Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →Clash Nexus AI is designed to review construction drawing sets as connected documents rather than isolated PDF pages. Founder and CEO Akam Pachachi says it identifies relationships across disciplines, flags potential coordination and information issues, and gives reviewers sheet locations and drawing evidence to check. It is intended to support human review—not to certify that a set is complete or clash-free.

Why review a drawing set as a connected system?
Construction teams use issued PDF drawing sets to price work, buy it out, and build it. A coordination issue may only become visible when two sheets are read together—for example, when mechanical ductwork shown on one page conflicts with a structural beam shown on another. Other risks include contradictory information between sheets, absent schedule details, work assigned “by others,” and revision changes that are hard to spot by eye.
Pachachi frames a 200-sheet set as having just under 20,000 possible sheet-to-sheet pairs. That is a way of describing the number of potential relationships, not a measured industry statistic. His point is that reviewing each page in isolation can leave cross-sheet questions undiscovered.

How does Clash Nexus AI review PDF drawings?
According to the founder, the workflow begins with a complete PDF package. The platform identifies sheets, disciplines, floors, buildings, and scope, then pairs sheets it considers relevant and checks for geometric clashes and other issues. The described input can include architectural, structural, MEP, trade, and shop drawings.
Issues it is intended to flag
- Potential clashes between elements represented on different sheets.
- Contradictions from one sheet to another.
- Missing information, including schedule details.
- Conflicts between drawings and specifications.
- Constructability concerns and code-related signals.
- Scope and handoff notes, including work assigned to others.
A flagged item is presented with a sheet and location, drawing evidence, severity, likely impact, and a recommended next step. Reviewers can accept or reject findings. This evidence-and-review step matters: an automated flag is a prompt to verify an issue in context, not proof that the drawing is wrong.

What happens to findings, handoffs, and revisions?
Review and RFIs
Pachachi says reviewed findings can be sent as requests for information to Procore and Autodesk. The article reports these integrations as live; it does not establish the scope of every integration or independently verify the workflow.
Scope Ledger
The Scope Ledger is described as extracting handoff notes and organizing obligations, recipients, supporting drawing references, and Procore bid-package coverage. This extends the product’s stated purpose beyond detecting clashes to helping teams track who owns work and what information supports that assignment.

Revision comparisons
When a new drawing issue arrives, the revision workflow compares it with the prior issue and identifies findings that are changed, resolved, or new. It can also identify affected RFIs or scope items, according to the founder. That can help teams focus their review on changes rather than starting from scratch, but it does not remove the need to check the revised sheets.
Does it require a BIM model?
No BIM model is required, Pachachi says; the product is designed to work from PDFs, including at bid time when some trade contractors and preconstruction teams may not have a coordinated model. That makes its stated input and focus different from model-based clash detection. Drawing review looks for relationships and contradictions in issued documents, while model-based coordination checks elements represented in a model. Pachachi says, “The two work best together.”

What performance evidence is available?
The founder reports that about 80% of more than 30 interviewed industry executives identified preconstruction drawing clashes as a significant cost. This is his account of interviews; no survey methodology or independent publication is provided, so it should not be read as a representative industry survey.

Clash Nexus AI says it flagged 65 design issues and five cross-page clashes for review. Pachachi explicitly says this was one test, not an industry benchmark. The account provides no independent accuracy study or controlled comparison, and the example does not establish how the system performs on other drawing sets. As he puts it, “Your results will depend on your drawings.”

What does the company say about data security?
Pachachi says drawing processing uses AI, OCR, and document-processing services under business or API terms; customer drawings are not authorized for training general-purpose models; projects are isolated to customer workspaces; and data is encrypted in transit and at rest. These are company statements, not audited findings in the account. The company says it is working toward SOC 2 readiness and is not SOC 2 certified.
Who is it for, and what does it cost?
The Ontario-based company says it serves construction teams across North America. Intended users include GC preconstruction, VDC/BIM, estimating and coordination teams, MEP and structural engineers, and trade contractors. Pachachi says development took about eight months before launch on August 10, 2026.
As reported by the founder on September 29, 2026, paid plans start at CA$499 per month, and the first full scan is free without a credit card. These are time-sensitive company-reported terms; confirm current pricing and offer details with the company before relying on them.
