Platform modules
Use modules independently or as a unified stack. All are explainable, auditable, and governed.
Cost & Schedule
Forecasting Engine
Reference classes + causal features produce probabilistic windows with confidence bands and top drivers.
- P50 / P80 / custom targets
- Driver interrogation
- Scenario runs
Orchestration
Control Tower
Move from forecast to action—link scope, logistics, procurement, contracts, and constraints.
- Delivery playbooks
- Constraint board
- Variance tracking
Provenance & Learning
Data Fabric
Ingest, normalize, and govern data from drawings to field events; maintain lineage and drift alerts.
- Taxonomy unification
- Signed lineage
- Feedback loops
Security & Compliance
Assurance
Role‑based access, audit logs, and explainability features designed for enterprise & public sector.
- RBAC / SSO / SCIM
- Private enclaves

Deep dives
Forecasting Engine
Probabilistic, explainable, and built for scrutiny.
- Reference classes tuned by asset type and region
- Causal features (complexity, labor mix, logistics, weather)
- Confidence bands & coverage metrics (P50/P80 hit rates)
- Driver attribution with rationale and priors
Control Tower
Turn forecasts into aligned action.
- Delivery model selection (CMAR, DBB, DB, etc.)
- Contract playbooks tied to risk profiles
- Procurement window predictions & vendor curation
- Variance tracking and course‑correction guidance
Data Fabric
From field data to board decisions.
- Unified cost & schedule taxonomy
- Signed data lineage and provenance graph
- Model drift detection & feedback capture
- APIs for BIM/ERP/PM tools
Assurance
Security and governance by default.
- RBAC, SSO, SCIM; private cloud options
- Public‑sector alignment (ICE, IGCE, controls)
- Configurable retention & compliance policies

FAQ
How does OntaBuild generate forecasts?+
We fit reference classes to your asset type and region, enrich with causal features, and output distributions (P50/P80). Drivers and priors are explainable and auditable.
Can we use modules without a full platform rollout?+
Yes. Teams often start with Forecasting Engine, then adopt Control Tower and Data Fabric as workflows mature.
What integrations are supported?+
We provide APIs and connectors for common BIM/ERP/PM tools. Enterprise and Public Sector editions include SSO/SCIM.
How do you handle sensitive data?+
Role‑based access, private enclave options, signed lineage, and exportable audit artifacts are available by default.
