Stable section ID: S05-CON-013-SECTION-3 · 308 content blocks
Lifecycle State Architecture
The System05 Lifecycle State Architecture shall define the recognized conditions through which a building or engineering asset may progress from initial concept to final disposition.
A lifecycle state shall describe more than chronological age. It shall identify the approved configuration, responsible authority, physical condition, information completeness, verification status, permissible actions, and transition requirements applicable to the asset.
Lifecycle states may exist at different scales. A building may remain in operation while one Cartridge is under repair, another is being upgraded, and a recovered component is undergoing requalification. The architecture shall therefore support nested and concurrent states without losing overall configuration control.
Every state shall define:
- Entry conditions.
- Required information.
- Responsible authority.
- Permitted activities.
- Monitoring and evidence requirements.
- Exit conditions.
- Approved next states.
- Safe response to incomplete or failed transitions.
- Concept and Planning State
The Concept and Planning State begins when a potential System05 asset, project, building, expansion, or major lifecycle intervention is formally proposed.
During this state, stakeholders shall define:
- Intended functions and users.
- Site and regional conditions.
- Regulatory context.
- Performance objectives.
- Expected service life.
- Affordability constraints.
- Expansion and adaptation expectations.
- Environmental and resource conditions.
- Manufacturing and supply capabilities.
- Operational and maintenance capacity.
- Recovery and end-of-life objectives.
- Required digital and automation capabilities.
Decisions made during planning shall be recorded as assumptions, requirements, constraints, or unresolved risks. Preliminary concepts shall not be represented as verified engineering configurations.
The state shall conclude when the project basis, decision authority, lifecycle objectives, and required engineering inputs are sufficiently defined to authorize design and engineering.
Design and Engineering State
The Design and Engineering State converts approved lifecycle objectives into a coordinated System05 configuration.
Design shall define the relationships among Nodes, Cartridges, Interfaces, structural systems, enclosure systems, utilities, sensors, digital architecture, maintenance access, robotic access, and future recovery pathways.
Lifecycle design activities shall include:
- Service-life planning.
- Material and exposure assessment.
- Interface and compatibility definition.
- Inspection and maintenance planning.
- Replacement and upgrade planning.
- Adaptability and expansion planning.
- Design for controlled disassembly.
- Lifecycle risk assessment.
- Whole-life cost and environmental evaluation.
- BIOS and Digital Twin information requirements.
- Verification and acceptance planning.
The design shall distinguish approved requirements, calculated performance, assumptions, reference solutions, and unresolved conditions. Transition to manufacturing shall require an authorized and version-controlled engineering baseline.
Manufacturing and Supply State
The Manufacturing and Supply State begins when an approved engineering baseline is released for procurement or production.
During this state, physical assets shall be produced, identified, inspected, documented, protected, stored, and transported in accordance with applicable specifications.
Required lifecycle information may include:
- Global and local identifiers.
- Manufacturer and production facility.
- Material and component provenance.
- Manufacturing date and batch.
- Approved design and interface version.
- Quality-control results.
- Nonconformities and approved dispositions.
- Storage and transportation limits.
- Service-life assumptions.
- Maintenance and recovery instructions.
- Applicable certification evidence.
Changes to design, material, process, or supplier shall be evaluated through configuration control. Delivery to the assembly stage shall not be accepted solely on physical presence; identity, condition, compatibility, and required evidence shall also be verified.
- Assembly and Construction State
- The Assembly and Construction State transforms manufactured assets into a coordinated physical building.
Assembly shall follow approved sequences, interface requirements, temporary-state rules, tolerance limits, safety procedures, and configuration records. The physical load path and required connection states shall be verified before temporary support or installation equipment is released.
Lifecycle-relevant records shall include:
- Component identities and installed locations.
- Interface versions and connection status.
- Installation date and responsible party.
- Alignment and tolerance evidence.
- Inspection and test results.
- Field modifications.
- Damage or contamination events.
- Concealed-condition evidence.
- Temporary conditions and unresolved work.
- Deviation approvals.
