I have a corridor but I am trying to add the proposed culverts in there.
I tried the Subsurface utility but it does not have any nodes/conduit templates for box culverts, so that did not work.
Then I tried to just draw in the culvert and assign profiles/elevations to it but that does not seem very intuitive.
I read something about using a template but was not sure how to go about that.
Should I make a corridor for every culvert with its own culvert template?
I think that would work but I am worried that would take a lot of computer resources.
I have exact same question now, did you find the answer to it?
No.. I have not got any answer from Bentley or any One. Still looking for solution.....
Hello Krishna. The original post raised a number of potential issues, which is why the initial response requested further information. In Ben's second post he said that his initial need was to have the culvert displayed in the model. This can be done using ORD Subsurface Utility tools. However, to use those tools, there is much that you may need to set up in order to use SU. For example, the catalog of available box culvert sizes may not include the particular size you need. You may need to edit the Conduit Catalog so that it contains an option with your particular box culvert dimensions. Also, before placing the culvert, you will need to place a node at each end, because a culvert is a type of "conduit" which is intended to connect two "nodes". The nodes, for example, could simply be two headwall nodes. The information needed to place these nodes (including both 2D and 3D cells) needs to be available to SU, or created so that it is available. As a work-around, you could simply use a node that is available with the delivered Bentley workspace, and turn off the levels they use so you would only see the box culvert itself. I suggest utilizing the Bentley Learn tutorials to get familiar with SU. It can do what you want to do, but there is definitely some set up and training needed.
As for the headwall and wingwalls and associated grading pictured above, it may be better to layout this in CADD rather than trying to use ORD. Due to the many variables involved (box dimensions, number of barrels, skew angle, embankment side slope, etc), there is no way to create a catalog of headwall/wingwall node options to cover every situation. Many DOTs will take the time and effort to create cell libraries with standard headwall/wingwall configurations for specific combinations of box size, number of barrels, skew angle, and side slope. If you have such a library available that meets your needs, great. If not, it is a lot of work to create one.
As for a workflow for the end conditions, here is a suggestion:1. Use ORD SU tools to layout culvert.2. Cut profile along culvert (this can be done easily in SU) to verify adequate cover along culvert and adjust culvert start and end points.3. Using Microstation 2D drawing tools, layout culvert headwall and wingwalls to verify that grading works. May need further adjustments of culvert end points at either end. In order to do this, you will need to display the contours for the terrain model representing the roadway embankment.4. If you really need to develop a terrain model that represents the grading at the headwall, then use terrain modeling/grading tools to do that. 5. If you really need the headwall and wingwalls to be represented accurately in 3D space, then you will need to create 3D cells for that purpose which can be placed as nodes in SU.
In my experience, steps 4 and 5 are not typically done. It is not usually necessary for the purpose of creating a set of construction plans.

Granted that there is a LOT of work to set up SU nodes, but once that work is done on the back end, models cannot only be presented accurately, but also quickly. Attached is an 18' x 11' RCB. The model is made up of ONLY SU nodes(one 2D plan headwall, and one 3D headwall) and an entry for the size of this structure in the Conduit Catalog. Using Subsurface utilities, we can lay out structures like this in a matter of minutes and run a hydraulic analysis as well. Furthermore- and what is most important about this approach- is that the information within the model is true "model-centric"; that is, it is true to the future of Construction Information Modeling (CIM). We have spent a great deal of time building these sorts of models, but the end result is future-forward and extremely valuable:
Here is another series of storm models which are attached to existing structures (also modeled in SU):
One of the nicest things about ORD is clash detection, which is illustrated here:
Of course, our clients may or may not see value in such an approach (for now; I feel that it will be imperative in the years to come), but for us Subsurface utilities has been a fantastic and extremely valuable tool! I must give thanks to Mr. Robert Garrett of this forum for inspiring me to tackle this process a year ago.
Mark, Love your philosophy here. Keep up the great work you seem to be doing here.
Thank you for your kind words, Matt!
