Specifications include, but are not limited to: Through this Request for Proposal (RFP) the State of Vermont, through its Office of Purchasing & Contracting (hereinafter the “State”) seeks to pre-qualify information technology (IT) vendors to provide IT professional services in one or more categories of services described in Section 2 of this RFP. Bidders deemed qualified by the State in any one or more service categories under this RFP shall execute the State’s Retainer Contract for IT Professional Services, which is attached to this RFP. The State maintains multiple retainer contracts with vendors in each of the several categories of IT services. The retainer contract establishes (1) the process for a State Agency/Department to engage IT vendors for services in any of their awarded categories (2) the terms and conditions applicable to the vendor’s provision of services when engaged by a State Agency/Department, and (3) the roles and maximum allowable rates applicable to each category of service. As structured, the retainer contract enables State Agencies/Departments to efficiently obtain competitive pricing proposals to meet a business need from multiple vendors that have been pre-qualified in the applicable category of service. At least every two years the State issues this RFP to qualify and/or re-qualify IT vendors in the IT service categories.
