Addendum & Drawing Change Detection
Catch scope changes before they become lost margin.
Continuously compares revised drawings, specifications, and addenda against prior versions and flags material scope changes.
The operational problem
Why this system exists.
Project teams often know that a revision arrived but cannot quickly determine what changed, whether the change affects fireproofing, or whether the estimate and proposal need to be updated. Manual sheet-by-sheet comparison is slow, and subtle thickness, assembly, product, area, or schedule changes can be missed entirely.
What you are buying
A functioning operating system—not a prompt, chatbot, or generic workflow.
The system versions every project document, compares each revision against the previously reviewed set, and isolates changes with potential fireproofing impact. It produces a review queue that explains the old condition, the new condition, the affected location, and the likely estimating or commercial consequence.
BUILT FOR
Contractors repeatedly receiving revised drawings and addenda after takeoff or proposal work has already begun.
How it works
From raw project information to controlled action.
The exact integration changes by contractor. The operating sequence and accountability do not.
Compare
Detect textual, tabular, schedule, detail, and sheet-level changes between versions.
Filter for trade impact
Prioritize changes involving fire ratings, assemblies, thickness, materials, areas, access, and sequence.
Drive action
Route pricing impacts to estimating and post-award commercial impacts to project management.

Business outcome
Reduced missed scope, better pricing accuracy, and stronger protection against uncompensated additional work.
Performance is measured
This implementation is managed against operating indicators—not whether the automation merely runs.

Commercial structure
$20,000 implementation. $3,500/mo ongoing management.
Implementation covers discovery, system architecture, configuration, integration, testing, controlled rollout, and team adoption for the agreed scope. Ongoing management covers monitoring, exception handling, optimization, reporting, and operational support.
$10,000 operations assessment
Find the most expensive gap first.
We analyze your current operation, quantify revenue leakage and administrative drag, then build a custom implementation roadmap. The assessment fee may be credited toward a larger implementation.
