The work happened. The paperwork should prove it.
NXLIRA turns fragmented commercial construction records into structured, defensible project intelligence. Before a change becomes a financial dispute, we audit drawing revisions, RFIs, daily logs, and T&M tickets with AI document intelligence + deterministic mathematical verification.

FIELD DIRECTORY // COMMERCIAL AUDIT
Cross-Document Evidence Synthesis
AI does the understanding. Rules do the checking.
NXLIRA isn't designed around simply sending a PDF to an LLM and asking: “Is this change order good?”That approach is too unreliable for commercial construction. Instead, we perform source-grounded extraction paired with deterministic arithmetic reconciliation across the entire evidence chain.
HVAC Ductwork Rerouting & Structural Beam Clash
Revised drawing E2.3 Rev. 4 demonstrates 140 linear feet of 24" duct offset around transfer girder W36x230.
RFI #142 confirms elevation conflict between structural steel flange and primary supply trunk.
Architectural Field Order #19 directed immediate rerouting to maintain surgical suite ceiling clearance.
T&M Tickets #084 (16 hrs) & #086 (6 hrs) plus Daily Report (8 hrs) total 30 hrs documented vs 24 hrs claimed.
Labor hours in field records exceed claimed amount by 6 hours. Contractor under-claimed or misallocated.
Subtotal calculation reconciled, but $1,850 damper actuator cost lacks vendor invoice attachment.
Missing supplier invoice for specialized vibration isolator dampers and signed GC superintendent ticket.
No date or revision discrepancies found between RFI release and crew mobilization on site.
Construction doesn't have a document problem. It has a documentation relationship problem.
The information exists across your jobsite. But the relationship between the records is buried in silos, cloud drives, and fragmented email chains. When a $50,000 change order is submitted, general contractors and owners spend days manually trying to connect the dots.
Turning Fragmented Documents into Linked Evidence
Explains the geometrical and physical scope delta
Explains why the drawing was forced to change
Establishes written directive to perform extra work
Establishes that the physical work actually occurred
Establishes crew hours, equipment run-time, and trade headcount
Establishes wholesale unit prices and delivered freight
Documents → Folders → Spreadsheets → Emails → Manual Dispute
Event → Decision → Change → Work → Quantity → Cost → Evidence

“The work happened. The paperwork should prove it.”
Every claimed line item traced back to its verified field ticket and engineering directive.
Reconstructing the story behind every commercial modification.
The NXLIRA Evidence Chain
A commercial change order is not an isolated invoice—it is the terminus of a complex sequence of project events. NXLIRA reconstructs the complete chronological evidence chain from contract baseline to final payment.
Baseline
Contract scope, approved drawings, baseline specifications.
Change / Delta
Scope variance, revised plans, bulletins, site conditions.
Cause
RFI response, architect field order, clash detection, unforeseen soil.
Authorization
Signed directive, notice to proceed, GC correspondence.
Actual Work
Daily field logs, inspector reports, geo-tagged photos, T&M sign-ins.
Quantity
Crew labor hours, equipment duration, linear footage, unit counts.
Cost
Prevailing wage rates, vendor invoices, rental receipts, contract markup.
Schedule Impact
Critical path delay, predecessor shift, milestone adjustments.
Defensible Evidence
Submission-ready package substantiated by irrefutable proof.
AI Extracts & Understands Complex Human Context
Construction documents are unstructured and written by busy superintendents and engineers. Our document intelligence layer ingests drawings, specifications, emails, and field tickets to parse:
Rules Do the Checking. Zero Mathematical Guesswork.
Where a computer can calculate or compare something directly, NXLIRA enforces strict rules rather than asking an LLM:
If the submitted change order requests $4,658, NXLIRA doesn't ask AI whether that “looks about right.” It flags the $500 discrepancy programmatically.
Evidence, Not Hallucination
Source-Grounded Extraction
Every finding links directly to the specific sheet, paragraph, email, or daily ticket that produced it. Zero ungrounded assertions.
Deterministic Calculations
Arithmetic, quantity extensions, markup formulas, and rate lookups are calculated with exact programmatic rules—never estimated by an LLM.
Cross-Document Verification
Claims are checked across multiple independent artifacts: drawings vs RFIs vs T&M tickets vs supplier invoices.
Confidence Classification
Clear four-state taxonomy: Supported, Needs Clarification, Unsupported / Missing Evidence, and Not Evaluated.
Human Review Integration
High-value or ambiguous findings are highlighted for expert review before being delivered to the customer or GC.
No Invented Evidence
If a document doesn't establish a fact, NXLIRA reports the gap. No hallucinated bridge assumptions. No evidence = documentation gap.

From extra work to approved payment.
The NXLIRA Confidence Model
Construction documentation is too contractually and financially critical for fuzzy confidence scores. NXLIRA categorizes every claim and line item into an unambiguous four-state evidentiary model.
No evidence ≠ no change. No evidence = documentation gap.
Evidentiary Definition:
The available records substantiate the finding.
Cross-document references (drawings, RFIs, tickets, invoices) establish entitlement, quantity, and cost.
Evidentiary Definition:
Evidence exists but contains an inconsistency, ambiguity, or incomplete relationship.
E.g., daily logs report 30 crew hours while the change claim lists 24 hours, or rate differs from contract appendix.
Evidentiary Definition:
The claim exists, but sufficient supporting documentation was not found in the package.
E.g., $1,850 damper expense claimed with no supplier receipt or purchase order attachment.
Evidentiary Definition:
The available package does not contain enough baseline information to evaluate.
E.g., prime contract schedule logic missing to assess critical path impact.
Built to Work Above Existing Construction Software
NXLIRA doesn't replace the platforms your teams already use. We sit above them as the intelligence and evidence layer, extracting and cross-linking data from every repository.
The Goal Is: “Make the information inside your software understandable, connected, and traceable.”
Commercial Change Order Leakage Calculator
According to Autodesk and Procore industry benchmarks, over 35% of commercial projects experience major changes, and 28% of contractor profit is compromised by disputes, missing backup, and unrecovered field changes. Model your exposure below:

The NXLIRA Promise
Construction law and commercial relationships are founded on proof. We adhere strictly to three inviolable operating tenets:
01. We don't decide what happened. We show you what the record supports.
We do not make arbitrary contractual entitlement judgments. We highlight exactly what the written record substantiates.
02. We don't invent missing evidence. We identify the gap.
If an invoice or RFI is missing, NXLIRA flags the absence. We never fabricate connections or hallucinate documentation.
03. We don't replace construction professionals. We give them better project intelligence.
Engineers, project managers, and executives retain final decision authority. We eliminate 85% of manual paper chasing.
What Commercial Construction Leaders Say
Validated feedback from general contractors, trade subcontractors, and institutional owner reps.
NXLIRA cut through the change-order backup and showed us exactly where the documentation didn’t reconcile. Instead of spending hours going through every attachment, we had a clear list of what needed to be fixed.
The biggest value wasn’t the summary. It was being able to see why NXLIRA reached each finding and where the supporting document came from.
It caught gaps in our backup before we sent the package to the GC. That changed the way we prepare our change requests and stopped write-offs.
For the first time, we could follow a cost change back through the project record instead of just looking at the final number.
