The Department of General Services Facilities Division (DGS-FD) relies on automated access control arms to provide security and revenue tracking at our District-owned parking facilities. The T2 Systems access control arms provides DGS-FD with the ability to manage employee/visitor parking spaces, the flow of traffic and additional security for the building as a whole. DGS-FD has researched other CBE certified access control arm companies to complete this repair; however, since T2 Systems (Exhibit A- Letter of Proprietary Hardware/Software) manufactures their own access control arm equipment and associating software, which has previously been installed at other District-owned parking facilities, the determination is made that T2 Systems is the only company able to perform this repair.
