Recently, our factory is going to implement a incinerator project, and I, though unskilled, serve as an electrical and instrumentation engineer. But when I contacted the DCS manufacturer, they only sent our purchasing department a total price list; there was no separate price list for each card, chassis, etc. I didn’t even have the opportunity to compare prices. Is this reasonable? It was made by a DCS manufacturer
If you think it’s reasonable, then it is reasonable. If you think it’s unreasonable, then it is unreasonable – after all, you are God. . .
You can ask them to provide a detailed itemized quote for this. It’s tough to do business in DCS these days with few projects available; they should be willing to cooperate with you
You can bring up any ideas you have to them – it’s not excessive at all!
Doesn’t bidding mean specifying a brand? Domestic or imported?
Now DCS costs the same as color TVs – which brand is still that great?
Required: component layout diagram, wiring diagram inside the cabinet, safety barrier layout diagram, safety barrier wiring diagram, control cabinet, operator station configuration list and installation diagrams
A quote should include the quantity, unit price, and a list of specifications – for example, the number of cabinets, the number of power supplies, the quantity of each type of card, the model and quantity of safety barriers, the number of terminal blocks along with their unit prices, the number of relays, and so on!
First, you need to figure out the relationship between your boss and the manufacturers; generally, those who have been in this field for a long time are on good terms with the managers or leaders of the manufacturers. Of course, within this general framework you can make any request to him; no detail is too subtle, because no matter how detailed it is, he will find a way to keep the price within his control – that’s the rule of the industry
