Firmus
Firmus is a preconstruction software product that applies AI to PDF construction drawing sets for early risk detection, issue tracking, and optional set-to-set comparison through Firmus AI-REVIEW and AI-MATCH.
Firmus targets general contractors, architects, developers, and owners who want structured checks before field work. Users upload drawing packages; the service scans sheets to flag incomplete scope, missing references, coordination gaps, and similar document-health problems.
The vendor splits capabilities between Firmus AI-REVIEW for issue detection and reporting, and Firmus AI-MATCH for comparing full drawing sets across phases when you choose Premium-level options. The public pricing page lists yearly analysis allowances rather than public dollar amounts, with Basic at five analyses per year, Advanced at twenty, Premium at one hundred, and Enterprise as custom (Firmus, 2026).
Architectural scope checks cover doors, windows, storefront, partitions, and horizontal assemblies, while MEP checks include fixtures and discipline tie-ins. Shared checks also look for index mismatches, missing referenced sheets, missing scales, and grid issues.
Collaboration features include assignments, exports, and enterprise controls such as SSO on higher tiers. The workflow is iterative: teams can reload later design phases to compare open and resolved issues as documents evolve.

Frequently asked questions
What file type does Firmus analyze?
- Marketing pages describe uploading PDF construction drawing sets. For native CAD or BIM exports, teams typically print or publish controlled PDFs first, then run Firmus on those packages.
How much does Firmus cost?
- The public site does not show currency prices online. It lists Basic, Advanced, Premium, and Enterprise plans with different yearly analysis limits and directs visitors to contact forms. Confirm current fees and tax with Firmus before purchasing.
What is Firmus AI-MATCH?
- AI-MATCH is the set-to-set comparison feature that looks across full packages to spot variances between phases. The vendor states it is bundled with Premium and Enterprise plans rather than sold as a standalone add-on in the same wording.
Does Firmus remove human reviewers?
- Firmus positions itself as automation for repetitive checks while reviewers handle judgment calls and final approvals. Expect a hybrid process rather than a full replacement for engineering sign-off.
Can Firmus run again after design changes?
- Yes. The FAQ on the vendor site explains that teams can upload new versions as the design moves through percentages and phases, tracking resolved items and new findings.
Who is Firmus built for?
- The homepage names general contractors, construction managers, architects, developers, and owners involved in preconstruction. Use cases include risk reduction before bid and execution, plus clearer communication around drawing gaps.
