Site Network and BIM Data Path Governance

Construction projects involve dozens of contractors sharing temporary networks on active sites. BIM models, structural calculations, and building management systems contain sensitive data that defines the physical security of the built environment.

"We found the BIM model for a Ministry of Defence facility on a contractor's personal laptop. It contained the complete security system layout, structural details, and utility routing. The contractor had left the project six months earlier."

Physical governance for construction data.

Construction firms gain physical control over BIM data, building management systems, and multi-contractor site networks. Contractor access is governed by time-limited, authorised windows. Sensitive project data is physically separated from general site networks. Long-term archives persist beyond temporary site infrastructure.

• Physical BIM data isolation from site networks
• Time-limited contractor access with multi-party authorisation
• Independent governance for each contractor organisation
• Cellular management independent of site infrastructure
• ISO 19650 compliance evidence throughout the project lifecycle
• Long-term data archives beyond construction phase

Sovereign Project Data

All BIM models and project data remain within the agreed jurisdiction in secured Firevault Bunkers, meeting government construction security requirements.

Multi-Contractor Governance

Each contractor organisation receives isolated access paths with independent authorisation and logging, preventing cross-contractor compromise.

ISO 19650 Compliance

Automated compliance logging supports ISO 19650 information management requirements and government construction security standards.

Site Cellular Management

Out-of-band management via cellular connectivity ensures governance capability independent of temporary site network infrastructure.

Project Audit Trail

Every access to BIM data and building systems is recorded in tamper-proof logs that persist beyond the construction phase.

Project Data Archive

Air-gapped copies of project data ensure long-term preservation beyond the life of temporary construction site infrastructure.

Project Security Assessment

Assess BIM data sensitivity, contractor access requirements, and building management system connectivity for the project or estate.

Site Zone Architecture

Design physically separated zones for general site access, BIM collaboration, building management, and corporate project systems.

Single Site Pilot

Deploy on a representative construction site with full contractor access governance, BIM data isolation, and compliance logging.

Estate-Wide Adoption

Standardised deployment across all construction sites with centralised data archives, continuous compliance evidence, and cellular management.
