that the designer is not important, especially some customers who just need it may have relatively low requirements for the modeling of the opposite or top surface, and even feel that there is no need to design. But familiar do not know, modeling design is just a part of the role of designers for decoration. Designers have played a decisive role in the whole process of decoration work since they measured the room on site. Designers with less experience and irresponsible work may cause data loss and inaccuracy when measuring the room, such as floor height, window height, beam, pit distance, pipe distance, location and size of strong and weak current box, stair steps and other details, which can never be lost, And the need for accurate measurement, after the plane program and detailed design, must be taken into account. If there is a lack, it will certainly have an impact on the budget, and even draw a question mark on the feasibility of some construction, resulting in irreversible adverse consequences.

The communication between designers and customers is essential in the whole decoration process, and whether the communication is smooth and sufficient is directly related to whether the decoration can be carried out smoothly. And the hidden danger of price, also produced with the designer's "Silence".

For example:

a、Whether equipment is needed, if central air conditioning is used, additional 6 square wires are needed.

b、Different choices of window sill marble have huge differences in price.

c、Different laying methods of wall and floor tiles and undetermined size of wall and floor tiles will also have a great impact on the labor cost of paving.

d、The places that affect the layout need to be communicated in time, otherwise it will cause the later rework and greatly affect the cost.

e、The floor is solid wood and needs to be laid with wooden keel; The floor is composite and needs to be leveled.

f、"Flat roof", "modeling top", "bare top", and other different ceiling costs change with the shape, and so on.

All of the above problems are completely avoidable. In order to hide people's eyes and ears, decoration companies evade responsibility in case of disputes later, "to be determined", "estimated", "settlement according to actual" and other words emerge as the times require. Decoration company successfully for their own irresponsible and unscrupulous means to seek benefits to find the best way, customers can only for their own unprofessional, and the original is not careful and bear to pay the expenses seriously inconsistent with the budget.

According to the traditional company practice, in addition to a substantial reduction (additional management fee will be paid after exceeding a certain ratio), the final price will be higher than the budget price, and the amount higher is not a small amount. More importantly, when signing the contract, during the construction process, we do not know where the increase will be, let alone how much.

In the budget, wall plastering, water and electricity slotting, ground leveling, removing the original coating layer, adding one degree of batch inlay, switch socket bottom box, there are always a few items not included; The water and electricity sector will certainly increase, and not increase When it comes to settlement, we never know how much to increase; Window marble, logo words, frosted paste, special wall decoration (hollow board, stainless steel, ecological wood, etc.), if the quantity is small, it will not be done, and the owner needs to purchase it; If the budget indicates that the materials are to be determined, it will be decided by the project manager on his own initiative if he doesn't pay attention to them, and the price is unknown, and he doesn't like the style, etc.
