How OCBM Automated Its Takeoffs and Bids with Mirage
OCBM's estimating teams used to read drawings and price tenders by hand. Mirage deployed agents that extract quantities from their plans, prepare bid pricing, and check consistency across drawing revisions.
About OCBM
OCBM (Omnium de Construction et de Bâtiment du Maghreb) is a Moroccan construction company founded in 1977 and based in Casablanca. It delivers turnkey and separate-lot projects across Morocco, working all trades from structural concrete to finishing.
Before every bid, OCBM's estimating teams have to read the drawings, measure quantities, and price the work. During busy tender periods this is slow, repetitive, and hard to scale, and a single missed quantity or an outdated drawing revision can distort a whole bid.
Where it started
Mirage began with the workflow that consumes the most estimating time: quantity takeoff. Mirage deployed its Construction Intelligence agent on OCBM's own drawings, across multiple plan types including formwork and structural drawings, extracting quantities automatically and linking every figure back to its source on the drawing.
Mirage engineers worked on OCBM's real projects and real documents, not a generic template. Every extracted quantity stays traceable, so an engineer can check it against the drawing before it goes into a bid.
How the agents work
Quantity takeoff
The agent reads architectural, structural and formwork drawings and extracts the quantities automatically. Each figure is linked back to the exact location on the drawing it came from, so nothing is a black box.
Bid pricing and quantity schedules
On top of the takeoff, Mirage added a pricing layer that turns extracted quantities into structured quantity schedules (bordereaux quantitatifs) and helps OCBM respond to tenders faster, with the measured quantities feeding directly into the bid.
Drawing and document consistency
A dedicated agent checks consistency across drawing revisions and between the tender documents themselves, comparing versions of plans, DCE and CCTP to surface discrepancies before they reach a submitted bid.
Human in the loop
The agents do the measuring and the cross-checking. OCBM's engineers keep the judgment. Every quantity is reviewable against its source on the drawing, and every flagged inconsistency reaches an engineer before submission.
What changed
OCBM's estimators no longer measure quantities by hand or manually diff drawing revisions. The repetitive part of the takeoff and the consistency checks now run automatically, with engineers validating rather than measuring. What started as a single takeoff workflow has grown into three production agents, making Mirage OCBM's AI partner for construction.

“We started with one part of the estimating work, and Mirage kept building. Takeoffs, pricing, drawing checks: each time, they delivered something our engineers actually use on live tenders. They have become our AI partner for construction.”
