General contractors
Hundreds of drawings, a dozen quotes per trade, revisions after pricing.
In production at OCBM, a general contractor pricing its bids from its own drawings.
AI construction software for contractors
Quantities, scope gaps and revisions from your drawings, specifications and bids, each tied to the sheet or clause it came from and checked by your team before it is used.
A project lives in thousands of pages nobody reads together.
Mirage Metrics builds and operates AI agents for general contractors, infrastructure contractors and EPC teams. Drawings, specifications, bills of quantities, subcontractor quotes and revisions each hold part of the project, and a missed quantity, a superseded sheet or an exclusion found late can distort a bid or a budget. Mirage reads them together and keeps every quantity, gap and change tied to its source: that is what we mean by project intelligence. Most teams start with takeoff, shown below.

In production at OCBM and John Cockerill
A Moroccan general contractor pricing bids from its own drawings, and an industrial engineering group measuring piping, boilermaking and structural steel. Construction is the largest group among Mirage's named clients: seven of the thirteen companies named on this site are contractors or engineering groups.

OCBM
“Mirage has helped us make our preconstruction workflows faster and more structured while keeping our teams in control of the final output. The platform is becoming a useful operational layer for how we review quantities, documents and project information.”
- Before
- Before every bid, OCBM's estimators read the drawings, measured quantities and priced the work by hand.
- Deployment
- Quantity takeoff first, on OCBM's own formwork and structural drawings. Then bid pricing into quantity schedules, then a consistency check across drawing revisions, DCE and CCTP.
- Now
- Estimators validate instead of measuring. Every quantity is reviewable against its source, and nothing reaches a bid without an engineer signing it off.
Also in production at
Every result can be checked against its source.
A quantity your team cannot verify is a quantity nobody will use. Each result Mirage returns carries the reference it came from, and your estimators and engineers review it against the original before it reaches a bid, a cost system or a project workflow.
- Quantity
- The drawing, sheet, element and revision it was measured on.
- Conflict
- The specification clause and the drawing that disagree.
- Revision
- The two sets compared, and each element added, removed or modified.
- Bid line
- The quotation line and the scope item it is compared with.
- Sign-off
- The person who validated it before it was used.
Works with any existing stack
Connects to project management and document control platforms, drawing and specification repositories, estimating spreadsheets and takeoff files, ERP and accounting systems, scheduling software and field reporting applications. No migration. No replacement.
Where a documented interface exists, Mirage connects to it. Where none exists, our engineers build the connector during deployment.
How a deployment runs
The same five steps for every deployment, in every sector.
Timeline4 to 6 weeks to a production deployment, running on your own documents from day one rather than a demo file.
Observe
Engineers spend time with operational teams before writing anything, to see how work is actually done.
You provideTime with your estimators and project teams.
Map
Workflows, exceptions, data sources, manual validations and escalation points get identified with your team.
You provideYour bid workflow, measurement rules, trade and cost-code structure, document conventions, exceptions and the checks done by hand.
Build
Systems get designed around the constraints observed on site, not an idealized process diagram.
You provideYour own plan sets and project documents, from day one.
Run
The system runs in production with human supervision and feedback loops from day one.
You provideEngineers to validate quantities before they reach a bid.
Expand
Once a workflow is trusted, the same engineering team moves to the next one.
You provideThe next workflow you want to hand over.
Security and governance
Access permissions, validation workflows and audit logs remain fully controlled by your organization. Signed NDA on request.
Deploy anywhere.
Cloud, private cloud, your own cloud account, sovereign cloud, on-premise, or edge and offline environments.
Control every action.
Role-based access, human approval flows and configurable autonomy for each workflow.
Prove what happened.
Full audit history, with every agent action traceable to the input and the rule that produced it.
Start with one workflow. Expand from there.
Most teams start with takeoff, estimating or tender review. Once Mirage knows your drawings, specifications and measurement rules, the same project record serves revisions, RFIs, changes and commercial controls.
Preconstruction
Revisions and project documents
Changes and commercial controls
Built for three kinds of contractor
The workflows are the same platform. What changes is where each team loses time.
Heavy civil and infrastructure
Drawing sets that keep changing, and changes to justify against the contract.
Clients include Flatiron Dragados and Green Infrastructure Partners.
EPC and MEP contractors
Take-offs and bills of materials from engineering packages, before anything is bought.
In production at John Cockerill: 80 to 90% less time on piping takeoff.
Frequently asked questions
Software that reads construction documents (drawings, specifications, bills of quantities, quotations, RFIs, contracts) and does the work a team would otherwise do by hand: quantity takeoff, tender review, bid leveling, revision comparison, change control. Mirage runs those workflows inside the systems you already use, and every result keeps a reference to the document it came from.
A chatbot answers when you ask it something. Basic automation runs the same fixed step every time a trigger fires. An AI agent reads documents that differ in format and content, checks them against the rest of the project on its own, and decides what to flag, with a human in the loop before anything reaches a bid, a report or a payment.
General contractors, heavy civil and infrastructure contractors, and EPC and MEP contractors: the estimating, engineering, procurement, commercial and project controls teams working on document-heavy projects. Construction clients include OCBM, John Cockerill, Flatiron Dragados, Demathieu Bard Construction and Green Infrastructure Partners.
Yes. Mirage detects scale from plan metadata, title blocks and drawing references. Teams can also override scale assumptions manually if needed.
Yes. Once quantities are extracted and validated, Mirage can structure the output for estimating workflows. Teams can connect quantities to unit rates, material requirements and internal pricing rules to produce estimates and cost calculations without re-entering values.
No. Mirage reads from and writes into the systems and spreadsheet formats you already use.
Yes. Mirage reads specifications, client briefs and applicable standards and checks project documents against them. It flags discrepancies, missing items and potential non-compliance for your teams to review.
Preconstruction: takeoff and estimating, tender review, subcontractor bid leveling. Revisions and project documents: drawing revision comparison, specification checks, RFIs and submittals, document search. Changes and commercial controls: change orders, pay applications and invoices, progress reporting. Each one is its own deployment, built around one specific document and one specific outcome.
