Because the drawing standards of various companies in the decoration industry are not uniform, there are 100 material table standards for one hundred projects, which brings huge trouble for newcomers in the industry to understand the material table.

Therefore, kerooya decoration materials, in this analysis of the material table, some of the standard references listed are relatively common templates in China. The underlying logic of the material table is discussed, which is convenient for you to apply directly in combination with actual work. The main solutions are the following problems :

1. What should I do if I don’t know the purpose of using the table of materials?
2. What should I do if I don’t know the standard format of the material list?
3. What should I do if I don’t know the pits in the management and control of material files?

01
What is the decorative material table?

The material table is a table that summarizes, integrates and comprehensively controls the decoration materials of a project.

Generally speaking, there are two material tables involved in a project

One is the construction drawing material table that exists in the construction blueprint, which is what most designers often say;

The other is a separate graphic form that was compiled during the project design, which will contain specific model pictures, material details, and manufacturer’s contact information, etc., that is, the material list, material book, or material book that designers often say The material file, and the material basis of the material table in the construction blueprint comes from the material file.

The data in these two tables are in one-to-one correspondence. Under normal circumstances, the plan designer issues a material file, while the in-depth designer issues a material table for construction drawings.

Generally speaking, all the types of decoration materials used in the project should be summarized in the material table of the construction blueprint to facilitate unified management and reference. In principle, regardless of the size of the project, the decoration should be adjusted through the material table The material system is controlled and managed, which can greatly reduce the risk of overall drawing changes due to material changes in the later period.

In summary, two conclusions are drawn:

1. The construction drawing material table is the basis for guiding on-site construction, and the material file is the basis for compiling the construction drawing material table.
2. The biggest advantage of using the material table for material system control is that when material changes are involved for various reasons, the material number can be changed to avoid the risk of changing the material labeling of the entire set of drawings.

Standard reference drawing of the material table

A set of standard material tables must include: material number, material description, material size, use location, remarks these 5 essential elements, other options (such as: surface treatment, material model, supplier name, etc.) can be in this 5 The items are added based on the items; the standard reference drawing of the construction drawing material table is shown below.

Hotel project facing material reference

Many designers are surrounded by various material numbering methods on the market. For example, some pictures have curtains as CU, and some pictures have curtains as UP or FA, etc.;

In the face of such market chaos, we don’t have to worry about it, or even memorize what kind of material these material numbers represent, because the material code is usually the abbreviation of the material’s English name, and every design company has the same kind of material. My own different understanding, take curtains as an example, some people say it is fabric, some people say it is papier-mache, and some people set a material number for it separately;

But no matter what number it turns into in the end, we can find the explanation of its number in the design description of the construction drawing or the material table, as shown in the following figure:

PS: If you have to memorize a set of numbering standards by rote, you can also pick one of the two sets of templates we provide today. These two numbering methods are more commonly used in China.

We all know that the material file is mainly provided by the plan designer, and the main purpose is to restore the design effect. Therefore, it is mainly composed of 4 major sections: material number, supplier contact information, material content, and use area.

The material file is the basis for the compilation of construction drawings, so the elements contained in it must be comprehensive. Therefore, the material content will indicate the specifications and dimensions of the material, process requirements, fire resistance, special requirements, etc. Take the the carpet as an example. Let’s take a look at what the standard material file looks like. (The layout is for reference only)

The compilation method of the material table is: to count the material information involved in the project one by one, then summarize it in EXCEL, and finally check the correctness, and then paste it in the construction drawing material table or material file.

kerooya tips:

Under normal circumstances, if different surface treatments of the same material are used as facing materials in the project, the surface treatment item will be added to the material file or material table (as shown in the figure below), especially the bidding drawing and site When deepening, you need to pay special attention.

The purpose for the arrangement is:

Reduce the probability of errors when placing orders:
The construction drawings are not easy to make mistakes when guiding the on-site construction. The construction party will not confuse the materials that have not been finished with the materials and the installation location to reduce the risk of rework.

Reduce the probability of missed quotes:
When making the construction bidding budget, it is convenient to cooperate with the budget staff of the unit to calculate the amount, to issue the budget more accurately; because the surface treatment of the material is different, it directly affects the overall cost of the material. If it is not clearly marked, there will be under-calculations. Finishing processing costs, causing unnecessary duplication of labor and business disputes (this kind of thing is not uncommon in large-scale design projects, please pay more attention)

How to control?

After the construction drawings are drawn, in the final review process, there are often cases in which the material list issued by the deepening designer and the material file issued by the plan designer do not match the number; the most common ones are:

1. The material information does not correspond to:
   For example, the index number of the material in the construction drawing cannot be found in the material table or does not correspond to it; the finishing treatment, use part, and material quantity of the same material in the two sets of tables do not correspond.
2. There are omissions in the use of materials:
   For example, the materials used in the construction drawings cannot be found in the two sets of material tables.
3. Incomplete material information:
   When the material table was made, there was no complete description of the material information, which caused the later on-site personnel to make measures that violated the design effect based on their own experience.

For example, the grooved stone material is made of a smooth surface, and the horizontal pattern of the wood veneer becomes a vertical pattern, and so on.

The above situation is a summary of the problems existing in the preliminary archives from the perspective of on-site construction, so many designers do not know how much these details will affect the restoration of the later design;

And often these reasons are only in the design process because the two sides communicate poorly or carelessly and so on.

Therefore, before issuing the blueprint, we should pay attention to whether the material number, specification model, use part, and surface treatment of the material are missing or conflicted.

It is best to review the above information one by one in the final blueprint review link. If there is any ambiguity, communicate in time to avoid unnecessary disputes during the later on-site construction.

ps: In the actual process, the source of the disputes caused by the incompatibility of the materials is here, and the root of the designer and construction party’s Tai Chi is also here. I hope the designer will treat the above content as a list of elimination items and review the drawings. Take it out as a key investigation item

summary

Okay, the length of the relationship, what is the table of materials? What is the composition of the material table? And the topic of how to make a material list is here.

More system knowledge about material control, door watch, electrical watch, hardware sanitary ware form, etc. are included in other articles of kerooya.
