An award is uncontested when the buyer had no rival offer to weigh: it was made without a competition (direct award, negotiated procedure without a call for tenders, sole-source or advance-notice contract), or a competition was held and only one bid arrived. Every count below is built award by award from the official notices. Awards to individuals are not included.
