How can construction staging be modeled in GEOPAK SS4? Before OpenRoads, we typically had plan sheets and typical sections to show staging for lane shifts, temporary pavement, crossovers, etc. Quantity calculations were quite cumbersome for each phase. How can OpenRoads make this more efficient? Would each phase be modeled as a separate corridor? Each with its' own terrain model?
Thanks in advance,
Brian
Brian,
What you are asking is quite a "age-old" issue. Here is one older solution (SS2, pre-OR) that would have to be modified a bit to work in OR, and would not get you anything but final design broken into pieces. The temporary detours, etc would still need to be created as individual corridors, but that was true both pre-OR and now.
The one spot where OR could be leveraged as a benefit over SS2 would be with corridor clipping. Let's say you are doing partial construction and only half of the road will be built in Ph1. Well, you could reference the overall design into your Ph1 file, then clip out the part not being built. If you needed a temporary end condition along this edge, you would need to create a linear element that uses the proposed pavement (or FG terrain) as its vertical, then run a linear template (or corridor) along that element. This is just one example, there are probably others as well.
I will also add that the good news is that Bentley is fully aware of the difficulties involved with this process and are looking into more efficient solutions to provide our users.
Brian, this is very helpful. Being that its being two years from this response, have you found a more efficient way of stage construction in inroads?
Thanks. The tool keeps making the program crash in my corridor files. In a clean file with a corridor the tool runs but doesn't create any volumes.
I am currently in the process of creating staged cross sections and wanted to use this method. However, it seems the corridor clipping tool cannot be used on a referenced corridor. I have several sequential corridors that I wanted to reference into my MOT drawing and clip to cut sections. Of course I do not want to clip the original corridors, as they are the proposed design. Is the best option to create copies of the proposed corridor DGNs and clip them? I would rather not do this as I don't want to keep track of changes across these duplicate drawings. Or is there another workflow that I am missing?
You need to use Clip Mask tool to do it. Corridor clipping tool can only be done in an active corridor in which you use another overlapping corridor or clipping shape as clipping area.
Using the Clip Mask tool would not help me in generating an MOT model though, correct? I need to create cross sections for two phases of construction and wanted to avoid remaking a lot of templates for each phase. Do you know of any other methods for clipping a model to generate phased sections?
My understanding is it will help you generating your desired MOT phases. Clipped areas wont show on your cross sections. The only other method that I know of is creating a corridor / corridors for each phase as described by Jason Harkless above. Any temporary end conditions/pavements/etc can be done by hanging them onto temporary alignments created for each phase (perhaps along the clipped areas).
