    Question Non-sequenced Change Order approval documentation and modeling workflow in the Revit model.

    The authority having jurisdiction on our project may approve Change Orders out of sequence, causing our model to have elements in various states of approval during Construction Administration (CA).

    Does anyone have suggestions for Best Practices regarding the modeling workflow in Revit?

    • Design Options? (Cumbersome and dangerous if not implemented accurately, other caveats?)
    • Work Sets? (Entire building is modeled with numerous links, +>480mb)
    • Phasing? (Too limiting, need to shift approved phases to current out of sequence created)
    • Parameters? (?)


    Thanks!

    Forgetting Revit...how would your firm respond to this situation? Do you alter drawings or a drawing log to indicate approval? If so you can store values as Sheet Information and "mark" any approved sheet as such when it occurs with a date and comment? Or are you asking how to create the model changes to document change order information prior to being able to review for approval?

    Thanks for commenting Steve.

    Our issue is how to move forward in the model as change orders are approved out of sequence. For instance, Change Order 1 might be submitted for approval in January and take 3 months to obtain permit, meanwhile work on site continues and numerous other areas are changing that overlap the area submitted in CO#1 and may obtain approval in the field. Entire sheets may be changing as departments are reshuffled at the interiors level, while in the field, materially altering changes are approved concerning fabrication and installation clarifications. The model now has information spanning different approval timeframes. One, which sequentually hasn't been approved, and others that have approval. The CO#1 changes may not be seen in any of the subsequent change orders until approved, how are those Change Orders hidden both in the sheet and in the sheet description? How can we minimize duplicating sheets and views to handle the gymnastics that appear in the issue description bar?

    To arrive at an answer you probably need to story board a few examples of actual things that you've encountered before and mock them up. Assuming at some level a sheet is issued for review and approval that sheet can't really be used again until it has been approved. That implies that you need enlarged plans and discreet sheets to show as much or as little work is proposed for approval. This way you can use masking regions in other views on sheets that certain areas are pending approval. If rooms are in the equation you can use a parameter and color fill to help differentiate between "status". The complexity of overlapping status will heavily influence how many tricks you'll need to use to keep track of and visibly differentiate the work at hand.

    I'd suggest that you create a simple family that contains a filled region to 'hatch' the area of influence of any pending CO's. It might be a graphic only family or a solid piece of geometry with a cut pattern that will facilitate hatching in plan and section.
    You can then place the family in the project where it's needed. You could add a variety of parameters (status, associated CO, submission date, approval date etc) to the family so when you schedule them you can quickly get a report of all pending, approved and contemplated changes.
    As for the issue of work around unapproved changes being able to move forward, the hatch would serve as a visual reminder that any changes to the model occurring in areas still not approved need to consider how they impact those unapproved changes.
