When you submit your project for optimization you are waiting for a good solution to be returned. Sometime projects are submitted where SITEOPS finds errors either in grading or stormwater piping. So that you know if you have an error and what kind of error it is, a new section is added to the solution area.
This area will have three states:
1 - Empty - means SITEOPS found a solution that is free of error
2 - Grading - means SITEOPS was not able to find a suitable grading plan meets requirements. You will need to open revision and make changes to solve grading issue and then resubmit.
3 - Piping- means SITEOPS found a grading solution that works but was not able to pipe per requirements, You will need to open revision and revise stormwater connections.
