From an outcome
to the work it needs.
Toy scenario
Imagine delivering a tunnel beneath the Solway.
A finished tunnel needs more than permanent lining: excavation, temporary access and support, installed systems, inspections and evidence all play different roles. Smaller installation examples let us test those distinctions without pretending to engineer the whole tunnel.
Can a description of the desired result explain the work needed to achieve it?
Solway is an experimental setting for semantic project planning. Can we explain the work a goal requires by distinguishing physical products, processes, temporary means and evidence?
Inspect the construction
The work that must exist
Change scope, access or methods. Follow shared work and causal support, try two work breakdowns, and compare ontology with executable PDDL.
The broader tunnel ontology remains available for exploration. The app collection includes separate investigations of temporal relations, local-to-global construction and ontology auditing.
These are synthetic experiments. Model checks establish results within declared assumptions; they do not establish an engineered tunnel design or practitioner validation.
