In the audit quotations, it is necessary to pay attention to items such as brush coating and paving which have a large amount of work. If the unit price increases by one or two yuan, the entire construction cost will increase a lot. For example, in the 60-square-meter paving project, the price of a square meter will increase by 5 yuan per square meter, and the entire cost will increase by 300 yuan. For example, for a coating, a 100 square meter type of apartment brushing will generally be more than 300 square meters per square meter. 2 yuan, the cost will increase by 600 yuan.
Anti-midpoint addition
Some refurbishment companies have lower quotations at the initial stage, but increasing the number of projects during construction will make the overall cost still higher. For example, deliberately select low-grade products during quotation, and require replacement during construction; when quoting, the length of hydropower pipeline is deliberately calculated, and the demand is increased later. In this regard, the owner can write the supplementary clause “The difference between the required settlement item and the budget item is within 5%â€.
Anti-material replacement
In material selection, it is necessary to indicate the names, brands, specifications, quality levels, unit prices, quantities, procurement locations, production dates, and shelf life of nine items in order to prevent the replacement of materials through the so-called “pillar replacement†during construction. In particular, it is necessary to pay attention to the projects provided and distributed by Daxinban, paints, latex paints, ceramic tile, wall tiles, kitchen and other decoration companies, and ask for quality inspection reports. Once problems arise, written proofs can avoid losses caused by material replacement. .
Anti-process ambiguity
The process is one of the important reasons that affect the decoration cost. The ambiguity in the process leads to the differences in the cost but also to the owner’s attention. For example, when dealing with a wall surface, at the junction of the bearing wall and the gypsum board inner wall, if no caulking is performed, cracks will occur; when the door pockets are opened, double-layer large core boards are used, but many decoration companies are in the quotation. None are reflected. Experts believe that whether the decoration company omits the project or promises the project but does not honor it, it will cause trouble and loss to the owner.
Anti-overpressure
Do not excessively lower the price, which will cause the construction team to have a rebellious mentality, and greatly reduce the decoration materials and quality. For example, the use of non-environmentally friendly large core boards, although the price has dropped, the environmental protection index will also decline; in addition, do not be lured by the construction team's low price quotes.

Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury. Toughened glass is a kind of safety glass.
Toughened glass can be made on customer's request, clear toughened glass, ultra clear toughened glass, colored tinted toughened glass, printed toughened glass, back painted toughened glass, frosted toughened glass, toughened Laminated Glass, toughened Insulated Glass, toughened Vacuum Insulated Glass and so on.
Toughened glass can be used for furniture, buildings, doors, windows, walls, table tops, fence, partitions, railings, balcony, balustrade, shower room and so on.
