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":"Columbia Gas","contracts":[{"id":"94f811eb-3dcd-4924-8052-dd26830600a9","date":"2017-03-06","amount":354445.69,"department":"Unknown"},{"id":"eb21c5fd-3f12-4e8b-9b24-5394bd9b958b","date":"2017-03-09","amount":120311.0,"department":"Unknown"},{"id":"dd28765a-39de-4045-aa77-575ff5960890","date":"2017-04-24","amount":36054.03,"department":"Unknown"}],"window_days":90,"content_hash":"8b3c54f38bb2247b1b1307663cf5f3a075658a49866f3de1082901c3b506cfb0","combined_total":510810.72,"contract_count":3},"published":true,"created_at":"2026-05-27T12:10:40.987226Z","related_entity_type":null,"related_entity_id":null,"reviewed_by":null,"reviewed_at":null,"reviewer_notes":null,"source_document_ids":null}
