All interested suppliers, contractors and service providers, both current or new, will need to register on the Ion Wave website. We will post more information soon about how to get registered.

In the meantime, the current process will be in effect.

This site contains solicitations for facility improvement projects, miscellaneous large and small equipment, vehicles, information technology services and miscellaneous goods and services.
