Properties
Instance of
Non-ContractualThird-PartySafetyObservationDuty
http://proethica.org/ontology/intermediate#Non-ContractualThird-PartySafetyObservationDuty
Applied to
Owner Y's adjacent property
Subcontractor safety issues on Owner Y's property
Balancing with
Employer Intermediary Safety Escalation Obligation
Faithful Agent Obligation Within Ethical Limits
Scope-of-Work Limitation as Incomplete Ethical Defense
Concrete expression
Engineer A observes safety hazards on Owner Y's property — a party entirely outside the contractual web of the engagement — and the complete absence of any relationship between the engineer's engagement and the affected property does not extinguish the professional obligation to take reasonable steps to address the observed hazard
Confidence
0.88
Importance
high
Interpretation
This is the core ethical challenge of the case: the engineer's professional duty to public safety is not bounded by contractual relationships; the total absence of any nexus between the engagement and the affected property makes this a paradigm case for the principle that public welfare obligations attach to professional licensure, not to contractual engagement
Invoked by
Engineer A Construction Observation Engineer
Engineer A Out-of-Scope Adjacent Safety Observer
Tension resolution
The absence of a contractual relationship with Owner Y does not eliminate the duty; it shapes the form of the response (routing through employer and client as intermediaries) but does not permit inaction
Source Evidence
Source text
a party with whom neither Engineer A, ES Consulting, or Client X has any direct relationship
Text references
Engineer A observes potential safety issues relating to the performance of work by a subcontractor on a project being constructed on an adjacent piece of property for Owner Y, a party with whom neither Engineer A, ES Consulting, or Client X has any direct relationship
