Pipe height tags from slab below and above

[liamb]

Hi All

I have a client who has asked me to tag my Sprinkler Pipework with heights from the Slab below and from the Slab above. As an example I have attached a screen shot from a CAD drawing sent to me as an example. The number -200 is showing the distance below the slab above (soffit) and the +2700 is the height from the slab below (floor). I am finding there are limitations when tagging pipework but i was wondering if there is a option that I could use within Revit.

The slab below should be easy and IMHO is enough information. The slab above might be tricky. What have you tried so far? Also, how do you plan on getting the offset from it? If you have a level that corresponds with the BOS, it should be very doable.

As you said the slab below is easy, its the slab above and presenting in a box with the - and + symbols. The reason for including it is to make installation safer on site. If the installers are able to measure from below or above, which ever is safer or easier it is quicker and safer to install. Most importantly the client has requested it. I am at a loss with the slab above especially in a situation where the underside of slabs vary. If the slabs were consistent thickness I assume I could set additional levels (for the slab above) to reference against.

I guess I was kidding myself into believing there would be an "add on" or Annotation Tag available.

The tag family is pretty easy. The labels can be prefixed. The reference to BOS is the hard part.

I still think it's overkill. The installers should be able to figure it out from field conditions. It's simple math.

Hi Liamb,

Did you end up getting this sorted?

I am looking at doing something similar...

IMHO providing 2 dimensions open yourself up to a greater liability.  Anyhow, you could use Ordinate dimensions for those.
