There are three main stages in the formation of architectural engineering drawings.
The complete set of engineering drawings is the basis for the construction unit to carry out construction.
.
The more complicated ones can draw a perspective view or make a architectural model.
This stage mainly involves conducting investigation and research based on the design tasks and requirements highlighted by the owner unit, collecting data, proposing design plans, and then drawing preliminary sketches.
Mainly including a complete set of engineering drawings and related supporting explanations and engineering estimates.
This stage is mainly based on the content determined in the preliminary design stage, to further solve technical problems related to architecture, structure, materials, equipment (water, electricity, HVAC, etc.).
The technical drawings drawn by each type of work during the technical design stage, along with the relevant design instructions and preliminary calculations, are called expanded preliminary drawings.
The third stage is the construction drawing design stage.
This stage is mainly to meet the specific technical requirements of engineering construction and provide all accurate and reliable construction basis, therefore it is also known as the deepening design stage.
The second stage is the technical design stage.
The first stage is the preliminary design stage.
This stage is also known as the expanded preliminary design (expanded preliminary design) stage.
The drawings and related documents in the preliminary design stage can only be used for research and approval purposes, and cannot be used as a basis for construction.
