Predictive certainty for construction.
OntaBuild is an AI‑first platform that forecasts cost & schedule before you break ground, orchestrates the delivery process, and continuously learns from outcomes.
Built on Reference Class Forecasting + domain ontologies • Secure by design • Owner/GC/Designer aligned
Cost Window
P70: +$100K • P90: -$50K
Schedule Window
P70: +3mo • P90: +5mo
Top Drivers
- System complexity+0.7 mo
- Plan mix+$310k
- Weather risk+0.4 mo
Platform pillars
An epistemology‑first stack: curate the right data → formalize a domain ontology → drive forecastable outcomes.
Forecasting Engine
Reference Class Forecasting + causal features deliver probable cost & time windows with confidence bands.
Control Tower
Single pane to orchestrate scope, risk, logistics, and constraints across stakeholders.
Data Fabric
Ingest, normalize, and govern project data; preserve provenance and continuously learn from outcomes.
Assurance
Security, auditability, and explainability baked in; designed for enterprise & DoD compliance.
What you get
- Probabilistic cost windows with drivers you can interrogate.
- Predictive schedules that adapt to constraints and weather windows.
- Change‑order likelihood scoring and scope impact analysis.
- Decision playbooks that tie forecasts to contract & procurement actions.
From ROM to GMP
Estimate Intelligence
AI‑assisted estimating with live market signals and reference classes.
Dynamic CPM
Schedule Intelligence
Constraint‑aware plans with confidence bands and what‑if scenarios.
Scope clarity
Risk Lens
Detect ambiguity, quantify exposure, and pre‑empt change orders.
Operational view
Schedule Intelligence
Be aware of delays months to years ahead of traditional methods.
How it works
- 1
Collect
Unpack drawings, narratives, and history; unify cost & schedule taxonomies.
- 2
Model
Fit reference classes, causal features, and priors for your asset type.
- 3
Forecast
Generate distributions for cost & time; inspect drivers and assumptions.
- 4
Decide
Run playbooks to set delivery strategy, contracts, and procurement windows.
- 5
Learn
Close the loop with actuals; models improve with every project.
