PalydinThe Ontology Layer for Construction Finance
Foundational Software for the Construction Industry
Model every contract as a structured ontology. Both parties operate against the same model — scope, progress, forecasts, compliance, and payment derived from a single source of truth across your entire portfolio.
The Problem
The critical financial layer of every construction project remains unmodeled.
Contracts live in spreadsheets. Claims in emails. Variations in PDFs. The financial state of a construction project is scattered across tools that were never designed to connect.
Every claim period, teams rebuild the financial state from scratch — manually reconciling cumulative progress, retention, variations, and payments across disconnected documents. Errors compound. Disputes arise. Money moves slowly.
Palydin replaces this with a single, structured ontology.
The Construction Ontology
A unified model of objects, relationships, and actions that mirrors the contract itself.
Objects
The Entities
- Projects
- Contracts
- WBS Items
- Claims
- Variations
- Forecasts
- Compliance
The foundational data model mirrors the contract itself — every entity is a first-class object with defined attributes and lifecycle.
Relationships
The Connections
- Hierarchical scope trees
- Cumulative snapshots
- Counterparty access scoping
- Contract-scoped data isolation
Objects exist in relation to each other. The ontology encodes these relationships so the system can reason about the contract as a whole.
Actions
The Operations
- Define scope
- Track progress
- Forecast costs
- Assess claims
- Certify payment
- Enforce compliance
Every mutation is a defined operation against the model — auditable, reversible, and consistent with the contract state.
Platform Capabilities
From scope definition to certified payment.
Scope Definition
Model your contract as a living hierarchy
Build work breakdown structures with line items, quantities, units, and rates. The WBS is the root of the ontology — every financial operation traces back to it.
Progress Certification
Cumulative tracking with point-in-time snapshots
Each claim period captures the complete state of the contract. Progress is cumulative, not incremental — eliminating reconciliation errors and providing auditable history.
Variation Management
Track scope changes as first-class entities
Variations are not patches to a spreadsheet. They are structured objects linked to WBS items with their own approval workflows, values, and claim histories.
Financial Intelligence
Real-time visibility into contract position
Net claims, retention, cumulative progress, and contract value are derived from the model in real time. No manual calculations. No version conflicts. One source of truth.
Cost Forecasting
Probabilistic cost modeling from first principles
Decompose costs by first principles, allowances, or unit rates. Track actuals against the model. Monte Carlo simulation derives P10–P90 confidence intervals — forecasting as a function of the ontology, not a separate spreadsheet.
Compliance Enforcement
Obligations encoded as system constraints
Insurance, licenses, safety certifications — modeled as requirements with defined lifecycles. The ontology enforces compliance as a precondition. Claims cannot be submitted until obligations are satisfied.
Multi-Party Contracts
A shared ontology across counterparties
Upstream and downstream contracts resolve to the same underlying model. Each party operates within scoped access boundaries — seeing their view of a single truth. No document exchange. No reconciliation.
Portfolio Intelligence
Derived analytics across the contract graph
Earned value metrics, cash flow projections, assessment erosion, and health scoring — computed from the ontology across your full portfolio. Intelligence that emerges from the model, not reports built on top of it.
From Contract to Payment
Four operations. Complete financial control.
Model the Contract
Define the ontology. Create the project, build the WBS, register variations. Establish counterparty relationships across upstream and downstream contracts. The model becomes the single source of truth for all downstream operations.
Track Execution
Claim against the model. Each period captures cumulative progress against every WBS item. Snapshots preserve state, enabling auditability across the contract lifecycle.
Forecast & Enforce
Model costs from first principles. Encode compliance obligations as system constraints. The ontology enforces preconditions — claims cannot proceed until the model's invariants are satisfied.
Certify Payment
Deliver financial truth. Net claims, retention, cumulative positions — derived, not entered. Payment certificates generated directly from the ontology. Certification is a function of the model, not a manual process.
Principles
Built on invariants, not assumptions.
Snapshot Integrity
Claims preserve the complete contract state at the moment of creation. Historical records are immutable — you can always reconstruct the financial position at any point in time.
Hierarchical Precision
Values cascade from leaf nodes to parents, computed not entered. The WBS hierarchy ensures that every rolled-up total is mathematically consistent with its components.
Retention Automation
Defined once at the contract level, applied consistently across every claim. Compliance is built into the model — not left to manual calculation or memory.
Shared Ontology
Both counterparties operate against the same model. There is no claimant version and assessor version — there is one ontology, with scoped access. Reconciliation becomes unnecessary.
Compliance as Precondition
Obligations are encoded in the model, not tracked in memory. The system enforces compliance as an invariant — claims cannot be submitted until preconditions are satisfied.