The Building BIOS and Digital Twin shall be updated to reflect verified installation. Construction progress alone shall not authorize transition to commissioning where required evidence, inspections, or safety conditions remain incomplete.
Commissioning and Handover State
The Commissioning and Handover State confirms that the assembled building is ready to enter its intended operational use.
Commissioning shall verify:
- Structural and interface completion.
- Building-system functionality.
- Safety-system performance.
- Sensor and communication operation.
- BIOS configuration completeness.
- Digital Twin alignment.
- Operational limits and control logic.
- Maintenance and inspection requirements.
- Emergency procedures.
- Outstanding deficiencies and temporary conditions.
- Training and handover documentation.
An initial operational baseline shall be established using verified measurements, inspection evidence, configuration records, and accepted performance criteria.
Handover shall transfer responsibility without breaking the digital thread. Owners, operators, and maintainers shall receive the authority, information, access, tools, and training necessary to manage the asset safely. Unresolved conditions shall remain visible and assigned rather than disappearing during contractual or organizational transfer.
Occupancy and Operation State
The Occupancy and Operation State represents the period during which the building performs its intended functions for users.
Operation shall remain within approved safety, environmental, occupancy, loading, and system limits. Operational intelligence may use sensors, inspections, user reports, maintenance records, and Digital Twin analysis to evaluate performance and detect developing problems.
Operational management shall address:
- Energy and water use.
- Indoor environmental conditions.
- Structural and interface condition.
- Utility and equipment performance.
- Occupant safety and accessibility.
- Changes in use or loading.
- Environmental exposure.
- Software and control-system updates.
- Cybersecurity and data continuity.
- Upcoming maintenance and renewal needs.
Changes that affect approved configuration, performance, or risk shall initiate the appropriate review or transition process rather than being treated as undocumented operational adjustments.
Inspection and Maintenance State
The Inspection and Maintenance State may occur periodically, conditionally, or in response to detected anomalies while the building remains partially or fully operational.
Inspection shall determine whether the actual physical condition remains consistent with approved performance and lifecycle assumptions. Maintenance shall preserve intended function and prevent avoidable deterioration.
Activities may include:
- Visual and instrumented inspection.
- Sensor-data review.
- Connection-state verification.
- Moisture and corrosion assessment.
- Wear and fatigue evaluation.
- Cleaning, lubrication, adjustment, or calibration.
- Protective-coating renewal.
- Software and firmware maintenance.
- Minor component servicing.
- Update of condition and maintenance records.
Inspection results shall include the method, date, responsible party, evidence, observed condition, confidence, limitations, and required actions. Findings shall be connected to the relevant physical asset and BIOS configuration.
Repair and Replacement State
The Repair and Replacement State begins when an asset can no longer meet its required condition through routine maintenance alone or when continued operation requires restoration of performance.
The decision shall evaluate:
- Failure mode and root cause.
- Safety significance.
- Remaining service life.
- Repair feasibility.
- Replacement availability.
- Compatibility with current interfaces.
- Effects on adjacent systems.
- Temporary-support requirements.
- Cost, downtime, and environmental consequences.
- Future upgrade opportunities.
- Recovery potential of removed assets.
Repair shall restore verified performance without concealing unresolved damage. Replacement shall use an approved compatible component or a formally engineered adaptation.
Removed components shall retain their identities and transition to inspection, refurbishment, reuse, recovery, or final disposition. Completion shall require physical verification and update of the Building BIOS and lifecycle records.
Upgrade and Adaptation State
The Upgrade and Adaptation State supports deliberate improvement or modification of the building in response to new user needs, technologies, regulations, hazards, performance objectives, or available resources.
Possible changes include:
- Cartridge replacement.
- Utility modernization.
- Sensor and control upgrades.
- Energy-performance improvement.
- Spatial reconfiguration.
- Accessibility improvement.
- Structural strengthening.
- Climate-adaptation measures.
- Building expansion or contraction.
- Change of occupancy or function.
Proposed changes shall be checked against structural capacity, interface compatibility, lifecycle cost, maintenance access, safety, and effects on future disassembly.
