The design preparation stage is mainly to accept the entrusted task book, sign a contract, or participate in bidding according to the bidding requirements; Define the design cycle, make the design plan progress, and consider the cooperation and coordination of various related types of work; Clarify the use nature, functional characteristics, design scale, grade standard, total cost and other design tasks and requirements of interior design tasks, as well as the indoor environment atmosphere, cultural connotation or artistic style to be created according to the use nature of tasks;

Familiar with design-related specifications and quota standards, collect and analyze necessary data and information, including on-site investigation and visiting similar examples.

When signing the contract or formulating the tender documents, it also includes the design schedule and design rate standard, that is, the percentage of the interior design fee charged by the owner to the total investment in interior decoration.

2. Scheme design stage

On the basis of the design preparation stage, the scheme design stage is to further collect, analyze and apply data and information related to design tasks, conceive ideas, carry out preliminary scheme design, in-depth design, and analyze and compare the schemes.

Determine the preliminary design scheme and provide design documents. Indoor preliminary scheme documents usually include:

1, plan view, common scale 1: 50,1:100;

2. Indoor fa? ade development, commonly used ratio 1: 20,1:50;

3. For the top plan or bottom plan, the common ratios are 1: 50,1:100;

4. Interior perspective view;

5. Model room for interior decoration materials;

6. Design intention and cost estimation;

These are all realized by CAD, 3Dmax and Photoshop. If you want to do it, then you should understand that the preliminary design scheme needs to be approved before the construction drawing design can be carried out.

3, construction drawing design stage

In the design stage of the construction drawing, it is necessary to supplement the necessary drawings such as plane layout, indoor elevation, ceiling, etc., and also include the detailed drawings of structural nodes, details, equipment and pipeline drawings, and prepare the construction instructions and cost budget.

4. Design and implementation stage

The design implementation stage is also the construction stage of the project. Before the indoor engineering construction, the designer should explain the design intention and technical disclosure of drawings to the construction unit; In the process of project construction, it is necessary to check the construction situation according to the requirements of the drawings, and sometimes it is necessary to make local modifications or supplements to the drawings according to the site conditions; After the construction, the project acceptance will be carried out in conjunction with the quality inspection department and the construction unit.

In order to make the design achieve the expected effect, interior designers must pay attention to all stages of design, pay full attention to design, construction, materials, equipment and other aspects, and be familiar with and pay attention to the connection with the architectural design and facility design of the original building. At the same time, they must coordinate the relationship with the construction unit and the construction unit, and get communication and understanding on the design intention and conception, so as to achieve the ideal design engineering effect.
