Without complying with the requirements of CMC 3.16.120 and 3.16.130, the purchasing officer may procure an item or service if such item or service is essentially unique and can only be met by a single patented, copyrighted or proprietary article or unique process or skill set available from a single or sole source. Nonexclusive examples of acceptable sole-source purchases are equipment for which there is no comparable competitive product, a component or replacement part for which there is no commercially available substitute and which can be obtained only from the manufacturer, or an item where compatibility with supplies, equipment, materials, general services or processes already in use by the city is the overriding consideration. (Ord. 672 § 2, 2017).
