Material take-offs
Piping, steel, cable and equipment counted from isometrics, layouts and schematics, discipline by discipline, issue after issue.
AI for EPC and MEP contractors: MTO and bills of materials
AI for EPC and MEP contractors reads the engineering package, isometrics, P&IDs, layouts, schematics and specifications, and returns the material take-off (MTO) and the fabrication bill of materials (BOM), discipline by discipline, each line tied to the drawing and revision it came from and checked against the specification before anything is bought. In production at John Cockerill, an industrial engineering group, with 80 to 90% less time on piping takeoff and a fabrication BOM produced ten times faster.
Where the time goes on engineering packages
EPC is the contract model, from engineering through procurement to construction; MEP is the mechanical, electrical and plumbing scope inside a building or a plant. Both work from engineering packages across disciplines, and both lose time in the same places.
Bills of materials
Fabrication and purchase lists rebuilt by hand from the drawings, then reconciled with what the specification requires.
Specifications against drawings
A material or requirement in the specification that a drawing contradicts is found late, sometimes after the order is placed.
Revisions during procurement
Engineering keeps issuing while procurement buys, and each issue has to be compared with what was already ordered.
What Mirage runs for EPC and MEP contractors
The same platform reads every discipline. Each quantity and each list line keeps the drawing and revision it came from.
Piping takeoff
Material take-offs from piping drawings and isometrics, each line tied to its drawing and revision.
Fabrication bills of materials
Bills of materials produced from the drawings and kept separate from the take-off, ready for your engineers to review.
Electrical takeoff
Devices, runs and equipment counted from electrical layouts and schematics.
Specifications and information take-off
Requirements pulled from the specifications and checked against the drawings, each conflict pointing to the clause and the sheet that disagree.
Discipline by discipline: what is counted, from which drawings, into which list
The engineering disciplines an EPC or MEP package covers, the drawings each one is read from, and what the take-off and the bill of materials hold. Piping runs in production at John Cockerill; boilermaking and structural steel are being rolled out on the same platform.
| Discipline | Read from | The MTO holds | The BOM holds |
|---|---|---|---|
| Piping | Isometrics, P&IDs, line list, piping layouts | Pipe by size and spec, fittings, flanges, valves with tags, supports, weight and paint surface | Drawing by drawing, shop welds and field welds kept apart, for the fabrication shop |
| Boilermaking and pressure parts | Fabrication drawings, plate and nozzle schedules | Plate by grade and thickness, nozzles, flanges, bolting | Per assembly, with weld lengths and heat-treatment notes as drawn |
| Structural steel | General arrangements, member schedules, connection details | Members by section and grade, plates, bolts, with lengths and weights | Per piece mark, with connection parts and surface treatment |
| Electrical | Layouts, one-lines, panel and luminaire schedules, cable schedules | Devices by type, cable by run and type, conduit, homeruns traced to their panel | Per panel or per area, as the installation is packaged |
| HVAC and plumbing | Layouts, schematics, equipment and fixture schedules | Duct and pipe by size, fittings, equipment and fixtures by tag | Per system or per zone, with insulation and supports |
Every line carries the sheet and revision it was read from; where the drawing and the schedule disagree, the line comes back flagged rather than resolved by assumption.
In production at John Cockerill
An industrial engineering group whose estimating and method teams read piping, boilermaking and structural steel drawings for every quote.
80-90%
Less time on piping takeoff
÷10
Time to a fabrication bill of materials
- Before
- The estimating and method teams took quantities off 2D drawings by hand for every quote.
- Deployment
- A platform that reads isometric drawings and produces separate MTO and BOM outputs. Piping runs in production; boilermaking and structural steel are being rolled out on the same platform.
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.
Questions from EPC and MEP contractors
No. EPC is a contract model, from engineering through procurement to construction; MEP is the mechanical, electrical and plumbing scope inside a building or a plant. Mirage does the same work on both: quantities and bills of materials from engineering drawings, checked against the specifications.
At John Cockerill: 80 to 90% less time on piping takeoff, and a fabrication bill of materials produced ten times faster. Mirage publishes no accuracy percentage.
MTO software inside a 3D plant design tool produces the take-off from the model, and is the right answer when a model exists and is current. An AI takeoff layer reads the 2D deliverables, isometrics, P&IDs, layouts, as issued, with no model required first, and feeds the estimating or procurement system you already use. At John Cockerill, the fabrication BOM used to require rebuilding the 3D model first; that step is gone.
No. It returns quantities with their attributes (line number, size, spec, rating, tag, sheet) in the import format of your estimating or procurement system. Your catalogue, your rates and your supplier quotes stay where they are.
A proof of concept on your own documents one week after the first meeting, then the first workflow in production in 4 to 6 weeks. The pilot is fixed-price and you can stop after it.
Project management and document control platforms such as Procore and Autodesk Construction Cloud, estimating spreadsheets, ERP and accounting systems such as SAP, Oracle and Sage, and scheduling software. Where a documented interface exists, Mirage connects to it; where none exists, our engineers build the connector during deployment. Nothing is migrated.
