Advanced Node Modeling
Thanks for the videos. I have not had a chance to review any but based on the volume, I have a feeling a good number of my questions will be answered.
I am going to breakup my questions into separate replies as to keep comments back and forth more clear and focused.
Stacked Nodes for Frame and Grates
I think this has potential as a work around in the interim. I need to do some testing on this but I definitely see value in it.
I have some reservations with this because not you are creating multiple stacked nodes on a structure for field data. I see some potential issues with sending this data out to the field. You will now have doubles stacked nodes and I think this could get confusing and lead to issues.

Modeling Sumps
I was thinking about this last night and I think the best way of handling this would be to add a field in MSI for manholes and call it offset from invert to sump or sump height. This would keep the current invert field as is but then when a user selects a specific manhole type CB or DMH, the program would calculate the sump based on criteria in the node material information. I think these values are going to typically be constant (for us usually 3 ft for CB and .5 ft for DMH). Maybe have the option to default to the values set and allow the user to override if necessary. I think sewer manholes would be an example of structures where the sump heights can varying among structures.
This would then give the user the correct vertical footage of the structures for trenching purposes. Now the trench is going to the bottom of structure (plus whatever user defined offsets at nodes). For material cost of the structure, I am not very concerned with the rings of the structure. The vendor designates the rings because this is a factor on what they can form and where the pipes intersect the structure. The only material cost occurred with the rings is the kent seal ( http://www.hamiltonkent.com/products/concrete-pipe-gaskets/kent-seal/) and you could probably put this as a factor of the vertical footage if it is not already considered by the vendor in their cost. I think this is a minimal cost.
Here is an example of a material quote from a vendor. The big cost components are the:
- base or sump
- vertical footage
- slab top
Boots have a cost but that is calculated based on size and number of pipes intersecting the structure. You would need to add these to the cost of pipe not the manhole. If you look below the boot in a 48 manhole is the same as a boot in 60 manhole so I do not think you need to take in varying cost with the size of structures. It is a factor of pipe size not structure size.
