CONSTRUCTION
Governance-native AI infrastructure for contractors, infrastructure, and project firms
Constitutional RuntimeWho this is for
General contractors, specialty trades, infrastructure delivery groups, project-management firms, and owner-side capital-project teams deploying AI where a wrong answer touches a schedule commitment, a safety-critical decision, a change-order valuation, or a design conflict. When a scheduling model resequences work, a submittal-review assistant approves, or a claims-analysis surface generates a position, the constitutional surface belongs upstream of the model, not after the RFI.
- General contractors and construction managers
- Infrastructure and heavy-civil delivery groups
- Specialty trades and mechanical-electrical contractors
- Owner-side project management and program groups
- Design-build, EPC, and integrated-delivery teams
Capability surface
Constitutional runtime
The PRAXIS 7-Gate pipeline enforces governance on every AI action. It stops when unsure. Evidence is mandatory. Defaults deny rather than guess. Schedule proposals, cost-estimate assists, submittal reviews, and safety-adjacent outputs inherit this posture by construction, not by superintendent overlay.
Project evidence chain
Every model output that touches a schedule, an estimate, a submittal, an RFI, or a change-order narrative is recorded to a tamper-evident, SHA-256 hash-chained evidence store. Owner audit, claims analysis, dispute review, and post-project inquiry trace by default, not retrofit.
Safety-adjacent decision posture
AI outputs adjacent to safety-critical decisions (site logistics, temporary works review, lift planning inputs, hazard classification) carry deterministic guardrails. Defaults deny where inputs are incomplete. Human-authority escalation is enforced upstream of any autonomous action.
Regulatory and standards alignment
Deterministic governance maps to occupational-safety regimes, engineer-of-record and architect-of-record obligations, building-code review posture, EU AI Act obligations on high-risk uses, and public-procurement transparency requirements. SOC 2 self-certified. ISO 42001 readiness-mapped.
Joint-venture and subcontract partitioning
Each project, JV, or subcontract carries its own governance envelope, evidence chain, and access boundary. Cross-project contamination and unintended data crossover between owner packages, JV partners, and specialty trades is blocked at the runtime layer.
Sovereign deployment
On-premise or private-cloud sovereign deployment for firms that cannot exfiltrate design files, schedules, or claims material to a vendor cloud. Evidence store and constitutional runtime run inside the boundary you already trust and audit.
Where governance meets the project
Construction AI applications compound risk when governance is retrofitted. ETHRAEON is designed for the classes of decision where schedule, cost, safety, and dispute exposure all matter.
- Scheduling and resequencing. Model-assisted schedule updates, look-ahead planning, and constraint analysis carry sealed provenance: input state, model version, guardrail state, and human authority for critical-path change.
- Estimating and change-order valuation. Cost-estimate assists, unit-price analysis, and change-order narrative drafts pass through the constitutional runtime with defensibility and source-attribution guardrails enforced by construction.
- Submittal, RFI, and design-conflict review. Model-generated reviews and conflict flags carry hash-chained provenance for engineer-of-record and architect-of-record sign-off and post-project audit.
- Claims and dispute analysis. Model-assisted claim position, delay analysis, and cost-impact narrative record the decision chain from raw daily-report data to owner-facing document.
Mapped ETHRAEON products
The operational problem in this sector is proving that an AI-assisted construction artifact was governed: that a schedule, submittal, or safety narrative cited real records, that the documentation workflow ran with checkpoints that survive a dispute, and that a named engineer-of-record or architect-of-record held authority. Three ETHRAEON products map onto that as one governed workflow. The deliverable is a source-bound submittal-and-schedule provenance pack for a documentation decision across the site and project.
FactPulse Pro
Live runtime, available by subscription. For a submittal narrative, a schedule-and-cost synthesis, or a safety report, FactPulse Pro grades each supporting claim against its cited source (drawing, spec, daily log) with a confidence score, an expert-review flag, and a source-credibility rating, persists the governed intake, and exports the full JSON for the project record. It verifies and cites; it never approves a submittal.
Multi-Agent Orchestrator
Live runtime, available by subscription. For the multi-step documentation workflow it decomposes the task into scoped assignments, gates each step, enforces concurrency and budget, keeps adjudicator, coordinator, and executor separated, records rollback, and returns a hash-chained verb log plus a SHA-256 evidence node for dispute and audit review.
SOVRIN 1.0
Operational governance platform, SOC 2 self-certified and ISO 42001 and EU AI Act readiness-mapped. SOVRIN 1.0 holds the sovereignty posture under the pack, orchestrating AI-assisted reasoning and monitoring without loss of trace fidelity or operator sovereignty, with role-based access control, sovereign identity, and session seal keeping project and contract data inside the boundary.
Deliverable: a source-bound submittal-and-schedule provenance pack for a documentation decision. It maps against occupational-safety regimes, engineer-of-record and architect-of-record obligations, building-code review posture, EU AI Act high-risk obligations, and public-procurement transparency requirements.
Design approval, submittal sign-off, and safety determinations stay with the engineer-of-record and architect-of-record; the runtime produces the evidence.
Proof surface
ETHRAEON runs its own operations under constitutional governance. 300 plus production surfaces, 700 plus governance directives executed and evidenced, a hash-chained evidence store, and a substrate registry that reports live status. The infrastructure is the demonstration.
Engagement
Construction engagements start with a governance briefing scoped to your delivery model, project portfolio, and current AI deployment surface. The briefing produces a written architecture assessment and a deployment path proposal. From there: pilot, evidenced production integration, or sovereign private-cloud install.
Portfolio anchors
ETHRAEON is a constitutional runtime and evidence control layer. Portfolio posture: 16 filed U.S. provisional applications / 75 technical specifications / 9 families. Public claims are calibrated. AGI-class and ASI-class positioning is architectural, not an achievement claim.
