The AI-native Construction Operating System

90% of construction projects finish late. Average budget overrun is 66%. Construction accounts for 20% of all workplace fatalities. ConstructionOS deploys 13 AI agents to detect risks 14 days before they become critical — while there's still time to act.

The Root Problem

Construction is the world's largest industry running on clipboards

A $12 trillion global industry with the worst productivity growth of any sector. The problem isn't the people — it's the absence of intelligence infrastructure. No system sees across the whole project until the damage is done.

📅
Schedule Overruns Cost Lives and Livelihoods
A 1-month delay on a $100M project costs $800K–$1.2M in prolongation: site prelims, supervision, equipment hire, and contractor claims. ConstructionOS detects CPM schedule risks 14 days before critical path impact — while mitigation options still exist.
💰
Cost Overruns Are the Industry Norm
66% average overrun across major projects (McKinsey, 2024). Root causes: poor change management, scope creep, material price escalation, and rework. Earned Value Management with AI forecasting changes EAC from a lagging indicator to a leading one.
⛑
Safety Incidents Are Preventable
1 in 5 worker deaths occurs in construction. Average cost per workplace fatality: $1.9M in legal, regulatory, and project disruption costs. 85% of site incidents have advance warning signals — missed permit expirations, PPE non-compliance, toolbox talk gaps — that AI detects in real time.
📝
RFI Delays Cascade Through Programmes
Average RFI response: 3 working days. A construction programme may have 500+ RFIs — that's 1,500 engineer-days of waiting. ConstructionOS drafts responses in 4 hours with clause citations. Engineer review: 15 minutes. Net saving: 2.5 days per RFI.
📦
Supply Chain Blind Spots
Post-COVID supply chains remain fragile. Single-sourced materials (bitumen, structural steel, specialist MEP equipment) create hidden critical path dependencies. Procurement AI identifies supply risks 6–8 weeks ahead — before they become programme emergencies.
🏗
BIM Clash = Rework = £££
Undetected BIM clashes between structural, MEP, and architectural models cost an average of $17,000 per clash in rework. A 100-unit residential project typically has 80–200 clashes. AI clash detection resolves 90% before construction begins.

"Safety decisions are always human. Contractual actions require engineer sign-off. ConstructionOS generates the intelligence — the site team acts on it. The liability for every action remains where it belongs: with the licensed professional."
— ConstructionOS Governance Principle
Construction AI Governance

Advisory intelligence, human authority

⛑
Safety: Always Human
AI detects safety hazards and alerts immediately but never issues stop-work orders autonomously. Site supervisor confirms and acts. Life-safety decisions require licensed HSE professional judgment — always.
📝
Contractual Actions: Engineer Approved
RFI responses, variation orders, NCRs, and contractual notices require engineer sign-off. AI generates drafts — humans approve. Legally binding only with authorised signature under NEC/JCT/FIDIC.
📊
ISO 19650 BIM Compliance
All document management logged per ISO 19650 Common Data Environment requirements. Full audit trail for employer information requirements. Level 2 BIM compliance built in.
🔐
GDPR Camera Compliance
Safety camera AI detects PPE compliance without facial recognition. No biometric data stored. Workers notified of monitoring. GDPR Article 9 special category data protections observed.
📁
Contractual Notice Tracking
NEC Early Warning and Compensation Event notices, JCT architect's instructions, and FIDIC Engineer's determinations tracked with deadlines. Missed notice = lost entitlement. AI ensures no deadline is missed.
📸
Photo Evidence Chain
All quality inspection photos time-stamped, geo-tagged, and stored in immutable record. Creates defensible evidence chain for claims, defects liability, and dispute resolution.
