As built drawing of pe pipeline.

thread378-257960: Terminology; Piping Plans vs. GA's.
Can anyone send me an example of these drawings and explain if P&ID's are a as built drawing??
Thanks

The pipe material should make very little difference, at least much less difference than letting a surveyor do it would.

There is not a specific P&ID for a PE pipeline. PE is a material and will be annotated in the line number. The link below gives you images of typical P&IDs

As you say P&ID's are devoid of dimensions and piping details, however once came across a Project Manager who asked for an accurate Material Takeoff to be done from a P&ID.He could not understand why this was not possible. They live and work among us!!!!

DSB123, Right! "Men In Black" is closer to the truth than most realize

General Arrangements will most likely not need any, or maybe a little work.
If the surveyors have done any as-built work, then I would guess that they have located the pipeline's features according to MP or KP (mile post, kilometer post) stations and elevations, and/or perhaps GPS coordinates. I wouldn't trust them for anything else. All piping features and equipment should be verified as-built, in place by someone that understands piping.
Piping Plans will most probably need as-built info markups and correction. All information joint features, tees, valves, diameters, wall thicknesses, class factors, materials should be tied back to their exact locations as they have been shown on the drawings, dimensions and any other differences corrected. In other words, correct all the drawings and information so that all dimensions and actually all information is shown EXACTLY WHAT was built and WHERE.
If your scope of work is only for the equipment, or one piece of equipment, then you must verify only the equipment drawings and their information, otherwise you should be prepared to do all the above.

Alignment sheets have what Amanda pointed out along with land ownership and geotechnical data such as water, sack breaker use, high consequence areas, etc.

RE: As built drawing of pe pipeline.
@Amanda: As-builts could be for any structure but when talking about the transmission pipelines, then they are in the form of the alignment sheets, including coordinates, levels, material, lining, coating, thicknesses, etc of the pipeline. So you can say that they are plan and profile drawings based on the constructed state. Land surveyors would only provide the spatial data but the rest is done by a technician (engineer) by feeding data to the drawings. You can have as build drawings for other items in a pipeline project such as valve chamber as-builds.
P&ID is something different. it's Piping & instruments and BigInch and others defined it well. In the projects that I've worked, I've never heard of as-builds for P&ID but "final" P&ID. As-builds always have a dimensional perspective for me which P&IDs don't.
RE: As built drawing of pe pipeline.
does anyone have an example of a dimensional layout for a pipeline? this would help me know where to start.
Many thanks for all the help.

After you talk to an older onsite operator or two, you find out, "Oh, that change was made because we needed a jumpover to provide A to B, so we did it on maintenance budget. It's never been a problem." At that point you start to wonder what else is not documented.
I'm hoping that cheaper laser/cloud scanning of existing facilities will correct this eventually.
In my experience there's nothing worse than not knowing what's in your plant when you go out looking at it.
