Questions about automated design
Thread Content
Is automated design divided into preliminary design and construction drawing design? Is it still just construction drawing design? What is included in the preliminary design?
The preliminary design you are referring to should be the selection and specification design of various instrumentation and equipment required for the process flow, including the specifications for different instruments, automatic control valves, and control systems. The subsequent construction design is based on the specific specifications and dimensions of the equipment purchased earlier, to carry out the installation planning. This includes the statistical design of various installation materials, as well as the design detailing how each instrument, device, box, cable, pipe, tray, and logical control element is to be installed. Hope this helps!
Of course, feasibility study, preliminary design, and construction drawing design. Refer to standards HG/T20636, HG/T20638, etc.
The strict requirement is to distinguish between preliminary design and construction drawings. The preliminary design involves conducting site surveys based on the approved design brief, and preparing the preliminary design documents. It mainly involves providing suggestions on construction plans and preparing design estimates ； Detailed design (construction drawing design) mainly involves further specifying and refining the design concepts and technical decisions established in the preliminary design, by providing drawings and other materials necessary for construction as well as a construction organization plan. The preliminary design mainly includes instrument data sheets, material lists, etc
