Yes. Publish a new version from Revit and BidLight diffs it against the last one, element by element. You see exactly what moved, what was added, what was deleted, and who touched it.

Proof is a record tied to the element, not a note in someone's inbox.

Yes. The project record stays with the project, not the person. Every export from Revit or Navisworks is versioned and compared element by element.

The 6am digest lands in every owner's inbox before the day starts. It lists what you own: your open issues, the ones pinned to your elements, and what moved on the model since yesterday.

Yes. Every export BidLight publishes from Revit or Navisworks is versioned, and each new version is diffed against the last element by element.

Your sub never has to leave Navisworks. BidLight runs inside it, so he publishes straight from the federated model and works his issues right there. Here is the loop: 1.

An issue pins to the element it concerns inside the model, not to a PDF or a chat thread. Click it and you land on the exact duct, pipe or beam that caused the problem. Here is the flow: 1.

The 6am digest is your daily list of what you own. It goes to every owner on the project with their issues in it. Not the whole team's pile. Yours. Each issue is pinned to the element it concerns.

No. Closing an issue in BidLight needs a person and a model commit, so your MEP sub will log in. That is the point of it. Here is what closing looks like.

Every morning at 6am, everyone who owns an issue gets a short digest of what they own.
