Simple Sewer Profile

I have an horizontal alignment that I used to cut an existing ground line.  I will be using that for a sewer profile.  What can I put in the horizontal alignment that would show the same horizontal location of utility crossings.  Like a station tick or something.  I dont want to get into pipe networks.  Look like about 50 - 60 utility crossings

 

Thanks

I suggest using Pressure Networks for water, gas and even sewer utility crossings.

It is fast & efficient & plots the utility in the correct spot in the profile, as long as you have good depth information.

Yyou can place a cogo point, block, FL etc at these locations and project them to the profile view. I have made copies of eg - 3, eg-5 yada yada to project typical gas, electric, water elevtions.
I see you want to avoid Pipe networks, but you can make some down and dirty segments only at the crossing points?
Thank you

I agree with Joe's approach vs. trying to model all those crossings with pipe parts. You can style the plan view and projected profile objects and their labels to suit your needs without the overhead of having to manage all those pipe parts.

 

The downside to using projected objects is they have to be manually moved to the new location of the crossing if the pipe main alignment changes. In cases where the pipe alignment is prone to significant changes, using pipe parts might be a less cumbersome solution.

 

I like Joe's suggestion to create offset versions of the EG, each lowered to a utility depth. Then when you move a crossing, it's depth automatically adjusts according to the terrain (if you set it to use the corresponding offset surface elevation).

From my experience if you plot a utility at a depth that you think it is at, but don't know for sure, chances are you will plot it in the wrong position and possibly design a pipe run right through it.

That is true. Unless you locate them in the field you are taking an educated guess. Still, showing them in the plans draws attention to them, and if there are conflicts they can be addressed during construction. In cases where the alignment is critical, a field location should be established during design.

We typically don't show depths of utilities like gas, water, telephone, etc.  We strike a vertical line at the crossing point to call out possible conflicts.  We try to assume in design though, typical depths of utilities to avoid conflicts.  Now other sewer crossings are placed in the profile base upon interpolation between upper and lower manhole dips.

 

Thanks for all the advice.  I will give some of them a try.

Projecting a Feature Line, with elevations from the surface, into a profile view works just like Joe & Neil said.

Placed a tick mark at the existing ground line, at the correct station, from which a vertical line can be struck.

I haven't done that before, very nice technique to know. Thanks.
