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":"Brandstetter/Carroll","contracts":[{"id":"4e6e0d09-bd9e-4b3d-9f5c-32245b86731f","date":"2016-10-06","amount":60300.0,"department":"Unknown"},{"id":"52928e0e-4aa1-41fb-8795-4c068355f017","date":"2016-10-12","amount":39600.0,"department":"Unknown"},{"id":"acd6aa5b-2c39-4ca8-9014-3cf421f497cf","date":"2016-10-12","amount":16000.0,"department":"Unknown"},{"id":"269f8b91-d1ed-42ad-a71a-4e8948b3da72","date":"2016-11-15","amount":46000.0,"department":"Unknown"}],"window_days":90,"content_hash":"5315c464364df6f3f50bccd6e99a02ca64e6140bf95be547c1d2c98b1a9b5957","combined_total":161900.0,"contract_count":4},"published":true,"created_at":"2026-05-27T12:10:40.831705Z","related_entity_type":null,"related_entity_id":null,"reviewed_by":null,"reviewed_at":null,"reviewer_notes":null,"source_document_ids":null}
