Chat with Archer
Archer keeps every answer tied to the exact sheet it came from, so your team can verify the source instead of chasing context.
The stair detail is shown on sheet A-2.00.
Plan Check
Inspect automated findings with the code context your team needs to make the next call.
Takeoff
AI-assisted framing takeoffs, checked by a human reviewer before they reach you.
RFIs
Draft questions from the set and keep each RFI linked to its source sheet.
Team Sharing
Keep source-linked plan answers in one project record so every project role can verify the same context.
Field Photos
Organize field photos beside the project record used for plan review.
Solutions by team
Start with the decisions your team owns. The project context stays connected underneath.
Trace plan questions to the sheet, review for code compliance, and coordinate disciplines across the plan set for potential conflicts. Give applicants a clearer way to identify missing information and code concerns before official review begins.