Obsolete configurations shall remain traceable after upgrade. The new configuration shall not become authoritative until it has been verified, commissioned where required, and recorded in the Building BIOS.
Deconstruction and Disassembly State
The Deconstruction and Disassembly State begins when a building, subsystem, or component is intentionally separated for relocation, adaptation, recovery, or retirement.
Disassembly shall be treated as a controlled engineering process rather than demolition in reverse. Planning shall address:
- Current structural load paths.
- Temporary stabilization and support.
- Safe release sequences.
- Hazardous materials.
- Stored mechanical, electrical, or thermal energy.
- Worker and robot access.
- Component identities.
- Condition before and after removal.
- Protection of reusable assets.
- Sorting and transport requirements.
- BIOS and Digital Twin updates.
No structural or safety-critical connection shall be released without confirming that loads have been safely redirected or removed. Unplanned destructive separation shall be documented as a deviation and may reduce the reuse status of affected assets.
Reuse, Recovery and Reintegration State
The Reuse, Recovery and Reintegration State applies when a removed component, Cartridge, Node, assembly, or material is evaluated for continued use.
Recovered assets shall be classified according to identity, provenance, condition, previous exposure, damage history, remaining service life, interface compatibility, and available evidence.
Potential pathways include:
- Direct reuse.
- Repair before reuse.
- Refurbishment.
- Remanufacturing.
- Repurposing.
- Material recovery.
- Controlled recycling.
- Final disposal.
Reintegration into a System05 building shall require appropriate inspection, testing, requalification, configuration compatibility, and authorization. Previous certification shall not automatically remain valid after damage, uncontrolled storage, modification, or unknown service history.
- The asset’s lifecycle record shall preserve both its prior application and its new configuration.
- Retirement and Final Disposition State
The Retirement and Final Disposition State applies when an asset can no longer be responsibly retained, repaired, reused, refurbished, remanufactured, repurposed, or materially recovered at an acceptable level of safety and value.
Retirement decisions shall document:
- The reason continued use is unacceptable.
- Condition and failure evidence.
- Alternatives considered.
- Hazardous substances or residual energy.
- Recoverable subcomponents or materials.
- Required treatment or containment.
- Authorized disposal pathway.
- Responsible organization.
- Final transfer or destruction evidence.
Retirement of one component shall not imply retirement of the entire building or assembly. Recoverable value shall be separated before final disposal wherever practical.
Digital records shall preserve necessary historical, safety, compliance, and environmental information even after the physical asset has ceased to exist.
Lifecycle State Transition Rules
A lifecycle transition shall occur only when the exit requirements of the current state and the entry requirements of the next state have been satisfied.
Every controlled transition shall identify:
- The asset and current configuration.
- The initiating event or decision.
- Required technical evidence.
- Responsible parties.
- Decision authority.
- Safety and compatibility checks.
- Unresolved conditions.
- Effective date and time.
- New lifecycle state.
- Required BIOS and Digital Twin updates.
Transitions may be approved, conditionally approved, rejected, suspended, or reversed where technically possible. Failure to complete a transition shall place the asset in a defined safe or restricted state.
A physical change shall not be treated as formally complete until required evidence and configuration records are updated.
Lifecycle Gates and Decision Authorities
Lifecycle gates shall prevent assets from moving into higher-consequence states without adequate verification and authorization.
Typical gates may include:
- Approval to begin detailed design.
- Release for manufacturing.
- Acceptance for shipment.
- Acceptance for installation.
- Closure of structural connections.
- Authorization for commissioning.
- Approval for occupancy.
- Release after inspection or repair.
- Authorization for upgrade.
- Approval for structural disassembly.
- Requalification for reuse.
- Approval for retirement or disposal.
Gate authority shall correspond to the level of risk and applicable regulation. Routine maintenance may require operational approval, while structural modification or reuse of a critical Node may require licensed engineering review, testing, or third-party certification.
AI systems may support gate evaluation but shall not assume authority beyond explicitly assigned and governed limits.
Lifecycle Configuration Baselines
A configuration baseline shall define the approved state of an asset at a specific lifecycle point. It shall establish the reference against which later changes, inspections, failures, repairs, and upgrades are evaluated.
