The Linarc platform allows for a collaborative review process between the general contractor (GC) and subcontractors. After you submit your initial estimate, the GC reviews the details to ensure they align with the project's scope and budget. If the GC requires adjustments—such as price updates, quantity changes, or scope clarifications—they will send the estimate back to you for a revision. When a revision is requested, you can
Update your original bid by adjusting the cost data of existing line items or adding new line items as required
Re-upload a new estimate file to completely replace your previous submission
Add supporting documents, such as photos, or notes to address any specific concerns raised by the GC.
This iterative process ensures that both parties are in full agreement before the final approval.
Once revised, you can resubmit the estimate directly through the platform. The GC will then perform a final review of your updated bid to move forward with the approval process.
