Specifications include, but are not limited to: Seeking to establish a Preapproved Vendor List (PVL) for Security Services which will be available for use by state agencies under the purview of the PPRB (Contracting Agencies). OPSCR invites bids from qualified agencies who provide security guards (Vendors) for placement on the list. After PPRB establishes the PVL, Contracting Agencies may select and contract with Vendors from the list, avoiding the need for individual procurement. OPSCR is seeking bids for uniformed security guards in four separate categories of service: (1) unarmed foot patrol, (2) armed foot patrol, (3) unarmed vehicular patrol, and (4) armed vehicular patrol. Foot patrol services may include the use of motorized and non-motorized means of transportation as provided by the Contracting Agency (such as golf cart, Segway, or bicycle, etc.). Vehicular patrols will be conducted in a vehicle provided by the contractor.
