## Description

The Centers for Disease Control and Prevention (CDC) intends to acquire annual maintenance/subscription support for existing Government-owned ITASCA 3DEC, FLAC3D, and Griddle perpetual software licenses from Itasca Consulting Group, Inc. The Contracting Officer has determined that only one source is currently known to be capable of satisfying the requirement because the acquisition requires continued maintenance, software updates/upgrades, licensing support, and technical support for the Government's existing proprietary ITASCA licenses.

All responsible sources may submit a quotation or capability information in response to the attached RFQ. Timely responses will be considered by the Government.
