Drawing production process for refinery units in design institutes

This issue is a bit complex; it varies from one college to another~

What kind of image? ? ? ? So many drawings. . . .

Here’s something from the construction industry for your reference: generally, there are three steps – conceptual design, technical design, and the creation of construction drawings. 1. Scheme design: Understand the design requirements, obtain the necessary design data, draw the main plans, sections, and elevations of each floor; when necessary, even create renderings. It is necessary to indicate the main dimensions of the building, its area, height, the locations of doors and windows, as well as the locations of various fixtures, in order to fully convey the design intent, structural format, and construction features. During this phase, there is considerable interaction with the property owner and those who use the property; once the plan is finalized, it is possible to proceed to the next stage of technical design. 2. Technical design: This is usually unnecessary for projects that are not too complex. During this phase, the main task is to exchange information with other construction trades, put forward requirements, and coordinate relationships with various trades (such as structure, plumbing, HVAC, electrical, etc.), in order to lay a solid foundation for the subsequent preparation of construction drawings. In architectural design, this step requires construction workers to specify the detailed dimensions related to other technical specialties, and to prepare technical specifications for the building components. 3. Preparation of construction drawings: This is the most labor-intensive step in architectural design, and it represents the final stage in completing the project. Its main purpose is to create construction drawings that meet the requirements for construction, determining all the dimensions, materials, and design elements needed for the project. In architectural design, it is necessary to complete the entire set of construction drawings for the building. Once the final construction drawings are completed, they are reviewed, stamped with the seal of the registered architect and the design firm’s stamp, and signed by the designers, reviewers, and other relevant personnel. Together with other drawings such as those for structural work, plumbing, and electrical systems, these drawings can then be finalized. At this point, the architectural drawings acquire legal validity, and the relevant parties assume responsibility for the building designed.
