The Evaluation Methodology

An Unbroken Chain from Raw Source to Governed Decision

PEIS processes complex project documentation through a structured, 8-stage evaluation pipeline. Every conclusion is cryptographically anchored to verbatim source evidence, ensuring rigorous traceability and evidence-grounded analytical rigor.

The 8 Evaluation Stages

Deterministic Processing with Full Provenance

Trace how unstructured project archives progress into court-ready evaluation dossiers.

STAGE 01
Ingestion Layer

Source Ingestion & Content Normalization

Heterogeneous project records—contracts, specifications, schedule baselines (XER/XML), RFIs, daily logs, submittals, meeting minutes, and change requests—are ingested and cataloged with SHA-256 cryptographic fingerprints to verify evidence immutability.

Technical Specifications SHA-256 REGISTRY
  • Ingested Formats: PDF, P6 XER/XML, MSG/EML, DOCX, XLSX
  • Normalization: OCR, layout preservation, coordinate bounding
  • Integrity: Permanent immutable document hash assigned
STAGE 02
Rules Layer

Requirement Identification

Extracts and structures contractual covenants: strict notice timing requirements (e.g. "written notice within 10 calendar days"), submittal review turnaround windows, baseline schedule update intervals, differing site conditions protocols, and milestone liquidated damages provisions.

Technical Specifications CLAUSE_PARSER
  • Extraction: Notice triggers, milestone dates, turnarounds
  • Classification: Mandatory covenants vs procedural guidelines
  • Schema: Normalized clause graph with contract coordinates
STAGE 03
Factual Layer

Evidence Extraction & Mapping

Factual occurrences are isolated with exact temporal stamps and author/recipient metadata. PEIS builds an integrated event graph connecting RFI submissions, architect responses, field directives, inspector logs, weather records, and progress photo timestamps.

Technical Specifications EVENT_GRAPH
  • Temporal Graph: Multi-party chronological ordering
  • Cross-Referencing: RFI-to-Submittal-to-Change linkages
  • Provenance: Verbatim text excerpts with byte/page bounds
STAGE 04
Analytical Layer

Evaluation & Compliance Synthesis

Evaluates factual execution records against established contractual covenants. The engine checks timeline adherence (was notice timely submitted?), deliverable completeness (were mandatory attachments provided?), and schedule impact correlation (did the event affect critical path activities?).

Technical Specifications EVAL_ENGINE
  • Compliance Checks: Notice timeliness & procedural validity
  • CPM Correlation: As-planned vs as-built critical path alignment
  • Coverage: Requirement coverage matrices with full audit trails
STAGE 05
Discrepancy Layer

Contradiction & Variance Detection

Conflicting assertions across documents are flagged immediately. For example, if a contractor claim asserts site access was barred on Day 45, but contemporaneous daily inspection logs indicate active steel erection by 12 workers on that exact date, PEIS isolates the conflict with dual-source citations.

Technical Specifications CONTRADICTION_DETECTOR
  • Cross-Matching: Multi-stakeholder assertion comparison
  • Dual Citation: Supporting vs counter-evidence alignment
  • Confidence: Factual disparity scoring and human escalation
STAGE 06
Synthesis Layer

Evidence-Supported Finding Generation

Discrete evaluations, CPM schedule variances, and verified facts are synthesized into structured, defensible findings. Every finding includes unbroken provenance breadcrumbs linking each assertion directly to underlying source files and line coordinates.

Technical Specifications DOSSIER_GEN
  • Dossier Assembly: Fact-based narrative synthesis
  • Citation Breadcrumbs: Document ID, Page, Paragraph anchors
  • Repeatability: Deterministic reproducibility across test runs
STAGE 07
Risk Layer

Risk & Exposure Analysis

Findings are mapped into programmatic and commercial exposure matrices: critical path delay exposure (calendar days), cumulative cost claim liabilities, constructive change vulnerability, and potential liquidated damage assessments.

Technical Specifications EXPOSURE_SCORECARD
  • Schedule Exposure: Critical path float consumption deltas
  • Notice Liability: Forfeiture risk quantification
  • Dispute Matrix: Claim strength and defense posture scoring
STAGE 08
GOVERNED AUTHORITY

Human Professional Review & Decision

The analytical process terminates in human hands. Project managers, legal counsel, and executive decision-makers review the synthesized evidence dossier, adjust weightings if warranted, and exercise authoritative judgment. PEIS strictly serves as an analytical co-pilot—never an autonomous decision-maker.

Technical Specifications HUMAN_GATE_AUTHORITY
  • Authorization Gate: Mandatory human sign-off on determinations
  • Audit Log: Reviewer identity, comments, and decision timestamp
  • Export Formats: Audit packages, legal exhibits, executive briefs
Dynamic Provenance

Dependency-Aware Revalidation: Integrity in Motion

Complex projects are dynamic. New documents arrive constantly: revised CPM schedules are submitted, dispute notices are issued, or historical records are clarified.

In traditional static analysis, adding new documents requires restarting the entire review from scratch. In PEIS, the evaluation graph is dependency-aware:

Automated Revalidation Cascade:

When an upstream evidence item is updated, added, or revised, PEIS flags all downstream evaluations, contradictions, findings, and risk scores as "Pending Revalidation" until the updated evidence is propagated through the rule chain.
