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":"WSP USA","contracts":[{"id":"08700a60-ba0f-40a7-801d-a2affd3e7d09","date":"2019-10-28","amount":220000.0,"department":"Unknown"},{"id":"31962bd9-b4e0-42ac-8f89-e164d4fa0691","date":"2020-01-06","amount":222000.0,"department":"Unknown"}],"window_days":90,"content_hash":"9fc7decc203cc80a10e9a0ef1e809b625d037231da3c3abf075e35431a324ca9","combined_total":442000.0,"contract_count":2},"published":true,"created_at":"2026-05-27T12:10:41.988551Z","related_entity_type":null,"related_entity_id":null,"reviewed_by":null,"reviewed_at":null,"reviewer_notes":null,"source_document_ids":null}
