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":"0b7287b7-2cd2-4fb9-96f0-71fe7fded239","date":"2017-08-07","amount":25000.0,"department":"Unknown"},{"id":"df2b7f59-7012-48b6-b4e3-bd8a811c936b","date":"2017-08-07","amount":25000.0,"department":"Unknown"},{"id":"c25f8a9d-7093-4454-ba6c-2048bceaa795","date":"2017-10-05","amount":61170.0,"department":"Unknown"}],"window_days":90,"content_hash":"f66ecec12c2d26083598035eb49bc969bd2ee751c8cdcdbd918fa493bdc705e8","combined_total":111170.0,"contract_count":3},"published":true,"created_at":"2026-05-27T12:10:41.252336Z","related_entity_type":null,"related_entity_id":null,"reviewed_by":null,"reviewed_at":null,"reviewer_notes":null,"source_document_ids":null}
