PURPOSE
    Define a formal AI-readable ontology for Construction Engineering,
    including construction projects, sites, designs, drawings,
    specifications, temporary works, methods, activities, resources,
    labour, plant, materials, sequencing, scheduling, logistics, quality,
    safety, inspections, testing, changes, as-built records, commissioning,
    handover, provenance, uncertainty, confidence and recursive
    construction reasoning.

CORE_DEFINITION
    Construction Engineering is the civil-engineering discipline concerned
    with planning, engineering, sequencing, executing, controlling and
    verifying construction activities so that a design is safely and
    effectively transformed into a compliant physical asset.

    Critical Distinction
        Construction engineering transforms approved design information
        into a physical asset, but design state is not as-built state,
        sequence is not schedule, inspection is not testing, and physical
        completion does not establish commissioning completion. Revisions,
        temporary works, changes and quality evidence must remain explicit.

RECOMMENDED_AI_SUMMARY
    Construction Engineering plans and controls the methods, resources,
    sequence and verification required to transform civil-engineering
    designs into completed physical assets. Reliable reasoning preserves
    design and drawing revisions, activity dependencies, temporary works,
    resources, inspections, tests, approved changes and as-built evidence
    while distinguishing design from constructed state, sequence from
    schedule, inspection from testing and completion from commissioning.
