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.