Important baselines may include:
- Approved design baseline.
- Manufacturing release baseline.
- As-manufactured baseline.
- As-delivered baseline.
- As-assembled baseline.
- Commissioning baseline.
- Operational baseline.
- Post-repair baseline.
- Post-upgrade baseline.
- Pre-disassembly baseline.
- Requalified reuse baseline.
Baselines shall identify applicable component versions, interfaces, materials, software, control logic, limits, evidence, and unresolved exceptions.
Previous baselines shall not be overwritten. They shall be superseded through version-controlled records so the complete configuration history remains reconstructable.
Lifecycle Events and Engineering Memory
A lifecycle event is any occurrence that changes, verifies, challenges, or provides meaningful evidence about an asset’s condition, configuration, performance, ownership, or future management.
Events may include:
- Manufacturing and certification.
- Shipment and storage.
- Installation and connection.
- Inspection and testing.
- Maintenance and calibration.
- Damage, overload, or environmental exposure.
- Fault detection and alarm.
- Repair or replacement.
- Software or control update.
- Change of ownership or operation.
- Upgrade or reconfiguration.
- Disassembly and recovery.
- Requalification, reintegration, or retirement.
Engineering memory shall preserve the sequence, context, rationale, evidence, responsible parties, and consequences of these events. It shall allow future stakeholders to understand not only what changed but why it changed and how confidence in the resulting state was established.
- Lifecycle Evidence and Data Provenance
- Lifecycle decisions shall be supported by evidence appropriate to their risk, consequence, and uncertainty.
Evidence may include:
- Engineering calculations.
- Material and manufacturing records.
- Inspection reports.
- Test results.
- Sensor observations.
- Images and dimensional scans.
- Commissioning records.
- Maintenance and repair documentation.
- Failure analysis.
- Manufacturer declarations.
- Third-party certification.
- Operator and occupant observations.
- AI-generated analysis.
Every evidence item shall record its source, date, method, asset relationship, responsible party, applicable configuration, confidence, limitations, and modification history.
Derived analysis shall remain distinguishable from direct observation. AI-generated conclusions shall identify the underlying data and model context. Missing, contradictory, or low-confidence evidence shall remain visible in lifecycle decisions.
Lifecycle Digital Thread and Traceability
The lifecycle digital thread shall connect requirements, designs, manufacturing records, physical identities, installation evidence, operational data, maintenance actions, configuration changes, recovery decisions, and final disposition records.
Traceability shall support movement in both directions. Stakeholders should be able to determine:
- Which requirement governed a component.
- Which design and manufacturing version produced it.
- Where and how it was installed.
- Which Interfaces and adjacent assets depend on it.
- What inspections, damage, repairs, and upgrades occurred.
- What evidence supports its current state.
- Whether it is eligible for continued use or recovery.
- Which later decisions were affected by it.
The digital thread shall remain usable across changes in software, ownership, manufacturer, or service provider. Critical lifecycle information shall not depend exclusively on a temporary proprietary platform.
Final Lifecycle State and Continuity Model
The Final Lifecycle State and Continuity Model establishes a controlled sequence of physical, digital, and organizational states extending from concept to final disposition.
The model requires that:
- Every significant asset has an identifiable lifecycle state.
- States may be nested across buildings, systems, Cartridges, Nodes, and materials.
- Every controlled transition has defined entry and exit conditions.
- Lifecycle gates correspond to risk and engineering authority.
- Configuration baselines preserve approved states without erasing history.
- Lifecycle events create persistent engineering memory.
- Evidence remains connected to its source, method, configuration, and confidence.
- The Building BIOS preserves authoritative configuration and lifecycle status.
- The Digital Twin represents verified physical and operational conditions.
- Physical transitions and digital updates remain synchronized.
- Ownership or organizational changes do not break responsibility or traceability.
- Recovery and reintegration continue the lifecycle rather than creating an undocumented new asset.
Through this model, System05 maintains engineering continuity across decades, multiple owners, changing technologies, repeated upgrades, and successive applications.
