Certification
Infrastructure Certification
Infrastructure Certification is DICRI's certification of demonstrated conformance between the applicable Engineering Basis and the observed physical condition of infrastructure, supported by Governed Engineering Evidence.
Certification establishes a Governed Engineering State: what the evidence and the applicable Engineering Basis support about infrastructure at a defined point in time. Because infrastructure changes through its lifecycle, each certified state is preserved as part of a governed history that later states extend rather than rewrite.
What Infrastructure Certification Establishes
Infrastructure Certification begins from the Engineering Basis that applies to the infrastructure: the applicable requirements, such as approved designs, specifications, codes and regulatory requirements, against which evidence and observed conditions are evaluated.
The applicable Engineering Basis is established before the Engineering Determination is made. Where several sources govern the same condition, their applicability and precedence are established by the engineering, regulatory, contractual or other competent authority governing the work. DICRI evaluates against the applicable Engineering Basis; it does not act as the design authority that decides which requirements should apply.
Governed Engineering Evidence establishes the observed physical condition of the infrastructure. Engineering Evidence Evaluation examines that condition against the applicable Engineering Basis, and the resulting Engineering Determinations remain traceable to both. The DICRI Assurance Framework sets out the conditions under which that evidence can support Engineering Confidence; certification applies that assurance basis in a formal institutional determination.
Certification keeps three questions distinct.
- Evidentiary sufficiency
Does the governed evidence establish the condition necessary to evaluate it?
Where it cannot, conformance remains unresolved rather than assumed.
- Engineering conformance
Does the condition the evidence establishes conform to the applicable Engineering Basis?
Sufficient evidence may establish a conforming or a nonconforming condition.
- Regulatory conformance
Where regulatory requirements form part of the applicable Engineering Basis, does the established condition satisfy them?
Certification does not replace the approvals, permits or jurisdiction of the authorities responsible for those requirements.
What certification establishes is a Governed Engineering State.
“A governed representation of an infrastructure condition established at a defined point in time through applicable engineering evidence, engineering context, determination, and assurance relationships.”
A Governed Engineering State records what the governed evidence and the applicable Engineering Basis supported within a defined scope and at a defined point in time. It does not warrant future performance, and it is not a claim that the infrastructure's physical condition remains unchanged.
Not every DICRI-governed assurance engagement results in an infrastructure certificate. DICRI-governed evidence and Engineering Evidence Evaluation may support an Engineering Determination without establishing a Governed Engineering State through certification.
Certification Through the Infrastructure Lifecycle
Infrastructure does not possess a single permanent engineering state. Its condition develops through commissioning, operation, maintenance, repair, modification and renewal, and engineering evidence accumulates as those conditions are established.
DICRI certification follows that history. Each certified state remains attributable to its own evidence, Engineering Basis and point in time.
At commissioning
Birth Certificate
What condition was established when the infrastructure entered service?
Establishes the Governed Engineering State of infrastructure at commissioning. Construction and delivery evidence may support that state; the certificate is defined by the state established at commissioning.
Its preserved evidence provides the basis on which later reliance on the commissioning state may begin.
In service
Operation and change
Maintenance, repair, replacement, modification, environmental exposure and operational events may change the infrastructure and its context, and engineering requirements may also change. These changes do not invalidate the states established before them.
Later in service
Health Certificate
What governed condition can be established for the infrastructure now?
Establishes a subsequent Governed Engineering State for infrastructure already in service, through governed evidence sufficient for the defined assessment scope at the time of evaluation.
It extends the governed history rather than rewriting it, and may itself be followed by later Health Certificates.
Governed history
The governed record preserves each certified state in sequence, with the evidence, Engineering Basis and determinations on which it rests. A later state may become the applicable position for a later decision; the earlier state remains attributable to its own evidence, basis and evaluation context.
New engineering states extend the governed history. They do not rewrite it.
A Health Certificate does not replace the Birth Certificate, and certification does not follow a fixed schedule. A later certificate may be warranted when a lifecycle intervention, observed change, elapsed time, operational event, regulatory requirement or another assurance need calls for the condition to be established again; its scope follows the assurance requirement that gives rise to it.
Evidence capture may occur across authorized organizations, professionals and locations, and governed evidence may be produced through any authorized evidence pathway that satisfies the applicable evidentiary and assurance requirements. Certification authority remains centralized: DICRI infrastructure certificates, including Birth Certificates and Health Certificates, are issued only by DICRI.
What a Certification Rests On
A DICRI infrastructure certificate communicates an engineering position without reproducing all of the evidence behind it. Its authority comes from the governed record on which it rests: the certificate remains traceable to that record, and it cannot represent an engineering position stronger than the record supports.
Documents, photographs, inspection forms, test results and checklists may each contribute evidence. Their presence alone establishes neither their evidentiary meaning nor the engineering position they can support. A certification rests instead on the following, considered together rather than as steps in a sequence.
Defined scope
The infrastructure, conditions and requirements the certification addresses. What was evaluated, and against what, remains associated with the certificate, so it is not read as a statement about an asset, system or lifecycle beyond that scope.
Applicable Engineering Basis
The authorized requirements governing each condition evaluated, identifiable by source and applicable version so that the evaluation can be reconstructed.
Governed Engineering Evidence
Evidence that establishes the characteristics, context and relationships the applicable evidentiary requirement calls for, and that remains attributable to the infrastructure and activity it represents.
Evaluation and Engineering Determination
Engineering Evidence Evaluation of the evidence-established condition against the applicable Engineering Basis, and the Engineering Determinations it supports. Evaluation establishes the determinations; certification is a separate institutional determination, made by DICRI when the defined certification requirements are satisfied.
Assurance relationships
The evidence was produced under the applicable professional and equipment assurance conditions, and the relationships that establish its origin and integrity remain intact. A professional credential supports eligibility for an activity; it does not by itself make evidence valid.
Governed record
The evidence, Engineering Basis, evaluation and determinations are preserved with their material relationships, so that an authorized relying party can trace the certificate to them and examine them independently of the people and organizations that produced them.
Limitations remain part of the governed record and constrain what the certificate can represent. DICRI may certify only the defined scope for which the evidence supports the applicable Engineering Determination. Where a material requirement within that scope cannot be determined, the affected condition remains unresolved rather than being represented as conforming. Any exclusions or scope limitations remain explicit and attributable, and scope is not narrowed to set aside a requirement the certification depends on. Certification cannot create authenticity or provenance that the evidence did not possess.
These requirements attach to the evidence and the pathway through which it was produced, not to any particular tool or platform. The conditions that make evidence trustworthy are set out in The DICRI Assurance Framework.
