From CAD to costed tender, in days, not weeks.

We build validation-driven automation that turns CAD and PDF drawings into accurate take-offs, bills of materials, and cost estimates, with a human checkpoint built in, not bypassed.

The problem this solves

Manual take-off and estimation from CAD and PDF drawings is slow, and it gets slower every time a design changes. Each round of revised drawings, as end-customer requirements evolve, means re-doing the estimate from scratch, often taking weeks per iteration, with accuracy depending entirely on how carefully someone reviewed the drawings that time.

How it works

Import CAD and PDF drawings directly into a validation environment

Automated take-off extraction, with every result reviewable by a human before it's accepted

Human verification checkpoint built into the workflow, not optional

Export directly into a bill of materials and cost estimate, ready for tender inclusion

Built for evolving drawings

Designs mature. Requirements change. This isn't a one-off extraction tool, it's built to handle multiple iterations as drawings are revised, so the take-off and estimate mature alongside the design instead of starting over each time.

Real-world result

In practice, this has reduced take-off and estimation turnaround from weeks to days, with improved accuracy, freeing senior estimators for higher-value review work instead of manual re-processing.

Case study: Manufacturing

REAL ENGAGEMENT

From hours to minutes, automated review of technical drawings.

A manufacturing client needed to validate engineering drawings and technical documents at volume, a manual process prone to error and slow to scale. We built an AI-powered document validation system integrating with SharePoint, Azure and Vault, with annotation directly on drawings to mark issues and maintain a clear audit trail.

Manual review time per document

The system also improved detection of errors and inconsistencies, and scales cleanly for large, complex drawing sets.
