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":"GRW Engineers","contracts":[{"id":"a1dde553-a48b-4e18-89a1-0d16f2c6b62b","date":"2013-04-01","amount":500190.0,"department":"Unknown"},{"id":"2c8d93f0-f11e-4fc6-9aa6-c2c0fdb19b9f","date":"2013-06-20","amount":199737.0,"department":"Unknown"}],"window_days":90,"content_hash":"9ac8b7154affb9c66b3fa86700b9f87d9e460dc67a7f0eaa075bf2cd23076435","combined_total":699927.0,"contract_count":2},"published":true,"created_at":"2026-05-27T12:10:41.235736Z","related_entity_type":null,"related_entity_id":null,"reviewed_by":null,"reviewed_at":null,"reviewer_notes":null,"source_document_ids":null}
