When the combined value crosses a procurement-approval threshold but each individual award stays below it, the pattern is classically called 'contract splitting' and warrants further review against the procurement code and any sole-source justifications. The pattern can also reflect legitimate phased work or multiple unrelated services with the same vendor. Tier 2: vendor-named observation, no individual characterization.","fiscal_year":null,"review_status":"auto","review_tier":2,"evidence":{"vendor":"C3 Mechanical","contracts":[{"id":"50a52391-c814-4058-8208-b35b08f4fbbe","date":"2019-03-15","amount":77210.0,"department":"Unknown"},{"id":"8b02eb7c-596b-41e5-8d99-b44a095e86bd","date":"2019-05-10","amount":185000.0,"department":"Unknown"}],"window_days":90,"content_hash":"03777c6419ecb8e4d38174696387165dd479ca9f4062701774d34a101fc27ef3","combined_total":262210.0,"contract_count":2},"published":true,"created_at":"2026-05-27T12:10:40.867373Z","related_entity_type":null,"related_entity_id":null,"reviewed_by":null,"reviewed_at":null,"reviewer_notes":null,"source_document_ids":null}
