Successful Equipment Model review

[CodeConfused]

I am a mechanical engineer that has recently moved from piping stress/spec/material role in piping, to the lead piping designer position. I am currently working in the estimate phase, before the estimate is complete I am to conduct an "Equipment Model Review" with the client in the 3D model. I would like input from the fine folks here as to what makes a successful model review, from both the client perspective and the consultants perspective. I understand that the primary purpose is to prove the layout, and receive comments with respect to equipment access, maint., construction, client preference, etc... Can the masses provide me with a general breakdown and overall objectives that lead to a successful design review. After all, the client and I are interested in the same thing, a well designed, ergonomic, profitable project. Any and all input would be greatly appreciated.

CodeConfused,

I'm a pipe stress guy myself, though I've sat through a number of model reviews over the years. At the equipment model review level, some things I would consider:

checking spacing, especially between things like pump pairs or exchanger banks to insure sufficient clearance (the client may even have specific standard requirements) for access and operations.

Placements of manways on columns and coverages for column platforms - again, accessibility, ladders between platforms, access to things like level gauges that may need valves blocked for maintenance.

Spacings for equipment/crane access for maintenance.

Along with the above, sufficient space for tube bundle pulls for exchangers with removeable bundles. And, clearance above those bundles to lift them away.

And, while the "equipment" review shouldn't at this time be focused on the detailed piping layout, you should plan to have at least major lines in with preliminary routings so that the client gets a better sense of scale and how much free space there will really be. A layout that looks clean and wide open can quickly become a virtual confined space when it gets filled up with pipe.

Ultimately, your goal at this point is to get those foundations fixed and the equipment locations nailed down so that you aren't blowing away design work down the road and back tracking because the equipment isn't placed properly.

In our 3D models, the designer will drop in copies of a 6' tall standard man in various locations as it helps provide a sense of scale that can be more easily related to.
