CONSTRUCTION INTELLIGENCE / REVISION COMPARISON
Send us two plan or schedule revisions. Mirage flags exactly what changed and where in 48 hours, so your team can assess the schedule impact before it becomes a delay claim.
Running at OCBM and a US rail contractor.
THE REALITY
Identifying what changed between one plan revision and the next used to mean a side-by-side visual comparison. It introduced errors and regularly missed delta items on complex sections, and by the time a change was noticed, its schedule impact was already someone's problem.
WHAT MIRAGE DOES
01
On every new revision, Mirage compares it against the prior version and generates a structured delta report, no manual side-by-side comparison required. Runs on plan sets, schedules, and specification documents alike.
02
Every flagged change points to the specific sheet, clause, or quantity that differs, with both versions referenced. Nothing is summarized into a vague "revised" note that leaves your team re-checking anyway.
03
The structured delta drops into the scheduling and document workflow you already run, connecting to Procore, Autodesk, and the systems already in place. Your team applies the impact assessment; Mirage removes the manual comparison step.
THE OUTPUT
| Item | Rev A | Rev B | Change Type | Location |
|---|---|---|---|---|
| Turnout geometry, No. 10 crossover↳ Reduced radius on this crossover falls outside the tolerance stated in the applicable spec, flagged for review before it's applied. | Standard radius | Reduced radius | Geometry deviation | Sheet C-14 |
| Work zone WZ-08 | Not present | Added | New scope | Sheet C-22 |
| Clearance requirement, Section 6.1↳ Clearance value increased by 25 mm between revisions, flagged so the schedule and procurement impact can be assessed before proceeding. | 150 mm | 175 mm | Value change | Sheet 21, profile |
| Rebar cover, Section 03 20 00 | No change | No change | None | Sheet S-108 |

Every flagged inconsistency reaches an engineer before it's acted on
Send us two revisions from an active project, and we'll show you exactly what the delta report flags.
FAQ
No. Mirage identifies exactly what changed between two plan or schedule revisions and where. Your scheduling team still runs the actual critical-path or float analysis; Mirage removes the manual comparison step that comes before it.
Any geometry, quantity, work zone, or clause that differs between the two versions you send in. Every flag names exactly what changed and points to both source locations, so nothing has to be found by eye.
Yes. Mirage doesn't replace your scheduling tool. It reads the plan and document revisions that feed into it and returns a structured delta your team applies inside the system you already use.
Yes. Once connected, it compares each new revision against the prior one automatically and returns the delta, so nobody has to manually trigger a comparison every time a revision lands.
Specification review checks a spec against a plan. This compares two versions of the same document set against each other, to isolate exactly what changed between them.
Yes. Mirage flags what changed; your team decides what it means for the schedule. Nothing is escalated to a delay claim or a schedule revision automatically.
Under four weeks on average to a production deployment, following the same audit-then-pilot approach as our other construction agents: indexing and setup first, then a parallel pilot on one active project's revision cycle.
Pricing starts with a fixed-price pilot run on two real revisions from an active project, so you see the delta output before committing to anything larger. After that, it moves to an annual subscription priced by volume, quoted in your first conversation with us.
