Estimation Workspace
Darwin’s estimation workspace is the revision-level screen for inspecting, defending, and moving one estimation toward a decision.
In the request-to-baseline workflow, it carries:
estimate → review → approve
Open it from the project’s Estimations tab. Use Estimation Details for line-level work such as adding modules, editing quantities, and changing direct costs; use the workspace to review the revision as a whole.
Read the Revision State
Section titled “Read the Revision State”The header shows the current approval state for this revision:
| State | What it means |
|---|---|
| Not requested | The revision has not entered the approval path yet. |
| Pending | An approval decision is still required. |
| Rejected | The decision is recorded; use a request or later revision to address the outcome. |
| Approved - active baseline | This is the revision Cost Control tracks. |
| Approved - superseded | This revision was approved, but a later revision is now the active baseline. |
An approved active revision is not the place to make a quick line correction. Its line editor is read-only; work in a later revision when the estimate needs to change.
Use the Workspace Tabs
Section titled “Use the Workspace Tabs”| Tab | Use it to |
|---|---|
| Summary | Review the cost roll-up, sections, margins, grouping, and scenarios. |
| Reports | Generate or access estimation reports and exports. |
| Proposal | Build the client-facing proposal from this revision. |
| Estimate Review | Resolve review findings before a decision. |
| Bid Leveling | Manage bid packages, received proposals, clarifications, and leveling decisions. |
| Requests | View or raise work requests tied to this estimation. |
| Audit | See who changed the estimation and when. |
| Comparison | Compare this revision with another revision side by side. |
| Activity | Review the revision’s activity history. |
Badges on Estimate Review and Bid Leveling indicate open items that need attention.
Move a Revision Toward a Decision
Section titled “Move a Revision Toward a Decision”- Review the Summary and open Estimation Details when line-level changes are needed.
- Resolve findings in Estimate Review.
- Use Requests to create a clarification, change, price refresh, alternate, or approval request with the estimation already in context.
- Use Comparison to explain meaningful differences from another revision.
- Return to the project summary for the approval decision.
The workspace helps prepare an approval, but it does not own the final decision. Requesting and recording approval happen through the project-level workflow.
Best Practices
Section titled “Best Practices”- Review a revision in the workspace before treating it as ready for approval.
- Raise a work request instead of relying on an informal side conversation.
- Use Approved - superseded as history, not as the current cost-control baseline.
- Keep reports, proposals, bid decisions, and review findings tied to the revision they describe.
