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":"d97bdae3-bb57-499d-bdf1-8a936eb14b2a","date":"2016-11-29","amount":21125.0,"department":"Unknown"},{"id":"f7385d97-bde8-490b-9f69-c5cb3367affd","date":"2017-01-20","amount":37605.0,"department":"Unknown"}],"window_days":90,"content_hash":"297236205d6233ae584e7bc8c860e51d4c12d5b403a73f25aec763d78395eb08","combined_total":58730.0,"contract_count":2},"published":true,"created_at":"2026-05-27T12:10:40.855398Z","related_entity_type":null,"related_entity_id":null,"reviewed_by":null,"reviewed_at":null,"reviewer_notes":null,"source_document_ids":null}
