Isometric drawing
Isometric drawing
(OP)
Hi,
I am an I&C engineer and we happen to have the problem that the detail engineering firma that has drawn all the isometrics has not taken into consideration the instrument data sheets and have drawn them wrong. My question if any instrumentation engineer has ever had to revise these isometrics as i am doing now. To me this has to be done by mechanical engineers.
thanks

Do you not have recourse with the firm that created the drawings?

If I didn't check these drawings, no on else would and my instruments would not be mounted correctly.
Although these has to be done I have told my project manager that this is not the job of an I&C engineer but all to no avail. Fact is If I don't do it no one else will.

In contrast, if the "data sheets" only included ordering information without dimensions and connection types, the instrument folks did not provide enough information to the drafter and assumed that someone else would research the component. I can easily see a drafter blindly picking an automated block from their drawing program instead of contacting the manufacturer to get the dimensional information. The drafter would just assume that the installer would research the components physical dimensions. In this case, the drafter was not provided with enough information and may not have known that he was supposed to do the instruments engineer job of researching the specific components dimensions and connection type.

As always time is money so we had no choice but to go ahead with building the HW before even checking the drawings, and of course they were not checked in time due to lack of resources, personally all i checked were the P&IDs with up to 7 revisions as well as the instrument data sheets. If you are interested to know the plant is a Biodiesel production plant.
btw, thanks to you all for getting involved in this discussion.

The phrase "business decision" can be read as: "If things work out okay, the business majors get to wear their hero suits for a while. If things go badly, the engineers get all the, er, credit."
Costs associated with recovery from an unfortunate business decision are, of course, never formally associated with said decision.
