Which is better, steel structure deepening design or steel structure construction?

Deepening design and construction are basically going to the construction unit, but the work they are engaged in is a little different. Let's talk about construction first. If you go to the construction unit, you have to go to the construction site every day, just like the builder, and you have to stay at the construction site when you go to work. As for the deepening design, it is a bit biased, but it is not the design drawing of the design institute. Generally speaking, the design institute has no drawings, or the drawings produced by this engineering design institute are very rough. Of course, we don't pursue this reason for roughness. Anyway, it is in this case that the construction unit needs to improve the drawings and complete other drawings by itself. This is the deepening design. We don't have to go to the construction site every day, but we have to draw and draw. If it is a big company, I think it is better to do in-depth design than construction. After all, construction is very abstract, but in-depth design is different. Like design, its requirements are very high, but of course it is lower than design. Moreover, in terms of treatment, with the knowledge of friends around me, the treatment of deepening design in construction units is very good, which is higher than that in general construction. But you should be prepared to work overtime to catch up with the map. Sometimes I may work overtime until two or three in the evening!
