Built for construction document review
NexScan, NexCompare, RFIs, and NexDocs in one platform.
Clash Nexus AI combines drawing-set review, revision comparison, evidence markups, issue tracking, RFI wording, CSV/PDF exports, and NexDocs project context without exposing customer data to public pages.

Multi-Discipline Clash Detection
Reads architectural, structural, and MEP sheets together and pinpoints where systems physically collide.

Cross-Sheet Consistency
Catches contradictions, wrong references, and mismatched dimensions across the entire drawing set.

Missing Detail & Spec Checks
Flags incomplete notes, absent details, and specification gaps before they reach the field.

Instant RFI Drafting
Turns every finding into a clear explanation and ready-to-send RFI wording in one click.

Evidence & Markups
Pinpoints the issue location with markups, affected sheets, and evidence context you can review.

Shareable Reports
Export clean, professional reports your team, clients, and stakeholders can act on immediately.
Core product areas
From full scan to revision intelligence and RFI handoff.
The product is organized around how construction teams actually review: scan the set, compare revisions, verify evidence, assign actions, and send clear RFIs when needed.
NexScan full scan
Scan drawing sets for coordination issues, missing information, document-health gaps, schedules, references, code/fire/ADA foundations, and dimensional review items.
Learn moreNexCompare revisions
Compare drawing revisions with sheet matching, match percentage, added/removed sheets, discipline summaries, and narrative change review.
Learn moreIssue workflow and exports
Track evidence, assignments, comments, verdicts, issue status, CSV issue tables, PDF reports, and provider-ready action payloads.
Learn moreRFI and NexDocs
Draft RFIs, identify duplicate RFI groups, detect spec-section anchors, summarize submittal requirements, and prepare document-review handoffs.
Learn moreIncluded review coverage
More than clash detection.
High-risk new categories use evidence gates and needs-review status first. The system adds coverage without suppressing existing full-scan findings.
Built for the whole project team
Solutions for contractors, consultants, owners, and trades.
Each stakeholder sees review risk through a different lens. Clash Nexus AI keeps the same evidence trail while supporting the owner, consultant, contractor, and trade workflow.
For General Contractors
Catch coordination issues before they become RFIs, delays, and rework.
Clash Nexus AI reviews full drawing packages across architectural, structural, and trade drawings to surface conflicts, missing information, and contradictions before they hit the field.
For Design Consultants
Improve drawing quality before your client, contractor, or site team finds the issue.
Clash Nexus AI acts like an AI quality-control layer for design teams, checking drawings for coordination gaps, missing details, wrong references, and inconsistencies across sheets.
For Owners & Developers
See design risks before they become budget risks.
Clash Nexus AI helps owners and developers understand where drawing conflicts, missing information, and coordination gaps could create RFIs, change orders, delays, and rework.
For Subcontractors
Protect your scope before you price it, build it, or get blamed for it.
Clash Nexus AI helps subcontractors check their trade drawings against architectural and structural intent, identifying conflicts, missing information, and scope risks before work starts.

Discipline coverage
Built for 13 construction disciplines
Clash Nexus AI reviews full drawing sets across design and trade scopes. Architectural and structural drawings form the base set, while every uploaded discipline is checked for missing information, coordination risk, revision impact, and cross-trade conflicts.
Turn project documents into review-ready actions.
Scan, compare, review, assign, export, and draft RFIs from one construction AI workspace.
