We currently utilize InRoads SS2 for our design work (about 15 years experience with various versions), and have investigated moving up to SS4. Our work consists almost entirely of site grading: yard grading, parking lots, stockpiles, basins and layered closure caps. We rarely design very simple roads, but often utilize the roadway tools to design drainage channels which occasionally have varying cross sections, nor do we utilize features very heavily.
In my (limited) investigation, the OpenRoads paradigm appears to be geared more to road design, and site work doesn't appear to be as straight forward as SS2. The one thing (I think) I really like about SS4 is the fact that data is stored in the design file.
I would appreciate opinions and discussion from those who have used both products to help in our decision process.
Thanks in advance.
