--- title: "Secure Construction Site Networks | Control" url: https://fire-vault.com/control-for-construction description: "Protect BIM data flows and secure temporary construction site networks with physical segmentation, isolating them from the corporate enterprise. Learn why." lang: en-GB --- Construction # 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. - BIM data theft - Contractor account compromise - Site Wi-Fi intrusion - Ransomware on project systems Back to Control: https://fire-vault.com/solutions/control Image: Construction site with tower cranes at dusk (https://fire-vault.com/assets/sector-square-construction-CEACpkgz.jpg) The exposure in numbers 01 BIM data path isolation from site networks 100% BIM data path isolation from site networks 02 Persistent contractor access between visits Zero Persistent contractor access between visits 03 Site network zones with independent governance 4 Site network zones with independent governance 04 BIM security and ISO 19650 compliance Full BIM security and ISO 19650 compliance The Challenge ## Construction sites present unique network risks. 01 ### BIM Data Exposure Building Information Models contain detailed structural, mechanical, and security system data that, if stolen, reveals the physical vulnerabilities of critical buildings. 02 ### Multi-Contractor Access Dozens of subcontractors share temporary site networks with varying security standards, each creating potential entry points for attackers. 03 ### Temporary Infrastructure Construction site networks are inherently temporary and often lack the security controls applied to permanent corporate infrastructure. Construction > A stolen BIM model does not just represent intellectual property loss. It provides a complete blueprint of a building's physical security systems, structural weaknesses, and access points. The Scenario ### Scenario: BIM Data Theft from Critical Infrastructure Project A subcontractor's laptop, connected to the construction site Wi-Fi, is compromised through an unpatched vulnerability. The attacker uses the site network to access the BIM collaboration server, downloading complete structural and security system models for a new government building. The models reveal every security camera location, access control point, and structural reinforcement detail. With Control, the BIM collaboration environment is physically separated from the general site network. Subcontractor access to BIM data requires multi-party authorisation and operates within controlled time windows. The compromised laptop cannot reach BIM systems because the path does not exist. "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." Module deployment · construction network ## Where each Control module is deployed across office, project, site and supply chain. Construction networks carry an office estate, project systems that hold BIM and designs, site networks that link plant and IoT, and a deep supply chain. Control puts a real boundary at the places that matter. Grounded in PAS 1192-5 / ISO 19650-5 and NCSC supply chain guidance.
