PIID
Persistent Infrastructure Identity
PIID Sector Use Cases
Insurance
Anchor underwriting, inspection, risk, and claims data to a persistent asset identity instead of fragmented system records.
Government
Maintain asset visibility across departments and contractors so records stay connected through the entire asset lifecycle.
Construction
Assign identity at installation so documentation, inspections, and system histories remain attached from day one.
Facility Management
Maintain a continuous system of record across ownership changes, vendor transitions, and software migrations.
The Identity Layer for the Built World.
PIID assigns permanent, verifiable identifiers to physical infrastructure systems so records, inspections, and lifecycle data remain attached to the asset across ownership changes, software transitions, and decades of operation.
Today, critical infrastructure is managed through fragmented systems, disconnected documentation, and temporary identifiers. When projects are handed off, ownership changes, or software platforms are replaced, the asset often loses the continuity of its digital record. This is not a workflow issue. It is a missing foundation. Without a persistent identity layer, infrastructure data becomes unreliable over time, institutional memory breaks down, and lifecycle visibility disappears when it is needed most.
The missing layer
PIID is the permanent digital anchor for physical assets. PIID establishes a system-agnostic identity for infrastructure assets. It does not replace asset management systems, GIS platforms, inspection tools, underwriting systems, or operational software. It gives them a stable reference point.
With PIID, all lifecycle records can remain linked to the same underlying asset, creating continuity across design, construction, inspection, maintenance, repair, transfer, and long-term operation.
PIID is built on four foundational elements:
01
Infrastructure Origin Domains
Define the physical context where infrastructure systems originate, terminate, or remain accessible for inspection and documentation. These domains create the spatial anchor required for persistent identity.
02
Persistent Infrastructure Identifiers
Assign a deterministic, permanent identity to infrastructure systems independent of ownership, software platforms, or document repositories.
03
Lifecycle Governance Records
Create an append-only history of installation, inspection, modification, transfer, and other material events tied to the asset over time.
04
Identity Continuity
Ensures the identity remains anchored to the infrastructure asset itself, even as owners, vendors, contractors, or systems change.
