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":"Schaefer Contracting","contracts":[{"id":"5e9c1a7c-d336-459d-8ec5-8b4c62a7be9f","date":"2015-09-28","amount":175674.0,"department":"Unknown"},{"id":"5588ba6d-9f6b-49e3-b596-5500c54d9fd0","date":"2015-10-12","amount":183283.0,"department":"Unknown"},{"id":"4e014938-e5b5-4716-9f91-fe6c51468299","date":"2015-11-17","amount":188851.0,"department":"Unknown"},{"id":"f534199d-4207-41fb-bbb9-c621753d0796","date":"2015-12-08","amount":215571.0,"department":"Unknown"}],"window_days":90,"content_hash":"73db7f5b373cfaad9ec690eb1a296cf55c6e8a4b9d4a748d1cb22ce0166e6319","combined_total":763379.0,"contract_count":4},"published":true,"created_at":"2026-05-27T12:10:41.782923Z","related_entity_type":null,"related_entity_id":null,"reviewed_by":null,"reviewed_at":null,"reviewer_notes":null,"source_document_ids":null}
