Construction projects depend on connections. Not all need to stay open.

BP-13 Construction Control Blueprint icon

Temporary site networks bring contractors, project systems and building information models together. Control introduces physical control at selected boundaries so approved access can be available when needed and disconnected outside that work.

A design supplier needs access to one BIM collaboration environment rather than the wider project estate. Review the named support and cross-zone boundaries; operationally required links are not assumed disconnectable.
Reference design for adaptation with the service owner, not a validated deployment. Confirm complete boundary coverage, operational dependencies and the consequences of opening or closing each selected path.

Control does not replace construction information management, site safety, access governance, backups or security monitoring. Changing connectivity does not establish a safe process state, stop local execution or guarantee service restoration.

The industry reality

Construction: the connections your operation relies on.

Construction environments combine temporary infrastructure with sensitive BIM models, structural calculations and building management systems. A compromised contractor device or poorly governed link may expose project information or affect connected operations.

Model exposureBIM models may reveal structural details, utility routes and security arrangements.

Contractor reachShared site networks can make it difficult to distinguish approved access from persistent connectivity.

Project disruptionLoss of project systems may complicate coordination, handover or planned construction work.

Systems dependencyBuilding management and commissioning paths require careful treatment around live services.

What needs protecting

The service, systems and people behind the connections.

A design supplier needs access to one BIM collaboration environment rather than the wider project estate. Review the named support and cross-zone boundaries; operationally required links are not assumed disconnectable.

Standing accessWhich contractor paths remain available outside approved project work?

Shared infrastructureCould temporary site connectivity provide a route to project or building systems?

HandoverWhich connections and records need a defined owner when the site closes?

Threats and failure scenarios

Situations to plan for, before the next incident.

A design supplier needs access to one BIM collaboration environment rather than the wider project estate. Control acts on selected physical connections, not every connection in the environment.

Scoped support for ConstructionA design supplier needs access to one BIM collaboration environment rather than the wider project estate. The owner authorises the selected route and its closing conditions.

Review an affected boundaryReview the remote site support connection while keeping life-safety and building-control dependencies outside assumed isolation scope.

CP-16: agree the connection and authorityReview the remote site support connection while keeping life-safety and building-control dependencies outside assumed isolation scope. Use CP-16 only where its scope and approval requirements fit this connection.

Recommended industry Blueprint

Our recommended Blueprint for Construction.

A design supplier needs access to one BIM collaboration environment rather than the wider project estate. Control acts on selected physical connections, not every connection in the environment.

Start with these connections: Design supplier to BIM collaboration environment; Site network to project administration
Agree how access works: Open only for the authorised support task; close under agreed completion conditions
Plan the response: Change only the selected boundary after the service owner approves the impact

Refine this recommendation with project owners, site operations and security leads. Offline Secure Storage® can hold recovery copies separately; it is not a Control module.

Operational scenarios

Who decides, what changes, and what is checked.

Agree responsibility and service dependencies before relying on a controlled connection.

Normal operation
Temporary site networks bring contractors, project systems and building information models together. Control introduces physical control at selected boundaries so approved access can be available when needed and disconnected outside that work.
Approved work
A design supplier needs access to one BIM collaboration environment rather than the wider project estate. The owner authorises the selected route and its closing conditions.
Incident response
A design supplier needs access to one BIM collaboration environment rather than the wider project estate. Control acts on selected physical connections, not every connection in the environment.
Reconnection
The owner reviews service dependencies and security checks, authorises reconnection and verifies the observed result. Evidence is retained only through the specified supporting systems.

Control does not replace construction information management, site safety, access governance, backups or security monitoring. Changing connectivity does not establish a safe process state, stop local execution or guarantee service restoration.

Resilience and recovery

Offline Secure Storage®

OSS protects stored business data, recovery copies and retained evidence through physical disconnection. It is a separate storage service, not a Control module or a network containment function.

Control by Firevault governs selected physical connections. Existing detection tools and authorised operators decide when to act. OSS does not detect incidents, command Control or replace operational safety procedures.

Offline Secure Storage (OSS) is separate from Control. If selected, it can hold retained copies of configurations, records or recovery material. Collection, completeness and recovery readiness depend on the supporting tools, retention design and tested recovery procedures.

Standards and governance

Support your obligations. Keep the boundaries clear.

Alignment may be assessed against ISO 19650 information management practices; no certification or compliance outcome is implied. Any assessment needs deployment-specific scope and evidence; this Blueprint provides no certification, complete audit trail or guaranteed response time.

What this addressesA design supplier needs access to one BIM collaboration environment rather than the wider project estate. Control acts on selected physical connections, not every connection in the environment.

What it does not replaceControl does not replace construction information management, site safety, access governance, backups or security monitoring. Changing connectivity does not establish a safe process state, stop local execution or guarantee service restoration.

Evidence agreed for the deploymentSpecify the requests, approvals, commands, observed states and test results to retain. Logging capability and retention depend on the selected design.

Detection and the decision to act belong to the operational owner and supporting security systems. Identity, approval workflow, session expiry and evidence collection require specified integrations. Execute initiates an approved action; Fracture physically disconnects the selected path through Firebreak hardware. Confirm the observed connection state separately. Anchor keeps critical assets within defined physical connection boundaries; it does not collect or retain records. Transfer governs a designated exchange path, not content inspection or de-identification.

Deployment and proof of concept

Start with one boundary. Test it. Then expand.

Review the first selected connection with project owners, site operations and security leads, agree who can authorise a change and test the service impact.

Map the complete boundary
Confirm cabling, redundant links and alternate routes. A selected physical cut does not remove paths outside its scope.
Agree an independent command route
Confirm the available command methods for the selected hardware. Command delivery can be affected by coverage, roaming and handshakes.
Test the effect, not just the command
Verify the observed link state, service dependencies and failure behaviour in an agreed test window.

Plan your first route

Start with the route you would close first.

Review the first selected connection with project owners, site operations and security leads, agree who can authorise a change and test the service impact.

Outcomes

What changes, and how you will verify it.

Judge the Blueprint on agreed, observed outcomes.

Design supplier to BIM collaboration environmentOpen only for the authorised support task; close under agreed completion conditions. Agree identity checks, approval, session closure and observed-state checks

Site network to project administrationChange only the selected boundary after the service owner approves the impact. Map alternate routes and preserve services outside the selected scope

Building-control or life-safety functionsNot assumed disconnectable. Safety and continuity owners must assess this dependency separately

Questions worth asking

Before you rely on BP-13.

Practical questions for the people who own these connections.

Not by assumption. Map dependencies and agree the acceptable service impact with the operational owner before selecting a path.

Review the first selected connection with project owners, site operations and security leads, agree who can authorise a change and test the service impact.
