When refurbishing it, the construction team will inevitably ask for a quotation from the construction team. The owner should master the scientific audit method, review the construction team's quotation, control the total renovation price, and avoid spending money.

First, the total cost estimate
Households should establish a reasonable investment in decorating costs in advance in accordance with their own economic conditions while considering the basic functions for use and reflecting the atmosphere of home furnishings.
Second, the choice of design options
In the decoration preparation stage, several decoration construction teams are selected for design and quotation.
It is best to have experienced engineers to check and do a good job in comparison and optimization of design options.
At the same time, the industry is mainly involved in the design, according to their own ideas to choose the right design program, pay attention to the application, aesthetics, economic, environmental protection requirements, a good program is not only clever, but also economic and practical Caixing.
Third, must sign the decoration contract with the construction team
The decoration contract is an effective means to control the decoration and construction cost. The owner can not only have verbal agreement with the construction team, but also sign a contract with the construction team to clarify the responsibilities, rights and obligations of both parties. Both parties' approved bids should be attached to the contract. The construction team can not arbitrarily change the design standards, use less-required materials or ask for prices in construction.
In addition, it is stipulated in the contract that the cost will not be adjusted within a certain range of change, so as to avoid the construction team raising the cost through design changes.
Fourth, the use of materials, process clear
When requesting renovation construction team quotation, the specification, manufacturer, size, quality grade, and craft level of each sub-project should be specified.
There is a big difference in price between different grades and different quality grades of the same material.
Such as high, medium and low price of polished tiles from 40 yuan per square meter to more than 100 yuan, different quality levels of qualified products and superior products are also a difference of 10-20 yuan per square meter.
Without a clear specification of the material, manufacturer, size, and quality level, it is easy to be deceived by the construction team.
It is also important to clarify the level of technology.
Such as floor tiles leveling layer of 20mm thick and 30mm thick price is bound to have a difference, the wall surface latex paint and dust throughout the number of interior doors used solid wood door or plywood door outside the paste solid wood splint, wooden door brush varnish times.
Different process requirements will directly affect the unit price.
In addition, whether the materials used by the decoration construction team are environmentally friendly, whether they are harmful to the human body, whether the formaldehyde content of the splint binder exceeds the standard, etc., also affect the price of the materials. Therefore, the environmentally friendly materials should not be used because they are inexpensive.
Fifth, the decoration area to be estimated
The ratio of the general indoor area to the wall surface and the area of ​​the ceiling brush latex paint is approximately 1:2.5 (the kitchen/toilet wall is covered with tiles).
In this way, it can be estimated whether the coating area reported by the decoration construction team is too outrageous.
Floor tile area accounts for about 90% of the indoor building area.
Sixth, unit price estimation
For example: 1:2.5 cement mortar leveling 20mm thick, cement plaster paste 600 × 600 polished tiles, labor costs, material fees, machinery fees, polished tile leveling layer and other costs, the market price is about 25 yuan per square meter.
The price of polished tile materials is 63 yuan per square meter (according to the general renovation standards, 5% loss has been calculated).
Consider the construction team's taxes and management fees and profits of 10~15%.
That is, (25+63)×(1+15%)=101.2 Yuan/square meter.
In this way, it can be judged whether the decoration construction team's quotation is too watery.
If you choose the brick specifications, brick quality levels, different construction processes can be converted to the unit price.
Seven, additional costs
The construction team sometimes attaches fees such as garbage cleaning fees, material handling fees, taxes, and management fees to the quotation sheet.
The landlord should distinguish the cost of the lump sum price from those calculated, and those costs were not calculated to prevent the construction team from riding on muddy water to fish.
Before the decoration, the owners should run the market frequently to understand the market price of the main decoration materials so that they can take the initiative in reviewing the quotation of the construction team.
At the same time try to avoid excessively lower prices, so that the construction team is not profitable, so as to increase income by cutting corners, shoddy and other means.
The above is my own experience, and I hope to be helpful in reviewing the owner's decoration quotation.
