As-built Reconciler
As-built Reconciler is the closeout-prep engine that turns as-built markups into a structured redline log. It compares the construction-set notes with the field-marked as-built notes and records each difference with its delta type, severity, side-by-side values, location and rationale, then saves the log for the closeout package.
What is the As-built Reconciler?
As-built Reconciler is the closeout-prep engine that turns the field-marked as-built drawings into a structured redline log. For each detected difference between the construction-set notes and the as-built markup, the engine writes a structured record: delta type (dimension / equipment / route / elevation / quantity / material / other), severity (critical / major / minor / info), side-by-side spec ↔ as-built values, location reference, and a one-line rationale.
Each delta is saved as an as-built redline for downstream consumption by Closeout Builder. The structured log replaces the typical "we marked up the prints, here's a stack" handoff — the owner gets searchable, indexed deltas instead.
v1 ships text-only: paste or extract the construction-set notes and the as-built notes side-by-side. v2 will add drawing-image diff via a CV pipeline that detects bbox-level redline markup on the actual sheets.
When should I use the As-built Reconciler?
Use As-built Reconciler during closeout prep to turn redline drawings into the log for the owner package, after a major design change to compare what was built with what was specified, before substantial completion to document field deviations, or later when maintenance finds a deviation and you need the field history.
- Closeout prep — turn the redline drawings into the structured log for the owner package.
- After a major design change — reconcile what was built vs what was specified for the change order audit.
- Pre-substantial-completion sweep — identify and document all field deviations before the architect's punch walk.
- Operating year — building maintenance discovers a deviation and you need the field history.
Reconciled redlines attach as a required deliverable in Closeout Builder. Run the reconciler first, then the builder pulls the deltas into the owner-ready package.
What do I upload to the As-built Reconciler?
Two text inputs: the construction-set notes (what was specified) and the field-marked as-built notes (what was actually built). Both can be pasted or extracted from PDF. Best results when the inputs are scoped to a discipline and area (e.g., "Level 3 Mechanical") rather than the entire drawing set.
Optional: the change order log (anchors changes to formally approved COs), the original specification (deeper context for deviation severity), and the discipline tag (mechanical / electrical / plumbing / structural / architectural).
How do I run the As-built Reconciler?
To run As-built Reconciler, open it, paste or upload the construction-set notes and the as-built notes, tag the discipline and area, run the reconcile, walk the redline log, verify the change-order-backed deltas and persist the log for closeout.
Open the engine
Sidebar → Engines → As-built Reconciler.
Paste or upload construction-set notes
The originally-specified state of the work. PDF or pasted text.
Paste or upload as-built notes
The actually-built state. Field markups, RFI-driven changes, CO-driven changes, and unrecorded deviations all surface here.
Tag discipline + area
Optional but improves accuracy. Tells the engine the domain so it doesn't misclassify deltas.
Run reconcile
20–40 seconds.
Walk the redline log
Each delta has type, severity, side-by-side values, location, rationale. Click any delta to see source quotes.
Verify CO-backed deltas
Engine flags deltas that match an approved CO — those are authorized. Unmatched deltas are unauthorized field deviations worth investigating before owner handover.
Persist for closeout
Click Persist Redlines to save each delta as an as-built redline for Closeout Builder.
How do I read the As-built Reconciler results?
The result is a redline log in which every delta carries a type badge, a severity badge and a change-order match indicator, with a rollup by discipline and the persisted deltas for the closeout package.
Numbered deltas with type, severity, side-by-side spec ↔ as-built values, location, and rationale.
Dimension / equipment / route / elevation / quantity / material / other. Color-coded for quick scan.
Critical / major / minor / info. Critical deltas typically need owner sign-off before closeout.
Green check when the delta is backed by an approved CO. Amber question when unmatched — potential unauthorized deviation.
Count of deltas by discipline (mechanical / electrical / plumbing / structural / architectural). Quick view of where the deviations cluster.
Confirmation that the redlines saved as as-built redlines for downstream consumption by Closeout Builder.
